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

Biochemical 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.

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

Theoretical 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]

Sexual 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.

CRISPR/Cas9‐Mediated Knockout of LbSP1 and LbSP5G1 Reveals Efficient Customization of Shoot Architecture in Black Goji Berry

Plant Biotechnology Journal, EarlyView.
ABSTRACT Goji is recognized as a nutritionally rich superfruit with medicinal and industrial importance. However, its inherently indeterminate growth habit causes asynchronous flowering and uneven fruit ripening, resulting in harvesting inefficiency with high labour costs and low fruit yield.

Combined Phosphorus and Potassium Starvation Upregulates Sodium Accumulation by HKT1;1 in Tomato Plants

Plant, Cell &Environment, Volume 49, Issue 11, Page 7888-7899, November 2026.
ABSTRACT Na+ can substitute K+ under K+ deficiency conditions, which is denominated as beneficial Na+. Despite its relevance at the physiological level and its interest in agriculture, the mechanisms allowing its uptake and use by plants remain unclear.

Growth Temperature Alters the Thermal Sensitivity of Mesophyll Conductance in Wild and Cultivated Tomato

Plant, Cell &Environment, Volume 49, Issue 11, Page 7946-7956, November 2026.
ABSTRACT Mesophyll conductance (gm) is a key component of internal CO2 diffusion and can limit photosynthesis in C3 leaves. Temperature responses of gm are commonly treated as intrinsic properties of the leaf, yet it remains unclear whether they acclimate to growth conditions. Here, we tested whether growth temperature alters the thermal sensitivity of

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, Volume 49, Issue 11, Page 8437-8453, November 2026.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

A Novel AP2/ERF Transcription Factor Controls Trichome Initiation and Fruit Development in Cucumber

Plant Biotechnology Journal, Volume 24, Issue 9, Page 5077-5093, September 2026.
ABSTRACT Trichomes, the hair‐like outgrowths of the plant epidermis, are critical for defence, reproduction and development. However, the underlying molecular mechanisms governing their initiation remain elusive. Here, we identified CsGL2, an AP2/ERF transcription factor, as a key integrator controlling trichome initiation and fruit development in ...

eQTL Meta‐Analysis Reveals Conserved and Population‐Specific Regulatory Variation Underlying Nutritional Trait Evolution and Domestication in Tomato

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A comprehensive meta‐analysis of expression quantitative trait loci (eQTLs) across five diverse tomato populations reveals a high‐resolution atlas of transcriptional regulation and uncovers conserved and population‐specific regulatory architectures underlying fruit nutritional quality traits, including flavonoids, sugars, organic acids, carotenoids ...

Advanced backcross QTL analysis of a Lycopersicon esculentum × L. pennellii cross and identification of possible orthologs in the Solanaceae [PDF]

Theoretical and Applied Genetics, 2004
In this study, the advanced backcross QTL (AB-QTL) mapping strategy was used to identify loci for yield, processing and fruit quality traits in a population derived from the interspecific cross Lycopersicon esculentum E6203 x Lycopersicon pennellii accession LA1657.
