For Objective 1, necrotic tissues will be harvested from lethal yellows (LY) disease-affected palm trees and total DNA will be extracted from selected tissues. Microbial populations will be characterized using 454 pyrosequencing technology with primers designed to target V3 and V6 hypervariable regions of bacterial 16S rRNA genes. For Objective 2, total DNA will be extracted from symptomatic tissues of phytoplasma-infected plants, and phytoplasma DNA will be enriched through cesium chloride gradient centrifugation. Phytoplasma genome survey sequencing will be conducted using 454 pyrosequencing technology using coded primers. For both Objectives, the sequence data obtained will be analyzed and annotated using a suite of bioinformatic tools.
