Stigma can play an active role in pollen discrimination and some self-incompatibility reactions, that reject pollen from the same or genetically similar plants, involve interaction between the stigma and the surface of the pollen grain.
11 cze 2004 · In this review, we (1) survey recent discoveries of pollen and stigma functions both before and after they make contact, and (2) address the great diversity in pollen and stigma structures across taxa, focusing on how they accomplish key tasks in pollination.
Pollen and stigma structure and function: the role of diversity in pollination. Anna F Edlund 1 Howard Hughes Medical Institute, Molecular Genetics and Cell Biology Department, University of Chicago, Chicago, Illinois 60637, USA.
28 maj 2018 · Stigma receptivity is a key prerequisite for successful pollination and seed set in flowering plants. From a plant breeder’s perspective, extending the length of time that the stigma can...
The angiosperm stigma is an efficient structure with both morphological and physiological adaptations that enable pollen capture, hydration and germination. The stigma surface may play a vital part in controlling interspecific hybridization and in regulating compatibility relationships within species. The structural and physiological features ...
8 cze 2018 · The stigmas of flowering plants selectively recognize pollen from the same species in part through biochemical interactions.
