Abstract

Mycorrhiza is a symbiotic fungus which aids in nutrient uptake enhanced root development and plant growth of most vascular flowering plants. The mutual associations between plant roots and mycorrhiza are ubiquitous in terrestrial ecosystems throughout the world. Under natural conditions oil palm is often colonized by arbuscular mycorrhizal AM fungi. It was proposed that AM might mitigate Ganoderma infection which leads to basal stem rot BSR disease a serious disease in oil palm plantation. The most significant symptom of BSR disease is the rotting of basal stem which subsequently leads to the col1apse of the palm. In this study cDNA microarray analysis was used to examine the transcript profiles of oil palm roots during the development of AM symbiosis and upon Ganoderma infection. Besides the possibility of using AM as a biocontrol agent against BSR disease was also investigated. cDNA microarray was developed from 3 874 PCR amplified cDNAs of oil palm root vegetative meristem and zygotic embryo. Microarray analysis of mycorrhizal colonization and Ganoderma infection of oil palm may contribute towards better understanding and identification of genes relevant to these interactions.
