Intermediate wheatgrass (Thinopyrum intermedium; IWG) is a perennial grass under development as grain and forage crop. Although IWG known for its ability to take up nitrate improve water quality, seasonal nitrogen (N) demand uptake by not well known. We measured shoot, root, production, tissue N concentration, soil mineral at multiple plant growth stages in 1- 2-year-old stands fertilized with ...

The green alga Chlorogonium elongatum, a member of the Volvocales, possesses a crystalline cell wall composed of hydroxyproline-rich glycoprotein similar to the primary cell wall glycoproteins of higher plants. Electron microscopy and computer image processing have been used to determine the crystal structure of the Chlorogonium cell wall in three dimensions to a resolution of 2.0 nm. The struc...

Intermediate wheatgrass (Thinopyrum intermedium (Host) Barkworth & D.R. Dewey; IWG) is a perennial sod-forming grass undergoing domesticated for use as dual-use grain and forage crop with potential environmental benefits. IWG plant populations increase stand age, which has been associated reductions in yields after the second production year, thus management techniques are needed to maintai...

Endophytic nitrogen fixing bacteria were isolated from the leaves, stems and roots of industrial variety (cv. U-Thong 3; UT3), wild and chewing sugarcane plants grown for 6 weeks in nitrogen (N)-free sand. Eighty nine isolates of endophytic bacteria were obtained on N-free agar. An acetylene reduction assay (ARA) detected nitrogenase activity in all 89 isolates. Three isolates from the chewing ...
