Brassica napus (B. napus, AACC, 2n=38) is one of the most important global oil crops. But, the fundamental research of B. napus is relatively backward , in particuluar genes that regulating various agronomic traits have not been clearly understood, severely limiting breeding process.

Expression database can facilitate the identification of gene functions,which is greatly needed in rapeseed. Here we present a highly comprehensive temporal-resolution study of developmental transcriptomes by using data from eight different tissues covering ZS11 ( Zhong shuang 11 ) 3 distinct developmental stages during its life cycle, including cotyledon,root,stem peel,leaf,bud,flower,silique,silique wall and seed. Especially ,there exist 26 and 23 time points in seed and silique wall respectively and 24 leaf developmental time points , with 2 day intervals. Based on analysis of these transcriptome data , we develop BnTIR (http://yanglab.hzau.edu.cn/BnTIR) , and provide function modules like eFP, JBrower, Blast , co-expression,Gene Index conversion and other features. Besides, in our data page some extensive linkouts can be clicked to other B. napus resources.
