摘要: Suppression subtractive hybridization method was used to profile gene changes in the latex between selfrooting juvenile clones (JCs) and donor clones (DCs) to better understand the molecular mechanism underlying the differences between these clones. 176 differentially expressed genes were identified, 95 of which were upregulated and 81 with reduced self-rooting JCs. These genes were classified as stress/defense response, rubber biosynthesis, metabolism and energy, protein metabolism, signal transduction transcription, and post-transcription. Systematic analyses of the differentially expressed genes between self-rooting JCs and DCs suggest that rubber biosynthesis, production, and scavenging of reactive oxygen species may have significant functions in high-yielding self-rooting JCs. This result contributes to better understanding on the molecular mechanism underlying the difference between self-rooting JCs and DCs.
