Asymmetric Divergence in Transmitted SNPs of DNA Replication/Transcription and Their Impact on Gene Expression in Polyploid Brassica napus

Frontiers in Genetics, 2021
The marked increase in plant genomic data has provided valuable resources for investigating the dynamic evolution of duplicate genes in polyploidy. Brassica napus is an ideal model species for investigating polyploid genome evolution.

Mechanisms of Thrombocytosis in Iron‐Deficiency Anemia

European Journal of Haematology, EarlyView.
ABSTRACT Iron‐deficiency anemia is frequently accompanied by reactive thrombocytosis, yet the mechanisms underlying this association remain incompletely understood. Beyond impaired erythropoiesis, iron availability has emerged as an active regulator of hematopoietic lineage decisions.

Naturally Occurring Triploidy in Cannabis

Plants, 2023
Polyploidy is a significant evolutionary process in plants that involves the duplication of genomic content and has been recognized as a key mechanism driving plant diversification and adaptation.

The ecology of polyploid establishment and exclusion, with implications for polyploid biogeography

New Phytologist
Summary The relationship between polyploid formation, triploid fitness and plant reproduction has been studied for over a century, and uniparental reproduction has long been recognized to play a crucial role in polyploid establishment.

High‐quality genome of elite peanut cultivar ZH05 reveals subgenome asymmetry, pan‐genome diversity, and breeding insights

Journal of Integrative Plant Biology, EarlyView.
A high‐quality reference genome for the elite peanut cultivar Zhonghua No. 5 revealed differing evolutionary paths between the two peanut subgenomes. SubA has higher overall gene expression and more open chromatin, whereas SubB has stronger structural organization, higher DNA methylation, and greater adaptive diversity associated with peanut evolution ...

Illegitimate Recombination Between Homeologous Genes in Wheat Genome

Frontiers in Plant Science, 2020
Polyploidies produce a large number of duplicated regions and genes in genomes, which have a long-term impact and stimulate genetic innovation. The high similarity between homeologous chromosomes, forming different subgenomes, or homologous regions after

Recent advances in the genomics of sugarcane (Saccharum)

Journal of Integrative Plant Biology, EarlyView.
This review systematically summarizes advances in sugarcane genomics, evolution, classification, and breeding practices. It identifies key research bottlenecks and proposes an integrated research framework to facilitate predictive sugarcane breeding, which provides valuable references for genetic improvement of other complex polyploid crops.

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.
