Two novel full-length NPR1-like genes; MNPR1A and MNPR1B, were isolated by application of the PCR and RACE techniques. The two identified MNPR1-sequences differed greatly in their expression profile using qRT-PCR following either elicitor or Foc treatment. MNPR1A was greatly expressed after Foc treatment with higher and earlier expression in the Foc-tolerant cultivar GCTCV-218 than in the sensitive cultivar Grand Naine. In comparison, MNPR1B was highly responsive to SA, but not to MeJA treatment, in both the tolerant banana cultivar GCTCV-218 and the more sensitive cultivar Grand Naine. Expression of the MNPR1 genes further directly related to PR gene expression known to be involved in fungal resistance. Reduced sensitivity to Foc in GCTCV-218 might be partially attributed to the higher and an earlier expression of both MNPR1A and PR-1 in this cultivar after Foc treatmenenElicitorNPR-1BananaMusaFusarium oxysporumPR proteinsMNPR1AMNPR1BPlant scienceMicrologyAgricultural biotechnologyElicitor and fusarium-induced expression of NPR-1 like genes in bananaArticleEndah, R., Beyene, G., Kiggundu, A., Van den Berg, N., Schlüter, U., Kunert, K., & Chikwamba, R.
