Maize is a major staple crop widely used as food,animal feed,and raw materials in in-dustrial production.High-density planting is a major factor contributing to the continuous in-crease of maize yield.However,high planting density usually triggers a shade avoidance response and causes increased plant height and ear height,resulting in lodging and yield loss.Reduced plant height and ear height,more erect leaf angle,reduced tassel branch number,earlier flowering,and strong root system ar-chitecture are five key morphological traits re-quired for maize adaption to high-density planting.In this review,we summarize recent advances in deciphering the genetic and mo-lecular mechanisms of maize involved in re-sponse to high-density planting.We also dis-cuss some strategies for breeding advanced maize cultivars with superior performance under high-density planting conditions.
