Plants are continuously exposed to numerous biotic stresses throughout their *** arms race-driven coevolution with pathogens,plants have developed sophisticated immune systems,including pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI)and effector-triggered immunity(ETI).PTI is initiated by the binding of danger signals to extracellular membrane-localized receptors calledpattern recognition receptors(PRRs).PTI triggers responses,including reactive oxygen species(ROS)bursts and the expression of defenseassociated ***,pathogens adapted to PTl secrete virulence proteins,effectors,to aid colonization,and ETl is then triggered by the recognition of these effectors by resistance proteins with a nucleotide-binding domain leucinerich repeat receptor(NLR).To circumvent this immune response,pathogens secrete various effectors into the host intracellular region and induce effector-triggered susceptibility(Zhou and Zhang.,2020).Currently,research on plant immunity has been primarily focused on plasma membrane and cytoplasmlocalized proteins,including oligomeric NLRs,resistosomes,and the secretion mechanisms of cytoplasmic effectors.

The mechanism involved in the phase transformation process of pyrolusite (MnO_(2)) during roasting in a reducing atmosphere was systematically elucidated in this study,with the aim of effectively using low-grade complex manganese ore *** to single-factor experiment results,the roasted product with a divalent manganese (Mn^(2+)) distribution rate of 95.30% was obtained at a roasting time of 25 min,a roasting temperature of 700℃,a CO concentration of 20at%,and a total gas volume of 500 mL·min^(-1),in which the manganese was mainly in the form of manganosite (MnO).Scanning electron microscopy and Brunauer–Emmett–Teller theory demonstrated the microstructural evolution of the roasted product and the gradual reduction in the pyrolusite ore from the surface to the core Thermodynamic calculations,X-ray photoelectron spectroscopy,and X-ray diffractometry analyses determined that the phase transformation of pyrolusite followed the order of MnO_(2)→Mn_(2)O_(3)→Mn_(3)O_(4)→MnO phase by phase,and the reduction of manganese oxides in each valence state proceeded simultaneously.
