Cytoplasmic genic male sterility (CGMS) is a system that uses the maternal line for hybrid production, ensuring no obscurity of F1 seed purity and reducing cost production. Identification gene important plant improvement classification when using molecular marker-assisted selection (MAS) method. This study aimed to produce new (A-line) its maintainer (B-line) by transferring male-sterile from a...
Aberrant Meiotic Prophase I Leads to Genic Male Sterility in the Novel TE5A Mutant of Brassica napus
Genic male sterility (GMS) has already been extensively utilized for hybrid rapeseed production. TE5A is a novel thermo-sensitive dominant GMS line in Brassica napus, however, its mechanisms of GMS remain largely unclear. Histological and Transmission electron microscopy (TEM) analyses of anthers showed that the male gamete development of TE5A was arrested at meiosis prophase I. EdU uptake of S...
For normal sexual reproductive development, coordination must occur between both male and female organ ontogeny. An abnormality at any point in this process may lead to sterility. Classification of sterility can be divided into heritable and nonheritable sterility. Numerous schemes for mechanisms controlled by nuclear genes (genic male sterility) have been devised to identify the timing and loc...
