Other claims from this paper (7)
- Association Under drought stress, TaHDA8 is tuned to alleviate its inhibition of root elongation in wheat.
- Intervention effect Reduced TaHDA8 protein levels de-represses the DNA-binding ability of TaAREB3 in wheat.
- Mechanism The de-repressed DNA binding of TaAREB3 depends on retained acetylation at K248 and K281 in wheat.
- Association Restored DNA binding of TaAREB3 to the TaKOR1 promoter upregulates TaKOR1 expression in wheat.
- Association TaAREB3-driven root elongation in wheat is promoting through enhanced cell proliferation in the root meristem.
- Association Natural variations in the TaKOR1 promoter determine differences in TaAREB3 binding in wheat.
- Observation Wheat germplasm carrying the TaHDA8-TaAREB3-TaKOR1 regulatory module has been widely selected.
