Function of elongator complex protein 2 against Sclerotinia sclerotiorum of rapeseed
摘要
Abstract
Rapeseed production is severely restricted by Sclerotinia disease.Elongator complex protein(ELP)is a 6-subunit complex that interacts with RNA polymerase Ⅱ,involved in plant defense response.To deeply under-stand its gene function,we constructed vectors on overexpressed-BnA06.ELP2 and knockout-BnA06.ELP2(by gene editing)using homologous recombination method,and then investigated their transgenic plants.Disease resis-tance experiments showed that BnA06.ELP2 overexpression plants exhibited better resistance compared to wild-type,while gene edited BnA06.ELP2 plants led to a decrease of resistance.Further RT-qPCR analysis indicated that BnA06.ELP2 could regulate transcription of catalase BnCAT1 and BnCAT2(marker genes of JA/ET pathway),jasmonate synthesis related genes BnLOX2 and BnOPR1,and BnPDF1.These results indicated that BnA06.ELP2 function in rapeseed is involved in defense response against Sclerotinia sclerotiorum infection.关键词
