Melon genome sequenced
A Spanish-led research consortium has completed sequencing the melon genome. The Melanomics project generated sequence data from seven melon varieties. It showed that the fruit’s 450 Mb genome contains some 27,400 protein-coding genes, of which relatively few (411), are involved in disease resistance. The data identified 89 genes involved in fruit ripening. Of these, 26 are concerned with carotenoid biosynthesis and accumulation. The remainder (63) are related to sugar accumulation and taste. These include 21 previously unknown genes.
