Abstract:

Gibberellin pathway is an important pathway in plant flowering regulation.In order to understand the role of gibberellin pathway related genes in the regulation of radish flowering. The structure,physicochemical properties,chromosome distribution,promoter cis-elements and tissue-specific expression of gibberellin biosynthesis and signal transduction related genes in radish were analyzed by bioinformatics.The expression levels of these genes in radish varieties with different florescence were detected by Real-time fluorescence quantitative PCR(qPCR).The results showed there were 46 genes related to gibberellin biosynthesis and signal transduction in radish genome,among them,the gene numbers of CPS,KS,KO,KAO,GA20OX,GA3OX,GA2OX,GAI,RGA,RGL,GID1 and SKP2 were 2,1,2,2,9,5,12,1,1,4,3 and 4,respectively.They were unevenly distributed on 9 chromosomes,molecular weight of their coding proteins were 21.32—127.80 ku,and the isoelectric points of the proteins were from 4.72 to 9.04.The analysis of gene structure and conserved domain showed that the number of exons of these 46 genes ranged from 1 to 21,and some conserved motifs were shared by most genes.Promoter cis-elements analysis showed that the promoters of these 46 genes contained cis-elements related to light,gibberellin,auxin,ABA,SA,low temperature,drought,etc.Using radish gene expression database analysis,it was found that the expression levels of these 46 genes were different in different tissues and at different developmental stages;qPCR detection showed that there were significant differences in the expression of these genes between early flowering material Xinlimei and late flowering material wild radish,suggesting that they may be closely related to the reproductive growth of radish.
