4.2.3.119 down transcript levels are transiently reduced following mechanical wounding or fungal elicitor treatment 653533 4.2.3.119 additional information under a photoperiod of 12 h/12 h (light/dark), the abundance of QH6 transcripts fluctuates in a diurnal pattern that ebbs around 3 h before daybreak, i.e. 9th h in the dark phase, and peaks after 9 h in light, i.e. 9th h in the light phase. The contents of (-)--pinene in juvenile leaves and in emitted volatiles also vary in a diurnal rhythm, correlating strongly with mRNA accumulation 653533 4.2.3.119 up expression is induced upon wounding or methyljasmonate treatment 730575 4.2.3.119 up significant increase in transcript level in the leaders of lateral branches of weevil-attacked and mechanically wounded trees 718229 4.2.3.119 up upon methyljasmonate treatment, expression is significantly induced in medium and old leaves 730632
