ARR1 Antibody

1. The expression signals of AG were detected in the initiating carpel primordia and regenerating carpels, and co-localized with those of two Type-B ARABIDOPSIS RESPONSE REGULATORs (ARRs), ARR1 and ARR10. PMID: 29186581
2. Data suggest that shoot removal induces the quantitative and qualitative development of chloroplasts in roots, with cytokinin signaling via RESPONSE REGULATOR (ARR)-ARR1 and ARR12 functioning downstream of wounding signaling to up-regulate genes associated with chloroplast development. PMID: 28193764
3. SCR mediates ARR1 transcriptional suppression via the RGA protein. PMID: 26848984
4. An arr1,10,12 triple mutant had more drought tolerance due to enhanced cell membrane integrity, anthocyanin synthesis, abscissic acid hypersensitivity, and reduced stomatal aperture. Dehydration and ABA repressed all 3 genes. RR1 is the most critical. PMID: 26884175
5. Cytokinin signaling increases the abundance of ARR1, a ubiquitously expressed type-B response regulators (RRB), by preventing its degradation by the 26S proteasome. PMID: 24617630
6. Data indicate that one of the immediate early cytokinin response genes is ARR6, which has been shown to be a direct target gene of ARR1, ARR2 and other type-B ARRs. PMID: 23620480
7. ARR1 mediates cold signal via AHP2 (Arabidopsis histidine kinase 2), AHP3, or AHP5. PMID: 23124324
8. A nitrosomimetic mutation of AHP1 causes reduced phosphorylation of AHP1 and ARR1, thereby resulting in a compromised cytokinin response. PMID: 23443557
9. arr1-1 mutation clearly affected the primary response in at least 17 genes, meaning that they respond primarily to cytokinins through the function of ARR1 PMID: 17202182
10. Suppression of pleiotropic cytokinin activities by a dominant repressor version of a B-type ARR indicates that this protein family is involved in mediating most, if not all, of the cytokinin activities. PMID: 18502977
11. ARR1 activates SHY2 gene, repressor of auxin signaling that negatively regulates PIN auxin transport facilitator genes: cytokinin causes auxin redistribution, prompting differentiation; auxin mediates degradation of SHY2, sustaining cell division PMID: 19039136
