Mapping of Crown Rust (Puccinia coronata f. sp. avenae) Resistance Gene Pc54 and a Novel Quantitative Trait Locus Effective Against Powdery Mildew (Blumeria graminis f. sp. avenae) in the Oat (Avena sativa) Line Pc54

Belayneh Admassu-Yimer et al.

Summary: In this study, the genomic locations of the crown rust resistance gene Pc54 and the powdery mildew resistant gene QPm.18 in oats were identified using recombinant inbred line populations. Significantly linked molecular markers were also identified, providing potential for marker-assisted selection in oat breeding programs. These findings contribute to a better understanding of the molecular mechanisms of resistance to crown rust and powdery mildew in oats and offer valuable tools for oat breeding.

Speed breeding and early panicle harvest accelerates oat (Avena sativa L.) breeding cycles

Pablo Gonzalez-Barrios et al.

Summary: The study showed that using a speed breeding system can significantly reduce the time required for inbreeding in plants, particularly in oats where early seed harvesting with acceptable germination levels is achievable, which is crucial for breeding systems utilizing single-seed descent.

A five-transgene cassette confers broad-spectrum resistance to a fungal rust pathogen in wheat

Ming Luo et al.

Summary: Through the introduction of a transgene cassette containing five resistance genes into bread wheat, researchers have successfully generated wheat lines with highly resistant to aggressive and highly virulent Pgt isolates from around the world. This approach simplifies breeding efforts and enhances resistance levels, although strategic deployment of gene stacks may be needed to maintain effectiveness against new Pgt isolates.

BED domain-containing NLR from wild barley confers resistance to leaf rust

Chunhong Chen et al.

Summary: Leaf rust, caused by Puccinia hordei, is a severe fungal disease globally impacting barley production. Cloning of the Rph15 resistance gene from a wild barley progenitor and development of a KASP marker provide a new avenue for sustained leaf rust control. The resistance mediated by Rph15 and previously thought to be allelic with Rph16 is actually the same, allowing for efficient gene deployment in combating leaf rust.

Discovery and Chromosomal Location a Highly Effective Oat Crown Rust Resistance Gene Pc50-5

Joanna Toporowska et al.

Summary: The study identified a highly effective monogenic crown rust resistance gene, Pc50-5, and confirmed its potential in oat breeding through an allelism test. Molecular markers tightly linked to the Pc50-5 gene were developed and converted into SCAR markers through PCR, providing a valuable tool for oat breeding programs.

A universal karyotypic system for hexaploid and diploid Avena species brings oat cytogenetics into the genomics era

Wenxi Jiang et al.

Summary: A universal karyotyping nomenclature system based on oligo-FISH has been established for precise chromosome identification and comparative evolutionary studies in Avena species. This new system provides a powerful tool for describing genetic diversity, chromosomal rearrangements, and evolutionary relationships among Avena species through comparative cytogenetic and genomic approaches.

Incursions of divergent genotypes, evolution of virulence and host jumps shape a continental clonal population of the stripe rust pathogen Puccinia striiformis

Yi Ding et al.

Summary: This study examined the genetic features of the plant pathogen Puccinia striiformis f. sp. tritici (Pst) using historical isolates, identifying new genetic insights into the evolution of diverse rust pathogen phenotypes. Through genotypic, phenotypic, and genomic analyses, different genetic groups of Pst isolates were classified, showing distinct whole-genome variant levels between groups and exploring variable gene content following introduction. The research provides valuable information on how rust pathogens evolve following incursion into a geographically isolated region.

Genomic prediction and training set optimization in a structured Mediterranean oat population

Simon Rio et al.

Summary: The genetic structure observed in Mediterranean oats influences the effectiveness of genomic prediction and training set optimization. Higher predictive abilities were seen in intra-subspecies predictions compared to inter-subspecies predictions. Linear mixed model optimization criteria performed better than heuristic approaches in training set optimization, even in highly structured populations.
