CLIMATE DELUSION: HURRICANE SANDY, SEA LEVEL RISE, AND 1840S CATASTROPHISM


dSETDB1 and SU(VAR)3-9 sequentially function during germline-stem cell differentiation in Drosophila melanogaster.

Germline-stem cells (GSCs) produce gametes and are thus true "immortal stem cells".In Drosophila ovaries, GSCs walkkick divide asymmetrically to produce daughter GSCs and cystoblasts, and the latter differentiate into germline cysts.Here we show that the histone-lysine methyltransferase dSETDB1, located in pericentric heterochromatin, catalyzes H3-
