Polar epicuticular lipids of Lycopersicon pennellii
Phytochemistry, 1987Abstract Trichome exudates of Lycopersicon pennellii yielded nine 2,3,4-tri-O-acylglucose esters as α- and β-anomers from the polar fraction of the epicuticular lipid mixture. The esters were primarily derived from 2-methylpropanoic, 2-methylbutanoic, 3-methylbutanoic, 8-methylnonanoic and n-decanoic acids, together with trace quantities of 10 ...

Inheritance of potato aphid resistance in hybrids between Lycopersicon esculentum and L. pennellii
Theoretical and Applied Genetics, 1989The potato aphid, Macrosiphum euphorbiae Thomas, is an important pest of tomato, Lycopersicon esculentum Mill., because it transmits tomato viruses and directly reduces crop yields by its feeding. This study was conducted to determine whether the wild tomato species, Lycopersicon pennellii (Corr.) D'Arcy, would be useful as a source of potato aphid ...

Settling of the potato aphid,Macrosiphum euphorbiae, on feeding membranes was deterred by methanolic leaf rinses ofLycopersicon pennellii, or of its F1 with tomato,L. esculentum. The active compounds in theL. pennellii rinsates were identified as 2,3,4-tri-O-acylglucoses bearing short to medium chain length fatty acids. These compounds are localized in

A genomic library of Lycopersicon pennellii in L. esculentum: A tool for fine mapping of genes
Euphytica, 1994The cultivated tomato contains only a small fraction of the genetic variation present in its wild relatives. In order to use the wild germplasm in tomato breeding and genetic studies we developed a new kind of genetic resource which is composed of 50 L. esculentum lines each containing a single introgression from the green fruited species L. pennellii (

Resistance mechanisms of 5 Lycopersicon pennellii (Corr.) D’Arcy accessions to Spodoptera littoralis (Boisduval) were compared with that of 2 commercial cultivars of L. Esculentum with the ultimate intent of using L. pennellii as a source of resistance to be incorporated into L. esculentum .

Regeneration of somatic hybrid plants formed between Lycopersicon esculentum and L. pennellii
Theoretical and Applied Genetics, 1987Somatic hybrid plants have been regenerated following polyethylene glycol mediated fusion of leaf mesophyll protoplasts from tomato and protoplasts from Lycopersicon pennellii callus. Three different cultivars of tomato were used as sources of protoplasts: Early Girl, Manapal, and UC82B.

This study was conducted to identify randomly amplified polymorphic DNA (RAPD) markers associated with quantitative trait loci (QTLs) conferring salt tolerance during germination in tomato. Germination response of an F2 population (2000 individuals) of a cross between UCT5 (Lycopersicon esculentum, salt-sensitive) and LA716 (L. pennellii, salt-tolerant)

Tomato is one of the major vegetable crops grown in diverse climatic conditions. To exploit hybrid vigour lines with high combing ability have been developed and successfully used to produce hybrid varieties. Tomato has a tremendous potential of heterosis for earliness, uniformity, total yield and resistance attributes and the main constraint for a ...

L. esculentum and L. pennellii are related species. The first is the cultivated tomato, and the second is a drought tolerant Peruvian weed. The two species were grown in 12 kg pots for 130 days and both biomass production, including roots, shoots and fruits, and transpiration were measured.
