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.

采用ＣＯ２激光器对Ｃｏ＋Ｎｉ烧结体和碳钢两种不同材料的可焊性进行了研究。采用不同功率和运转速度参数对两种材料进行了ＣＯ２激光对接焊。为研究其可焊性进行十力学测试（抗弯强度测试，显微硬度测试）和金相分析（显微结构，相转变和破坏模式）。明显地影响抗育强度的参数是气孔，输入能量的大小和焊接金属的重叠性能。为达到足够有效的强度，能量输入（线能量）必须大于０．３ｋＪ／ｍ，深宽比大于０．９，焊接金属中的气孔率应小于２０％。本文中展示了每部分的显微组织结构，基体部分为回火马氏体，热影响区为马氏体，焊缝金属部分则由奥氏体与变晶片状马氏体混合构成。
