Reciprocal Metabolite Regulation in Shiraia-Associated Symbiosis

Caption

A “donut” plate assay was established to assess the interactions between host Shiraia sp. S9 and the bacterial isolates from the fruiting body. Rhodococcus sp. No. 3 induced hypocrellin A (HA) biosynthesis in its fungal host through volatile-mediated elicitation, prompting Shiraia to leverage photoactivated extracellular HA for generating antibacterial reactive oxygen species that suppressed bacterial competitors. Rhodococcus countered this oxidative assault by synthesizing protective carotenoid antioxidants.
