Biochemical Genetics of Plant Secondary Metabolites in Arabidopsis thaliana: The Glucosinolates.
A pathway for the biosynthesis of glucosinolates in A. thaliana is proposed following experiments involving feeding of (14)C-labeled intermediates which suggested that the gsm1 allele results in a metabolic block which decreases the availability of several amino acid substrates required for glucosInolate biosynthesis.
Fatty acid elongation in developing seeds of Arabidopsis thaliana
Six mutants of Arabidopsis thaliana (L.) Heynh., with reduced levels of very long chain fatty acids (VLCFAs) in their seed lipids, were isolated by direct screening of ethyl methane
HPLC Separation of Glucosinolates from Leaves and Seeds of Arabidopsis thaliana and Their Identification Using Thermospray Liquid Chramatography/Mass Spectrometry
Leaf and seed extracts of Arabidopsis thaliana var. Columbia contain a large number of glucosinolates, representing close to 2 5 % of those known to occur in nature. The glucosinolates, in the form
Biosynthesis of glucosinolates.
Field trapping of diamondback mothPlutella xylostella using an improved four-component sex attractant blend
Replacement of (Z)-9-tetradecenyl acetate in the four component lure with (Z-9-TetradeCen-1-ol, at the level of 10% of the total lure mixture, did not alter its attractancy for diamondback males, but it did inhibit attraction ofCrymodes devastator.
Attraction of the diamondback moth (Lepidoptera: Plutellidae) to volatiles of Oriental mustard: the influence of age, sex, and prior exposure to mates and host plants.
A Y-tube behavioral bioassay was developed to investigate attraction of the diamondback moth, Plutella xylostella (L.), to volatiles from host plants, and the patterns of response are interpreted in relation to reproduction in this species.
Identification of chemical imposition stimulants for the diamondback moth, Plutella xylostella, present in three species of Brassicaceae
It is demonstrated that the moths do not discriminate between glucosinolates with different side‐chain structures, and in tests using allylglucosinolate the oviposition response was dose‐dependent, and one of the species tested, S. alba, contained a possible Oviposition deterrent.
Biosynthesis of Acyl Lipids Containing Very-Long Chain Fatty Acids in Microspore-Derived and Zygotic Embryos of Brassica napus L. cv Reston.
The biosynthesis of VLCFAs and their incorporation into glycerolipids in vitro in the MD embryo system occurred at rates comparable to those measured in developing zygotic Reston embryos at about 20 days postanthesis and the incorporation of newly synthesized V LCFAs into TAGs via the Kennedy pathway was demonstrated.
Daily Patterns of Reproductive Activity and the Influence of Adult Density and Exposure to Host Plants on Reproduction in the Diamondback Moth (Lepidoptera: Plutellidae)
Daily patterns of activity and the effects of adult density and exposure to host plants on the onset of reproductive activities and age-specific fecundity of the diamondback moth, Plutella xylostella
