NnDREB2 regulated by NnWOX1-1 is involved in adventitious root formation in lotus root (Nelumbo nucifera Gaertn.).

ABSTRACT:

Background

Lotus root, a crucial aquatic cash crop, demonstrates primary root atrophy, while developing adventitious roots critically mediate nutrient acquisition and product organ development. Previous investigation reveals the functional involvement of NnWOX1-1 in root development through transgenic Arabidopsis models.

Results

In this study, we demonstrated nuclear and membrane co-localization of NnWOX1-1 fluorescence signals in tobacco leaf epidermal cells. NnWOX1-1 overexpression significantly enhanced root elongation and increased root primordia formation in transgenic lotus root and Sagittaria trifolia plants. We identified NnDREB2C as a downstream target gene of NnWOX1-1. The 615 bp nucleotide sequence of NnDREB2C encoded a 205-amino acid polypeptide containing a cons
