摘要： Plant filamentation temperature-sensitive H (FtsH) proteins are ATP-dependent zinc proteases that play an important role in regulating abiotic stress adaptions. Here we explore their potential role in abiotic stress tolerance in alfalfa, an important legume crop. Genomic analysis revealed seventeen MsFtsH genes in five clusters, which generally featured conserved domains and gene structures. Furthermore, the expression of MsFtsHs was found to be tightly associated with abiotic stresses, including osmotic, salt and oxidative stress. In addition, numerous stress responsive cis-elements, including those related to ABA, auxin, and salicylic acid, were identified in their promoter regions. Moreover, MsFtsH8 overexpression was shown to confer tolerance to salt and oxidative stress which was associated with reduced levels of reactive oxygen species, and enhanced expression and activity of antioxidant enzymes. Our results highlight MsFtsHs as key factors in abiotic stress tolerance, and show their potential usefulness for breeding alfalfa and other crops with improved yield and stress tolerance.
