Of dups and dinos : evolution at the K/Pg boundary [PDF]

, 2016
Fifteen years into sequencing entire plant genomes, more than 30 paleopolyploidy events could be mapped on the tree of flowering plants (and many more when also transcriptome data sets are considered). While some genome duplications are very old and have

The Evolution of Locally Adaptive Chromosome Inversions in Mimulus guttatus

Molecular Ecology, EarlyView.
ABSTRACT Chromosomal inversion polymorphisms are ubiquitous across the diversity of diploid organisms and play a significant role in the evolution of adaptations in those species. Inversions are thought to operate as supergenes by trapping adaptive alleles at multiple linked loci through the suppression of recombination. While there is now considerable

Roots Structure and Development of Austrobaileya scandens (Austrobaileyaceae) and Implications for Their Evolution in Angiosperms [PDF]

, 2020
Since the resolution of the ANA grade [Amborellales, Nymphaeales, Austrobaileyales] as sister to all other flowering plants, a few comparative studies of root structure have suggested that some of their anatomical traits could be of importance to ...

Extranuclear function of Arabidopsis HOOKLESS1 regulates pleiotropic developmental processes in a non‐cell‐autonomous manner

New Phytologist, Volume 246, Issue 2, Page 616-630, April 2025.
Summary N‐acetyltransferase HOOKLESS1 (HLS1) in Arabidopsis, a recognized pivotal factor in hook formation, is also implicated in multifaceted developmental processes including plastochron and leaf senescence. However, its molecular function remains to be elucidated.

The complete chloroplast genome of Aquilegia barnebyi, a basal eudicot species [PDF]

Mitochondrial DNA Part B, 2020
Aquilegia barnebyi, belonging to the genus Aquilegia (Ranunculaceae), is a member of basal eudicot species. In this study, we obtained the complete chloroplast (cp) genome of A. barnebyi. The genome size is 161,954 bp with a GC content of 38.98%.

AtGCS promoter-driven clustered regularly interspaced short palindromic repeats/Cas9 highly efficiently generates homozygous/biallelic mutations in the transformed roots by Agrobacterium rhizogenes–mediated transformation

Frontiers in Plant Science, 2022
Agrobacterium rhizogenes–mediated (ARM) transformation is an efficient and powerful tool to generate transgenic roots to study root-related biology. For loss-of-function studies, transgenic-root-induced indel mutations by CRISPR/Cas9 only with homozygous/

Harnessing promoter elements to enhance gene editing in plants: perspectives and advances

Plant Biotechnology Journal, Volume 23, Issue 5, Page 1375-1395, May 2025.
Summary Genome‐edited plants, endowed with climate‐smart traits, have been promoted as tools for strengthening resilience against climate change. Successful plant gene editing (GE) requires precise regulation of the GE machinery, a process controlled by the promoters, which drives its transcription through interactions with transcription factors (TFs ...

Gunnerales are sister to other core eudicots: implications for the evolution of pentamery [PDF]

American Journal of Botany, 2003
Phylogenetic relationships among many lineages of angiosperms have been clarified via the analysis of large molecular data sets. However, with a data set of three genes (18S rDNA, rbcL, and atpB), relationships among lineages of core eudicots (Berberidopsidales, Caryophyllales, Gunnerales, Santalales, Saxifragales, asterids, rosids) remain essentially ...

The “fossilized” mitochondrial genome of Liriodendron tulipifera: ancestral gene content and order, ancestral editing sites, and extraordinarily low mutation rate [PDF]

, 2013
BACKGROUND: The mitochondrial genomes of flowering plants vary greatly in size, gene content, gene order, mutation rate and level of RNA editing. However, the narrow phylogenetic breadth of available genomic data has limited our ability to reconstruct ...
