Nuclear-encoded sigma factor 6 (SIG6) is involved in the block of greening response in Arabidopsis thaliana.

American journal of botany - 1 Feb 2020

Abstract excerpt

PREMISE: Light is critical in the ability of plants to accumulate chlorophyll. When exposed to far-red (FR) light and then grown in white light in the absence of sucrose, wild-type seedlings fail to green in a response known as the FR block of greening (BOG). This response is controlled by phytochrome A through repression of protochlorophyllide reductase-encoding (POR) genes by FR light coupled with irreversible...
