Expressed in embryogenic cells, somatic embryos and seeds at the later stages of development. In the embryos, expressed in the procambium, the root and shoot meristem and the protoderm of the cotyledons. Not detected in the endosperm or the aleurone layer, in young leaves or roots. Expressed specifically in embryos, both zygotic and somatic. Present at low levels in globular embryos. At the heart-stage, accumulates throughout the peripheral regions of the embryo and in the mature torpedo embryo expressed in the meristematic regions. Up-regulated by abscisic acid. Completely disordered protein. Flexible and unstructured in solution. Belongs to the small hydrophilic plant seed protein family.
