IDENTIFICATION OF THE CELL WALL SYNTHESIS GENES IN BETULA PENDULA

Abstract

This study aims to provide information on Betula pendulacell wall synthesis genes regarding their potential physiological roles and the molecular mechanism associated. Here we identified 46 gene models in 7 gene families that encode cellulose synthase and related enzymes of B. pendula, and the transcript abundance of these genes in xylem, root, leaf, and flower tissues also be determined. Based on these RNA-seq data, we have identified 8 genes that most likely participate in cell wall synthesis, which include 3 cellulose synthase genes and 5cellulose synthase-like genes. In parallel, a gene co-expression network was also constructed based on transcriptome sequencing. These analyses will help decipher the genetic information of B.pendulacell wall synthesis genes and alter its wood structureon the cellular level.
