| description | <p class="Normal1">Fertilizers and chemical pesticides supply plants’ nutritional requirements and protect them against pathogens. However, they may cause harm to the environment. <em>Pectobacterium</em> sp. has been reported as an endophyte with the capacity of a plant-growth promoter, especially in the control of phytopathogens. The current paper evaluates the capacity of the endophytic bacterium <em>Pectobacterium</em> sp. MG-60 isolated from <em>Mikania glomerata</em> Spreng. (Asteraceae) to antagonize phytopathogens <em>in vitro</em>, produce IAA, and fix nitrogen (<em>nif</em>H). Growth promotion assessments of bean and soybean plants under greenhouse conditions were also performed. The rate of antagonism against <em>Sclerotinia sclerotiorum</em> was 52.5%. The endophyte <em>Pectobacterium</em> sp. MG-60 produced 3.54 µg mL<sup>-1</sup> of IAA when 5 mM L-tryptophan in the culture medium was used. Under greenhouse conditions, significant results for <em>Pectobacterium</em> sp. MG-60 in the growth of soybean and common bean plants were observed, especially in the height of common bean (19%) and soybean (20%), fresh weight of shoot (18.5%) and fresh weight of roots (46.8 %) of soybean plants. This is the first report on <em>Pectobacterium</em> isolated as an endophyte from <em>M. glomerata</em> with plant growth-promoting agent abilities with biotechnological potential for the agricultural field.</p> |
