Daphnia pulex: A Genome for the Environment
Scientists have studied Daphnia for centuries because of its importance in aquatic food
webs and for its transformational responses to environmental stress. Predators signal some of the
animals to produce exaggerated spines, neck-teeth or helmets in self-defense. And like the virgin
nymph of Greek mythology that shares its name, Daphnia thrives in the absence of males --
by clonal reproduction, until harsh environmental conditions favor the benefits of sex.
In early February 2011, the Daphnia Genomics Consortium, of which the
CGB is a co-founder, released its manuscripts on the genome of Daphnia pulex. This tiny
crustacean appears to have 31,000 genes -- more than the estimated 23,000 in humans. In light of the findings
from these genomic analyses, Daphnia emerges now as a model organism for the new field of Environmental Genomics.

Lizard Genomics
The genome sequence of the North American green anole lizard was published in Nature in Sept 2011. The work, which reveals the first reptile genome sequence, could be important for understanding the evolution of the amniotic egg and of vertebrate evolution more generally. Under contract from the Broad Institute, the CGB created the cDNA resources used to discover and characterize the transcripts of genes expressed under various conditions. The sequences produced by these resources help determine the structures of Anolis genes, including alternative transcripts.
