A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.
Establishing retinal contrast transmission as a novel determinant of mammalian fitness, this research adds functional significance to a prominent exception of nuclear organization, previously described in nocturnal rod photoreceptor cells.
Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.
Heterogeneity in perceptual sensitivity of human cone-mediated vision across wavelength originates in the cone photoreceptors, where S cones exhibit distinct functional properties in comparison to L and M cones.
A molecular atlas of the chick retina provides a comprehensive classification and characterization of 136 cell types, yielding novel insights into retinal structure, function, development, and evolution.
Nonlinear receptive field subunits in retinal ganglion cells are isolated and characterized by clustering spike-triggered stimuli, and validated on population responses to naturalistic and novel closed loop stimuli.
