Characterization of Polyploid Embryoid Lines Induced via Unfertilized Ovule Culture of Loquat (Eriobotrya japonica Lindl.)

Horticulturae
Polyploidy plays a significant role in loquat breeding, particularly in triploid breeding for seedless fruit production. Currently, loquat polyploid breeding primarily relies on natural seedling selection and sexual hybridization approaches.

Pitfalls and missing links in current understanding of 4D genomes

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression, maintaining genome stability, and guiding development. The convergence of chromosome conformation capture technologies, super‐resolution microscopy, and single‐cell epigenomics has transformed our understanding of ...

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.

Identification of resistance sources and genomic regions regulating spot blotch resistance in Asian bread wheat (Triticum aestivum L.) via genome‐wide association study

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Spot blotch (SB), caused by Bipolaris sorokiniana, is a major yield‐limiting disease of wheat (Triticum aestivum L.) in the warm, humid agroclimatic zones of South Asia. The development of resistant cultivars through molecular approaches offers a sustainable strategy for managing this disease.

Polyploid induction of Eucalyptus dunnii Maiden to generate waviability in breeding programs. [Polyploid induction of Eucalyptus dunnii Maiden to generate variability in breeding programs].

, 2022
Eucalyptus dunnii Maiden produces good quality cellulose pulp, showing good frost tolerance. However, in Uru-guay, it needs more than six years to reach the reproductive stage. Genome duplication was proposed as a strategy to obtain useful variability. The application of mitosis inhibitors for chromosomal duplication, in explants growing in vitro, was ...

Advances in gene cloning and functional genomics approaches for wheat (Triticum aestivum L.) improvement

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.) is a globally important cereal crop which provides ∼20% calories in human diet. Identifying genes and elucidating their functions is still challenging in wheat due to its large genome (∼16 Gb) with significant amount of repetitive elements.

Polyploidization using colchicine in horticultural plants: A review

, 2019
Polyploidization of plants occurs in nature but it is a slow and gradual process that has driven evolution and speciation throughout the ages. As time is important, polyploidization can be induced in a shorter period by using colchicine that interferes ...

Spatial transcriptomics provide insights into the secondary lateral rooting difficulties of tetraploid forsythia cuttings

Industrial Crops and Products
Polyploidy breeding is an important technique for crop improvement through artificial induction of chromosome doubling. In tetraploid forsythia, we observed a significant reduction in secondary lateral roots of cuttings, leading to low survival rates ...

Tandemly duplicated TaERF109 genes confer drought tolerance and post‐drought recovery in wheat

Journal of Integrative Plant Biology, Volume 68, Issue 6, Page 1744-1761, June 2026.
Tandemly duplicated TaERF109 transcription factor genes in wheat modulate growth traits and enhance drought tolerance by regulating the TaMADS56 transcription factor gene, cytokinin biosynthesis‐related genes, and nicotianamine synthase genes, revealing the critical role of tandemly duplicated genes in the coordination of stress responses and ...
