Soybean (Glycine max) cultivars adapted to high latitudes have a weakened or absent sensitivity to photoperiod. The purposes of this study were to determine the molecular basis for photoperiod insensitivity in various soybean accessions, focusing on the sequence diversity of the E4 (GmphyA2) gene, which encodes a phytochrome A (phyA) protein, and 118 its… (More)
Hemocyanins are large multi-subunit copper proteins that transport oxygen in many arthropods and molluscs. Comparison of the amino acid sequence data for seven different subunits of arthropod hemocyanins from crustaceans and chelicerates shows many highly conserved residues and extensive regions of near identity. This correspondence can be matched closely… (More)
Small doses of cycloheximide given at intervals (pulses) cause phase shifts of the circadian clock of Neurospora. The effects of this drug on the clock are mediated through its inhibition of protein synthesis, since two cycloheximide-resistant mutants whose 80S ribosomes are resistant to cycloheximide showed no phase shift after exposure to the durg.
