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.
24 gru 2021 · Stigma is a part of the female reproductive structure of the flower. It comprises the pistil, a part of the gynoecium or female reproductive organ of a plant, together with two other structures, the style, and ovary. Stigma is a specially adapted portion of the pistil modified for pollen reception. Stigma 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.
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.
29 sty 2024 · Rapid touch-sensitive stigma closure is a novel plant reproductive trait found in hundreds of Lamiales species. The origins, mechanisms, and functions of stigma closure remain poorly...
11 cze 2004 · Whether the pollen is transported by the wind or by animal pollinators, after landing on the stigma the pollen grain hydrates and germinates a tube. This tube then penetrates the specialized tissues of the pistil, growing into the stigma and the style to reach the ovules in the ovary.
26 gru 2022 · In this review, we examine its occurrence in the angiosperm phylogeny and investigate associations between plant reproductive traits and TSS. Prominent hypotheses regarding the evolution of TSS invoke the adaptive functions of outcrossing, pollination efficiency, and pollen germination.
