Genome-wide transcriptional profiling reveals molecular signatures of secondary xylem differentiation in Populus tomentosa

X. H. Yang, Li, X. G., Li, B. L., and Zhang, D. Q., Genome-wide transcriptional profiling reveals molecular signatures of secondary xylem differentiation in Populus tomentosa, vol. 13, pp. 9489-9504, 2014.

Wood formation occurs via cell division, primary cell wall and secondary wall formation, and programmed cell death in the vascular cambium. Transcriptional profiling of secondary xylem differentiation is essential for understanding the molecular mechanisms underlying wood formation. Differential gene expression in secondary xylem differentiation of Populus has been previously investigated using cDNA microarray analysis. However, little is known about the molecular mechanisms from a genome-wide perspective.
