Seasonal and Simultaneous Cleistogamy in Rostrate Violets (Viola, subsect. Rostratae, Violaceae) [PDF]
Plants, 2021 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 ...

Breeding system and geospatial variation shape the population genetics of Triodanis perfoliata [PDF]
Ecology and Evolution, 2022 Both intrinsic and extrinsic forces work together to shape connectivity and genetic variation in populations across the landscape. Here we explored how geography, breeding system traits, and environmental factors influence the population genetic patterns

Engineered Cleistogamy in Camelina sativa for bioconfinement. [PDF]
Hortic Res, 2023 AbstractCamelina sativa is a self-pollinating and facultative outcrossing oilseed crop. Genetic engineering has been used to improve camelina yield potential for altered fatty acid composition, modified protein profiles, improved seed and oil yield, and enhanced drought resistance.

Heteroblastic Inflorescence of Lamium amplexicaule L. in Egyptian Flora [PDF]
Plants, 2023 Lamium amplexicaule L. (Family: Lamiaceae) is a cosmopolitan weed whose eradication is challenging. The phenoplasticity of this species is related to its heteroblastic inflorescence, which has not received adequate research worldwide in its morphological

Identification of candidate genes responsible for chasmogamy in wheat [PDF]
BMC Genomics, 2023 Background The flowering biology of wheat plants favours self-pollination which causes obstacles in wheat hybrid breeding. Wheat flowers can be divided into two groups, the first one is characterized by flowering and pollination within closed flowers ...

miR167d-ARFs Module Regulates Flower Opening and Stigma Size in Rice [PDF]
Rice, 2022 Flower opening and stigma exertion are two critical traits for cross-pollination during seed production of hybrid rice (Oryza sativa L.). In this study, we demonstrate that the miR167d-ARFs module regulates stigma size and flower opening that is ...

Chasmogamy and entomophily in Burmannia disticha (Burmanniaceae) [PDF]
Frontiers in Plant Science, 2023 Burmannia shows a set of floral traits that suggest elaborate mechanisms of animal-mediated pollen transfer. These include flower coloration, septal nectaries and a long and narrow floral chamber.

Spikelet movements, anther extrusion and pollen production in wheat cultivars with contrasting tendencies to cleistogamy [PDF]
BMC Plant Biology, 2021 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 ...

A novel bat pollination system involving obligate flower corolla removal has implications for global Dillenia conservation. [PDF]
PLoS ONE, 2022 The Dilleniaceae is known to produce nectarless flowers pollinated by bees, but the fact that bats ingest Dillenia biflora pollen led us to question pollination assumptions for these trees. We aimed to identify the pollinators of D.
