Interdisciplinary studies reveal the biometric regulation of the non-symmetrical development of leaves

how do animal and plant organs get asymmetrical shapes during development? A large number of molecular genetics studies have found many regulatory genes, but this basic developmental biology question has not been fully answered: people do not yet understand how genes guide the creation of organ shapes. As a typical plant organ, leaves are a good system for studying the production of organ asymmetry.
The Zhu Yuling Research Group of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences and the Long Ying Research Group of the Institute of Aesthetics of the Chinese Academy of Sciences have found the important role of biometrics in the production of organ shape asymmetry through cross-disciplinary research. The research shows that the polar distribution of signal molecules between the back and abdominal sides of the blade leads to the asymmetry of the cell wall properties in the leaf base, and the asymmetry of the methyl esterification modification of the phospherics in the cell wall participates in the asymmetry formation of the merrivity properties. Theoretical simulations show that aesthetic asymmetry can better explain the resulting asymmetry of organ shape, and it is particularly worth mentioning that experiments that artificially alter the properties of cell wall methylsterification to affect the properties of cell wall have verified the model prediction and found that the expression of the back/abdominal polarity gene can be changed. To sum up, aesthetic asymmetry may be a common mechanism for the production of organ asymmetry.
the results of the study, entitled "The Aesthetic Regulation of The Symmetry of Leaf Organs", were published in the Journal of
2017. Dr. Qi Jiyan (graduated), Wu Binbin and Dr. Feng Shiliang, postdoctoral fellows of the Jiao Yuling Research Group, are co-authors of the paper, and Co-author of the paper, and Co-author of the paper. Li Chuanyou Research Group, Zhou Weihua Research Group, Beijing University Life Sciences Public Instrument Platform and Brooke (Beijing) Technology Co., Ltd. also participated in the study. The research was funded by the Ministry of Science and Technology's 973 project, the National Natural Science Foundation of China, the Ministry of Central Group's "10,000 People Program" and the National Key Laboratory of Plant Genomics.
