Abstract: The CRM(Chloroplast RNA splicing and ribosome maturation) genes involve in the splicing of genes containing group Ⅱ introns in mitochondria and chloroplast genome in plants. In the present study, gene number, conserved motif, isoelectric point of amino acids, molecular evolution, and expression pattern of CRM family of Brassica rapa(AA,2n=20) were well analyzed based on the bioinformatic methods. A total of 22 genes belonging to CRM gene family were identified in the B. rapa genome. These genes could be divided into three subgroups, and distributed on all the chromosomes of B. rapa except chromosome A10. The coding sequences of CRM genes ranged from 657 bp to 5 909 bp, and the isoelectric point of amino acids of these genes ranged from 4.42 to 9.89. The CRM genes in B. rapa showed specific expression in different tissues and response to different stresses, and some CRM genes were actively transcribed in leaves and stems. After dealt with Flg22 and Ps stress which can be used to simulate biotic stresses, some CRM genes significantly down-regulated, indicating these genes likely responded to the biotic stresses.

Key words: Brassica rapa, CRM gene family, bioinformatics, biotic stress
