WebIt is shown that pistil-derived galactose-specific Ca2+-independent lectins from the respective other morph can overcome self-incompatibility in heterostylous L. perenne and suggests that lectins participate in signaling pathways for recognition at the pollen-stigma interface and are involved in the regulation of the self- incompatibility process in … WebDec 13, 2024 · Heteromorphic self-incompatibility can prevent self- and intramorph fertilization while favouring intermorph mating and the maintenance of morph-ratio … howells tire flora ms

WebJul 20, 2015 · Heterostyly and dioecy are the best-known sexual polymorphism of this type, with heterostylous populations usually composed of two (distyly) or three (tristyly) style morphs , and dioecious populations composed of female and male plants . Disassortative mating in sexually polymorphic populations results in negative frequency-dependent … Webin heterostylous plant populations. (a) Typical tristyly, in which heteromorphic incompatibility only allows mating between stigmas and anthers of equivalent height, resulting in symmetrical disassortative mating, as indicated by the arrows. (b) Tristyly with imperfect reciprocity. The diagram illustrates the predicted asymmetrical mating WebHeterostyly is reported from approximately 25 angiosperm families and has usually been viewed as a floral device that promotes outcrossing, hence reducing the harmful effects of close inbreeding in plant populations.
