title: A draft genome sequence ofPseudomonas veroniiR4: a grapevine (Vitis viniferaL.) root-associated strain with high biocontrol potential.
abstract: A new plant commensalPseudomonas veroniiisolate (strain R4) was identified from aXiphinema indexbiocontrol screen. Isolated from grapevine roots from vineyards in central Chile, the strain R4 exhibited a slower yet equivalently effective nematicide activity as the well-characterizedP. protegensCHA0. Whole genome sequencing of strain R4 and comparative analysis among the availablePseudomonasspp. genomes allowed for the identification of gene clusters that encode putative extracellular proteases and lipase synthesis and secretion systems, which are proposed to mediate-at least in part-the observed nematicidal activity. In addition, R4 strain presented relevant gene clusters related to metal tolerance, which is typical inP. veronii. Bioinformatics analyses also showed gene clusters associated with plant growth promoting activity, such as indole-3-acetic acid synthesis. In addition, the strain R4 genome presented a metabolic gene clusters associated with phosphate and ammonia biotransformation from soil, which could improve their availability for plants.
