Phytohormones are regulators of plant growth and development, which under different types of stress can play a fundamental role in a plant's adaptation and survival. Some of these phytohormones such as cytokinin, gibberellin, salicylic acid, auxin, and ethylene are also produced by plant growth-promoting bacteria (PGPB). In addition, numerous volatile organic compounds are released by PGPB and, like bacterial phytohormones, modulate plant physiology and genetics. In the present work we review the basic functions of these bacterial phytohormones during their interaction with different plant species. Moreover, we discuss the most recent advances of the beneficial effects on plant growth of the phytohormones produced by PGPB. Finally, we review some aspects of the cross-link between phytohormone production and other plant growth promotion (PGP) mechanisms. This work highlights the most recent advances in the essential functions performed by bacterial phytohormones and their potential application in agricultural production.
植物激素是植物生长和发育的调节剂，在不同类型的胁迫下，它们在植物的适应和生存中起着至关重要的作用。其中一些植物激素，如细胞分裂素、赤霉素、水杨酸、生长素和乙烯，也由植物促生细菌（PGPB）产生。此外，PGPB会释放大量挥发性有机化合物，这些化合物与细菌植物激素一样，能够调节植物的生理和遗传。在本研究中，我们综述了这些细菌植物激素在与不同植物物种相互作用过程中的基本功能。此外，我们还讨论了PGPB产生的植物激素对植物生长有益影响的最新进展。最后，我们综述了植物激素产生与其他植物促生（PGP）机制之间相互联系的一些方面。这项工作突出了细菌植物激素所执行的基本功能的最新进展及其在农业生产中的潜在应用。
