he new study shows that a large block of genes from one species of wild tomato is present in domestic tomato, and has widespread, unexpected effects across the whole genome.
Maloof and colleagues studied the domestic tomato, Solanum lycopersicum, and wild relatives S. pennellii, S. habrochaites and S. pimpinellifolium. Comparison of the plants' genomes shows the effects of evolutionary bottlenecks, Maloof noted -- for example at the original domestication in South America, and later when tomato
