22 wrz 2022 · One haploid cell within the embryo sac differentiates as the egg. Anthers support the maturation of germinal cells that undergo meiosis to form haploid microspores; after two mitotic divisions, the microgametophyte. This matures into pollen, containing two sperm cells and a vegetative cell.
29 lis 2022 · After signal perception or self-organization, germinal cells are specified from Layer 2-derived cells, and these secrete a protein ligand that triggers somatic differentiation of their neighbors. Historically, recovery of male-sterile mutants has been the starting point for studying anther biology.
26 cze 2021 · We summarise new findings that illustrate the complexities of anther development and evaluate how they challenge established models of anther form and function, and how they may help to deliver future sustainable crop yields.
27 sie 2015 · The sporophytic anther tissues, in particular the tapetum cell layer, play an essential part in this developmental process both in the regulation and coordination of development, but also in providing materials for pollen wall formation.
17 lis 2023 · Here, the first single-cell transcriptome atlas and chromatin accessibility survey in cotton anther are established, depicting the specific expression and epigenetic landscape of each type of cell in anthers.
22 wrz 2022 · We summarise new findings that illustrate the complexities of anther development and evaluate how they challenge established models of anther form and function, and how they may help to...
11 lip 2022 · Next‐generation sequencing of the four key maize anther development phases based on anther length identified phase‐specific marker genes, providing a valuable resource for exploring key phase‐specific genes that play essential roles during anther development.
