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.

When bigger is better: the role of polyploidy in organogenesis [PDF]

, 2015
Defining how organ size is regulated, a process controlled not only by the number of cells but also by the size of the cells, is a frontier in developmental biology.

HSP101‐encoding NEO‐TETRAPLOID RICE FERTILITY GENE 1 regulates tapetum development through interaction with SAPK2 in polyploid rice

Journal of Integrative Plant Biology, EarlyView.
In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.

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.

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, EarlyView.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

HIPK2 and extrachromosomal histone H2B are separately recruited by Aurora-B for cytokinesis [PDF]

, 2018
Cytokinesis, the final phase of cell division, is necessary to form two distinct daughter cells with correct distribution of genomic and cytoplasmic materials.

PlantCTCIP: Chromatin Interaction Prediction Using Convolutional Neural Network and Transformer in Plants

Plant Biotechnology Journal, EarlyView.
ABSTRACT Chromatin interactions establish spatial proximity between distant regulatory elements and their target genes, significantly influencing gene expression, and phenotypic traits. In this study, we present a plant chromatin interaction prediction model called PlantCTCIP based on Convolutional Neural Networks and Transformer.

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

Polyploid Speciation

, 2016
Genome duplication represents a dramatic, yet relatively common, genomic change, having occurred in the evolutionary history of angiosperms, vertebrates, and yeast, among many other groups. The result of such duplications ('polyploidy,' the existence of multiple sets of chromosomes within the genome) has long been recognized and was implicated as a ...

Polyploidization in Liver Tissue

The American Journal of Pathology, 2014
Polyploidy (alias whole genome amplification) refers to organisms containing more than two basic sets of chromosomes. Polyploidy was first observed in plants more than a century ago, and it is known that such processes occur in many eukaryotes under a variety of circumstances.
