Scanning electron microscopy investigation of epizootic lobster shell disease in Homarus americanus.

actin (2 forms) occurred 80 times (19%) and myosin (11 forms) was found 68 times (16%). The remaining ESTs could be classified as being involved in gene/protein expression (3%), immunity (7%), metabolism (31%), protein binding (7%), or cell signaling (8%) (Fig. 1). Some identified genes (11%) could not be classified into any of these groups. The sequences of all the ESTs generated from the bay scallop cDNA library and the putative identifications determined to date are available on a Bay Scallop EST project website (http://www. mbl.edu/goetz/EST.html) as well as in NCBI’s GenBank database (http://www.ncbi.nlm.nih.gov/) [GenBank Accession numbers CF197421-CF197787]. The ESTs generated offer a valuable resource to scientists in a wide range of disciplines including muscle physiology, growth and development, immunity, genetic identification, and aquaculture. Funding for this research was provided by USDA grant #200203633—Program in Growth and Nutrient Utilization.
