Autor: Peter Morand, John T. Arnason, C. W. Berg, Bernard J. R. Philogène, F. Duval

Publikováno v: Journal of Chemical Ecology. 12:893-898

The botanical phototoxin, α-terthienyl (α-T) was spray applied to natural or artificial pools containing mosquito (Aedes intrudens) larvae and nontarget invertebrates (caddisfly, damselfly, midge, shrimp,Daphnia, snail) and one vertebrate (trout) a

Naturally occurring and synthetic analogues and derivatives of polyacetylenes and thiophenes of the Asteraceae were investigated for their phototoxic effects on mosquito larvae, iodination, dimethylation in the 3′,4′-position or substitution of t

Synthesis and evaluation of the naturally occurring phototoxin, alpha-terthienyl, as a control agent for larvae of Aedes intrudens, Aedes atropalpus (Diptera: Culicidae) and Simulium verecundum (Diptera: Simuliidae)

New methods to synthesize alpha-terthienyl ( α-T ) on a large scale have permitted field and laboratory evaluation of this naturally occurring phototoxin from plants for blackfly and mosquito control. The acute toxicity of α-T to blackfly larvae (

Polygalacturonase-Inhibiting Proteins Can Function as Activators of Polygalacturonase

Autor: G. Kemp, L. Stanton, C. W. Bergmann, R. P. Clay, P. Albersheim, A. Darvill

Publikováno v: Molecular Plant-Microbe Interactions, Vol 17, Iss 8, Pp 888-894 (2004)

The interaction between fungal endopolygalacturonases (EPGs) and polygalacturonase-inhibiting proteins (PGIPs) found in plant cell walls has been well established. The typical EPG/PGIP interaction is characterized by high affinity, reversibility, and

Fungal Polygalacturonases Exhibit Different Substrate Degradation Patterns and Differ in Their Susceptibilities to Polygalacturonase-Inhibiting Proteins

Autor: B. J. Cook, R. P. Clay, C. W. Bergmann, P. Albersheim, A. G. Darvill

Publikováno v: Molecular Plant-Microbe Interactions, Vol 12, Iss 8, Pp 703-711 (1999)

Polygalacturonic acid (PGA) was hydrolyzed by polygalacturonases (PGs) purified from six fungi. The oligogalacturonide products were analyzed by HPAEC-PAD (high performance anion exchange chromatography-pulsed amperimetric detection) to assess their
