Self Rejection during Pollen-pistil Interactions
Plants being sessile by nature have developed sophisticated mechanisms to assist in their selection of mating partners. During a compatible pollination event, pollen grains that have landed on the stigmatic surface at the top of the pistil will adhere to the stigmatic cells, hydrate, germinate and form pollen tubes. The actively growing pollen tubes are often capable of penetrating the stigmati...
متن کاملPollen-Pistil Interactions and Their Role in Mate Selection.
As a group, the flowering plants have remarkably diverse modes of reproduction that run the gamut from clonal propagation to obligate outcrossing. Articles in this volume focus on sexual reproduction, and there is great diversity even within this slice of the reproduction spectrum. Like all diverse systems, reproductive characters are the end results of molecular and genetic mechanisms that gen...
متن کاملPollen tube localization implies a role in pollen-pistil interactions for the tomato receptor-like protein kinases LePRK1 and LePRK2.
We screened for pollen-specific kinase genes, which are potential signal transduction components of pollen-pistil interactions, and isolated two structurally related receptor-like kinases (RLKs) from tomato, LePRK1 and LePRK2. These kinases are similar to a pollen-expressed RLK from petunia, but they are expressed later during pollen development than is the petunia RLK. The abundance of LePRK2 ...
متن کاملSelf-incompatibility and other pollen-pistil interactions.
Self-incompatibility allows plants to recognize and reject pollen from the same plant, thereby reducing inbreeding. Although in most cases self-incompatibility is controlled by a single genetic locus, recent results show that surprisingly complex signal transduction pathways and many players are involved in pollen recognition and rejection.
متن کاملPollen-pistil interactions in compatible pollination.
Plant sexual reproduction depends on highly specific interactions between pollen and pistil, the male gametophyte and the female reproductive organ, respectively (1, 2). The pistil is composed of three major structural parts: the stigma, the style, and the ovary. The stigma has a pollen-receptive surface and several underlying secretory cell layers. The style connects the stigma to the basally ...
