The aims of present works were to explore the difference in pulp breakdown of ‘Fuyan’ and ‘Dongbi’ longans and its relationship with cell wall metabolism. Comparison with ‘Fuyan’ longan fruit, postharvest ‘Dongbi’ longan fruit showed lower pulp breakdown index, lower activities of PE, PG, cellulase, β-Gal, XET, and lower expression levels of their corresponding genes. In addition, higher levels of cell wall polysaccharides including ISP, CSP, cellulose and hemicellulose were exhibited in ‘Dongbi’ longan pulp. These findings implied that, the reduced activities of enzymes and the down-regulated expressions of genes-involved in cell wall disassembly were shown in ‘Dongbi’ longan pulp, which might reduce the dissolution of polysaccharides and maintain a higher structural integrity in ‘Dongbi’ longan pulp cell wall, and consequently the mitigated pulp breakdown was displayed in ‘Dongbi’ longan during storage.
