| Summary: | <i>Medicago sativa</i> is an important forage crop; its value is mainly concentrated in its economic aspects. The growth cycle and growth rate of <i>M. sativa</i> have an important influence on its economic benefits. <i>Alternaria alstroemeriae</i> has often been used as a pathogenic bacterium in previous studies, and studies on the growth-promoting effects of <i>A. alstroemeriae</i> are rare. This study aimed to assess the effects of <i>A. alstroemeriae</i> on the growth parameters of <i>M. sativae</i> and to investigate the molecular and metabolic mechanisms of <i>M. sativa</i>. <i>M. sativa</i> showed significant improvement in plant height, root length, fresh weight, and dry weight compared to uninoculated control plants. By integrating the results of transcriptome and metabolome analysis, <i>A. alstroemeriae</i> may promote plant growth by regulating genes associated with the biosynthetic pathways of flavonoids, anthocyanins, and proanthocyanidins in plants. These research findings provide a theoretical basis for future verification of the molecular response mechanisms and metabolic regulation of <i>A. alstroemeriae</i>-promoted plant growth. This study also provides a theoretical basis for sustainable agricultural development. |
