摘要
Adzuki bean(Vigna angularis) is one of the most important legume crops in Asia due to its nutritious protein and starch contents,as well as its useful potential for cropping structure adjustment in China.In spite of its economic importance,gene expression analysis system for gene function verification of adzuki bean is still absent.Therefore,reference genes for gene expression analysis based on the quantitative real time PCR(qRT-PCR) were screened in current study.A total of nine general housekeeping genes,including ACT,Fbox,ZMPP,GAPDH,EF,PP2 A,UBC,UBN and PTB were evaluated for their expression stability by qRT-PCR in four adzuki bean cultivars,three different tissues,four abiotic stress and a biotic stress.The best group of candidates as reference genes were as follows:PP2A and PTB for different cultivars;EF,PP2 A and UBN for different tissues;ACT,UBC and UBN for biotic stress;ACT and ZMPP for waterlogging stress;Fbox,UBC and UBN for salinity-alkalinity stress;and Fbox,ACT and PTB for drought stress.Our results will provide a more accurate and reliable normalization of qRT-PCR data in adzuki bean.
