High-stress resistance and yield are major goals in crop cultivation, which can be addressed by modifying plant architecture. Significant progress has been made in recent years to understand how plant architecture is controlled under various growth conditions, recognizing the central role phytohormones play in response to environmental stresses. miRNAs, transcription factors, and other associated proteins regulate plant architecture, mainly via the modulation of hormone homeostasis and signaling. To generate crop plants of ideal architecture, we propose simultaneous editing of multiple genes involved in the regulatory networks associated with plant architecture as a feasible strategy. This strategy can help to address the need to increase grain yield and/or stress resistance under the pressures of the ever-increasing world population and climate change.
高抗逆性和高产量是作物栽培的主要目标，可以通过改变植物结构来实现。近年来，人们在理解植物结构如何在各种生长条件下受到控制方面取得了重大进展，认识到植物激素在应对环境胁迫方面的核心作用。miRNA、转录因子和其他相关蛋白通过调节激素平衡和信号转导来调节植物结构。为了培育具有理想结构的作物植物，我们提出同时编辑与植物结构相关的调控网络中多个基因，这是一种可行的策略。该策略有助于满足在不断增长的世界人口和气候变化的压力下提高粮食产量和/或抗逆性的需求。
