While ethylene (ETH) promotes and 1-methylcyclopropene (1-MCP) inhibits mango peel coloration, the underlying molecular mechanisms remain incompletely understood. This study investigated the effects of ETH and 1-MCP on ‘Guifei’ mango, focusing on the regulation of the <em>MiPAL1</em> promoter by MiERF5 and MiMYB7. ETH enhanced the activities of anthocyanin biosynthesis enzymes (PAL, CHI, ANS, DFR, UFGT) and anthocyanin accumulation, whereas 1-MCP suppressed these processes. ETH upregulated <em>MiPAL1</em> and <em>MiERF5</em>, while 1-MCP increased <em>MiMYB7</em> expression. Nuclear-localized MiERF5 directly bound and activated the <em>MiPAL1</em> promoter (verified by Y1H and DLR assays), whereas MiMYB7 repressed it. Crucially, Y2H, BiFC, and LCI assays revealed that a MiERF5-MiMYB7 protein complex binds to <em>MiPAL1</em>, alleviating MiMYB7-mediated repression. Functional validation in mango discs demonstrated that <em>MiMYB7</em> overexpression inhibited coloration by downregulating <em>MiPAL1</em>, whereas <em>MiERF5</em> overexpression or co-expression of <em>MiERF5</em> + <em>MiMYB7</em> activated <em>MiPAL1</em> and anthocyanin synthesis.

Complete inhibition of mycelial growth was observed following plasma exposure for up to seven days. Direct NTP treatments significantly reduced spore viability, with helium plasma achieving 18.53–49.00 % inactivation and argon plasma achieving 13.15–47.21 % based on spore counts. The highest reduction in viable colony counts (up to 97.34 %) was observed following 10 min of argon plasma exposure at a flow rate of 0.25 Lpm. PAW treatments also significantly reduced spore viability, with argon-based PAW showing greater antifungal activity (35.56–53.77 %) than helium-based PAW (19.44–41.39 %). At a flow rate of 0.25 Lpm and an exposure time of 10 min, PAW generated using argon and helium resulted in reductions in viable colony counts of 64.77 % and 72.35 %, respectively. Membrane integrity assays revealed increased leakage of UV-absorbing intracellular components, while fluorescence-based viability staining confirmed reduced spore viability following both treatments. Scanning electron microscopy further revealed spore surface deformation consistent with oxidative damage. In vivo assays on detached Nam Dok Mai and Chok Anan mangoes demonstrated significant suppression of anthracnose lesion development from both mycelia and spore inoculations, particularly during the later stages of incubation.

Firstly, cluster analysis was performed on the SSC, and the R² statistic and the elbow rule were introduced to determine the optimal number of clusters. The training set and test set were divided using the Monte Carlo random sampling method. Subsequently, the training set was augmented by incorporating spectral data that had undergone moving average smoothing, thereby forming an enhanced sample set. Furthermore, the probability mass and error rate of training set samples were integrated to formulate the sample weight coefficient. At last, the augmented training set was employed to establish a classification model via a three-layer neural network.
