Gibberellin in plant height control: old player, new story.
Height relates to plant architecture, lodging resistance, and yield performance. Growth-promoting phytohormones gibberellins (GAs) play a pivotal role in plant height control. Mutations in GA biosynthesis, metabolism, and signaling cascades influence plant height. Moreover, GA interacts with other phytohormones in the modulation of plant height. Here, we first briefly describe the regulation of plant height by altered GA pathway. Then, we depict effects of the crosstalk between GA and other phytohormones on plant height. We also dissect the co-localization of GA pathway genes and established quantitative genetic loci for plant height. Finally, we suggest ways forward for the application of hormone GA knowledge in breeding of crops with plant height ideotypes.
