The core role of brassinolide in the regulation of tomato plant type revealed

Plant configuration affects plant light energy absorption, nutrient distribution and yield formation, while top dominance is a common phenomenon in higher plants and plays an important role in plant configuration.

On March 9, the Proceedings of the National Academy of Sciences of the United States published online a research paper by Professor Yu Jingquan’s team at Zhejiang University’s School of Agriculture and Biotechnology.

The study found that BR directly transcribes the BRANCHED1 (BRC1) gene specifically expressed in lateral buds through its key transcription factor BRASSINAZOLE-RESISTANT1 (BZR1) , and relieves its inhibitory effect on lateral bud activation.

The above results indicate that BR signal integrates multiple ways to control the occurrence of collaterals.

Professor Xia Xiaojian of Zhejiang University College of Agriculture and Biotechnology, PhD student Dong Han, PhD student Yin Yanling and PhD student Song Xuewei are the co-first authors of the paper, Yu Jingquan is the corresponding author, and Professor Foyer CH of the University of Birmingham is the co-corresponding author.
