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 · Summary. 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.
1 lip 2013 · Pollen–stigma interaction is crucial for the reproductive success of flowering plants. Upon pollination, a cell to cell interaction occurs between the stigma papillae and pollen grains, leading to an exchange of chemical signals between the two.

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.
This chapter aims to show the range of morphological variation in stigma types found throughout the angiosperms, to enable classification of stigmata into the major recognized groups, and to indicate the relationship between structure and function.
