Gram-positive bacteria are prominent members of plant-associated microbial communities. Although many are hypothesized to be beneficial, some are causative agents of economically important diseases of crop plants. Because the features of Gram-positive bacteria are fundamentally different relative to those of Gram-negative bacteria, the evolution and ecology as well as the mechanisms used to colonize and infect plants also differ. Here, we discuss recent advances in our understanding of Gram-positive, plant-associated bacteria and provide a framework for future research directions on these important plant symbionts.

革兰氏阳性植物相关细菌的进化，生态学和感染机制。

革兰氏阳性细菌是植物相关微生物群落的重要成员。尽管许多被认为是有益的，但有些是作物经济上重要疾病的病原体。由于革兰氏阳性细菌的特征与革兰氏阴性细菌的特征根本不同，因此进化和生态以及用于定植和感染植物的机制也不同。在这里，我们讨论了我们对革兰氏阳性植物相关细菌的了解的最新进展，并为这些重要的植物共生体的未来研究方向提供了框架。
