The effects of various insecticides on the fluidity of mitochondrial membranes and cross-resistance were investigated in the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) using strains that were both resistant and susceptible to avermectin. The resistant strain of P. xylostella, AV-R, developed 1078-fold resistance to avermetins with a high level of cross-resistance to t...

The 2015 Nobel Prize in Physiology or Medicine is awarded with one half jointly to Dr. William C. Campbell and Professor Satoshi Ōmura for their discoveries concerning a novel therapy against infections caused by roundworm parasites and the other half to Professor Youyou Tu for her discoveries concerning a novel therapy against Malaria. Parasitic diseases have long plagued humankind and constit...

The role of GABA(B) receptors in sleep is still poorly understood. GHB (γ-hydroxybutyric acid) targets these receptors and is the only drug approved to treat the sleep disorder narcolepsy. GABA(B) receptors are obligate dimers comprised of the GABA(B2) subunit and either one of the two GABA(B1) subunit isoforms, GABA(B1a) and GABA(B1b). To better understand the role of GABA(B) receptors in slee...

The effects of dwarfing alleles (reduced height, Rht) in near isogenic lines on wheat grain quality are characterised in field experiments and related to effects on crop height, grain yield and GA-sensitivity. Alleles included those that conferred GA-insensitivity (Rht-B1b, Rht-B1c, Rht-D1b, Rht-D1c) as well as those that retained GA-sensitivity (rht(tall), Rht8, Rht8 + Ppd-D1a, Rht12). Full ch...

One of the most important characteristics of breeding modern, high-yielding, hexaploid bread wheat cultivars is the utilization of reduced height genes (Rht) or dwarfing genes, which reduces plant height and simultaneously increases adaptability and grain yield potential (Worland et al., 2001). The most frequently used height reducing genes with strong effect on plant height shortening are Rht-...
