The chemical and electronic structure of ultrathin molecular films of trimethylamine alane (TMAA), condensed in UHV at -100°C, have been studied in the solid state, using both X-ray and ultraviolet photoelectron spectroscopy. The results are analyzed with the help of quantum chemical calculations at the ab initio Hartree-Fock 6-31G * level. Based upon the good agreement between theory and...
A full-length cDNA clone of rice yellow mottle sobemovirus (RYMV) was synthesized and placed adjacent to a bacteriophageT7 RNA polymerase promoter sequence. Capped-RNA transcripts produced in vitro were infectious when mechanically inoculated onto rice plants (Oryza sativa L.). Individual full-length clones varied in their degree of infectivity but all were less infectious than native viral RNA. A...
