Male Sterility in Vegetable Crop: A Mini Review

Shubham Singh, Abhilash Singh

Abstract


Male sterility is a cost-effective and efficient method of facilitating the development of hybrid seeds in a variety of vegetable crops. The development of new genomic tools, molecular markers, and sequencing technology has aided in the mapping and introduction of new male sterility in various vegetable backgrounds. For the development of cytoplasmic male sterility (CMS) and genic male sterility (GMS), male sterility is produced by interactions between mitochondrial genes and nuclear genes, or by nuclear genes alone. CMS and GMS facilitate hybrid seed production in several vegetable crops. In CMS, layers of interaction between mitochondrial and nuclear genes control its male specificity, occurrence and restoration of fertility. Environment-sensitive GMS (EGMS) mutants are controlled by non-coding RNAs and can revert to fertility under different growth conditions, making them useful breeding materials in the hybrid seed industry. Despite the fact that a great deal of study has been done, we still know very little about the biochemical and molecular basis of male sterility system inheritance in many vegetable crops. The genetical, biochemical, and molecular underpinnings of male sterility expression in several vegetable crops, as well as generic models of male sterility and fertility restoration, have been described, and the evolutionary importance of these reproductive systems examined
