Transciptome analysis reveals flavonoid biosynthesis regulation and simple sequence repeats in yam (Dioscorea alata L.) tubers.


ABSTRACT: BACKGROUND:Yam (Dioscorea alata L.) is an important tuber crop and purple pigmented elite cultivar has recently become popular because of associated health benefits. Identifying candidate genes responsible for flavonoid biosynthesis pathway (FBP) will facilitate understanding the molecular mechanism of controlling pigment formation in yam tubers. Here, we used Illumina sequencing to characterize the transcriptome of tubers from elite purple-flesh cultivar (DP) and conventional white-flesh cultivar (DW) of yam. In this process, we also designed high quality molecular markers to assist molecular breeding for tuber trait improvement. RESULTS:A total of 125,123 unigenes were identified from the DP and DW cDNA libraries, of which about 49.5% (60,020 unigenes) were annotated by BLASTX analysis using the publicly available protein database. These unigenes were further annotated functionally and subject to biochemical pathway analysis. 511 genes were identified to be more than 2-fold (FDR?
