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 ...

Divergent Mating Systems and Parental Conflict as a Barrier to Hybridization in Flowering Plants [PDF]

open access: yes, 2005
Parental conflicts can lead to antagonistic coevolution of the sexes and of parental genomes. Within a population, the resulting antagonistic effects should balance, but crosses between populations can reveal conflict.

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

Entrapment of two-spotted spider mite, Tetranychus urticae (Acari: Prostigmata: Tetranychidae), by type IV glandular trichomes of Lycopersicon species [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2012
Two-spotted spider mite (TSSM) is becoming resistant to many of the pesticides used in the tomatofields. A potential alternative method of control is host plant resistance, which may be mediated byglandular trichomes.

Oviposition and nymphal dispersion of Bemisia tabaci biotype B on tomato genotypes [PDF]

open access: yes, 2008
Diversos métodos têm sido empregados para avaliar a resistência de plantas a moscas-brancas. Todavia, poucos trabalhos têm sido realizados visando determinar a dispersão de ninfas desses insetos sobre as plantas.
