Specific expression of AtIRT1 in phloem companion cells suggests its role in iron translocation in aboveground plant organs.

Plant signaling & behavior - 2 Sept 2021

Abstract excerpt

IRON-REGULATED TRANSPORTER 1 (IRT1) is a central iron transporter responsible for the uptake of iron from the rhizosphere to root epidermal cells. This study uses immunohistochemistry, histochemistry, and fluorometry to show that this gene's promoter is also active in the aboveground parts, specifically in phloem companied cells. Promoter activity here was regulated by iron as it was in the roots. The promoter of...
