“A limited backcross procedure was utilized to introgress genes associated with grain quality traits from Oryza rufipogon (Accession No. IRGC 105491), a wild rice from Malaysia, to the cultivated rice O. sativa cv. MR219, a popular high yielding Malaysian rice cultivar. A set of 10 BC2F7 progenies were selected based on the field performance and phenotypic appearance in BC2F5 and BC2F6 generations, AG-881 which initially started with 266 progenies in the BC2F2 generation. These 10 advanced breeding lines are similar to each other but differ in several important grain quality traits, which can be traced to O. rufipogon introgressions. Phenotyping and genotyping of BC2F7 variants were considered for QTL analysis. The introgressed lines did not show any significant changes compared to the recurrent parent MR219 for the traits grain density and milled rice percentage. All 10 progenies showed significantly higher head rice percentages (70-88%) than
the recurrent parent MR219. Variants G13 and G15 had higher amylose contents than MR219. All variants were analyzed using polymorphic SSR markers. Of the GSK2879552 ic50 34 SSR markers, only 18 showed introgression from O. rufipogon for selleck chromosomes 1, 2, 3, 5, 6, 8, 10, and 11. Graphical genotypes were prepared for each variant, and association between the introgression regions and the traits that increased grain quality was visualized. Based
on marker trait association, some of the QTLs are stable across environments and genetic backgrounds and could be used universally.”
“We demonstrate active voltage-controlled spectral tuning of mid-infrared plasmonic structures. Extraordinary optical transmission gratings were fabricated on n-doped GaAs epilayers with a HfO(2) gate dielectric between the grating and the doped semiconductor. The permittivity of the GaAs was tuned by depleting charge carriers below the top grating gate upon the application of a reverse bias to the gate. Devices were characterized both electrically and optically, and resonant transmission peak spectral and transmitted intensity shifts were achieved. Possible applications for, as well as the limitations of, the demonstrated technology are discussed. (C) 2011 American Institute of Physics. [doi:10.1063/1.3600230]“
“Background: Safety of a sixth consecutive dose of acellular pertussis vaccine in adolescents was assessed in a 2-armed, randomized study.
Methods: Adolescents who had received 5 doses of acellular pertussis vaccine combined with diphtheria and tetanus toxoids (6-dose group) received 1 dose of reduced 5-component acellular pertussis vaccine combined with tetanus toxoid and reduced diphtheria toxoid (Tdap).
