WebNov 4, 2013 · Background. N-MYC DOWN-REGULATED-LIKE (NDL) proteins interact with the Gβ subunit (AGB1) of the heterotrimeric G protein complex and play an important role in AGB1-dependent regulation of lateral root formation by affecting root auxin transport, auxin gradients and the steady-state levels of mRNA encoding the PIN-FORMED 2 and … WebThe Auxins facilitate cell division and root differentiation. Auxins induce cell division, cell elongation, and formation of callus in cultures. For example, 2,4-dichlorophenoxy acetic acid is one of the most commonly added auxins in plant cell cultures. The Cytokinins induce cell division and differentiation. Cytokinins promote RNA synthesis and
