Overall, this study has identified QTL and markers linked to CBB infection trait, and identified candidate genes involved in CBB resistance. The expression pattern of all genes showed higher levels in resistant (B82, B32, B20, and B70) as compared to susceptible (HB60, B100, B95, and B47) plants. The results identified candidate genes that showed significant differences in expression between resistant and susceptible lines, including brassinosteroid insensitive 1-associated receptor kinase 1-related ( Manes.04G059100), cyclic nucleotide-gated ion channel 2 ( Manes.02G051100), and autophagy-related protein 8a-related ( Manes.17G026600) at 7 DAI, and regulator of nonsense transcripts 1 homolog ( Manes.17G021900) at both 7 and 12 DAI. Genes underlying the QTL were identified and their expression was investigated in resistant and susceptible cassava plants by real-time quantitative RT-PCR. Among all identified QTL, CBB14_10dai_1, CBB14_10dai_2, and CBB14_12dai showed the most significant ( P < 0.0001) associations with CBB infection, and explained 21.3, 13.8, and 26.5% of phenotypic variation, respectively. A total of 12 QTL were identified, of which 5, 6, and 1 were detected in 7, 10, and 12 DAI samples, respectively. The phenotype of disease severity was observed at 7, 10, and 12 days after inoculation (DAI). ![]() In this study, quantitative trait loci (QTL) associated with CBB infection were identified in the F1 progenies of a cross between the “Huay Bong 60” and “Hanatee” cassava cultivars. manihotis (or XAM) is a serious disease of cassava ( Manihot esculenta Crantz).
