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.
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 ...
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.
The brassica MIP-MOD gene encodes a functional water channel that is expressed in the stigma epidermis. Plant Mol Biol. 2001 Jan;45(1):51–62. doi: 10.1023/a:1006428007826. [ DOI ] [ PubMed ] [ Google Scholar ]

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 angiosperm stigma is an efficient structure with both morphological and physiological adaptations that enable pollen capture, hydration and germination. The stigma surface may play a vital part in controlling interspecific hybridization and in regulating compatibility relationships within species.
