Application of soybean GmPID4 gene in plant type regulation and shade tolerance breeding of soybean
By overexpressing the GmPID4 gene in soybeans, the plant architecture of soybeans was optimized, which solved the problems of thin and long stems and high lodging rate under dense planting and intercropping, and achieved thicker soybean stems, enhanced lodging resistance, and increased soybean yield.

Abstract
本发明涉及功能基因育种领域，本发明公开了一种大豆GmPID4基因在株型调控与耐荫大豆育种中的应用，通过过表达GmPID4基因并在正常光照条件下和荫蔽条件下对比其与野生型植株的株型变化，发现过表达植株在正常光照条件下株高小于野生型；在荫蔽条件下茎秆增粗，下胚轴比例缩短，植株抗倒伏能力提升。本发明开发了大豆GmPID4基因的新应用，能够优化大豆主茎纵向比例，促进基部横向增粗，实现大豆耐荫抗倒，为培育耐荫大豆提供了新的基因资源。
