Transcriptome reorganization during seasonal wood development in Pinus radiata. Pinus radiata

Seasonal wood development results in two distinct wood types: earlywood (EW) and latewood (LW), which is the major cause of wood qaulity variation. We investigate transcriptome reorganization during seasonal wood development in radiata pine using a newly developed 18k cDNA microarrays. Overall design: Three sampling trees each at juvenile (5 yrs), transition (9 yrs) and mature (14 yrs) ages (based on the wood rings at breast height) were selected from a plantation forest of radiata pine at Bondo, NSW , Australia (35º 16' 44.04 S, 148º 26' 54.66 E). The sampling trees at juvenile and mature ages were grown within 50 m distance and under similar environment. Two sampling trees at rotation age (30 yrs) were chosen at Yarralumla, ACT, Australia (35° 18' 27'' S, 149° 7' 27.9'' E).
