Genome-Wide Identification and Expression Analysis of Family in Potato ( L.).

Transcription factors containing a CCCH structure (C3H) play important roles in plant growth and development, and their stress response, but research on the gene family in potato has not been reported yet. In this study, we used bioinformatics to identify 50 genes in potato and named them to according to their location on chromosomes, and we analyzed their physical and chemical properties, chromosome location, phylogenetic relationship, gene structure, collinearity relationship, and cis-regulatory element. The gene expression pattern analysis showed that many genes are involved in potato growth and development, and their response to diverse environmental stresses. Furthermore, RT-qPCR data showed that the expression of many genes was induced by high temperatures, indicating that genes may play important roles in potato response to heat stress. In addition, Some genes were predominantly expressed in the stolon and developing tubers, suggesting that these genes may be involved in the regulation of tuber development. Together, these results provide new information on genes and will be helpful for further revealing the function of genes in the heat stress response and tuber development in potato.
