Improving Crop Lodging Resistance by Adjusting Plant Height and Stem Strength

Crop height not only determines plant resistance to lodging and crowding, but also affects crop architecture, apical dominance, biomass, mechanical harvesting. Plant is determined by the internode elongation, regulated genes involved in gibberellin (GA) brassinosteroid (BR) biosynthesis or related signaling networks. Plants’ genetic inability synthesize respond GAs BRs induce dwarfness. However, mechanisms of for controlling individually collectively are still unclear. Since stem mechanically supports during whole life span, components that affect physical strength important resistance. One major lignin, which forms structure, thus contributing In this review, we looked into reported GAs, summarized networks centered these genes. Then, filled knowledge gap modifying through interrupting normal GA BR metabolism utilizing core gene inhibitors. Therefore, highly endorsed current approaches using growth regulators (PRGs) maintain an ideal under stress, proposed possibilities culm against as well.
