Low-activity cryptochrome 1 plays a role in promoting stem elongation and flower initiation of mature <i>Arabidopsis</i> under blue light associated with low phytochrome activity
Yun Kong, Youbin Zheng
Abstract
To explore whether cryptochrome contributes to stem elongation and flowering promoted by blue lights associated with low phytochrome activity, wild-type Arabidopsis was compared with its cryptochrome-deficient mutants and cryptochrome-overexpressing transgenic plants. Results indicated that the promotion effects were mainly related to low CRY1 activity, despite partial involvement of high-activity CRY2.
