Characterization and mapping of leaf rust resistance in four durum wheat cultivars.

Widening the genetic basis of leaf rust resistance is a primary objective of the global durum wheat breeding effort at the International Wheat and Maize Improvement Center (CIMMYT). Breeding programs in North America are following suit, especially after the emergence of new races of Puccinia triticina such as BBG/BP and BBBQD in Mexico and the United States, respectively. This study was conducted to characterize and map previously undescribed genes for leaf rust resistance in durum wheat and to develop reliable molecular markers for marker-assisted breeding.

High density mapping and haplotype analysis of the major stem-solidness locus SSt1 in durum and common wheat.

Breeding for solid-stemmed durum (Triticum turgidum L. var durum) and common wheat (Triticum aestivum L.) cultivars is one strategy to minimize yield losses caused by the wheat stem sawfly (Cephus cinctus Norton).

Long-term study of antibody response and injection-site effects of oil adjuvants in Atlantic halibut (Hippoglossus hippoglossus L).

Atlantic halibut were injected intraperitoneally with human gamma globulin suspended in either phosphate buffered saline, Freunds complete adjuvant or Montanide ISA711 to test the long-term effects of adjuvants. Every month for 12 months up to five animals from each group were sampled. The peritoneal cavity was examined and the adhesion level scored on an arbitrary scale.

The abp locus of Streptococcus uberis encodes a protein homologous to polar amino acid and opine binding proteins of gram-negative bacteria.

A gene locus abp was identified immediately upstream of the CAMP factor gene cfu in Streptococcus uberis. An open reading frame capable of coding for a 277-residue protein was identified. On the basis of sequence characteristics, the abp gene product is potentially a polar amino acid and opine binding component of an ATP-binding cassette type (ABC-type) transport system similar to those of Gram-negative bacteria.
