Abstract Tapping panel dryness (TPD) is a serious threat to natural rubber yields from trees, but the molecular mechanisms underlying TPD remain poorly understood. To identify TPD-related genes and reveal these mechanisms, we sequenced compared transcriptomes of bark between healthy trees. In total, 57,760 assembled were obtained analyzed in details. contrast 5652 2485 up- or downregulated, respectively, The significantly enriched eight GO terms five KEGG pathways closely associated with ROS metabolism, programmed cell death biosynthesis. Our results suggest that tree complex process involving many genes. observed lower yield trees might result isopentenyl diphosphate (IPP) available for biosynthesis downregulation post-IPP steps pathway. not only extend our understanding events involved also will be useful developing effective measures control
