22 wrz 2022 · What is the developmental timeline for a species: days from anther inception to the start of meiosis, duration of meiosis, and postmeiotic development to pollen shed? Does the endothecium store starch (KI/I 2 stain) and contain chloroplasts (red fluorescent signal)?
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 · Despite similarities in the general pathway of pollen development, four types of anther wall development have been described: Basic (type I), dicotyledonous (type II), monocotyledonous (type III) and reduced (type IV) (Davis 1996).
An overview of the structure of a typical angiosperm anther and the microsporangia within it.
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.
11 lip 2022 · Investigating gene expression profiles throughout the entire span of anther development, and in particular identifying genes with phase‐specific expression, is vital to exploring the mechanisms by which anther development is regulated and discovering key genes potentially useful for hybrid breeding.
The immature anther (top) contains four microsporangia, or pollen sacs. Each microsporangium contains hundreds of microspore mother cells that will each give rise to four pollen grains. The tapetum supports the development and maturation of the pollen grains.
