Pre-meiotic anther development
WebDefects in pre-meiotic anthers that alter cellular composition or function typically result in male-sterility. Given the ease of identifying male-sterile mutants, dozens of genes with key … WebResults showed that the anther wall was of the basic type and consisted of an epidermis, endothecium, middle layers, and tapetum. The tapetum was of the glandular type. Cytokinesis during meiosis of the microspore mother cell was of the simultane-ous type, tetrads were tetrahedral, pollen grains were the 2-cell type, and development of the em-
