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.
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 ]

The World Health Organization (WHO) estimates that as many as 80% of the world's more than six billion people rely primarily on animal and plant-based medicines . Traditional human populations have a broad natural pharmacopoeia consisting of wild plant and animal species.
26 lis 2022 · Drosophila is a powerful model to decipher the molecular mechanism of the host’s innate immune response to PAMPs and DAMPs and to screen the pharmacological effects of medicinal plant extracts and their derived compounds that may function in the immune response.
1 sty 2007 · Abstract. Reactive oxygen species (ROS) and reactive nitrogen species, particularly NO, are key components of diverse signaling networks in animals and plants. We have recently shown that epidermal cells of stigmas from a range of different angiosperms accumulate relatively large amounts of ROS, principally H 2 O 2, whereas pollen produces NO.
5 paź 2021 · The main function of elongated cells of the stigma (called stigmatic papillae) is to trap pollen grains, thus mediating the fertilization of ovules enclosed within the fruit.
