Identification of Pratylenchus coffeae as a causal agent of root rot disease in Sorghum bicolor in China.

ABSTRACT: Sorghum (Sorghum bicolor) is an important food and feed crop. Root-lesion nematodes (Pratylenchus spp.) are a group of pathogenic nematodes that cause severe economic losses in various food and cash crops. This study identified diseased sorghum plants with stunted growth and brown, rotting roots in sorghum fields in Shanxi Province, China. A species of root-lesion nematode was isolated by modified Baermann funnel method and named the GL-1 population. Afterward, the GL-1 population of root-lesion nematodes was identified as P. coffeae through a combination of morphological, rDNA-ITS and rDNA-28 S D2-D3 region techniques for molecular biological identification. We also conducted greenhouse experiments to assess the parasitism and pathogenicity of GL-1 and four other P. coffeae populations on
