| 摘要 | Ceriporia species are well-known saprotrophic fungi that cause wood decay in the forest. Although some endophytic Ceriporia spp. have been isolated from living plants, none of them was considered a pathogen. However, a weakly grown tree of Delonix regia with the white resupinate basidiocarps of Ceriporia lacerata (syn. Irpex laceratus) covered on its roots and stem base suddenly toppled over in October 2021 at the campus of National Taiwan University. C. lacerata was isolated from the interior white rot wood tissues and confirmed for its identity using multi-locus phylogenetic analysis based on ITS, 28S, rpb1, rpb2 and tef1 genes. To investigate the pathogenicity of C. lacerata, wounded and nonwounded inoculations were conducted on the stem of 1-m-high D. regia seedlings. Although none of the infected plants showed visible symptoms within 122 days post inoculation, C. lacerate caused browning of the interior wood at the inoculation site, and C. lacerata re-isolated at the frequency of 80% from the bark and 25% from the wood tissues. The results indicated that C. lacerata is able to infect living woody plants and caused wood degradation. Considering that C. lacerata is a potential tree pathogen, the inhibitory effects of 13 fungicides with 9 modes of action were evaluated on the mycelial growth of C. lacerata, and tebuconazole and propiconazole were the most effective. How C. lacerata affects the health of living plants and its management are worthy of further investigation. |
