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.
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 ]
In our study, measuring connectance helps us assess how human activities, which alter habitat structure, floral resource availability, and pollinator abundance, can impact the density and efficiency of interactions within the plant-pollinator networks (Tavares-Brancher et al., 2024).
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.
1 cze 2004 · Pollen and Stigma Structure and Function: The Role of Diversity in Pollination. The ornate surfaces of male and female reproductive cells in flowering plants have long attracted attention for their variety and evolutionary significance. These structures, and the molecules….
