Identification of candidate genes affecting juvenile wood stiffness in Pinus radiata

ABSTRACT: Wood stiffness is the most important wood quality trait of forest trees for structural timber production. We investigated genes differentially transcribed in radiate pine trees with distinct wood stiffness using bulked segregant analysis (BSA) and cDNA microarrays. Transcript accumulation in earlywood (EW) and latewood (LW) of high (HS) and low stiffness (LS) trees in two progeny trials was compared. Radiata pine trees used for microarray experiment were selected from two progeny trials planted at Flynn and Kromelite, Australia. Based on the IML-based MOE measurement, five families with highest and lowest MOE each were selected from each trial, which represented two segregant populations with contrasting wood stiffness. Two individuals from each selected family were further sampled. Develo
