Novel genes in Sitka spruce associated with wood density identified from global transcriptomic analysis

ABSTRACT: The current study uses a transcriptomic approach to identify genes associated with differences in wood density, that are likely to be of value as candidate genes in Sitka breeding programmes for improved wood density. Following extensive wood density analysis from a Sitka spruce (Picea sitchensis (Bong) Carr.) field grown clonal trial, three detailed microarray studies were conducted to compare the transcriptome of cambial tissue from contrasting clonal lines with high and low wood density. Twenty five genes exhibited differential expression, reaching as high as 50 fold, in at least two of the three microarray experiments and this was verified using real-time PCR. Identified genes functioned in cell wall synthesis, transcriptional regulation and plant pathogen defence, amongst others. Thes
