11 cze 2004 · Defines stigmas as uniquely water-permeant sites on the plant; proteins and lipids are involved in adhesion, hydration, and germination; dry stigmas are pollen compatibility sites, with selective support of pollen hydration and germination, whereas wet stigmas often are covered in exudates from apoptotic cells and block inappropriate ...
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.
18 kwi 2024 · Through genetic and molecular analyses of interspecific stigma–pollen interactions, the authors show that Brassicaceae plants use an integrated pollen discrimination system and a shared pollen...
23 paź 2024 · This is a basic visualization of our empirical RCF tensor, with 691 nodes (16 plant species and 675 animal/fungus taxa) interacting via six functions: pollination, herbivory, seed dispersal ...
Pollen and stigma structure and function: the role of diversity in pollination. Plant Cell. 2004;16 Suppl (Suppl):S84-97. doi: 10.1105/tpc.015800. Epub 2004 Apr 9. Authors. Anna F Edlund 1 , Robert Swanson, Daphne Preuss. Affiliation.
1 lip 2018 · In the Ficus-fig wasp mutualism, stigmata have an additional, almost unknown, function by representing a physical interface for both plant and wasp reproduction. We used light and electron microscopy to compare the detailed morphology of the stigmata of nine Ficus species of different sections and with different pollination modes and sexual ...
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.
