Interpretive Summary:

Technical Abstract: Reniform nematode (Rotylenchulus reniformis) is an economically important microparasite, which could cause severe yield loss in cotton production. Studying the transcriptomes of resistant cotton varieties under the pressure of reniform nematodes may identify genes involved in plant defense responses. Four resistant cotton lines, including two G. arboreum accessions PI 529728 (A2-100) and PI 615699 (A2-190), and two G. barbadense lines GB-713 and TX100, were inoculated with reniform nematodes. Three biological samples were collected from inoculated and uninoculated plants of each line five and nine days post inoculation. Transcriptome analysis revealed differentially expressed genes. Chromosomal locations were determined for these genes as well as their potential functions in plant defense reactions. Some differentially expressed genes identified in this research will be further studied to explore possible applications in developing cotton cultivars resistant to reniform nematodes.
