Abstract: The invention relates to methods and compositions for identifying and selecting maize plants with enhanced resistance to northern leaf blight. Maize plants generated by the methods of the invention are also a feature of the invention.
Abstract: This invention relates to polynucleotide sequences encoding genes that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the genes from corn lines carrying said genes into other corn lines that do not carry said genes, in order to make them resistant to Colletotrichum and resistant to stalk rot.
Abstract: Halogen-free flame retardant compositions comprising copolyetherester thermoplastic elastomers, melamine cyanurate and epoxy-containing compounds and cables and wires made from such flame retardant polymer composition provide good electrical insulation resistance during use.
Abstract: Compositions and methods useful in identifying and selecting maize plants with increased ear weight and yield are provided herein. The methods use molecular genetic markers to identify and/or select maize plants with increased ear weight and increased yield or to identify and counter-select maize plants with decreased ear weight and decreased yield.

Abstract: This invention relates to processes for selective removal of contaminants from effluent gases. A sulfur dioxide absorption/desorption process for selective removal and recovery of sulfur dioxide from effluent gases utilizes a buffered aqueous absorption solution comprising weak inorganic or organic acids or salts thereof, to selectively absorb sulfur dioxide from the effluent gas. Absorbed sulfur dioxide is subsequently stripped to regenerate the absorption solution and produce a sulfur dioxide-enriched gas. A process for simultaneous removal of sulfur dioxide and nitrogen oxides (NOx) from effluent gases and recovery of sulfur dioxide utilizes a buffered aqueous absorption solution including a metal chelate to absorb sulfur dioxide and NOx from the gas and subsequently reducing absorbed NOx to form nitrogen. A process to control sulfate salt contaminant concentration in the absorption solution involves partial crystallization and removal of sulfate salt crystals.
