Plants adjust the balance between growth and defence using photoreceptors and jasmonates. Levels of active jasmonates are reduced in a phytochrome B-dependent manner by upregulation of a 12-hydroxyjasmonate sulfotransferase, leading to increase in shade avoidance and decrease in defence.

植物利用感光细胞和茉莉酸酯调节生长和防御之间的平衡。通过上调12-羟基茉莉酮酸酯的磺基转移酶，植物茉莉酸酯的活性水平以植物色素B依赖性的方式降低，从而增加了避光性并降低了防御力。
