Pollen lands on the stigma, where it hydrates, germinates, and extends a tube that enters the transmitting tract (rr). The tube emerges onto the septum (S), grows up the funiculus (f), and enters the micropyle opening of the ovule (O), where it fertilizes the egg and central cell.
1 cze 2004 · 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 involved in sexual interactions, remain among the most rapidly evolving and diverse characteristics known.
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 2007 · Recent years, studies indicated that stigma closure may increase pollen capture and receipt, improve pollen germination and pollen tube growth, and prevent intra-floral selfing.
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.
1 lut 2018 · Abstract. The stigma plays several roles such as pollen hydration and selection, and pollen tube nutrition. In the Ficus-fig wasp mutualism, stigmata have an additional, almost unknown,...
In this review, we (a) discuss the hypotheses proposed for the adap-tive value of TSS, (b) examine the phylogenetic dis-tribution of TSS in angiosperms, and (c) investigate associations between TSS and plant reproductive traits that we predicted to be relevant to the evolution of the phenomenon.
