Stomatal Response to Light of Solanum pennellii, Lycopersicon esculentum, and a Graft-induced Chimera [PDF]

open access: yesPlant Physiology, 1978
To learn how species differences in stomatal behavior are regulated, the response of epidermal and leaf diffusive resistance to light was investigated in Lycopersicon esculentum Mill., Solanum pennellii Corr., and a periclinal chimera having an S. pennellii epidermis and an L. esculentum mesophyll that was produced from a graft of the two species.

Inheritance and genetic mapping of resistance to Alternaria alternata f. sp. lycopersici in Lycopersicon pennellii [PDF]

open access: yesMolecular and General Genetics MGG, 1995
The fungal pathogen Alternaria alternata f. sp. lycopersici produces AAL-toxins that function as chemical determinants of the Alternaria stem canker disease in the tomato (Lycopersicon esculentum). In resistant cultivars, the disease is controlled by the Asc locus on chromosome 3.

Seleção para alto teor de acilaçúcares em genótipos de tomateiro e sua relação com a resistência ao ácaro vermelho (Tetranychus evansi) e à traça (Tuta absoluta) Selection towards high acylsugar levels in tomato genotypes and its relationship with resistance to spider mite (Tetranychus evansi) and to the South American pinworm (Tuta absoluta)

open access: yesCiência e Agrotecnologia, 2008
Uma das estratégias do melhoramento do tomateiro, no Brasil, visando à resistência a pragas, tem sido a utilização de aleloquímicos presentes nos folíolos.

Acylsugars of the wild tomato Lycopersicon pennellii in relation to geographic distribution of the species

open access: yesBiochemical Systematics and Ecology, 1994
Abstract Acylsugars exuded by glandular trichomes mediate insect resistance of the wild tomato Lycopersicon pennellii. Fifteen accessions of this species and four accessions of L. pennellii var. puberulum were surveyed for variability of acylsugar production.

Resistance of 14 accessions/cultivars of Lycopersicon spp. to two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), in laboratory and greenhouse [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2012
Fourteen accessions and cultivars of Lycopersicon spp. were studied to evaluate their resistance to two-spotted spider mite, Tetranychus urticae Koch, under laboratory and greenhouse conditions.

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.

QTL analysis of fruit antioxidants in tomato using Lycopersicon pennellii introgression lines

open access: yesTheoretical and Applied Genetics, 2005
Antioxidants present in fruits and vegetables may help prevent some chronic diseases such as cancer, arthritis, and heart disease. Tomatoes provide a major contribution to human dietary nutrition because of their widespread consumption in fresh and processed forms.

Alterations of the manifestations of hybrid breakdown in Lycopersicon esculentum L. pennellii F 2 populations containing L. esculentum versus L. pennellii cytoplasm [PDF]

open access: yesSexual Plant Reproduction, 1995
Reproductive abnormalities reduced the percent stainable pollen, and fruit and seed set in interspecific F2 populations derived from crosses of Lycopersicon esculentum and L. pennellii but were not observed in parental lines and interspecific F1 populations.

Herança de acilaçúcares em genótipos de tomateiro provenientes de cruzamento interespecífico Inheritance of tomato leaflet acylsugar contents in genotypes derived from an interspecific cross

open access: yesPesquisa Agropecuária Brasileira, 2007
O objetivo deste trabalho foi determinar a herança da produção de acilaçúcares em genótipos de tomateiro, em uma população segregante (F2) do terceiro retrocruzamento, para Lycopersicon esculentum Mill. 'TOM-584', a partir da espécie L. pennellii 'LA-716'
