  1. The ability of LBD29 to regulate lateral root initiation is associated with its maintenance of the cell division capacity of the pericycle in response to auxin and its involvement in the auxin signalling pathway.
    [PMID: 22334497]
  2. Data show that overexpression of each of the LBD genes promotes callus formation in the absence of exogenous phytohormones, while suppression of LBD function inhibits the callus induction process.
    [PMID: 22508267]
  3. LBD16, LBD29, and LBD18 are involved in cell cycle progression of the pericycle in response to auxin.
