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]
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]
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]
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 ...

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

In Vitro Function of S RNases in Lycopersicon peruvianum
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.

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

PERICLINAL CHIMERAS COMPOSED OF LYCOPERSICON PERUVIANUM AND L. ESCULENTUM DEMONSTRATE THAT S-LOCUS ASSOCIATED PROTEINS AND SELF-INCOMPATIBILITY CAN BE UNCOUPLED [PDF]
Lycopersicon peruvianum is a wild species of tomato that exhibits gametophytic self-incompatibility (S), wherein the SI response is controlled by the genotype of the pollen. Cultivated tomato (L. esculentum) is a self-compatible species.

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