SÃO PAOLO--Brazil has announced plans to create a network of laboratories, the Organization for Nucleotide Sequencing and Analysis, here to sequence the complete genome of the bacterium Xylella fastidiosa, which causes a number of plant diseases, particularly those that threaten Brazil's important citrus industry. One of the laboratories will be specifically devoted to bioinformatics. There will also be two large laboratories to generate sequence data and act as training and support centers for the rest of the network.
