The retention of D genome wheat alleles in the progeny of imidazolinoneresistant wheat (R-wheat) and jointed goatgrass hybrids backcrossed to jointed goatgrass was documented in this study. Resistance to the imazamox application was used as a marker for the imidazolinone-resistance gene. Fourteen simple sequence repeat (SSR) markers, for the wheat...
Bioremediation in the vadose zone is unpredictable because of poor understanding of factors influencing microbial growth in this environment. A lab-scale experimental system was developed to examine, noninvasively, interactions between microbial growth, water flow, and solute transport in unsaturated porous media. Measurements of microbial colonization, and its impact on hydrology,...
