Data on the ultrastructural characteristics of Paenibacillus polymyxa isolates and biocontrol efficacy of P. polymyxa ShX301

摘要

We present the data corresponding to the ultrastructural characteristics ofPaenibacillus polymyxaisolates and control efficacy ofP. polymyxaShX301 for controlling Verticillium wilt of cotton, isolated in experimental fields at the Sanyuan Agricultural Experiment Station of North-West Agriculture and Forestry University, Sanyuan county, Shaanxi province, China. Ultrastructural characteristics ofP. polymyxaisolates made using technique of transmission electron microscopy. A strain ShX301 has a broad-spectrum antifungal activity againstV. dahliaeand other plant pathogens and has been used forin vitroexperiments for controlling this disease in greenhouse, "Biocontrol potential ofPaenibacillus polymyxaagainstVerticillium dahliaeinfecting cotton plants" .
