Researcher Wang Bing from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, Makes Significant Progress in Plant Hormone Signaling Mechanism with the BPC600H Incubator
Under the guidance of Academician Li Jiayang, Researcher Wang Bing from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, conducted analytical experiments using the Jiupo BPC600H incubator. The research made significant advancements in understanding the signaling mechanism of strigolactone in plants, uncovering a new mechanism by which low nitrogen conditions regulate strigolactone signaling to inhibit rice tillering development.

Strigolactones are an important class of plant hormones recently discovered to play a critical role in regulating key growth traits, such as the number of branches (tillering) in plants. The team led by Academician Li Jiayang at the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, is internationally recognized as a leader in this field. Their research was included in the “Top Ten Scientific Advances in China in 2014.”
On the evening of November 4, 2024, Beijing time, this groundbreaking research was published online in the journal Cell.

Reviewers have highly praised the study, noting that “the research systematically analyzes the mechanism of strigolactone signaling perception using extensive biochemical and genetic data, revealing new features of the signaling mechanism.” They also highlighted “exciting new discoveries, such as the post-translational modifications of D14 and its role in low nitrogen adaptation,” and emphasized that “the data is robust, and the experimental design is ingenious, resolving disputes among different models of strigolactone signaling perception, offering a new perspective on the regulatory mechanisms of strigolactone signaling.”
This study elucidates the activation, regulation, and termination mechanisms of strigolactone signaling in rice. It uncovers a new regulatory mechanism between ubiquitination modification and protein degradation, revealing a novel mechanism by which D14 regulates its stability through phosphorylation, playing a central role in rice tillering response to low nitrogen environments. These findings provide important guidance for the precise improvement of crop plant architecture and the molecular breeding of new rice varieties that increase yields while reducing fertilizer use.
