In soybean, genic male sterility can be utilized as a tool to develop hybrid seed. Several male-sterile, female-fertile mutants have been identified in soybean. The malesterile, female-fertile ms5 mutant was selected after fast neutron irradiation. Male-sterility due to ms5 was associated with the “stay-green” cotyledon color mutation. The cotyledon color trait in soybean is controlled by two l...
Glume-unclosing after anthesis is a widespread phenomenon in hybrid rice and also a maternal hereditary trait. The character of Glume-unclosing in rice male sterile lines also seriously influences germination rate and the commercial quality of hybrid rice seeds. We validated that the type of glume-unclosing after anthesis in the elite rice thermo-sensitive genic male sterile (TGMS) line RGD-7S ...
The pentatricopeptide repeat (PPR) gene family represents one of the largest gene families in higher plants. Accumulating data suggest that PPR proteins play a central and broad role in modulating the expression of organellar genes in plants. Here we report a rice (Oryza sativa) mutant named young seedling albino (ysa) derived from the rice thermo/photoperiod-sensitive genic male-sterile line P...
Hybrid rice breeding offers an important strategy to improve rice production, in which the cultivation of a male sterile line is the key to the success of cross-breeding. CRISPR/Cas9 systems have been widely used in target-site genome editing, whereas their application for crop genetic improvement has been rarely reported. Here, using the CRISPR/Cas9 system, we induced specific mutations in TMS...
The utilization of thermosensitive genic male sterility system (TGMS) has great potential for revolutionizing hybrid rice production in tropical countries through simple, less expensive and efficient seed production technology without any limitation in fertility restoration which have been the hindrance for commercial exploitation of heterosis in rice using cytoplasmic genic male sterility syst...
Two-line hybrid rice production requires environmental genetic male-sterile (EGMS) lines that become sterile in certain conditions. In this study, we aimed to identify the type(s), sterility thresholds, optimum planting date, and efficient seeding density of eight lines, including four developed at University Arkansas, Rice Research Extension Center (RREC) Dale Bumpers National (DBNRRC) both lo...
