Hypomorphic alleles reveal FCA-independent roles for FY in the regulation of FLOWERING LOCUS C.

Plant physiology - 1 Mar 2011

Abstract excerpt

The autonomous floral promotion pathway plays a key role in the regulation of flowering in rapid-cycling Arabidopsis (Arabidopsis thaliana) by providing constitutive repression of the floral inhibitor FLOWERING LOCUS C (FLC). As a result, autonomous pathway mutants contain elevated levels of FLC and are late flowering. Winter annual Arabidopsis, in contrast, contain functional alleles of FRIGIDA (FRI), which acts...
