Journal ArticleDOI
An Elicitor of Plant Volatiles from Beet Armyworm Oral Secretion
Hans T. Alborn,Ted C. J. Turlings,Ted C. J. Turlings,Ted C. J. Turlings,T. H. Jones,T. H. Jones,T. H. Jones,G. Stenhagen,G. Stenhagen,G. Stenhagen,John H. Loughrin,John H. Loughrin,John H. Loughrin,James H. Tumlinson,James H. Tumlinson,James H. Tumlinson +15 more
TL;DR: The compound N -(17-hydroxylinolenoyl)-l-glutamine (named here volicitin) was isolated from oral secretions of beet armyworm caterpillars and induced the seedlings to emit volatile compounds that attract parasitic wasps and natural enemies of the herbivores.
Journal ArticleDOI
How caterpillar-damaged plants protect themselves by attracting parasitic wasps
Ted C. J. Turlings,John H. Loughrin,Philip J. McCall,U. S. R. Rose,W. J. Lewis,James H. Tumlinson +5 more
TL;DR: The studies on the phenomena of herbivore-induced emissions of volatiles in corn and cotton plants and studies conducted by others indicate that the clarity of the volatile signals is high, as they are unique for herbivor damage, produced in relatively large amounts, and easily distinguishable from background odors.
Journal ArticleDOI
Diurnal cycle of emission of induced volatile terpenoids by herbivore-injured cotton plant.
TL;DR: The diurnal pattern of emission of volatile terpenoids was determined by collecting and analyzing the volatile compounds emitted by cotton plants subjected to feeding damage by beet armyworm larvae in situ, and volatile emission was monitored continuously.
Journal ArticleDOI
Volatiles emitted by different cotton varieties damaged by feeding beet armyworm larvae.
TL;DR: Volatile compounds elicited by insect herbivore feeding damage in five cotton cultivars and one naturalized cotton variety were examined by allowing beet armyworm larvae to feed overnight on leaves and collecting volatiles from the plants in situ.
Journal ArticleDOI
Suppression of a P450 hydroxylase gene in plant trichome glands enhances natural-product-based aphid resistance
Erming Wang,Rui Wang,Rui Wang,Joseph DeParasis,John H. Loughrin,John H. Loughrin,Susheng Gan,George J. Wagner +7 more
TL;DR: The results demonstrate the feasibility of significantly modifying the natural-product chemical composition and aphid-interactive properties of gland exudates using metabolic engineering and have implications for molecular farming.
