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)?
1 paź 1993 · Figure 1 shows that anther development can be divided into two general phases. During phase 1, the morphology of the anther is established, cell and tissue differentiation occur, and microspore mother cells undergo meiosis.
Figure 1 shows that anther development can be divided into two general phases. During phase 1, the morphology of the anther is established, cell and tissue differentiation occur, and microspore mother cells undergo meiosis. At the end of phase 1, the anther contains most of its specialized cells and tissues,
Anther development in Arabidopsis has been divided into 15 stages, which commence from division of a single archesporial cell; defined cell types and adaxial–abaxial polarity are established, resulting in the formation of the mature microsporangia (Scott et al. 2004).
Anther development is a complex process, which requires timely formation and communication between the multiple somatic anther cell layers (the epidermis, endo-thecium, middle layer and tapetum) and the developing pollen.
27 sie 2015 · Pollen development comprises three major stages: (i) micro- sporogenesis (differentiation of the sporogenous cells and meiosis); (ii) post-meiotic development of microspores; and
Anther and pollen development have been widely studied in Arabidopsis (Wilson and Zhang 2009); it is a complex and important process that leads to the release of viable pollen and plant fertilization.
