Therefore, each phytochrome gene of rice has distinct roles, and all of the phytochrome actions coordinately control the critical daylength response of florigen expression in rice.

因此，水稻中每个光敏色素基因都有着独特的作用，这些光敏色素协同调控水稻成花素基因的表达对临界日长的应答。

The computer then detects that light and verifies that yes, the phytochrome turned on the gene.

Exposure to light changes the shape of the phytochrome, which allows it to turn a gene on, so the gene will produce its particular protein.

The phytochrome can then be exposed to a different shade of red light to turn the gene off.
