摘要: Latex exploitation enhances latex regeneration in rubber trees. The exploitation-caused flow lasts from 10 min to a few hours, which is convenient for exploring the transcript profiling of metabolism-related genes at different stages flow. In present study, expression pattern 62 involved water transportation, carbohydrate metabolism, natural biosynthesis, hormone signaling, ROS generation and scavenging, coagulum across three between tree clones CATAS7-33-97 CATAS8-79 were comparatively analyzed by quantitative real-time PCR. two show differences have duration results showed that levels 38 significantly higher than during regeneration, while 45 had notably level Together with activation MEP pathway jasmonate latex, HbPIP1;3, HbPIP1;4, HbSUT3, HbSus3, HbHMGS1-2, HbMK should contribute high ability. up-regulation ethylene signaling Hb44KD down-regulation coagulation-related might its longer duration. This study provides some cues revealing regulation metabolism
