Floral Biology and Pollination Ecology ofDesmos chinensis(Annonaceae): Assessing the Efficacy of Floral Synchrony for Promoting Xenogamy [PDF]
International Journal of Plant Sciences, 2015 Premise of research. Early-divergent angiosperms typically possess hermaphroditic flowers but often lack any biochemically mediated self-incompatibility mechanism. Although outcrossing is generally promoted in these taxa by protogyny, which is effective for precluding autogamy (self-fertilization within a flower), other mechanisms are necessary to ...

Genetic differentiation between two varieties of Oreocharis benthamii (Gesneriaceae) in sympatric and allopatric regions. [PDF]
Ecol Evol, 2020 Introgression between closely related species occurs commonly where their distributions overlap, leading to their becoming more morphologically and genetically similar. However, few of these studies have looked at intraspecific cases, especially in plants. Here, we report a reverse situation that the genetic variance between two varieties of Oreocharis

Ornamental Plant Research, 2022 Several examples of androdioecy appear to have evolved from dioecy and have low male frequency (< 0.5). However, the evolutionary pathway to androdioecy in Oleaceae may come from hermaphroditism. Osmanthus fragrans L.

Variability in mating strategies in a widespread cactus in the Chihuahuan Desert
Nordic Journal of Botany, Volume 2022, Issue 12, December 2022., 2022 Opuntia is the most diverse and widespread genus in the Cactaceae; several species have broad distribution ranges and have successfully adapted to distinct habitats. One explanation for their success is the diversity of their reproductive systems. Opuntia macrocentra is one of the most common widespread species in North American deserts.

Journal of Systematics and Evolution, Volume 60, Issue 5, Page 998-1011, September 2022., 2022 Distyly in Hedyotis bodinieri (top left, pin morph; lower left, thrum morph) and growth of Hedyotis vachellii pollen (thrum morph) on the stigma of Hedyotis acutangula (pin morph). Abstract Breakdown of self‐incompatibility increases opportunities for both self‐fertilization and interspecific hybridization, although the latter is dependent on the ...

Ecology and Evolution, Volume 12, Issue 3, March 2022., 2022 Cymbidium aloifolium is a perennial, epiphytic orchid found in the tropical regions of South Asia. Its oil‐rewarding flowers are invariably pollinated by a non‐oil bee, Apis cerana indica. The study highlights the mechanism and traits that establish floral constancy and pollination mutualism. Photo: Arjun Adit Abstract So far, oil‐rewarding flowers are

Floral traits and reproductive success variation among inflorescence orders in Eryngium maritimum
Plant Biology, Volume 24, Issue 2, Page 249-258, March 2022., 2022 Eryngium maritimum (Apiaceae L.) is a strongly entomophilous species that displays morphometric and reproductive differences among capitula located in different whorls, suggesting functional differences at intra‐individual level. Abstract Eryngium maritimum L. is considered a key species in dunes of the western Mediterranean. Although Northern European

Batesian mimicry in the nonrewarding saprophytic orchid Danxiaorchis yangii
Ecology and Evolution, Volume 11, Issue 6, Page 2524-2534, March 2021., 2021 The study provide detailed evidence that Danxiaorchis yangii simulates the visual signals of Lysimachia alfredi through Batesian mimicry, thereby deceivingly attracting Dufourea sp. Abstract Batesian mimicry, a type of deceptive pollination, is a complicated strategy used by nonrewarding plants to attract pollinators, but some hypotheses concerning ...
