比利时图卢兹大学Pierre-Marc Delaux 和英国剑桥大学Sebastian Schornack研究组合作综述了共生和病原微生物的相互作用促进植物进化。 相关论文于2021年2月19日发表在国际学术期刊《科学》杂志上。

研究人员介绍了共生不断出现的保护机制和一般细胞生物学原理的共同选择。探索和利用非开花植物-微生物相互作用中使用的分子机制多样性，可能为工程化扩展共生能力和病原体适应性作物提出了可能。

研究人员介绍，在4.5亿年的土地多样化中，植物与微生物共同进化。这种关系一直延续至今，并且经历了从寄生到互利共生的演变。通过系统发育学、细胞生物学和反向遗传学，从开花植物到苔藓植物，科学家已经开始揭示植物-微生物网络的遗传基础和进化轨迹。保守和进化枝特有的植物机制以不同的速度发展，并可以抵抗病原体和促进有益的共生微生物。

Title: Plant evolution driven by interactions with symbiotic and pathogenic microbes

Abstract: During 450 million years of diversification on land, plants and microbes have evolved together. This is reflected in today’s continuum of associations, ranging from parasitism to mutualism. Through phylogenetics, cell biology, and reverse genetics extending beyond flowering plants into bryophytes, scientists have started to unravel the genetic basis and evolutionary trajectories of plant-microbe associations. Protection against pathogens and support of beneficial, symbiotic, microorganisms are sustained by a blend of conserved and clade-specific plant mechanisms evolving at different speeds. We propose that symbiosis consistently emerges from the co-option of protection mechanisms and general cell biology principles. Exploring and harnessing the diversity of molecular mechanisms used in nonflowering plant-microbe interactions may extend the possibilities for engineering symbiosis-competent and pathogen-resilient crops.
