Temperature and Photoperiod Influence Trichome Density and Sesquiterpene Content of Lycopersicon hirsutum f. hirsutum [PDF]
Resistance to Colorado potato beetle in a clone of Lycopersicon hirsutum f. hirsutum L. is attributed to the presence of the sesquiterpene zingiberene in the type VI leaf trichomes; however, both day/night temperature regimen and photoperiod affect zingiberene content and trichome density.

TRICHOME-MEDIATED RESISTANCE TO ARTHROPODS IN LYCOPERSICON HIRSUTUM [PDF]
Breeding for resistance to insects and other arthropod pests in vegetables has been a difficult endeavor. Greater public awareness of health and environmental issues requires that we as horticultural scientists reexamine why breeding for resistance has been difficult.

PRODUCTION OF SOMATIC HYBRIDS BETWEEN LYCOPERSICON HIRSUTUM AND L. ESCULENTUM. [PDF]
Unilateral incompatibility has limited the direction of crossing between L. esculentum and L. hirsutum ; the latter can only serve as the pollen parent. In an attempt to introduce the L. hirsutum cytoplasm into

Genetic Control and Evolution of Sesquiterpene Biosynthesis in Lycopersicon esculentum and L. hirsutum [PDF]
Segregation analysis between Lysopersicon esculentum (cultivated tomato) and L. hirsutum (wild form) in conjunction with positional verification by using near-isogenic lines demonstrated that biosynthesis of two structurally different classes of sesquiterpenes in these species is controlled by loci on two different chromosomes. A locus on chromosome 6,

Efeito de aleloquímicos em tricomas foliares de tomateiro na repelência a ácaro (Tetranychus urticae Koch.) em genótipos com teores contrastantes de 2-tridecanona [PDF]
Com o objetivo de avaliar a ação de repelência a ácaro Tetranychus urticae Koch. em folíolos de tomateiro com altos teores do aleloquímico 2-tridecanona (2-TD) associado a tricomas glandulares, utilizaram-se linhagens avançadas 'TOM 600' e 'TOM 601 ...

Sensitivity of Altitudinal Ecotypes of the Wild Tomato Lycopersicon hirsutum to Chilling Injury [PDF]
The transition temperature of the leaf polar lipids and the critical temperature for chill-induced inhibition of photosynthesis was determined for three altitudinal ecotypes of the wild tomato Lycopersicon hirsutum. Photosynthesis was measured as CO(2)-dependent O(2) evolution at 25 degrees C after leaf slices were exposed to chilling temperatures for ...

The Cf-4 and Cf-9 Resistance Genes Against Cladosporium fulvum are Conserved in Wild Tomato Species
The Cf-4 and Cf-9 genes originate from the wild tomato species Lycopersicon hirsutum and L. pimpinellifolium and confer resistance to strains of the leaf mold fungus Cladosporium fulvum that secrete the Avr4 and Avr9 elicitor proteins, respectively ...
