Extraordinarily high leaf selenium to sulfur ratios define ‘se-accumulator’ plants [PDF]

open access: yes, 2007
Background and Aims: Selenium (Se) and sulfur (S) exhibit similar chemical properties. In flowering plants (angiosperms) selenate and sulfate are acquired and assimilated by common transport and metabolic pathways. It is hypothesized that most angiosperm

Genetic basis for broad interspecific compatibility in Solanum verrucosum

open access: yesThe Plant Journal, Volume 123, Issue 4, August 2025.
SUMMARY Solanum verrucosum Schlechtendal (2x = 2n = 24) is unique among the clade 4 Solanum Sect Petota species. In addition to being one of the only fully self‐compatible diploid potato species, S. verrucosum is the only clade 4 species that lacks prezygotic interspecific reproductive barriers. This allows S.

A SlMYB78‐regulated bifunctional gene cluster for phenolamide and salicylic acid biosynthesis during tomato domestication, reducing disease resistance

open access: yesJournal of Integrative Plant Biology, Volume 67, Issue 7, Page 1947-1964, July 2025.
The tomato transcription factor SlMYB78 controls a key metabolic gene cluster including ENHANCED PSEUDOMONAS SUSCEPTIBILTY 1, encoding a key enzyme that produces disease‐fighting compounds (phenolamides) and immune signals (salicylic acid). During domestication, tomatoes lost a superior variant (SlEPS1HapB), weakening disease resistance; restoring this

QTL analysis of pest resistance in the wild tomato Lycopersicon pennellii: QTLs controlling acylsugar level and composition

open access: yesTheoretical and Applied Genetics, 1996
Some accessions of Lycopersicon pennellii, a wild relative of the tomato Lycopersicon esculentum, are resistant to a number of important pests of cultivated tomato due to the accumulation of acylsugars, which constitute 90% of the exudate of type-IV trichomes in L. pennellii LA716. An interspecific F2 population, created by the cross L. esculentum x L.

Nonpreference of whitefly for oviposition in tomato genotypes

open access: yesScientia Agricola, 2002
The silverleaf whitefly is one of most important pests of tomato (Lycopersicon spp.). The use of host plant resistance to control this insect is an interesting, potentially useful technique, but in demand of more research.

A basic Helix-Loop-Helix (SlARANCIO), identified from a Solanum pennellii introgression line, affects carotenoid accumulation in tomato fruits [PDF]

open access: yes, 2019
Carotenoid accumulation in tomato (Solanum lycopersicum) fruits is influenced by environmental stimuli and hormonal signals. However, information on the relative regulatory mechanisms are scanty since many molecular players of the carotenoid biosynthetic

Role of LEAFLESS, an AP2/ERF family transcription factor, in the regulation of trichome specialized metabolism

open access: yesNew Phytologist, Volume 247, Issue 2, Page 774-790, July 2025.
Summary Acylsugars, specialized metabolites produced by trichomes of many solanaceous species, provide protection against biotic and abiotic stresses. Many acylsugar metabolic enzymes have been identified; however, regulatory factors remain unknown.

Acylsugars in tomato leaflets confer resistance to the South American tomato pinworm, Tuta absoluta Meyr

open access: yesScientia Agricola, 2006
Acylsugars present in the accession 'LA716' of Lycopersicon pennellii play an important role in the resistance to Tuta absoluta. This paper investigates the possible association between the resistance to T.
