MS2. Abstract: summarizes the paper in 250 words or less.

DWD proteins have been reported as substrate receptors for cullin–RING ubiquitin ligase 4 (CRL4). Upon screening T-DNA mutants of DWD genes for abscisic acid (ABA) responses we obtained several candidates which exhibited ABA-hypersensitivity and one was named DWA3 (DWD hypersensitive to ABA 3). DWA3 associated with the CRL4 components DDB1 and CUL4, indicating that DWA3 may function as a substrate receptor for CRL4. ABA-inducible transcription factors (ABI5 and AtMYC2) and their downstream genes were hyper-induced by ABA in dwa3. Taken together, we suggest DWA3 is a negative regulator of ABA responses and may be involved in protein degradation mediated by CRL4.
