Speciation with gene flow

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

A composite model of maize heterosis based on structural complementation and functional variants

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Heterosis is critical to high maize (Zea mays L.) yields; however, its genetic mechanism remains poorly understood because different molecular markers reflect distinct genetic components. This study uses a North Carolina II mating design to evaluate grain yield per plant of 87 hybrids derived from 29 recombinant inbred lines and three testers ...

Genetic analyses of leaf traits in an interspecific Zoysia japonica × Zoysia matrella F2 population

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Zoysiagrass (Zoysia spp.) is an important warm‐season turfgrass cultivated across tropical, subtropical, and temperate regions of the world. The genus is characterized by the presence of salt‐secreting glands on the adaxial leaf surface, which contribute to its high salt tolerance.

Development of an open‐pollinated genetic mapping framework to facilitate the identification of QTL in apples

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Genetic mapping of traits in apples (Malus domestica), a temperate woody perennial, is challenging due to high heterozygosity, long juvenility, and extensive spatial maintenance requirements for the populations. These factors limit the effective use of traditional quantitative trait locus (QTL) mapping methods in identifying the genetic basis ...

Considerations in the search for epistasis

Genome Biology
Epistasis refers to changes in the effect on phenotype of a unit of genetic information, such as a single nucleotide polymorphism or a gene, dependent on the context of other genetic units.

Dissecting genetic architecture and improving machine learning‑based genomic prediction of flowering time in Osmanthus fragrans by integrating structural variants

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Sweet osmanthus (Osmanthus fragrans), a traditional ornamental plant in China, exhibits substantial variation in autumn flowering time, which significantly affects landscape application and cultivation efficiency. Here, we performed a genome‐wide association study on 127 resequenced accessions classified into early, intermediate, and late ...

CKLF‐like MARVEL transmembrane domain‐containing superfamily 8 (CMTM8) promotes Notch signalling to maintain CD8+ T cell‐ and NK cell‐dependent tumour immune escape

British Journal of Pharmacology, Volume 183, Issue 17, Page 5211-5229, September 2026.
Background and Purpose The CKLF‐like MARVEL transmembrane domain containing superfamily (CMTM) has an important role in tumour immunity. The role of CMTM8 in tumour immune microenvironment (TIME) remains unknown. The aim was to investigate the relationship between CMTM8 and antitumour immunity. Experimental Approach Lentiviral system was established to

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 625-638, September 2026.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

DrdR Negatively Modulates the Expression of Flagellar Genes via Interaction With FleQ in Xanthomonas campestris

Molecular Plant Pathology, Volume 27, Issue 9, September 2026.
Upon activation by an unknown signal, DrdR targets FleQ, inhibiting its ATPase activity and DNA binding ability. This blocks FleQ from activating the transcription of flagellar genes, downregulating gene expression and suppressing swimming motility. ABSTRACT Response regulators (RRs) of two‐component signalling systems (TCSs) containing tandem receiver

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 ...
