Analysis of Expression Profile of Over-expressed Brassinolide Synthase DET2 in Poplar

We overexpressed the brassinolide synthase DET2 in 84K poplar and obtained an overexpression material.It was found that the brassinolide content of the overexpression material increased significantly.And it was found that the plant height, diameter, and number of internodes of the overexpression material increased significantly.However,the mechanism of this phenotype is unknown.We collected two-month-old DET2 overexpression material and 84K wild-type material in three parts, apex,cambium,and xylem,and conducted high-throughput sequencing.The sequencing results were mined, and the difference genes that were significantly changed in the DET2 overexpression material and the 84K wild-type material were found.Find out how the increase in brassinolide content promotes the development of wood. Overall design: The differentially expressed genes between two-month-old DET2-OE and wild type were detected.
