Do transcriptome profiling of radiata pine branches reveals new insights into reaction wood formation with implications in plant gravitropism?
The first comprehensive investigation of tracheid characteristics, wood properties and gene transcription in branches of a conifer species revealed more accurate and new insights into reaction wood formation in response to gravity stress. The identified differentially transcribed genes with diverse functions conferred or implicated drastic CW and OW variation observed in radiata pine branches. These genes are excellent candidates for further researches on the molecular mechanisms of reaction wood formation with a view to plant gravitropism.
No role of radiotherapy or indomethacin was detected in the prevention of heterotopic ossification.
