  4. 25 sty 2023 · For the analysis of S-nitrosation in stigmas before and after pollination, 200 stigmas (approximately 0.1 g) from A. thaliana plants expressing pAtFER::AtFER–GFP or pAtFER::GFP–AtRBOHD ...

  5. 28 cze 2008 · Summary. 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.

  6. 1 lip 2013 · Introduction. Pollenstigma interaction is crucial for the reproductive success of flowering plants. Upon pollination, a cell to cell interaction occurs between the stigma papillae and pollen grains, leading to an exchange of chemical signals between the two.

  7. 20 maj 2023 · Polypeptides play irreplaceable roles in cell–cell communication; anther development and pollen-stigma interaction are essential for sex reproduction; various peptide signaling involved in tapetum formation, pollen hydration, pollen germination and pollen tube growth. Abstract.
