Abstract:

Mixed mating strategies in plants, such as chasmogamy and cleistogamy, may have evolved to optimize reproductive response to local, often variable, environmental conditions. A 2-year field experiment was conducted to examine the effects of light and nutrient availability on growth and chasmogamous and cleistogamous flower and fruit production in Viola mirabilis, a perennial forest understory herb. Using a factorial design, we examined whether the mode of reproduction or reproductive output of V. mirabilis would be influenced by a repeated fertilizer application and (or) gradual shading with ar

Abstract:

Cleistogamy involves structural, developmental, and functional differences between the open (chasmogamous) and closed (cleistogamous) floral forms produced by a species. Functional differences relate to the breeding system: progeny is obtained partly by obligate selfing, cleistogamous flowers and, at least potentially, by outcrossing, chasmogamous flowers. This study addresses theoretical predictions about the breeding system in Centaurea melitensis L. Comparative analysis of cleistogamous and chasmogamous flower heads produced by this species was based on studies of the morphological features

Abstract:

Introduced plants may compete for pollination with native plants, resulting in reduced fruit or seed set. In this study, I use several techniques to assess whether the invasive plant Euphorbia esula L. (leafy spurge, Euphorbiaceae) reduces the pollination success of chasmogamous flowers of the native plant Viola pedatifida G. Don (prairie violet, Violaceae), which has chasmogamous and cleistogamous flowers. Euphorbia pollen was found on most Viola stigmas, suggesting the potential for competition. Additionally, application of Euphorbia pollen to Viola stigmas prior to conspecific pollen reduce

Morphological differences between chasmogamous and cleistogamous flowers are discussed and illustrated. The phenomenon of flower dimorphism appears to be of limited taxonomic value but nevertheless supports the idea of an affinity between the L. laxa, L. pungens and L. leptoloba groups.

The aim of this study is to identify flower characteristics that facilitate or prevent autogamous or allogamous processes.

Abstract:

The maintenance of outcrossing in cleistogamous plants that produce both open, facultatively outcrossing chasmogamous (CH), and closed, obligate selfing cleistogamous (CL) flowers is puzzling because CL reproduction is thought to be more reliable and less costly. A possible explanation for the maintenance of CH flowers is the avoidance of inbreeding depression. However, inbreeding depression for cleistogamous species has rarely been quantified. In this study, we estimate levels of inbreeding depression in plants from three populations of Triodanis perfoliata (L.) Nieuwl., a dimorphic cleistoga

Few studies of inbreeding depression have focused on species producing both showy, chasmogamous (CH) flowers and self-pollinated, cleistogamous (CL) flowers. The goals of this investigation were to measure the level of inbreeding depression in the North American violet, Viola canadensis L., and to determine if any fitness differences were linked to floral type (CH versus CL) rather than to cross type (self versus outcross). Hand pollinations were carried out to produce self- and outcross-pollinated CH progeny, and CL seeds were also collected. In a greenhouse, selfed and outcrossed CH flowers

How plants respond to climatic perturbations, which are forecasted to increase in frequency and intensity, is difficult to predict because of the buffering effects of plasticity.

Abstract:

Amphicarpy, an adaptive trait whereby both aerial and underground fruits are formed on the one plant, occurs in several plant taxa, notably the Phaseoleae legumes. Amphicarpic species offer the dual potential benefits of enhanced persistence through their underground seed, combined with ease of harvest of their aerial seed. While amphicarpy has been reported in several endemic Australian tropical legumes, information on the trait is sparse. The objective of the current research was to compare aerial and underground reproductive structures in amphicarpic tropical legumes from four different sub

Abstract:

AbstractViola uliginosa(bog violet) is a declining species throughout its range due to – mostly anthropogenic – drying out of the wet habitats it occupies. Using AFLP markers, we aimed to estimate the genetic diversity in Polish populations, that may give an insight into the situation of plant populations facing rapid loss of natural habitats.Bog violet from several dispersed Polish populations is generally characterized by very low genetic diversity (HT= 0.048), even lower than several other endangered violets; therefore, we suggest that it should preserve at least EN rank in the red lists/re

Abstract:

In the forest-steppe zone of Western Siberia, a comparative study of seed productivity, flowering features, fruit and seed morphology, pollen fertilization ability was conducted for the first time in representatives of the Hosta Tratt genus: H. decorata, H. sieboldiana, H. lancifolia, H. albomarginata, H. crispula, H. kikutii, H. montana, H. rectifolia, H. undulata and varieties Golden Tiara, Night before Christmas, and Stiletto. It is noted that the reproductive potential and fertility of pollen in 9 species and 3 varieties of host have intraspecific and varietal specificity and are associate

Abstract:

Peanut is one of the most important crops in the Fabaceae Lindl. (Leguminosae L.) family. South America is considered to be the homeland of peanut, but now this crop is cultivated in America, Africa, Australia, Europe and Asia. The modern phylogenetic system of the genus Arachis L. includes 79 wild species and one cultivated species of common peanut (A. hypogaea L.). Diploid species contain 2n = 20 chromosomes of the A, B or D genome, tetraploids have A and B genomes. The А and В genomes are sequenced. Special biological features of all peanut varieties are the presence of chasmogamous and cle

Abstract:

Abstract Background Transcription factors act as important regulators of transcription networks. Basic leucine zipper (bZIP) transcription factors have been shown to be involved in multiple biological processes in plants. However, no information is available for the bZIP family in Cleistogenes songorica, which is an important xerophytic and allotetraploid grass in desert grasslands. Results In this study, 86 CsbZIPs were identified in the allotetraploid C. songorica genome. For location analysis, CsbZIPs were distributed evenly across two subgenomes of C. songorica.

Abstract:

Abstract Background Cleistogamic flowers are a main barrier in pollen dispersal for cross-pollination necessary in wheat hybrid breeding. The aim of our study was to gain new knowledge on the biology of wheat flowering, in particular on the differences between the cleisto- and chasmogamic forms which has certainly cognitive significance, but it can also be used in practice when seeking a female and male ideotypes for cross hybridization. Results We characterized the most significant features defining the flowering specificity in two wheat cultivars with contrasting tendency to cleistogamy: Pik
