Are We Witnessing a Speciation Continuum? Evidence From Current and Past Gene Flow in the Genus Oritrophium s.s. (Asteraceae) From the Tropical High Andes. [PDF]

Mol Ecol
ABSTRACT Determining species boundaries is key for appropriately assessing biodiversity. However, the continuity of the speciation process makes delimiting species a difficult task, especially for recently diverged taxa. Furthermore, past introgression may leave traces that result in reticulate evolutionary patterns, challenging the estimation of ...

Protoplast-Based Functional Genomics and Genome Editing: Progress, Challenges and Applications. [PDF]

Plant Cell Environ
ABSTRACT Protoplast‐based systems provide a powerful and versatile platform for exploring how plants sense and respond to their environment. By enabling the direct delivery of proteins, DNA, and RNA into plant cells after cell wall removal, this approach facilitates precise molecular dissection of signaling, stress adaptation, and gene regulation ...

The structure and allelic diversity of the self-incompatibility locus (S-locus) in diploid potatoes inferred from genome sequences and transcriptome data from styles and pollen. [PDF]

Plant Genome
Abstract Gametophytic self‐incompatibility (GSI) is a reproductive strategy to prevent inbreeding and promote outcrossing. Studies to understand molecular and evolutionary aspects of the self‐compatibility (SC)/self‐incompatibility (SI) system in the Solanaceae have been conducted using several genera including Petunia Juss., Nicotiana L., and Solanum ...

Genome-wide association study identifies quantitative trait loci associated with resistance to Verticillium dahliae race 3 in tomato. [PDF]

Plant Genome
Abstract Verticillium wilt (VW) disease, caused by Verticillium dahliae Kleb., is a major threat to tomato (Solanum lycopersicum L.) production. Identifying loci associated with VW resistance can accelerate breeding efforts and support sustainable disease management. Although the Ve1 and Ve2 genes confer resistance to V.

The role of tomato wild relatives in breeding disease-free varieties

Genetic Resources, 2022
Cultivated tomato (Solanum lycopersicum) is one of the most economically important and widely grown vegetable crops worldwide. However, tomato plants are often affected by biotic and abiotic stresses that reduce yield and affect fruit quality ...

Evaluation of a SUMO E2 conjugating enzyme involved in resistance to Clavibacter michiganensis subsp. michiganensis in Solanum peruvianum, through a tomato mottle virus VIGS assay

Frontiers in Plant Science, 2015
Clavibacter michiganensis subsp. michiganensis (Cmm) causes bacterial wilt and canker of tomato. Currently, no Solanum lycopersicum resistant varieties are commercially available, but some degree of Cmm resistance has been identified in Solanum ...

In Vitro Function of S RNases in Lycopersicon peruvianum

Molecules and Cells, 2001
S RNases are products of the S locus that are expressed in the stylar tissue of Lycopersicon peruvianum with the gametophytic self-incompatibility (SI) system. Two S RNases (S12 and Sa) with RNase activity from the S12Sa genotype of L. peruvianum were purified using gel filtration and cation-exchange chromatography.

Development of a locus-specific, co-dominant SCAR marker for assisted-selection of the Sw-5 (Tospovirus resistance) gene cluster in a wide range of tomato accessions [PDF]

, 2010
The best levels of broad-spectrum Tospovirus resistance reported in tomatoes thus far are conferred by the Sw-5 locus. This locus contains at least five paralogues (denoted Sw-5a through Sw-5e), of which Sw-5b represents the actual resistance gene.

Balancing Selection at the Tomato RCR3 Guardee Gene Family Maintains Variation in Strength of Pathogen Defense [PDF]

, 2012
Coevolution between hosts and pathogens is thought to occur between interacting molecules of both species. This results in the maintenance of genetic diversity at pathogen antigens (or so-called effectors) and host resistance genes such as the major ...

Loss of a histidine residue at the active site of S-locus ribonuclease is associated with self-compatibility in Lycopersicon peruvianum. [PDF]

Proceedings of the National Academy of Sciences, 1994
Gametophytic self-incompatibility in the Solanaceae is controlled by a single, multiallelic locus, the S locus. We have recently described an allele of the S locus of Lycopersicon peruvianum that caused this normally self-incompatible plant to become self-compatible.
