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.
28 cze 2008 · Siphonogamy, the delivery of nonmotile sperm to the egg via a pollen tube, was a key innovation that allowed flowering plants (angiosperms) to carry out sexual reproduction on land without the need for water. This process begins with a pollen grain (male gametophyte) alighting on and adhering to the stigma of a flower.
20 maj 2023 · In this review, we mainly summarized the role of various peptide/RLK signaling in anther development and in pollen-stigma interactions that have broadened our knowledge about sexual reproduction in flowering plants.

1 sty 2017 · Animal-pollinated plants display a multiplicity of structural adaptations that function to promote effective cross-pollen dispersal and reduce pollen wastage, especially on incompatible stigmas.
The production of extracellular lipid rich secretions on stigma surface is initiated at the staminate stage of stigma development and it increases at the receptive stage due to enhanced availability of elaioplasts and endoplasmic reticulum network in the basal region of the papillae.
