Recently, "mBio", an international authoritative journal in the field of microbiology, published online a research article by Professor He Yawen's team from the School of Life Science and Technology, Shanghai Jiaotong University, "The plant defense signal salicylic acid increases the intracellular and extracellular pH of the phytopathogenic Xanthomonas spp.
Xanthomonas is a class of Gram-negative bacteria that can infect more than 400 kinds of plants, including many important crops and cash crops, causing serious economic losses
Figure 1.
Further research found that with the growth of Xanthomonas Xcc in XYS medium, the pH value of the culture system gradually decreased to an acidic environment (~4.
SA is an important plant defense hormone, and the current research focus is the signal transduction pathway and induced immune response of SA in plants
This research was supported by the National Key R&D Program, the National Natural Science Foundation of China, and Shanghai Nongle Biological Products Co.
