Ceratocystis manginecans associated with a serious wilt disease of two native legume trees in Oman and Pakistan
Australasian Plant Pathology 42 (2), 179-193
Abstract: A serious wilt disease has recently been found on Prosopis cineraria (Ghaf) in Oman and on Dalbergia sissoo (Shisham) in Pakistan. Disease symptoms on both these native, leguminous hosts include vascular discolouration and partial or complete wilt of affected trees. A species of Ceratocystis was consistently isolated from symptomatic material. Morphological comparisons and analyses of DNA sequence data of the ITS, β-tubulin, and EF 1-α gene regions showed that the Ceratocystis isolates obtained from both tree species represent C. manginecans. This is the same pathogen that is causing the devastating mango sudden decline disease in Oman and Pakistan. This is also the same pathogen that has been reported causing a wilting disease on Acacia mangium in Indonesia. Cross inoculation with C. manginecans isolates from P. cineraria, D. sissoo and mango showed that the fungus can cause disease on all three trees.
