Allelopathy and underlying mechanism of mango (<i>Mangifera indica</i>) peel extracts on <i>Alexandrium catenella</i>.

ABSTRACT: Harmful algal blooms (HABs) have always been a worldwide environmental issue. The methods based on the principle of allelopathy provide a novel direction for controlling HABs; however, there are a few studies on the application of allelopathic algaecides to control harmful algae in marine environments. Here we examined the algicidal capacity of 15 fruit peel extracts with biological activity on Alexandrium catenella. The results displayed that the mango peel extracts (MPE) showed efficient inhibition on species growth. The algicidal rate reached 93.32 ± 0.56% at 96 h after adding 5 g/L MPE to the culture medium of A. catenella. Furthermore, we found that the expression of key genes involved in PSII and PSI was downregulated as well as obstructed the electron transportation in
