Anthrax disease of tea trees is a long-term challenge that cannot be avoided in green prevention and control of tea gardens. In May 2026, a study in Horticulture Research compared the resistant variety "Zijuan" with the susceptible variety "Longjing 43" and identified a defense mainline: after pathogen infection, the jasmonic acid signal is activated, and the transcription factor CsMYC2.1 regulates CsNOMT, promoting the accumulation of defense metabolite sakuranetin, which is mainly enriched in resistant materials. This does not mean that 'field diseases have been solved', but it provides new clues for resistance screening, molecular markers, and low input disease management.
