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 ...

Feeding behavior of the green peach aphid, Myzus persicae (Sulzer), differed on Lycopersicon pennelli (Corell) D Arcy (LA 716) and ‘VFT Vendor’ tomato ( L. esculentum [Mill.]). Fewer aphids initiated feeding on L. pennellii (LA 716), and time to first probe was significantly greater. Also, percentage of time spent probing and number of probes were less

Lycopersicon esculentum lines containing small overlapping introgressions from L. pennellii
Theoretical and Applied Genetics, 1992The objective of this project was to introgress small overlapping chromosome segments which cover the genome of L. pennellii into Lycopersicon esculentum lines. The interspecific hybrid was backcrossed to L. esculentum, and a map of 981 cM, based on 146 molecular markers covering the entire genome, was produced.

Somatic hybridization between Lycopersicon esculentum and Lycopersicon pennellii
Theoretical and Applied Genetics, 1985Selection and screening methods were devised which resulted in the identification of a number of somatic hybrid callus clones following fusion of Lycopersicon esculentum protoplasts and L. pennellii suspension culture protoplasts. Visual selection for callus morphology combined with a high fusion frequency and irradiation of one parental protoplast ...

A genomic library of Lycopersicon pennellii in L. esculentum: A tool for fine mapping of genes
Euphytica, 2004The 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 (

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

Acylsugars exuded from type IV trichomes mediate the multiple pest resistance found in the wild tomato species, Lycopersicon pennellii. A marker-assisted selection breeding program was used to attempt the transfer of the ability to accumulate acylsugars to cultivated tomato.

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 .

Acylsugars, the primary components of the exudate secreted by type IV trichomes of Lycopersicon pennellii (Carr.) D'Arcy LA716, mediate the resistance of this accession to silverleaf whitefly, Bemisia argentifolii Bellows & Perring, n. sp. Reduction in the settling of the adult silverleaf whiteflies correlates with the concomitant increase in applied ...
