TRICHOME-MEDIATED RESISTANCE TO ARTHROPODS IN LYCOPERSICON HIRSUTUM [PDF]

open access: yesHortScience, 1990
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.

Genetic Control and Evolution of Sesquiterpene Biosynthesis in Lycopersicon esculentum and L. hirsutum [PDF]

open access: yesThe Plant Cell, 2000
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,

Sensitivity of Altitudinal Ecotypes of the Wild Tomato Lycopersicon hirsutum to Chilling Injury [PDF]

open access: yesPlant Physiology, 1989
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

open access: yesMolecular Plant-Microbe Interactions, 2005
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 ...

PRODUCTION OF SOMATIC HYBRIDS BETWEEN LYCOPERSICON HIRSUTUM AND L. ESCULENTUM. [PDF]

open access: yesHortScience, 1991
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
