Abstract:
-Penicillium digitatum (green mold) and Penicillium italicum (blue mold) are threatening post-harvest pathogens of citrus fruit causing huge economic loss. In this study salicylic acid (SA) and Cinnamomum verum were tested to suppress the infection of P. digitatum and P. italicum. Methanolic extracts of five plants were tested in vitro for antifungal activity where C. verum exhibited the highest colony growth inhibition of green and blue mold, respectively. Moreover, during In Planta assay the combination of SA and C. verum caused the lowest disease incidence and severity of green and blue mold respectively compared to stand-alone treatments with no effect on fruit quality. Furthermore, an upregulation in the activity of peroxidase (POD), polyphenol oxidase (PPO), and phenylalanine ammonia lyase (PAL) encoding genes of citrus fruit was recorded during transcriptional profiling. The highest expression of defense genes was recorded in fruit treated with C. verum and SA in combination than healthy control. The spectrophotometric quantification of corresponding gene products also revealed similar results. The study unveils the fact that the increased expression of defense-related genes might be associated with the enhanced disease suppression. Conclusively, our results indicate that C. verum and SA in combination can suppress green and blue mold of Citrus by modulating the expression of defense genes. The combination of botanical extracts and resistance inducers is a safer alternate to chemicals for the suppression of green and blue mold.
