The transcriptic control factors MYC2, MYC3 and MYC4 (MYC2/3/4) activated by jasmine acid coordinated the regulation of the flowering induction of the adhesic mustard.

Reproduction is one of the most important stages in the life cycle of organisms.
in quilt plants, flowering makes the plant transition from the nutrient growth stage to the reproductive growth stage, thus ensuring the production of plant seeds. the process of flowering
plants is regulated by internal and external factors, various signal networks and many genes.
previous studies have shown that, in addition to the traditional flowering induction pathway, the plant hormone jasmine acid signaling pathway is also involved in the flowering induction process;
recently, the Chinese Academy of Sciences Xishuangbanna Tropical Botanical Garden plant molecular biology research group and plant environmental adaptability research group joint study found that jasmine-activated transcription control factors MYC2, MYC3 and MYC4 (MYC2/3/4) coordinated regulation of the flowering induction of admin mustard.
phenotype analysis showed that the flowering time of myc2/3/4 three mutant plants was significantly earlier than that of wild type.
gene expression analysis confirmed that the expression level of the conosin gene FT improved significantly in the context of myc2/3/4 mutants, while MYC2/3/4 showed similar space-time expression patterns with FT.
test results of chromatin immunoprecipitation show that MYC2 can bind directly to the chromosome region of FT gene and inhibit its transcription. In addition,
, the external application of jasmine acid can effectively inhibit plant flowering and the transcription of THE FT gene, but this process depends in part on the MYC2/3/4 gene.
, the study confirms that in the pattern plant amoeba, jasmine acid inhibits the transcription of FT genes by its activated transcription factor MYC2/3/4 to inhibit plant flowering induction.
related research in the case of the bHLHhion factors myC2, MYC3, and MYC4 are required for Jasmonate-Mediated inhibition of the flowering in Arabidopsis, published in TheMolecular Plant.
