摘要： Tomato is an important vegetable plant worldwide. Previously, we isolated a soilborne Actinobacteria species, Streptomyces lydicus A01, which promotes the growth of tomato seedlings. The related mechanisms are needed to study. RNA sequencing and gas chromatography-mass spectrometry were used reveal the global effect of S. lydicus A01 on tomato seedlings. Liquid chromatography-mass spectrometry was used to detect plant hormones in tomato seedlings during the growth-promotion procedure. After administration of S. lydicus A01, tomato seedlings exhibit more vigorous growth with more leaflets and improved photosynthesis. It was revealed that S. lydicus A01 has some effects on the basic metabolism of tomato seedlings. Meanwhile, the biosynthesis of secondary metabolites related to plant growth was regulated, including cutin, suberine, wax and flavonoid. Additionally, plant hormones including abscisic acid, salicylic acid and jasmonic acid were discovered to involve in the plant-growth-promoting activity of S. lydicus A01. This study revealed some growth-promoting mechanisms of tomato seedlings by S. lydicus A01, laying the groundwork for further research.
