The sls‐1 and sls‐2 Genes Confer Significant Resistance to Septoria Leaf Spot (Septoria lycopersici L.) in Organic Field‐Grown Tomatoes (Solanum lycopersicum)

Plant Breeding, Volume 144, Issue 5, Page 705-714, October 2025.
ABSTRACT Septoria leaf spot (SLS) is a major foliar disease affecting tomato production, causing significant yield losses. This study evaluates the effect of two novel SLS resistance genes, sls‐1 and sls‐2, on SLS severity in open‐field tomatoes and their potential to be used in hybrid tomato varieties.

Soybean resistance to southern root‐knot nematode reduces nematode population density under field conditions

Crop Science, Volume 65, Issue 5, September/October 2025.
Abstract The southern root‐knot nematode [SRKN; Meloidogyne incognita (Kofoid & White) Chitwood] is one of the most damaging soybean (Glycine max [L.] Merr.) pathogens in the southern United States. Genetic resistance is the primary management strategy.

Phylogenomic and super‐pangenome analyses unveil the genetic landscape of tomato evolution and domestication

Plant Biotechnology Journal, Volume 23, Issue 9, Page 3783-3797, September 2025.
Summary The tomato (Solanum lycopersicum L.), a principal fruit crop, exhibits significant genetic diversity shaped by domestication and breeding. Analysis of the gene‐based super‐pangenome, a catalogue of all genes across diverse genome‐sequenced tomatoes, has not yet been fully explored.

Evidence of cryptic introgression in tomato (Solanum lycopersicum L.) based on wild tomato species alleles

BMC Plant Biology, 2012
Background Many highly beneficial traits (e.g. disease or abiotic stress resistance) have been transferred into crops through crosses with their wild relatives.

Wild tomato genome assemblies reveal structural variants and repeat content act as recombination barriers

Nature Communications
Crop wild relatives are used to improve cultivated plants and precise tracking of genetic introgression requires high-quality genome assemblies. Here we present de novo genome assemblies of two wild tomato species — the broadly stress-resistant Solanum ...

Resistance to Septoria lycopersici in Solanum (section Lycopersicon) species and in progenies of S. lycopersicum × S. peruvianum

, 2010
Septoria leaf spot (Septoria lycopersici) is one of the major fungal diseases of tomatoes (Solanum lycopersicum) in tropical and subtropical regions with humid climates and/or in areas cultivated under sprinkler irrigation systems. Sources of resistance have been found in accessions of Solanum (section Lycopersicon) species.
