|Title||A Leaf-Inhabiting Endophytic Bacterium, Rhodococcus sp. KB6, Enhances Sweet Potato Resistance to Black Rot Disease Caused by Ceratocystis fimbriata|
J. Microbiol. Biotechnol.2016 ;
|Abstract||Rhodococcus species have become increasingly important owing to their ability to degrade a
wide range of toxic chemicals and produce bioactive compounds. Here, we report isolation of
the Rhodococcus sp. KB6, which is a new leaf-inhabiting endophytic bacterium that suppresses
black rot disease in sweet potato leaves. We determined the 7.0 Mb draft genome sequence of
KB6 and have predicted 19 biosynthetic gene clusters for secondary metabolites, including
heterobactins, which are a new class of siderophores. Notably, we showed the first internal
colonization of host plants with Rhodococcus sp. KB6 and discuss its potential as a biocontrol
agent for sustainable agriculture.|
