The study zed1-D reveals a new mechanism for the dynamic balance between temperature-regulated plant development and disease-resistant response.

The growth and development of plants and the immune response are energy-consuming processes, and there is a dynamic balance between them.
high temperature conditions, plants need to suppress their own basic immune response while promoting growth and development, in order to ensure that more material and energy to meet their growth needs.
, little is known about the molecular mechanism of the dynamic balance between temperature-regulated plant growth and development and immune response.
Yuxin research team at the Institute of Botany of the Chinese Academy of Sciences found that the explicit negative mutation (zed1-D) of the athropomorphous ZED1 (HopZ-ETI-Deficient 1) can cause the immune response to self-activation and growth and development of plants at high temperatures.
ZED1-related Kinases family members and ZED1 are induced by high temperature expression, and there is functional redundancy.
further studies have found that the growth and developmental defects and disease-resistant activation esoterics of zed1-D depend on their mutually modified protein ZAR1 (HOPZ-Activated Resistance 1), while the resistance protein SNC1 (Suppressor of NPR1-1 Constitutive 1) is located downstream of the ZED1/ZAR1 signal and its gene expression is inhibited by ZRKs.
(A) wild-type athropomorthic mustard (WT) and zed1-D mutant espresso esograms at low temperature (18 degrees C), WT and zed1-D mutant espresso esomor at (B) high temperature (25 degrees C), (C) high temperature induced zed1-D reactive oxygen accumulation, and (D) ZRKs mediated temperature dependence between growth and development and immune response dynamic balance pattern map.
zed1-D is the first high-temperature sensitive immune self-activated mutant currently reported.
the mutant's research reveals a new mechanism for the dynamic balance between temperature-regulated plant development and disease-resistant response, which will deepen people's understanding of how plants regulate growth and development to adapt to extremely changing environments.
