In this study, a laboratory anti-CMV activity screening model for <i>Passiflora</i> spp. CMV disease was first established. Then, the effects of different antiviral agents of chitosan oligosaccharide (COS), dufulin (DFL), and ningnanmycin (Ning) on CMV virulence rate in <i>Passiflora</i> spp. were determined. The virulence rate and anti-CMV activity in <i>Passiflora</i> spp. treated with COS were 50% and 45.48%, respectively, which were even better than those of DFL (66.67% and 27.30%, respectively) and Ning (83.30% and 9.17%, respectively). Field trials test results showed COS revealed better average control efficiency (47.35%) against <i>Passiflora</i> spp. CMV disease than those of DFL (40.93%) and Ning (33.82%), indicating that COS is effective in the control of the <i>Passiflora</i> spp. CMV disease. Meanwhile, the nutritional quality test results showed that COS could increase the contents of soluble solids, titratable acids, vitamin C, and soluble proteins in <i>Passiflora</i> spp. fruits as well as enhance the polyphenol oxidase (PPO), superoxide dismutase (SOD), and peroxidase (POD) activity in the leaves of <i>Passiflora</i> spp. seedlings. In addition, the combined transcriptome and proteome analysis results showed that COS mainly acted on the Brassinosteroids (BRs) cell signaling pathway, one of plant hormone signal transduction pathway, in <i>Passiflora</i> spp., thus activating the up-regulated expression of <i>TCH4</i> and <i>CYCD3</i> genes to improve the resistance to CMV disease. Therefore, our study results demonstrated that COS could be used as a potential plant immune inducer to control the <i>Passiflora</i> spp. CMV disease in the future.Chitosan oligosaccharide as a plant immune inducer on the <i>Passiflora</i> spp. (passion fruit) CMV disease.Zhang Liqun L, Yu Lu L, Zhao Zhi Z, Li Pei P, Tan Shuming SfalseProteomics Study of Passion Fruit Treated by Spraying Disease resistant DrugsFruitOn the basis of transcriptional sequencing data, a protein sequence database was established. By extracting the leaf proteins of Passion Fruit seedlings after spraying, the differential proteins produced were identified by mass spectrometry, and GO and KEGG bioinformatics were used to analyze the key proteins and the key regulatory pathways, so as to clarify the mechanism of the key proteins after chemical treatment in their related metabolic pathways.Fri Dec 16 00:00:00 GMT 2022PXD0388817816836814757
