Integrated multi-omics reveals contrasting epigenetic patterns in leaf and root morphogenesis in Aegilops speltoides

Crop Journal
Aegilops speltoides, the closest ancestor of the wheat B subgenome, has been well studied genomically. However, the epigenetic landscape of Ae. speltoides and the effects of epigenetics on its growth and development remain poorly understood.

A likelihood ratio test for detecting shifts in homeolog expression ratios in allopolyploids

New Phytologist, Volume 249, Issue 1, Page 603-617, January 2026.
Summary Allopolyploids arise through hybridization between related species, carrying multiple sets of chromosomes from distinct progenitors, referred to as subgenomes. Within allopolyploids, duplicated genes across subgenomes, called homeologs, are thought to enhance environmental robustness by shifting their expression ratios depending on ...

Polymerase chain reaction single strand conformational polymorphism analysis of intra- and interspecific variations in organellar DNA regions of Aegilops mutica and related species

, 1996
In order to study the phylogeny of Aegilops mutica in the genera of Triticum and Aegilops, variations in chloroplast and mitochondrial DNA regions were investigated by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP ...

A molecular cytogenetic perspective on chromosome biology and crop improvement

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract The age of molecular cytogenetic analysis of crop plants dawned in the late 1960s and early 1970s with new advances in the identification of somatic chromosomes by C‐banding and fluorescence in situ hybridization concurrent with advances in DNA cloning, sequencing, and mapping. In this perspective article dedicated to Ronald Phillips, I review

Current Status and Future Direction of the High‐Temperature Resistance in Wheat to Control Stripe Rust

Molecular Plant Pathology, Volume 26, Issue 12, December 2025.
High‐temperature resistance: A gentle might to cradle wheat against stripe rust—it draws heat's strength, spanning growth stages, outpacing pathogen shifts, a shield for fields in a warming world. ABSTRACT This review summarises the current advances and future perspectives on high‐temperature resistance in wheat against stripe rust, caused by the ...

Breeding of Bread Wheat With Drought Adaptive Root Traits

Food and Energy Security, Volume 14, Issue 6, November/December 2025.
ABSTRACT Global wheat production is extending to dryland and tropical environments prone to drought and heat stress due to breeding and deploying new‐generation ideotypes with desirable product profiles. However, yield gains are low and stagnant under these environments, attributable to abiotic stresses, primarily drought.

New insights into the origin of the B genome of hexaploid wheat: Evolutionary relationships at the SPA genomic region with the S genome of the diploid relative Aegilops speltoides

BMC Genomics, 2008
Background Several studies suggested that the diploid ancestor of the B genome of tetraploid and hexaploid wheat species belongs to the Sitopsis section, having Aegilops speltoides (SS, 2n = 14) as the closest identified relative.

Metabolite‐based resistance in wheat varieties to aphid virus vectors: progress and future opportunities

Pest Management Science, Volume 81, Issue 11, Page 7276-7287, November 2025.
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Insights From the ‘Black Box’: Survival Strategies of Wheat Rusts and Their Epidemiological Significance

Plant Pathology, Volume 74, Issue 6, Page 1504-1518, August 2025.
Literature demonstrates that wheat rusts can survive through sexual reproduction on alternate hosts, asexual reproduction on wild grasses or volunteers and migration to more favourable areas during critical periods. ABSTRACT Survival between cropping seasons is a challenge for crop pathogens and can dramatically impact epidemic recurrence and ...
