The function of plant jasmine acid desensiting protein complex is revealed.

Like humans, plants initiate their own immune responses in the face of adverse environments, which rely heavily on a plant hormone called jasmine acid (JA).
but along with biological evolution, some plants are no longer sensitive to this hormone and relying solely on jasmine acid does not stimulate their own immune response.
a new study by Nanjing Agricultural University found that the key JAZ protein in the plant jasmine acid signaling pathway mutated, resulting in changes in protein function.
reveal that this important "gate" affecting plant epidemic prevention mechanism provides an important basis for changing the thinking of traditional plant pest control and research and development of new technologies.
findings were published recently in the proceedings in the proceedings of the Proceedings of the National Academy of Sciences (PNAS), an authoritative international journal.
" molecules is very fine, and our job is to explore the sophisticated world of molecular interaction in plants at the atomic level.
Zhang Feng, lead author of the paper and a professor at Nanjing Agricultural University's School of Plant Protection, told China Science Daily that scientists have been studying jasmine acid (JA), an important plant hormone, for nearly half a century.
they wanted to understand why, as living things evolved, plants ben less sensitive to jasmine acid and plants' anti-epidemic responses could not be activated. Studies have reported that the key jasmine desensiting protein complex in plants regulates the rebalancing of hormones in plants after the jasmine signal is activated, preventing jasmine acid signals from losing control.
that the epidemic response of plants cannot be activated, does that mean that plants have no resistance to adverse environments? So shouldn't scientists try to avoid this?"This is the traditional thinking of disease prevention and control, and it is believed that plants should be stimulated to initiate defensive responses to the maximum extent possible, " said Zhou Mingguo, author of the paper and a professor at nanjing Agricultural University's School of Plant Protection.
in fact, plants in the process of starting defense will be accompanied by their own large energy loss, the result is that the disease is contained, plants also grow 'tuming'.
" Zhou Mingguo said the significance of the study lies in how to "partially" play a defensive response suppression function, in the plant's "defense" and "growth" to achieve a good balance.
it is understood that the research team at Nanjing Agricultural University has previously revealed the inhibition and activation mechanisms of plant defense reactions through extensive collaboration, the results of which were published in the journal Nature in 2015.
" If previous studies have found the equivalent of finding a 'switch' to control plant defense reactions, then the revelation of the function of the plant jasmine desensitum complex allows us to hold a 'gate' between plant defense and growth regulation.
In controlling the open range of 'gates', we can rely on the in-house immune response of plants in part, and the use of external chemical fungicides in the other, using the synergy between the two to achieve disease prevention and crop growth of the 'one arrow and two carvings', which will greatly improve the use of chemical pesticides.
