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.
1 kwi 2022 · The following sections discuss research around consumers’ most common values and beliefs to adopt a vegan lifestyle, the potential mediating effect of social stigma as discussed in vegan literature, and how these variables relate and contribute to behaviour, resulting in a conceptual framework.
25 sty 2023 · A signalling mechanism ensuring intraspecies and interspecies reproductive barriers in flowering plants is uncovered.
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.
28 maj 2018 · New evidence reveals how two transcription factors play a pivotal role in controlling stigma lifespan by regulating developmental programmed cell death in this tissue to terminate pollen...
Here we review our current understanding of the cellular and molecular interactions that mediate the earliest of these interactions between the pollen and the pistil that occur on or within the stigma – the ‘pollen–stigma interaction’.
