Expressioni

Tissue specificityi

Expressed in leaves and pollen (at protein level). The spatial localization is regulated by miR398-mediated silencing. Mostly present in flowers, old rosette leaves and inflorescence, and, to a lower extent, in cauline leaves, stems and roots.3 Publications

Inductioni

Upon photosynthetically active radiation (PAR) (e.g. light fluence) increase and UV-B treatment. Accumulates in response to ozone fumigation. Induced in response to oxidative stress, via a reduction of miR398-mediated silencing. Repressed by sucrose in a miR398-mediated silencing-dependent manner. Induced by salt stress.4 Publications
