Atoh7-independent specification of retinal ganglion cell identity.

Retinal ganglion cells (RGCs) relay visual information from the eye to the brain. RGCs are the first cell type generated during retinal neurogenesis. Loss of function of the transcription factor , expressed in multipotent early neurogenic retinal progenitors leads to a selective and essentially complete loss of RGCs.

Characterization of complementary chromatic adaptation in Gloeotrichia UTEX 583 and identification of a transposon-like insertion in the cpeBA operon.

Many cyanobacteria are able to alter the pigment composition of the phycobilisome in a process called complementary chromatic adaptation (CCA). The regulatory mechanisms of CCA have been identified in Fremyella diplosiphon, which regulates both phycoerythrin and phycocyanin levels, and Nostoc punctiforme, which regulates only phycoerythrin production. Recent studies show that these species use different regulatory proteins for CCA.
