Expressioni

Tissue specificityi

Expressed in root phloem and leaf mesophyll. Expressed in phloem tissues and aleurone layers of seeds and at lower levels in the pericarp and endosperm cells (at protein level). Predominantly expressed in elongating tissues including roots, developing leaves and internodes.2 Publications

Developmental stagei

Expressed early in seed development and then declines gradually and disappears (at protein level). In the caryopse, strongly expressed during the pre-storage phase, and the expression decreased thereafter.3 Publications

Inductioni

Up-regulated by sucrose, fructose and glucose. Up-regulated under elevated CO2 condition.2 Publications
