Transcript isoforms and alternative splicing in polyploid Brassica napus under heat and cold stress Open

Ryan Edward Bailey, Keith L. Adams · 2025

Background and Aims Polyploidization events have occurred many times during the evolution of flowering plants and have played a major role in genome evolution. Genes duplicated by polyploidy, termed homeologues, can diverge in function or …

Genome-Wide Analyses of Copy Number Variants in 751 Populus trichocarpa Individuals From Natural Populations Open

Yihan Wu, Keith L. Adams · 2025

Copy number variations (CNVs), including duplications and deletions of the genome ranging up to 1 Mb, are an important contributor to genomic variation, and may influence phenotypic variation. They are relatively understudied compared with…

Subgenome‐dominant expression and alternative splicing in response to Sclerotinia infection in polyploid Brassica napus and progenitors Open

Grant W. de Jong, Keith L. Adams · 2023

SUMMARY Polyploidy has played an extensive role in the evolution of flowering plants. Allopolyploids, with subgenomes containing duplicated gene pairs called homeologs, can show rapid transcriptome changes including novel alternative splic…

Taxonomically Restricted Genes Are Associated With Responses to Biotic and Abiotic Stresses in Sugarcane (Saccharum spp.) Open

Cláudio Benício Cardoso-Silva, Alexandre Hild Aono, Melina Cristina Mancini, Danilo Augusto Sforça, Carla Cristina da Silva , et al. · 2022

Orphan genes (OGs) are protein-coding genes that are restricted to particular clades or species and lack homology with genes from other organisms, making their biological functions difficult to predict. OGs can rapidly originate and become…

Orphan genes (OGs) are protein-coding genes that are restricted to particular clades or species and lack homology with genes from other organisms, making their biological function difficult to predict. OGs can rapidly originate and become …

A screen for mutants deficient in coronatine-mediated suppression of root immunity identifies Arabidopsis SDA1 as a novel integrator of immunity and phytohormone signaling Open

Yi Song, Xuecheng Zhang, Yichun Qiu, Annika L. Briggs, Yves Millet , et al. · 2021

Despite the importance of the root immune system in the interaction with rhizosphere microbes, the majority of genetic screens for immunity regulators have been performed in leaves. A previous screen identified 27 hsm ( h ormone-mediated s…

Changes in Alternative Splicing in Response to Domestication and Polyploidization in Wheat Open

Kuohai Yu, Man Feng, Guanghui Yang, Lv Sun, Zhen Qin , et al. · 2020

Alternative splicing (AS) occurs extensively in eukaryotes as an important mechanism for regulating transcriptome complexity and proteome diversity, but variation in the AS landscape in response to domestication and polyploidization in cro…

Global insights into duplicated gene expression and alternative splicing in polyploid Brassica napus under heat, cold, and drought stress Open

Joon S. Lee, Keith L. Adams · 2020

Polyploidy has been a prevalent process during plant evolution and it has made a major impact on the structure and evolution of plant genomes. Many important crop plants are polyploid. There is considerable interest in expression patterns …

Current status of the multinational Arabidopsis community Open

Keith L. Adams, Wagner Araújo, Sébastien Aubourg, Sacha Baginsky, Erica Bakker , et al. · 2020

The multinational Arabidopsis research community is highly collaborative and over the past thirty years these activities have been documented by the Multinational Arabidopsis Steering Committee (MASC). Here, we (a) highlight recent researc…

MEKK2 inhibits activation of MAP kinases in Arabidopsis Open

Yukino Nitta, Yichun Qiu, Hoda Yaghmaiean, Qian Zhang, Jianhua Huang , et al. · 2020

SUMMARY The Arabidopsis MEKK1‐MKK1/MKK2‐MPK4 kinase cascade is monitored by the nucleotide‐binding leucine‐rich‐repeat immune receptor SUMM2. Disruption of this kinase cascade leads to activation of SUMM2‐mediated immune responses. MEKK2, …

Divergence of duplicated genes by repeated partitioning of splice forms and subcellular localization Open

Yichun Qiu, Yii Van Tay, Yuan Ruan, Keith L. Adams · 2019

Summary Gene duplication is a prominent and recurrent process in plant genomes. Among the possible fates of duplicated genes, subfunctionalization refers to duplicates taking on different parts of the function or expression pattern of the …

Concerted Divergence after Gene Duplication in Polycomb Repressive Complexes Open

Yichun Qiu, Shao‐Lun Liu, Keith L. Adams · 2017

Duplicated genes are a major contributor to genome evolution and phenotypic novelty. There are multiple possible evolutionary fates of duplicated genes. Here, we provide an example of concerted divergence of simultaneously duplicated genes…

Evolution of cis-regulatory elements and regulatory networks in duplicated genes of Arabidopsis thaliana Open

Andrej A. Arsovski, Julian Pradinuk, Xu Guo, Sishuo Wang, Keith L. Adams · 2015

Plant genomes contain large numbers of duplicated genes that contribute to the evolution of new functions. Following duplication, genes can exhibit divergence in their coding sequence and their expression patterns. Changes in the cis-regul…

Duplicate Gene Divergence by Changes in MicroRNA Binding Sites in Arabidopsis and Brassica Open

Sishuo Wang, Keith L. Adams · 2015

Gene duplication provides large numbers of new genes that can lead to the evolution of new functions. Duplicated genes can diverge by changes in sequences, expression patterns, and functions. MicroRNAs play an important role in the regulat…
