    Screening of rice mutants with improved saccharification efficiency results in the identification of CONSTITUTIVE PHOTOMORPHOGENIC 1 and GOLD HULL AND INTERNODE 1

    The screening of rice mutants with improved cellulose to glucose saccharification efficiency (SE) identifies reduced xylan and/or ferulic acid, and a qualitative change of lignin to impact SE. ...

    ROOT GROWTH INHIBITING, a Rice Endo-1,4-β-d-Glucanase, Regulates Cell Wall Loosening and is Essential for Root Elongation

    The molecular mechanism involved in cell wall dynamics has not been well clarified, although it is quite important for organ growth. We characterized a rice mutant, root growth inhibiting (rt), which is defective...

    OsCAD2 is the major CAD gene responsible for monolignol biosynthesis in rice culm

    Cinnamyl alcohol dehydrogenase (CAD) catalyzes the last step of monolignol biosynthesis. The rice genome contains 12 CAD-like genes, and whereas the proteins encoded by OsCAD2 and OsCAD7 are known to function in ...

    Gain of deleterious function causes an autoimmune response and Bateson–Dobzhansky–Muller incompatibility in rice

    Reproductive isolation plays an important role in speciation as it restricts gene flow and accelerates genetic divergence between formerly interbreeding population. In rice, hybrid breakdown is a common reprod...

    Interaction of two recessive genes, hbd2 and hbd3, induces hybrid breakdown in rice

    Reproductive barriers are important for the maintenance of species identity. We discovered a reproductive barrier via hybrid breakdown among the progeny of a cross between the japonica rice cultivar Koshihikari a...

    Erect leaves caused by brassinosteroid deficiency increase biomass production and grain yield in rice

    New cultivars with very erect leaves, which increase light capture for photosynthesis and nitrogen storage for grain filling, may have increased grain yields1. Here we show that the erect leaf phenotype of a rice...

    Genetic manipulation of gibberellin metabolism in transgenic rice

    The 'green revolution' was fueled by the introduction of the semi-dwarf trait into cereal crop cultivars. The semi-dwarf cultivars—which respond abnormally to the plant growth hormone gibberellin (GA)—are more...
