Identification of candidate genes affecting juvenile wood density in Pinus radiata

ABSTRACT: Wood density is a foundamental quality trait for structural timber, bioenergy and pulp industries. We investigated genes differentially transcribed in radiate pine juvneile trees with distinct wood density using cDNA microarrays. Radiata pine trees were selected from a progeny trial planted at Flynn, Australia. Based on the gravitical measurement of wood cores, 12 families with highest and lowest density each were selected, representing two groups of trees with contrasting wood density. One individual with higher or lower density were further sampled in each selected family. Developing xylem tissues of selected trees were sampled in autumn (April) when latewood (LW) was formed. The xylem tissues were scraped at breast height with a sharp chisel after the bark was removed. Wood cores of the
