Germplasm Phenotype:

• SALK_097442c  — atprmt4b-1 mutants do not have any obvious phenotypic defects when compared to wild-type plants. But, the double mutants atprmt4a-1 atprmt4b-1 and atprmt4a-2 atprmt4b-1 have delayed flowering under long days.
• atprmt4a-2 atprmt4b-1  — These double mutants have delayed flowering compared to wild type plants when grown under long day conditions. Analysis of growth under short day conditions indicates that these mutants are not disrupted in the photoperiod pathway. These double mutants also seem to be able to respond to vernalization signals and to gibberellin. But they have an impaired autonomous pathway to flowering. FLC transcripts are up-regulated in these double mutants through an unknown mechanism. The global level of asymmetric dimethylation of arginine 17 in histone 3 (H3)is reduced in these mutants. The transcript levels for several repressors of FLC do not seem to be altered in the double mutants, nor are there discernible changes in several types of H3 modifications at the FLC locus.
