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.
27 sty 2020 · We conceptually summarize how the study of pollen on stigmas of spent flowers can reflect key drivers and functional aspects of the plant–pollinator interaction (e.g. competition, facilitation or commensalism).
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 ]
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.
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 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.
18 kwi 2024 · Here we show that Stigma UI3.1, the genetically identified stigma determinant of UI in Arabidopsis lyrata × Arabidopsis arenosa crosses, encodes the S-locus-related glycoprotein 1 (SLR1).
