Enhancing loquat fruit quality with methyl jasmonate: A study on sugar metabolism and gene expression dynamics

A research team investigated the dynamics of soluble sugars in "Zaozhong 6" loquat fruits following treatment with methyl jasmonate (MeJA). Their findings revealed that MeJA accelerates sugar accumulation and increases the sugar-acid ratio in fully ripe loquats, significantly enhancing fruit quality. This study also delved into the molecular mechanisms regulating sugar metabolism, noting significant changes in the expression of key genes such as FK, HK, SPP, SPS, and SS.
