Promotes the tolerance to a range of metals, including cadmium (Cd), arsenic (As) and copper (Cu) and to oxidizing chemicals (e.g. diamide and tert-butyl hydroperoxide (t-BOOH)) (PubMed:18980652). May act as a chromatin remodeling factor for stress responses (PubMed:18980652). Negative regulator of flowering, especially during drought stress, probably to prevent precocious flower development and subsequent low seed set (PubMed:31540691). Repress the AP1 promoter in a SOC1-dependent manner (PubMed:31540691). Interacts with SOC1 in the nucleus. Observed in a subnuclear speckling pattern, discrete parts of the chromatin of the nucleosome. Mostly expressed in stems, shoots and leaves, and, to a lower extent, in siliques and seedlings (PubMed:18980652). Barely detectable in roots (PubMed:18980652). Lower levels in the dark than in white, red and far-red light (PubMed:18980652). Induced by wounding in an ATAF2-dependent manner (PubMed:22937923). Abolished ability to confer tolerance to stress (e.g. metals and oxidizing chemicals such as Cd, As, Cu, diamide or tert-butyl hydroperoxide (t-BOOH)) (PubMed:18980652). Early flowering under mild drought stress treatment (PubMed:31540691).
