Abstract:
The special mixed reproductive system, i.e., the ability of an individual plant to develop both open, chasmogamous (CH) flowers adapted to cross-pollination and closed, cleistogamous (CL) flowers with obligate self-pollinating, is a common phenomenon in Viola L. In most sections of Northern Hemisphere violets, cleistogamy is seasonal, and CH and CL flowers develop sequentially in the season. Non-seasonal cleistogamy (simultaneous) is a rare phenomenon in rostrate violets. In the current study, we focused on modification of the CH/CL mating system in V. caspia by environmental conditions, resul

Abstract:
Cleistogamy is a type of self-pollination that relies on the formation of a stigma-enclosing floral structure. We identify three homeodomain-leucine zipper IV (HD-Zip IV) genes that coordinately promote the formation of interlocking trichomes at the anther margin to unite neighboring anthers, generating a closed anther cone and cleistogamy (flower morphology necessitating strict self-pollination). These HD-Zip IV genes also control style length by regulating the transition from cell division to endoreduplication. The expression of these HD-Zip IV genes and their downstream gene, Style 2.1 , wa

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:
<i>Colobanthus quitensis</i> forms chasmogamic and cleistogamic flowers. Their structure signals the possibility of both cross-pollination and self-pollination. In favorable conditions (natural or laboratory), flowers open creating a possibility for cross-pollination. The occurrence of cleistogamy in the investigated species may be conditioned by abiotic factors: low temperature, high air humidity, and strong wind. In closed flowers, a part of pollen grains reaches the stigma surface, and the rest remains inside the microsporangium. Pollen grains germinate on the stigma surface or

Abstract:
Background Wheat is one of the most important staple crops worldwide. Fusarium head blight (FHB) severely affects wheat yield and quality. A novel bread wheat mutant, ZK001, characterized as cleistogamic was isolated from a non-cleistogamous variety Yumai 18 (YM18) through static magnetic field mutagenesis. Cleistogamy is a promising strategy for controlling FHB. However, little is known about the mechanism of cleistogamy in wheat. Methods We performed a FHB resistance test to identify the FHB infection rate of ZK001. We also measured the agronomic traits of ZK001 and the starch and total solu

Abstract:
Early-flowering species may be especially susceptible to occasional pollen limitation and, therefore, may benefit from a mixed-mating strategy that provides reproductive assurance. We studied cleistogamous (CL) and chasmogamous (CH) fruit set of spring-flowering Viola praemorsa Dougl. ex Lindl. along an elevational gradient in the Rocky Mountains, testing whether pollen limitation or allocation to CL reproduction covaried with timing of flowering onset, within and across sites. Contrary to predictions, we found no pollen limitation of reproduction at any site, and variation among sites in the

The population dynamics of transposons in self- and cross-fertilizing plant populations are investigated both theoretically and empirically. Models were developed to evaluate the influence of host breeding system on transposon populations. Modeling results suggest that the selfing rate is likely to have important effects on the abundance and polymorphism patterns of transposable elements in plant genomes. A primary characterization of diversity and abundance of transposons in the self-pollinating species Arabidopsis thaliana was conducted using genomic sequencing data, providing strong evidenc

La cléistogamie est un régime de reproduction mixte particulier – contrairement aux régimes mixtes classiques où un seul morphe floral effectue l'auto- et l'allofécondation, les espèces cléistogames produisent des fleurs fermées (cléistogames, CL) qui sont obligatoirement autofécondées et des fleurs ouvertes (chasmogames) qui sont potentiellement allofécondées. D'autres particularités sont associées aux régimes cléistogames : i) les fleurs fermées ne peuvent pas exporter de pollen (pollen discounting total), résultant avec l'absence de l'avantage automatique de l'autofécondation, ii) les couts

Abstract:
Dimorphic strategies for sexual reproduction are common in plants and their evolutionary dynamics is one of the central themes in plant evolutionary biology. True cleistogamy, or CLOP, is one such strategy where individuals use two types of flowers for reproduction: normal chasmogamous (or OP) flowers, which are open for insect pollination and so able to outcross; and reduced, closed cleistogamous (or CL) flowers specifically modified for self-pollination.

Soybean, which has many foods, feed, and industrial raw material products, has relatively limited genetic diversity due to the domestication practices which mainly focused on higher yield for many centuries. Besides, cleistogamy in soybean plant reduces genetic variations even further.
