This study demonstrates for the first time the role of MnGolS2 in biotic stress. It was also found that MnGolS2 may increase resistance to Botrytis cinerea by interacting with other resistance genes.
Galactitol synthetase (GolS) as a key enzyme in the raffinose family oligosaccharides (RFOs) biosynthesis pathway, which is closely related to stress. At present, there are few studies on GolS in biological stress. The expression of MnGolS2 gene in mulberry was increased under Botrytis cinerea infection. The MnGolS2 gene was cloned and ectopically expressed in Arabidopsis. The content of MDA in leaves of transgenic plants was decreased and the content of CAT was increased after inoculation with B. cinerea. In this study, the role of MnGolS2 in biotic stress was demonstrated for the first time. In addition, it was found that MnGolS2 may increase the resistance of B. cinerea by interacting with other resistance genes. This study offers a crucial foundation for further research into the role of the GolS2 gene.
