MutMap and KASP analyses revealed that the BrGGL7 gene is responsible for the male-sterile trait of ftms1 in Chinese cabbage, with functional verification in Arabidopsis. The application of a male-sterile line is an ideal approach of hybrid seed production in Chinese cabbage. In this study, we obtained a male-sterile mutant (ftms1) from the double haploid line 'FT' using ethyl methane sulfonate (EMS) mutagenesis. The mutant was completely sterile due to abnormal enlargement and vacuolization of the tapetum cells. A single recessive nuclear gene was found to control male sterility in the mutant, while MutMap and KASP analyses identified BraA05g022470.3C (BrGGL7), which encodes a GDSL esterase / lipase, as the candidate mutant gene. A single nucleotide substitution from C to T occurred within the domain of BrGGL7 in ftms1, resulting in premature translation termination in the fourth exon. Meanwhile, qRT-PCR analysis indicated that BrGGL7 was prominently expressed in the anothers, and expression was greater in the wild-type 'FT' than ftms1. Genetic complementation of the orthologous Arabidopsis ggl7 mutant further confirmed the role of BrGGL7 in pollen development. These findings suggest that BrGGL7 plays a fundamental role in pollen formation, providing important insight into the molecular mechanisms underlying male sterility in Chinese cabbage.
