Overexpression of LtuHB6 from Liriodendron tulipifera causes lobed-leaf formation in Arabidopsis thaliana.

ABSTRACT: Liriodendron tulipifera L. is an ornamental tree species with extraordinarily lobed leaves. However, the mechanisms underlying lobed leaf formation in plants remain unclear. The transcription factor, ARABIDOPSIS THALIANA HOMEBOX 6 (HB6), plays a role in regulating leaf margin development. HB6 is involved in cell division and differentiation of developmental organs and negatively regulates abscisic acid (ABA) signal transmission under external abiotic stress; it is unclear whether HB6 performs a pivotal role in leaf morphogenesis in L. tulipifera. In this study, full-length LtuHB6 from L. tulipifera was heterologously expressed in tobacco and Arabidopsis thaliana; its expression pattern was analyzed to determine its potential role in leaf development.
