ksrates: positioning whole-genome duplications relative to speciation events in KS distributions
[article]
2021
bioRxiv
pre-print
AbstractSummaryWe present ksrates, a user-friendly command-line tool to position ancient whole-genome duplication (WGD) events with respect to speciation events in a phylogeny by comparing paralog and ...
ortholog KS distributions derived from genomic or transcriptomic sequences, while adjusting for substitution rate differences among the lineages involved.Availability and implementationksrates is implemented ...

Chromosome level genome assembly and annotation of highly invasive Japanese stiltgrass (Microstegium vimineum)
2021
Genome Biology and Evolution
We find corroborating evidence from Ks plots for a stiltgrass-specific duplication event, distinct from the more ancient grass-specific duplication event. ...
The majority of LTR-retrotransposons are derived from a significant expansion in the past 1-2 million years, suggesting the presence of relatively young LTR-retrotransposon lineages. ...

The genome of Hibiscus hamabo reveals its adaptation to saline and waterlogged habitat
2022
Horticulture Research
Our analyses suggested that H. hamabo has undergone two recent successive polyploidy events, a whole-genome duplication followed by a whole-genome triplication, resulting in an unusually large gene number ...
In roots, genes that regulate ion channels involved in biosynthetic and metabolic processes responded quickly to adjust the ion concentration and provide metabolic products to protect root cells, whereas ...
