3.2.1.15 | additional information | IND and HEC3 are required for normal expression of ADPG1 in the silique dehiscence zone and seed abscission zone, respectively. Transcriptional regulation of ADPG1, ADPG2 and QRT2 by jasmonic acid, and of ADPG2 by ethylene. Jasmonic acid and ethylene act together with abscisic acid to regulate floral organ abscission, in part by promoting QRT2 expression | Arabidopsis thaliana |
EC Number | Application | Comment | Organism |

3.2.1.15 | additional information | ADPG1 and ADPG2 are essential for silique dehiscence. ADPG2 and QRT2 contribute to floral organ abscission, while all three genes contribute to anther dehiscence | Arabidopsis thaliana |

3.2.1.15 | additional information | under normal growing conditions, single adpg2 mutants appear similar to wild-type plants in terms of pod shatter and also produce monad pollen. Reduced pod shatter in adpg2-1 and adpg2-2 plants (and in double mutants with qrt2) when watering is ceased before overall plant senescence is complete. Siliques of the double-mutants adpg1-1 adpg2-1 and adpg1-2 adpg2-2 exhibit a more severe phenotype than do those of the adpg1 single mutants and fail to dehisce even if compressed. In terms of pod shatter and seed abscission, adpg2 qrt2 double mutants are similar to adpg2 single mutants, double mutants lacking both ADPG1 and QRT2 appear identical to adpg1 single mutants, and the adpg1-1 adpg2-1 qrt2-2 and adpg1-2 adpg2-2 qrt2-3 triple mutants resemble the adpg1 adpg2 double mutants | Arabidopsis thaliana |
