NaCl tolerance in Lycopersicon pennellii introgression lines: QTL related to physiological responses [PDF]

Biologia Plantarum, 2011
The growth and ion content of salt sensitive Lycopersicon esculentum Mill. cv. M82 and salt tolerant L. pennellii Correll accession LA716 were examined under both control and stress conditions (150 mM NaCl). L.

Response of the tomato leaf miner Phthorimaea absoluta to wild and domesticated tomato genotypes. [PDF]

Pest Manag Sci
We evaluated oviposition and larval performance of P. absoluta on 19 tomato genotypes as an element of integrated pest management. Two wild tomatoes and a domesticated one showed resistance against the pest. Abstract BACKGROUND Phthorimaea absoluta, a highly destructive invasive pest, poses a significant threat to tomato production globally.

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

Quantitative trait locus analysis of leaf dissection in tomato using Lycopersicon pennellii segmental introgression lines. [PDF]

Genetics, 2003
Abstract Leaves are one of the most conspicuous and important organs of all seed plants. A fundamental source of morphological diversity in leaves is the degree to which the leaf is dissected by lobes and leaflets. We used publicly available segmental introgression lines to describe the quantitative trait loci (QTL) controlling the ...

Molecular breeding of tomato: Advances and challenges. [PDF]

J Integr Plant Biol
This review explores the evolution of tomato (Solanum lycopersicum) from its Andean origins to a globally cultivated crop, highlighting advancements in molecular breeding. It covers genome sequencing, functional gene identification, and CRISPR/Cas9 applications, addressing challenges in flavor, yield, and other important agrinomic traits, while ...

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.

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. Crosses were made between healthy plants within

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.

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.

Seedling salt tolerance in tomato [PDF]

, 2011
Soils with higher concentrations of salt are becoming more and more a constraint for many crops to obtain high yields. Wild tomato species, adapted to adverse environments, are a potential reservoir for genes underlying quantitative trait loci (QTL ...
