    “…A novel method for the metal-free synthesis of amides from thioamides based on visible-light photoredox catalysis and in an air atmosphere is reported. Natural pigment chlorophyll is used as a photosensitizer to generate singlet molecular oxygen (1)O(2), which is involved in the aerobic desulfurization of thioamides. …”

    “…In this study, by exploring ethyl methanesulfonate (EMS)-mediated mutagenesis in Chenopodium quinoa NL-6 variety, we identified a mutant nl6-35 that displays faded green leaf and reduced chlorophyll (Chl) and carotenoid contents. Bulk segregant analysis (BSA) revealed that a mutation in CqPORB gene is genetically associated with the faded green leaf of the nl6-35 mutant. …”
