Plant-associated microbiomes have been suggested as pivotal for the growth and health of natural vegetation and agronomic plants. In this sense, plant-associated microbiomes harbor a huge diversity of microorganisms (such as bacteria and fungi) which can modulate the plant host response against pathogens and changing environmental conditions through a complex network of genetic, biochemical, physical, and metabolomics interactions. Advances on next-generation omic technologies have opened the possibility to unravel this complex microbial diversity and their interactive networks as never described before. In parallel, the develop of novel culture-dependent methods are also crucial to the study of the biology of members of plant-associated microbiomes and their bioprospecting as sources of bioactive compounds, or as tools to improve the productivity of agriculture. This Special Issue aims to motivate and collect recent studies which are focused on exploring the diversity and ecology of plant-associated microbiomes and their genetic and metabolic interactions with other microorganisms or their plant hosts, as well as their potential biotechnological applications in diverse fields, such as inoculants for agriculture.

植物相关微生物群的多样性，相互作用和生物勘探

与植物相关的微生物群已被认为对天然植被和农艺植物的生长和健康至关重要。从这个意义上说，与植物相关的微生物群具有多种多样的微生物（例如细菌和真菌），它们可以通过复杂的遗传，生化，物理和代谢组学相互作用网络来调节植物宿主对病原体的反应并改变环境条件。下一代Omic技术的进步为揭示这种复杂的微生物多样性及其互动网络提供了可能性，这是以前从未描述过的。同时，新的依赖文化的方法的发展对于研究与植物相关的微生物群成员的生物学及其作为生物活性化合物的来源的生物前景也至关重要，或作为提高农业生产力的工具。本期专刊旨在激发和收集最近的研究，这些研究的重点是探索植物相关微生物群的多样性和生态学，以及它们与其他微生物或其植物宿主的遗传和代谢相互作用，以及它们在不同领域的潜在生物技术应用，例如作为农业的孕育剂。
