General Information

2.3.1.15 evolution phylogenetic analysis of MS33 Zea mays
2.3.1.15 malfunction the enzyme mutant plants show substantial reduction in wax and cutin in ms33 anthers compared to wild-type. The maize male-sterile mutant shrinking anther 1 (sa1), which is allelic to the classic mutant male sterile 33 (ms33), displays defective anther cuticle development and premature microspore degradation. Male-sterile mutant sa1 phenotype compared to wild-type, overview. Female fertility is not affected in sa1, but the microspores of sa1 appear irregular, the anther layers appear collapsed, and the microspores are defective. At the mature pollen grain stage, in wild-type anthers, many pollen grains are present in the anther locule, whereas in sa1 anthers, no pollen grains are observed, and only some residual debris remain. Comparison of cutin and wax compositions of wild-type and mutant enzymes Zea mays
2.3.1.15 physiological function enzyme MS33 (SA1) may play an essential role in anther cuticle and pollen grain/microspore development by affecting lipid polyester biosynthesis in maize. MS33 affects the expression of genes involved in wax and cutin biosynthesis Zea mays
