In the world of plants, love is complex, and new research reveals a surprising twist in how some plants overcome their self-incompatibility to self-fertilise.
There’s a common belief that hybridization of plants can aid invasions through adaptive introgression. This is where a hybrid breeds with one of its parent species, so that the parent species eventually adopts a new...
Heterostyly, a term referred to plant species comprising either two (distyly) or three (tristyly) self-incompatible floral morphs that differ reciprocally in the positions of stigmas and anthers (i.e. reciprocal...
Success in reproduction is subject to the successful initiation as well as successful completion of a chain of consecutive events starting from flower formation and ending with viable seed production. A recent article...
Flowering plants display an extensive range of adaptive floral forms, which are often correlated with their mating systems. The maintenance of contrasting strategies such as those adopted by obligate outcrossers...
In the mustard family, which includes the important crop Brassica (rapeseed/canola) and the model plant Arabidopsis, the surfaces of the female stigmatic cells are dry. These cells – on which the pollen grains land...
Results show that full-length SRKb is localized primarily at the plasma membrane and the secreted eSRKb product is not required for self-incompatibility.
Preservation of cultivar purity is a particular challenge for plants that are self-incompatible and have easily germinating seeds and vigorously spreading rhizomes.
