马铃薯GH3基因家族成员的鉴定及表达分析
Identification and Expression Analysis of GH3 Gene Family Members in Potato(Solanum tuberosum)
摘要
Abstract
The expression of Gretchen Hagen 3(GH3)genes plays an important role in plant growth and development and response to biotic stresses.In this study,the potato(Solanum tuberosum)cultivar'Qingshu 9'as the materical for identification and bioinformatics analysis of GH3 family members,and their expression patterns were analysed in potato different tissues and in response to salicylic acid(SA),Methyl jasmonate(MeJA)and gibberellin A3(GA3)and Phytophthora infestans stresses.Promoter cis-acting element analyses showed that StGH3 family members contained a large number of hormone-related acting elements,speculated that it had potential function in response to biotic and abiotic stresses.Tissue specific analysis showed that StGH3.4 and StGH3.5 genes were highly expressed in roots,StGH3.8 was highly expressed in stems,and StGH3.10 and StGH3.16 were highly expressed in leaves.StGH3 family members were regulated under SA,MeJA,GA3 and P.infestans stress treatments and showed different expression patterns.The StGH3.1,StGH3.5,and StGH3.8 genes responded more strongly to the P.infestans treatment.This study provides a scientific basis for subsequent studies of StGH3 genes function.关键词
