Abstract
Basal stem rot BSR is the most serious disease in oil palm. In this study we profiled the transcripts in oil palm Elaeis guineensis Jacq. roots infected by Ganoderma boninense the causal agent of BSR at 3-9 week-post-infection wpi using cDNA microarray. Our findings revealed that J73 genes were differentially regulated in oil palm roots infected by G. boninensro compared to uninfected oil palm roots from 3 to 9 wpi. Among these genes were genes related to defense and stress which formed the largest functional category 13 . Other major functional categories of differentially expressed genes in G. boninense infected oil palms were genes related to gene regulation hormone and development transportation structural proteins metabolism and signal transduction. The up-regulated genes in infected oil palms included isoflavone reductase Cu /Zn super-oxide dismutase and hydroxyproline-rich glycoproteinfamily protein; whereas those that were down-regulated in infected oil palms included defensins mannose-binding lectin and thioredoxin peroxidase. We also examined the role of arbuscular mycorrhizal AM fungi in mitigating BSR by examining the global transcript profiles of oil palms inoculated with AM fungi and G. boninense simultaneously compared to oil palms inoculated with G. boninense or AM fungi alone. Our findings showed that the interaction between oil palm and symbiotic fungi together with pathogenic fungi was more complex than expected and could neither be explained by pairwise host plant-mycorrhizal interaction nor plants-pathogenic interaction. This information is essential for the development of new strategies for crop protection.
