Leaf-color is an effective marker to identify the hybridization of rice. Leaf-color related genes function in chloroplast development and the photosynthetic pigment biosynthesis of higher plants. The ygl7 (yellow-green leaf 7) is a mutant with spontaneous yellow-green leaf phenotype across the whole lifespan but with no change to its yield traits. We cloned gene Ygl7 (Os03g59640) which encodes ...

Wrede and Rothhaas (1934) proposed a tripyrrylmethene structure for the red pigment extracted from Serratia marcescens. This structure was supported by Hubbard and Rimington (1950) because of the similarity in spectral properties between extracted pigment and a synthetic tripyrrylmethene compound. Recent investigations (Williams et al., 1956) have demonstrated that pigment identical in spectral...

The ecological importance and diversity of pico/nanoplanktonic algae remains poorly studied in marine waters, in part because many are tiny and without distinctive morphological features. Amongst green algae, Mamiellophyceae such as Micromonas or Bathycoccus are dominant in coastal waters while prasinophytes clade VII, yet not formerly described, appear to be major players in open oceanic water...

main thrust of investigations on phenol oxidases in Drosophila has T g u s e d on pigment production and thus on color mutants since the very early experiments of GRAUBARD (1933). However, the function of the phenol oxidases may prove to be equally, or more important in cuticle formation (see KARLSON and SEKERIS 1964, for proposed pathway in Diptera). The role played by phenol oxidases in the d...

Green nano pigments of Cr2O3 and CoCr2O4 were successfully prepared by polyol method followed by calcination at 770°C. The Cr2O3 and CoCr2O4 samples were characterized by X-ray diffraction XRD, scanning electron microscopy SEM, diffuse reflectance spectroscopy DRS, dynamic light scattering DLS, UV–Vis spectroscopy and CIE-Lab colorimetry methods. Dynamic light scattering analysis confirmed the f...
