Making bigger plants: key regulators of final organ size.

摘要: Organ growth in plants is controlled by both genetic factors and environmental inputs. Recent progress has been made identifying determinants of final organ size characterizing a pathway that may link with conditions. Some identified regulatory act downstream plant hormones, while others appear to be components novel signaling pathways. Additional characterization these proteins needed before we can understand how growth-promoting growth-restricting inputs are integrated coordinate within developing organ. parallels the mechanisms used animals regulate suggested identification KLUH, noncell-autonomous regulator growth, similarities target rapamycin (TOR)-signaling pathway.
