説明
<jats:p> The application of bacteria as plant growth promoters is a sustainable alternative to mitigate the use of chemical fertilization in agriculture, reducing negative economic and environmental impacts. Several plant growth-promoting bacteria synthesize and accumulate the intracellular polymer polyhydroxybutyrate (PHB). However, the role of PHB in plant-bacterium interactions is poorly understood. In this study, applying the C4 model grass <jats:named-content content-type="genus-species">Setaria viridis</jats:named-content> and several mutants in the PHB metabolism of the endophyte <jats:named-content content-type="genus-species">Herbaspirillum seropedicae</jats:named-content> yielded new findings on the importance of PHB for bacterial colonization of <jats:named-content content-type="genus-species">S. viridis</jats:named-content> roots. Taken together, the results show that deletion of genes involved in the synthesis and degradation of PHB reduced the ability of the bacteria to enhance plant growth but with little effect on overall root colonization. The data suggest that PHB metabolism likely plays an important role in supporting specific metabolic routes utilized by the bacteria to stimulate plant growth. </jats:p>
