Protein function
Encodes a zinc finger protein involved in mRNA processing.
Phenotype
Multiple mutant: hua1;
hua2 multiple mutant shows developmental flower defects.
[Chen et al., 1999][Li et al., 2001][Cheng et al., 2003][Western et al., 2002] Remarks: hua2 mutation enhances the early-flowering phenotype of the
elf4 mutant and largely suppresses the late flowering-time phenotype of Col
FRI background.
[Doyle et al., 2005] Overexpressor: HUA2 overexpressor is late flowering under both SD and LD conditions.
[Wang et al., 2007] Remarks: hua2 single mutant has reduced
FLC expression levels while
HUA2 overexpressor has increased
FLC expression levels.
[Wang et al., 2007] Single mutant: hua2 single mutant is early flowering under both SD and LD conditions.
[Wang et al., 2007][Doyle et al., 2005][Ilk et al., 2015][Jali et al., 2014] Remarks: HUA2 is involved in the control of
AGAMOUS mRNA processing.
[Cheng et al., 2003] Function:Transcription factor that functions as repressor of flowering by enhancing the expression of several genes that delay flowering including FLC, FLM/MAF1, MAF2 and SVP. Also acts in the floral homeotic AGAMOUS (AG) pathway, specifically by processing the AGAMOUS pre-mRNA. Involved in all three aspects of the AG functions, the specification of stamen and carpel identities, the control of floral determinacy, and the spatial restriction of AP1 expression (PubMed:10198637, PubMed:12530963, PubMed:15659097). Acts as transcription regulator that controls anthocyanin accumulation (PubMed:25425527).
