Abstract:

In leaves of the periwinkle plant (Catharanthus roseus (L.) G. Don) idioblasts are randomly distributed in the mesophyll. They are distinguishable from ordinary palisade and spongy parenchyma cells as large, refractile, and autofluorescent cells. Density gradient centrifugation of protoplasts derived from leaves resulted in fractions enriched in idioblast protoplasts. Analysis of indole alkaloid composition by high pressure liquid chromatography has shown that idioblasts are enriched in vindoline and catharanthine relative to other mesophyll cells. The significance of these observations for attempts to produce specific indole alkaloids in cell cultures is discussed.

Full text

Abstract:

Histological analysis of Ruta graveolens L. roots and in vitro grown cell suspensions revealed idioblasts with vacuoles containing clusters of droplets thought to be the storage compartment of acridone alkaloids. These idioblasts contained numerous vacuoles of varying sizes rather than the large, single, central vacuole characteristic of most adjacent parenchyma cells. The structure of idioblasts in roots and suspension cultures was identical. Treatment of suspension cultures with fungal elicitors known to increase alkaloid accumulation greatly did not affect the structure of idioblasts.

Abstract:

Several specimens of Lauraceae fossil wood from the Cenozoic of Greece (southern part of Lesbos), the Czech Republic (Kadaň-Zadní Vrch Hill and Jáchymov), and Hungary (Ipolytarnóc) were studied. When considering whether they belonged to the speciose fossil wood genus Laurinoxylon, we reviewed the literature and data from InsideWood on fossil and modern woods. As a result, we propose criteria for excluding a fossil Lauraceae wood from Laurinoxylon and list the species that should be excluded from this genus. The criteria (filters) proposed to exclude a genus from having relationships with Laurinoxylon are: A. Axial parenchyma features: A1. Marginal axial parenchyma, A2. Aliform to aliform-confluent paratracheal parenchyma. B. Ray features: B1. Rays higher than 1 mm, B2. Exclusively homocellular rays, B3. Rays more than 5 cells wide, B4. Rays storied. C. Porosity features: Ring-porous. D. Idioblasts: Absence of idioblasts. Based on the distribution of idioblasts, we recognize four groups in Laurinoxylon (Type 1 - with idioblasts associated only with ray parenchyma cells, Type 2a - with idioblasts associated with both ray and axial parenchyma, Type 2b - with idioblasts associated both with rays and present among the fibres, and Type 3 - with idioblasts associated with ray and axial parenchyma and also among the fibres) and list the extant genera with features of those groups. Such grouping helps with interpreting the relationships of fossil lauraceous woods with extant genera. We discuss the Oligocene–Miocene European species that belong to these Laurinoxylon groups, noting that some warrant reassignment to different genera or even families. Future studies are needed to determine whether new genera should be established to accommodate these species. We propose the new combination Cinnamomoxylon variabile (Privé-Gill & Pelletier) Mantzouka, Karakitsios, Sakala & Wheeler.

Full text

Abstract:

X-ray microprobe analysis of freeze-fractured Lemna fronds has shown that zinc (Zn) and cadmium (Cd) are not incorporated into oxalate crystals in idioblasts, whereas strontium (Sr) is readily incorporated as an alternative to calcium (Ca). Ca and Sr are uniformly distributed throughout the crystal bundle when both elements are present in the nutrient solution. However, in neighbouring, non-idioblast cells Sr (but not Ca) may also be incorporated into globular deposits of less than 1 �m diameter. These globules contain the mineral elements potassium and phosphorus and their composition appears to be identical to that of phytate globules which contain Zn or Cd under conditions of Zn or Cd toxicity.

Full text

Abstract:

In developing leaflets of Stylosanthes guianensis (Aubl.) Sw., twin prismatic calcium oxalate crystals form in adaxial and abaxial epidermal crystal idioblasts. These cells eventually die and collapse, leaving the crystals embedded in a matrix of cutin and cell-wall materials. Adaxial crystal idioblasts develop above large conical cells that, in turn, are interspersed among smaller, multiple-layered palisade parenchyma. Abaxial crystal idioblasts develop beneath a uniseriate layer of large horizontally branched cells abutting the abaxial epidermis. Spongy parenchyma occupies the middle mesophyll above the layer of branched cells. The abaxial crystals and the branched cells of the lowermost mesophyll develop simultaneously. Adaxial crystals and the conical cells develop later and in conjunction with each other. In mature leaflets, the adaxial and abaxial crystals and their associated collapsed crystal idioblasts form networks, the interstices of which are occupied by either single stomates and accompanying epidermal cells (adaxial) or clusters of stomates and accompanying epidermal cells (abaxial). Epidermal crystals are known from other Leguminosae; however, to our knowledge this is the first report where epidermal crystal development involving cell death and collapse is correlated with two types of specialized mesophyll cells.

Abstract:

Tissue-culturedexplantsofDieffenbachiamaculate`Exotic Perfection', D.`Snow Flake', and D. × `Tropic Breeze' were grown on ebb-and-flow trays subirrigated with nitrogen (N) at 50, 200, or 800 mg·L-1 using a water-soluble fertilizer 17N–2.1P–15.7K for 10 weeks in a shaded greenhouse under a maximum photosynthetic photon flux density of 285 μmol·m-2·s-1. Plants were then transferred to interior rooms under a light level of 8 μmol·m-2·s-1. Samples of the midrib were taken from the first mature leaf of plants before being placed indoors and also from the first mature leaf of plants 8 months after growing indoors. Counts of calcium oxalate crystal idioblasts in cross-sections of the basal midrib using polarized light microscopy showed that the number of crystal idioblasts was higher in all three cultivars fertigated with 200 mg·L-1 N than those fertigated with either 50 or 800 mg·L-1 N. The number of crystal idioblasts in each cultivar grown under 8 μmol·m-2·s-1 was about 50% of the number detected when plants were grown under 285 μmol·m-2·s-1. `Snow Flake' had the highest number of crystal idioblasts with counts up to 60 per cross-section, whereas `Exotic Perfection' had the lowest with only 30 per cross-section. This study shows that in addition to cultivar differences, light intensity and N can significantly affect calcium crystal formation, and the highest number of crystal idioblasts occurred when Dieffenbachia cultivars were grown under optimum conditions.

Full text

Abstract:

Two legume trees largely known as tannin producers — Dimorphandra mollis Benth. (Caesalpinioideae) and Stryphnodendron adstringens (Mart.) Coville (Mimosoideae) — were used as models to elucidate the morphology and ontogeny of tannin cells. Vegetative parts of plants were processed for observation using light and electron microscopy (scanning and transmission). Idioblasts, found even in young plants of both species, and secretory trichomes, observed in vegetative buds of mature plants of S. adstringens, are responsible for tannin production. The tanniniferous idioblasts originate from protoderm and also from ground meristem cells. The ground meristem proved to be the best place to study the development of tanniniferous idioblasts at different stages of development, which allowed us to monitor the production and accumulation of tannins in the same tissue. Our data indicate that there is a relationship between the production of tannins and the process of vacuolation of tanniniferous cells. The results also indicate the probable performance of rough endoplasmic reticulum (RER) and plastids in the production of tannins.

Abstract:

ABSTRACT The growing of Piper aduncum for essential oil extraction has increased, but there is a lack of basic information about its management and cultivation, which allows the productivity and quality of the oil, in order to attend the market demands. This study aimed to evaluate the relation between the production of essential oils from P. aduncum and soil water pressure heads (20 kPa, 40 kPa, 60 kPa, 100 kPa and non-irrigated). The assessment comprised the quantification of idioblasts and the production of essential oil extracted from leaves of cultivated plants. The variation in the soil water pressure head alters the amount of idioblasts in P. aduncum leaves, with impacts on the essential oil production. A soil water pressure head range of 20-60 kPa is sufficient for this species to express the highest amount of idioblasts and the highest level of essential oil production. The species adapts itself to different water availability conditions in the soil. Under stress conditions, due to water deficit or excess, the production of essential oil is reduced.

Abstract:

The objective of this study was to determine the effect of height of leaves in the canopy of plants, leaf organic compounds, concentrations of leaf nitrogen and potassium, leaf trichomes and cristalliferous idioblasts densities on the attack intensity of three tomato (Lycopersicon esculentum Mill. cv. Santa Clara) crops by Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and Liriomyza spp. (Diptera: Agromyzidae), under field conditions. The experimental design was arranged in randomized blocks, with three replications, each being one tomato crop. Analysis of variance and the Tukey’s multiple range test (5% significance) were used to test the effect of canopy height, trichome and cristalliferous idioblasts densities on the number of mines produced by T. absoluta and Liriomyza spp. and on the number of T. absoluta eggs. Pearson’s correlation (5% significance) was used to evaluate the relationships between leaf organic compounds, leaf N and K concentrations, leaf trichome and cristalliferous idioblasts densities and the number of mines produced by T. absoluta and Liriomyza spp. and the number of T. absoluta eggs. Highest insect attack occurred in the final stage of the culture. A higher number of Liriomyza spp. mines/leaf was recorded in the lower (1.50) than in the upper (0.02) level of the tomato plants, the opposite was observed for the number of T. absoluta eggs/leaf (0.13 and 0.57, respectively). The number of T. absoluta mines/leaf concentrated more on the median (10.23) and apical regions (8.63) than on the basal (4.93). No significant effect of the trichomes and cristalliferous idioblasts densities of leaves was noted on T. absoluta and Liriomyza ssp. populations. Apparently, the terpenes affected oviposition of T. absoluta while leaf potassium affected Liriomyza spp. attack.

Abstract:

The species Lantana camara, commonly used as ornamental, has spread worldwide becoming one of the world's most important weeds. To develop new methods of control of this plant, it is essential to distinguish it from other species of the same genus, and this is usually accomplished through taxonomic studies of fertile samples. Considering the similarity between L. camara and L. radula, and the consequent difficulty in distinguishing one from the other when only sterile samples are available, this work aimed to investigate the use of the anatomical characteristics of the leaves of both species as tools for supporting correct classification. The leaves of L. camara and L. radula were anatomically examined by light microscopy and scanning electron microscopy. The major differences were observed in the petiole, which presented secretory idioblasts in L. camara. Secretory idioblasts were observed in the leaf blades of L. camara and Crystalliferou idioblasts were found in L. radula. Glandular and nonglandular trichomes as well as the abaxial surface are different in each species. Such results can support the strategies aiming at the control of L. camara without interfering with L. radula.

Abstract:

Crystal-bearing cells or idioblasts, which deposit calcium oxalate, are located in various tissues and organs of many plant species. The functional significance of their formation is currently unclear. Idioblasts in the leaf parenchyma and the development of crystal-bearing cells in the anther tissues of transgenic tomato plants (Solanum lycopersicon L.), expressing the heterologous FeSOD gene and which showed a decrease in fertility, were studied by transmission and scanning electron microscopy. The amount of calcium oxalate crystals was found to increase significantly in the transgenic plants compared to the wild type (WT) ones in idioblasts and crystal-bearing cells of the upper part of the anther. At the same time, changes in the size and shape of the crystals and their location in anther organs were noted. It seems that the interruption in the break of the anther stomium in transgenic plants was associated with the formation and cell death regulation of a specialized group of crystal-bearing cells. This disturbance caused an increase in the pool of these cells and their localization in the upper part of the anther, where rupture is initiated. Perturbations were also noted in the lower part of the anther in transgenic plants, where the amount of calcium oxalate crystals in crystal-bearing cells was reduced that was accompanied by disturbances in the morphology of pollen grains. Thus, the induction of the formation of crystal-bearing cells and calcium oxalate crystals can have multidirectional effects, contributing to the regulation of oxalate metabolism in the generative and vegetative organs and preventing fertility when the ROS balance changes, in particular, during oxidative stresses accompanying most abiotic and biotic environmental factors.

Full text

Abstract:

The taxonomic significance of cypsela features of South American species of Lessingianthus (Vernonieae, Asteraceae) is analysed for the first time and discussed in relation to other genera of the tribe Vernonieae. The morphology of the cypselae of 112 species of the genus were analysed using stereo-, light and scanning electron microscopy (SEM) to evaluate the infrageneric relationships and their reliability as taxonomic markers at a generic level. Characters such as cypsela pubescence, carpopodium structure, crystals and idioblasts on the fruit wall were examined. We established three types of cypsela on the basis of the presence or absence, and type of trichomes. Carpopodium is present in all species of the genus. Crystals are very variable in shape and size, with prismatic (rectangular and hexagonal) and styloid shapes. Idioblasts are present in all of the species, except for two. Cypsela features of Lessingianthus are often widespread in other related genera of Vernonieae. Therefore, these characters are not good taxonomic markers at the genus level, but they are valuable within genera to differentiate related species from one another.

Full text

Abstract:

A comparative study of the leaf micromorphology of Korean Piperales, including medicinal materials, was performed through light microscopy and scanning electron microscopy, to evaluate their taxonomic significance. Piperales possessed both amphistomatic and hypostomatic leaves. The epidermal area ranged from 38 to 5077 μm2, and the stomatal area ranged from 201 to 2129 μm2. The stomatal index on the abaxial surface was higher than that on the abaxial surface. Anomocytic stomata occurred most commonly, but actinocytic, anisocytic, tetracytic, and staurocytic stomata were also found in certain taxa. Secretory idioblasts were found on all taxa studied except Aristolochia. Three main types of trichomes were defined—(1) glandular trichome; (2) simple multicellular trichome; and (3) two-armed multicellular Y-shaped trichome. Although the quantitative data on its own had somewhat limited taxonomic value, the various qualitative characteristics (e.g., epidermal surfaces, stomata types and positions, trichome types and density, and secretory idioblast types) had great taxonomic value. These characteristics might be taxonomically relevant and useful for developing an identification key. Additionally, we evaluated and supported the previous taxonomic system of Korean Asarum, using leaf micromorphological characteristics. Finally, through the application for authentication of herbal medicine, we revealed that leaf micromorphological characteristics can be used for accurate authentication.

Abstract:

Rhamnaceae flowers are notably recognized by their fleshy nectary. Other types of floral secretory structures have been scarcely reported for this family. Thus, the objective of the present study was to update the occurrence of these structures in the family and to contribute to the knowledge of their morphology and systematic significance. To this end, we carried out an extensive bibliographic search on the secretory structures of the family and obtained data for 257 taxa. Additionally, we presented here novel data (surface, anatomy, and ultrastructure) for six species belonging to the main clades within Rhamnaceae. The family has a wide diversity of types of mucilage-secreting structures: epidermis, hypodermis, idioblasts, cavities, and ducts. Mucilage and phenolic idioblasts are widely distributed among the floral organs. Colleters are present in all sampled species, and these are the first reports of their occurrence in floral organs of Rhamnaceae. The information obtained about the structure, secreted content, and occurrence of the secretory structures of Rhamnaceae helped us to understand the assertive folk use of its species. The absence of mucilage and the presence of resin or mucilage cavities and ducts in some taxa may have intrafamily systematic significance.

Abstract:

Epidermal cells are persistent or nonpersistent. In most species the common walls between epidermal and exodermal cells are relatively thick and hydrophobic. Sclerenchyma tissue is generally present in the endodermis, but exodermal sclerenchyma occurs in relatively few species. Between the endodermis and exodermis cortical sclerenchyma may comprise a circumcortical ring, intervening sclerenchyma tissue, or a circumstelar ring. The cortex also contains parenchyma cells and sometimes extracellular mucilage canals, tubular cells, and crystal sacs (crystal idioblasts) other than tubular cells. Periderm is sometimes present. Intermediates between various cell types may occur, creating problems in cell classification.

Abstract:

Secretory structures are an outstanding feature in Primulaceae (Ericales). Such structures are known for their taxonomical and medicinal importance. However, a detailed morphological study of the secretory structures in Primulaceae has been neglected. Selected species for this study belong to Myrsine, a widely distributed genus in Brazil, popularly known as “capororoca”. In this study, we aimed to elucidate the ontogenesis of the secretory structures in the leaves of Myrsine coriacea (Sw.) R. Br. ex Roem & Schult. and Myrsine venosa A.DC. and report, for the first time, on the composition of their essential oils. The following secretory structures are found in M. coriacea and M. venosa: idioblasts, glandular trichomes, and secretory cavities. The development of all secretory structures, which is asynchronous, occurs during leaf expansion and differentiation; therefore, in leaf primordia, the same type of secretory structure could be observed at different stages of differentiation. By the complete expansion of leaf primordia, all secretory structures have reached their full size. Idioblasts are derived from both protodermal and ground meristem cells and they secrete mucilage or phenolic compounds. The glandular trichomes can be peltate, as found in both species, or branched, as found only in M. coriacea. Trichomes are initiated by the enlargement of protodermal cells, followed by their division, and they are completely formed by the end of leaf expansion. Secretory cavities are schizogenous and originated from ground meristem cells. Major components from M. coriacea essential oils were β-elemene, γ-muurolene, and α-cadinene, while the major components of M. venosa essential oils were β-caryophyllene, γ-muurolene, and δ-cadinene.

Abstract:

The objective of this paper was to describe and compare the morphology and anatomy of mature leaves of Mikania glomerata Spreng., Porophyllum ruderale Cass. and Vernonia condensata Baker (Asteraceae) species that have different habits emphasizing their secretory structures. Longitudinal and transversal sections of mature leaf blades of the three species were analyzed at the apex, base, and medium third part of the midvein of the leaf blade and of the margin. M. glomerata had uniseriate glandular trichomes and secretory ducts; P. ruderale had hydathodes and secretory cavities; and V. condensata had idioblasts and uni-and biseriate glandular trichomes.

Abstract:

The present study, conducted during the period 2010- 2011, involved morphological observations and anatomical investigations of horse chestnut (<i>Aesculus hippocastanum</i> L.) leaves with symptoms of damage caused by feeding of larvae of the horse-chestnut leaf miner (<i>Cameraria ohridella</i> Deschka & Dimić). Leaves were collected from trees growing in the city of Lublin (Poland). Microscopic slides were prepared from fresh and fixed plant material. Leaf anatomical features were examined by light microscopy in order to determine the mechanical barrier for feeding pests. Changes were also observed during the progressive damage of the leaf tissues caused by the larvae. Selected developmental stages of the pest are presented in the paper. It has been shown that very thin blades of the mesomorphic leaves of <i>Aesculus hippocastanum</i> produce a poorly developed mechanical barrier in which the following elements can be included: the presence of collenchyma and idioblasts with druses of calcium oxalate, few non-glandular trichomes found close to the leaf veins as well as relatively thin outer walls of the epidermal cells. The cells containing tannins and the oil cells found in the mesophyll may form a physiological barrier. However, foraging leaf miner larvae feed only on the palisade and spongy parenchyma cells, leaving undamaged the cells with tannins as well as the idioblasts with calcium oxalate crystals and oils. The feeding of the pest in the leaf mesophyll leads to the death of the epidermis on both sides of the lamina and to drying of the parts of the leaves in the area of the mines.

Abstract:

Interest in the development of anatomical and morphological authenticity criteria of a number of food products of plant origin is growing due to their falsification. A fairly common falsification is the substitution of laurel noble leaves (Laurus nobilis L.) with similarly alike leaves of medicinal laurel cherries (Laurocerasus officinalis M. Roem.), full or partial replacement of long leaf tea with vegetative organs of other families plants. The microscopy method in combination with histochemical reactions to biologically active substances can become promising not only for identification, but also for assessing the quality of individual food products of plant origin. The aim of the study was to develop anatomical and morphological criteria for the identification and quality of food products of plant origin on the example of black long leaf tea and laurel leaf. Diagnostic features allowing identification and detection of laurel leaf falsification by cherryl leaves are leaf area, stomatal apparatus type, number and location of essential oil containers, tannins localization, calcium oxalate crystals shape and location. The criterion for qualimetric identification of laurel leaf is the number of calcium oxalate crystals and the filling of containers with essential oil. A strong positive link between the number of filled essential oil containers and the content of essential oil in the leaves were established. A diagnostic feature of tea leaf is the presence of idioblasts. It is advisable to use the number of idioblasts, hairs and drusen of calcium oxalate crystals per unit area to identify, detect outgrowing, assess the degree of maturity of the tea leaf and the quality of black tea, the value of which is associated with the content of water-soluble extractive substances and tannin..

Abstract:

The paper provides information about histochemical staining reactions in leaves and embryos of 'Coqueiro Anão' (Cocos nucifera). It was compared in vitro coconut and autotrophic palm leaves. Reactions for insoluble polysaccharides and acidic compounds, protein, extractable lipids, lignin and other classes of compounds were tested using histochemical tests. None sample gave positive reaction for lignin and phenolic compounds. All the samples gave positive reaction for protein, starch and insoluble polysaccharides while acidic compounds were positive only in in vitro leaves. Both in vitro and autotrophic leaves gave positive reaction for lipids showing presence of cuticle even in in vitro leaves. Only autotrophic palm leaves showed idioblasts containing calcium oxalate crystals.
