Rice plant architecture and stress tolerance have historically been primary concerns for rice breeders. The "Green Revolution" and super-rice breeding practices have demonstrated that ideal plant architecture can effectively improve both stress tolerance and yield. The synergistic selection and breeding of rice varieties with ideal architecture and stress tolerance can increase and stabilize yield. While rice plant plant architecture and stress tolerance are separately regulated by complicated genetic networks, the molecular mechanisms underlying their relationships and synergism have not yet been explored. In this paper, we review the regulatory mechanism between plant architecture, stress tolerance, and biological defense at the different level to provide a theoretical basis for the genetic network of the synergistic regulation and improvement of multiple traits.
水稻株型与抗逆性一直是水稻育种家关注的主要问题。“绿色革命”和超级稻育种实践表明，理想的株型能够有效提高抗逆性和产量。协同选育具有理想株型和抗逆性的水稻品种能够提高产量并使其稳定。虽然水稻株型和抗逆性分别由复杂的遗传网络调控，但其相互关系和协同作用的分子机制尚未得到探索。本文综述了不同水平上株型、抗逆性和生物防御之间的调控机制，为多性状协同调控与改良的遗传网络提供理论依据。
