Pollen-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 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 ...
متن کاملSpecies specificity in pollen-pistil interactions.
For pollination to succeed, pollen must carry sperm through a variety of different floral tissues to access the ovules within the pistil. The pistil provides everything the pollen requires for success in this endeavor including distinct guidance cues and essential nutrients that allow the pollen tube to traverse enormous distances along a complex path to the unfertilized ovule. Although the pis...
متن کاملPeptide signaling in pollen-pistil interactions.
Plant fertilization is achieved through the involvement of various pollen-pistil interactions. Self-/non-self-recognition in pollination is important to avoid inbreeding, and directional and sustainable control of pollen tube growth is critical for the pollen tube to deliver male germ cells. Recently, various secreted peptides (polypeptides) have been reported to be involved in cell-cell commun...
