TL;DR
The ANTHOCYANINLESS2 gene was isolated from Arabidopsis by using the maize Enhancer–Inhibitor transposon tagging system and encodes a homeodomain protein belonging to the HD–GLABRA2 group, which is involved in the accumulation of anthocyanin and in root development.
Abstract
The ANTHOCYANINLESS2 (ANL2) gene was isolated from Arabidopsis by using the maize Enhancer-Inhibitor transposon tagging system. Sequencing of the ANL2 gene showed that it encodes a homeodomain protein belonging to the HD-GLABRA2 group. As we report here, this homeobox gene is involved in the accumulation of anthocyanin and in root development. Histological observations of the anl2 mutant revealed that the accumulation of anthocyanin was greatly suppressed in subepidermal cells but only slightly reduced in epidermal cells. Furthermore, the primary roots of the anl2 mutant showed an aberrant cellular organization. We discuss a possible role of ANL2 in the accumulation of anthocyanin and cellular organization of the primary root.
