Fig. 8From: Comparative transcriptome analyses define genes and gene modules differing between two Populus genotypes with contrasting stem growth ratesA model for the regulation of vascular tissue development by PeuBELL15. During the growth, PeuBELL15 is expressed in the stem and up-regulates the expression levels of cellulose biosynthesis and lignin biosynthesis-relevant genes to supply compositions for secondary cell wall biosynthesis in vascular tissues. Additionally, expression abundances of other cell wall regulator genes such as EXPB (β-expansin) and FLA (fasciclin-like arabinogalactan protein) are increased by PeuBELL15 to promote the cell expansion of vascular tissuesBack to article page
