Diversity of bacterial communities in diseased tissues of Naematelia sinensis

The MOCK group (healthy control) consisted of fully developed N. sinensis fruiting bodies with evenly distributed mycelia, randomly sampled from disease-free bags The HAF group included transitional tissue excised 2 cm from the periphery of Trichoderma infection sites, which exhibited no visible symptoms . The DiR group consisted of tissue samples precisely extracted from the central browning zone, characterized by a dark brown discoloration and soft, decayed texture, serving as representative diseased specimens . All samples (n = 3 per group) were collected from standardized cultivation bags within the same production batch to ensure consistency.
