A MADS-box gene is involved in soybean resistance to multiple Soybean mosaic virus strains
文献摘要：
Soybean mosaic virus(SMV)is a member of the genus Potyvirus that extensively impairs global soybean production.The full-length coding sequence of the MADS-box transcription factor GmCAL was cloned from the SMV-resistant soybean cultivar Kefeng 1.SMV-induced expression analysis indicated that GmCAL responded quickly to SMV-SC8 infection in Kefeng 1 but not in NN1138-2.GmCAL was expressed at high levels in flowers and pods but at lower levels in leaves.The gene was localized to the nucleus by subcellular localization assay.Virus-induced gene silencing did not increase the accumulation of SMV in GmCAL-silenced Kefeng 1 plants(with silencing efficiency～80％)after SC8 inoculation.GmCAL-silencing plants still conferred resistance to SC8 that might be owing to incomplete silencing of genes with lower expression.SMV content decreased significantly in GmCAL-overexpressing NN1138-2 plants after SMV-SC3,SMV-SC7,and SMV-SC8 inoculation in comparison with a vector control,showing that overexpres-sion of GmCAL conferred broad-spectrum resistance to multiple SMV strains.These results confirm that GmCAL,a key regulator but not a specific SC8 resistance gene(Rsc8),is a positive regulatory transcription factor involved in soybean resistance to SMV.
