Abstract
The discoloration problem of rubber wood caused by the discoloration fungi has caused the degradation of rubber wood and greatly reduced its economic value, and the prevention and control of rubber wood discoloration have become the top priority of basic research on rubber wood protection and modification. To determine the fungal community diversity and dominant groups before and after discoloration of rubber wood, nine rubber wood samples were subjected to ITS sequencing using Illumina high-throughput sequencing technology. The results showed that the detected fungal communities comprised 5 phyla, 18 classes, 58 orders, 137 families, 218 genera, and 297 species. Discoloration of rubber wood is not caused by a single species, with the dominant genera for discolored rubber wood being Huntiella, Ceratocystis, and Acremonium and for undiscolored rubber wood, Phomopsis. Furthermore, the diversity, uniformity of species distribution, and richness of discolored rubber wood were found to be higher than those of undiscolored rubber wood. In conclusion, understanding the change trends in the structure of these fungal communities is essential for studying the biological control of rubberwood discoloration.
