Resistance to Phytophthora infestans in Lycopersicon pennellii [PDF]

Plant Disease, 2007
To determine if the desert tomato, Lycopersicon pennellii, possesses resistance to late blight, caused by Phytophthora infestans, two plant populations were analyzed. Resistance was identified through assessments of disease progress in an F2 mapping population (L. esculentum × L. pennellii) and in a series of introgression lines (L.

Improvement of regeneration of Lycopersicon pennellii protoplasts by decreasing ethylene production [PDF]

Plant Cell Reports, 1991
Lycopersicon pennellii shoots, cultured in vitro for more than a year (type I plants) produced few viable protoplasts in contrast to shoots cultured in vitro for less than five months (type II plants). Ethylene production of both plant types was compared.

SOIL-BORNE FUNGAL RESISTANCE IN LYCOPERSICON PENNELLII ACCESSIONS. [PDF]

HortScience, 1990
Forty-two Lycopersicon pennellii Corr. D'Arcy accessions, from the Tomato Genetics Stock Center, were inoculated for resistance to Fusarium wilt race 3 at the 3-leaf and cotyledon stage. All were over 90% healthy when inoculated at the 3-leaf stage but had greater disease incidence at the cotyledon stage.

Unilateral incompatibility as a major cause of skewed segregation in the cross between Lycopersicon esculentum and L. pennellii [PDF]

Plant Cell Reports, 1996
Skewed segregations are frequent events in segregating populations derived from different interspecific crosses in tomato. To determine a basis for skewed segregations in the progeny of the cross between Lycopersicon esculentum and L.

Mediterranean Tomato Landraces Exhibit Genotype-Specific Transcriptomic Responses to Water Stress. [PDF]

Physiol Plant
ABSTRACT Drought stress is a critical limitation to crop production, particularly in Mediterranean climates. The molecular response of drought adaptation in crops is variable and coordinated in leaves and roots. To understand the molecular basis of drought tolerance in tomato, the transcriptomic responses of two drought‐tolerant Mediterranean landraces

Epicuticular Lipid Accumulation on the Leaves of Lycopersicon pennellii (Corr.) D'Arcy and Lycopersicon esculentum Mill [PDF]

Plant Physiology, 1985
A comparison was made of epicuticular lipid accumulation on leaves of Lycopersicon pennellii and Lycopersicon esculentum Mill. cv VF36 from 5 to 16 weeks of age. Epicuticular lipids were a small fraction of the leaf dry weight (0.16%) of 5-week-old ;VF36', and increased to only 0.96% of the leaf dry weight after an additional 12 weeks of growth.

Inheritance of Glandular Trichomes in Crosses between Lycopersicon esculentum and Lycopersicon pennellii

Journal of the American Society for Horticultural Science, 1984
Abstract The absence or presence of type IV trichomes seemed to be simply inherited in crosses of the tomato, Lycopersicon esculentum Mill , and Lycopersicon pennellii Correll. F 2 and BC

Branched Chain Amino Acid Metabolism in the Biosynthesis of Lycopersicon pennellii Glucose Esters [PDF]

Plant Physiology, 1990
Lycopersicon pennellii Corr. (D'Arcy) an insect-resistant, wild tomato possesses high densities of glandular trichomes which exude a mixture of 2,3,4-tri-O-acylated glucose esters that function as a physical impediment and feeding deterrent to small arthropod pests.

heterose e capacidade combinatória de linhagens de tomateiro ricas em acilaçúcares Heterosis and combining ability of acylsugar-rich tomato lines

Ciência e Agrotecnologia, 2010
Com o presente trabalho, objetivou-se estimar a capacidade combinatória de linhagens de tomate ricas em acilaçúcares (AA) quando cruzadas com linhagens com baixo teor de acilaçúcares e estudar a expressão da heterose nos híbridos obtidos.
