Drought and temperature stresses impact pollen production and autonomous selfing in a California wildflower, Collinsia heterophylla

Ecology and Evolution, 2023
Ongoing climatic changes have altered growing conditions for plants by limiting water availability and inducing unprecedented temperature increases, eliciting plant functional responses that compromise floral trait expression, reduce pollen production ...

Evolution of the Selfing Syndrome in Arabis alpina (Brassicaceae). [PDF]

PLoS ONE, 2015
The transition from cross-fertilisation (outcrossing) to self-fertilisation (selfing) frequently coincides with changes towards a floral morphology that optimises self-pollination, the selfing syndrome.

Evaluation of the symmetric effect of antagonists in the floral morphs of the distylic shrub Bouvardia ternifolia: a field study

Botan‪ical Sciences, 2018
Background: Heterostyly is a genetic polymorphism characterized by a system of sporophyte auto-incompatibility in which the plant populations show two (distyly) or three (tristyly) floral morphs.

Crop yield mediated by honeybees in a star fruit orchard exhibiting atypical distyly

Acta Botânica Brasílica, 2021
The dependence of commercial crops on pollinators is closely related to their reproductive strategies and has direct impacts on production yields. Fruit production of Averrhoa carambola, the star fruit, is highly dependent on bee pollination.
