Abstract:

Abstract Cassava (Manihot esculenta L. Crantz) plants of ‘CMC-40’ and ‘CMC-92’ were grown over a 3-year period with annual harvests at the end of each growing season. Root tissues were divided into peel (secondary phloem with the thin cork tissue layer removed) and up to three parenchymatous tissue age groups. Up to 40% of the starch concentration can be deposited in root parenchymatous tissue. Root starch is permanently removed from parenchymatous tissue of older roots, probably in association with new foliage growth at the start of a new growing season. As a result of periods of little or no

Mucilage extracted from the parenchymatous and chlorenchymatous tissues of Opuntia robusta were obtained using water or ethanol as the extraction solvent. The changes in the different tissues by using different extraction solvents were evaluated via scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) and Raman spectroscopy; in addition, the effect of mucilage coating on the various quality characteristics of tomato (Lycopersicum sculentum) was evaluated. The SEM results showed that the mucilage extracted from the parenchyma had a higher aggregation level that the mucilage

Abstract:

Diplolepis nodulosa (Beutenmüller) induces small, single-chambered, prosoplasmic galls in stems of Rosa blanda Ait. Gall initiation begins when adult females deposit a single egg into the procambium of R. blanda buds. Pith cells at the distal pole of the egg lyse forming a chamber into which the hatching larva enters. Cells lining the chamber differentiate into nutritive cells, which serve as the larval food. Gall growth is characterized by the proliferation of parenchymatous nutritive cells causing gall enlargement. A separate gall vasculature does not form, but instead, gall tissues are irri

ABSTRACTNumerous permineralised, complex medullosan pollen organs are described from Middle and Upper Pennsylvanian sediments of North America. Together with a reinvestigation of type specimens for the previously described species, these provide the basis for fully characterising internal structure and external morphology, and for recognising structural homologies among all medullosan synangia. All medullosan pollen organs, simple and complex, can be interpreted as consisting of sporangial tubes that are embedded in parenchymatous and sclerenchymatous ground tissue, and that have vascular bund

This study investigated the relationship of stem anatomy to differences in rooting ability between Quercus bicolor Wild. and Quercus macrocarpa Michx. cuttings. Quercus bicolor cuttings were found to have a significantly greater proportion of parenchymatous gaps in the sclerenchyma sheath over a 9-week period compared with Q. macrocarpa cuttings. In Q. macrocarpa, the percentage gap was generally low, coinciding with the low percentage rooting observed in this species. Percentage rooting correlated well (r2 = 0.75) with the percentage parenchymatous gap in the perivascular region of Q. bicolor

Abstract:

Differentiation of the particular tissues in shoots inhibited in growth by chlormequat occurs differently than in vigorously growing ones. After the end of elongation growth, in the subapical part of shoots sprayed with chlormequat the cortex extends and secondary xylem develops less intensively, this leading to an increased participation of parenchymatous tissue in the stem.

Abstract:

Xylem always develops within xylem fascicles, and the phloem either comprises phloem fascicles or is dispersed. Xylem and phloem fascicles may be encircled by a sheath of cells different from cells of the interfascicular tissue. The interfascicular tissue is either homogeneous, i.e., consisting of fibers, or heterogeneous, i.e., formed of fiber aggregates and a parenchymatous and (or) sclerenchymatous intrusive network. This network is interpreted as modified pith. A true pith is often present, and four kinds of true pith are recognized.

Stem lesions in sunflower caused by Albugo tragopogonis (Pers.) S.F. Gray developed individually from primary infections and did not result from a systemic infection.

In petioles parenchymatous tissue was heavily colonized in contrast to lightly colonized collenchymatous hypodermis. The middle lamellae of cells in infected tissue were dissolved, and cells degenerated and eventually collapsed. St

Gynoecial placentation of Solanum tuberosum L. is axile with each parenchymatous placenta covered with numerous ovules.

Continued cell division and subsequent cell enlargement result in expanded placental projections, which separate the developing seeds from one another and form an interface with the inner pericarp within 10 – 12 days after pollination. Eventually, the placenta fills the remaining ovarian locular space and embeds the se

Abstract Neurocysticercosis (NCC) is classified as a neglected tropical disease, which affects mainly Latin America and Africa in spite of some reports in North America and Europe. NCC represents the cause of up to 30% of the reported cases of epilepsy in endemic countries. The NCC injuries present direct relation to the development stage, location, and number of parasites as well as to the host immune response.

Only the fragments cultured in October reacted. The neoformations only appeared on calluses that had not been subcultured for 7 months. Primary nodules arising on these calluses were removed and subcultured on the same medium either in the dark or in the light. In the dark only, they produced secondary nodules, which w

The embryogenic callus, which is embryoidal in origin, was made up of normal parenchymatous tissue toward the centre of a clump of cells and numerous proembryoidal cells on the periphery of the callus mass. Embryogenesis appeared to begin in single cells on the periphery of the callus and from cells on the surface of existing proembryoids. Embryo initials could be recognised by their conspicuous starch contents and by their thickened walls, which lack pla

There was a good correlation between the thickness of the cortical parenchymatous tissue in leaves and young stems and the ability of a plant to maintain a less negative water potential in conditions of high atmospheric humidity.

Development of living organisms is characterized by self-organization, which results in ordered cell and tissue patterns. Xylem formation in callus tissue may serve as a model to study these phenomena. Applying auxin on the apical transverse cut surface of willow shoot segments stimulates the proliferation of callus with an unorganized cell arrangement. In some areas of callus, the cells form an ordered system and partly differentiate into tracheary elements. Below the cut surface a zone of initially unorganized parenchymatous cells is produced by the cambium. Later, some of the cells formed o

Lipara lucens Meigen (Diptera, Chloropidae) is a monophagous herbivore of the common reed, Phragmites australis Cav. (Trin.) ex Steud. (Poaceae), on which it induces typical cigar-shaped galls. In this paper, the anatomy and histochemistry of galls, cultivated in a greenhouse and collected in the field, were examined. Gall growth takes place while the larva feeds outside the actual developing gall. During gall growth, internode elongation is reduced. Internally, the pith parenchyma, destined to become the nutritive tissue, proliferates instead of degenerating as is seen in uninfested stems. Th
