Nascent transcription and the associated cis-regulatory landscape in rice

This study identifies transcribed intergenic regions in rice that function as regulatory elements, associated with gene expression and chromatin interactions.

Fitness costs and benefits of gene expression plasticity in rice under drought

This study examines selection on drought-induced gene expression plasticity in rice, finding that housekeeping genes are disfavored to switch off under drought, while selection acts polygenically on co-expressed gene modules.

Archaeogenomics of a ~2,100-year-old Egyptian leaf provides a new timestamp on date palm domestication

The paper analyzes an ancient date palm leaf to determine the timing of gene flow from wild relatives to domesticated date palms, finding hybridization occurred at least 2,100 years ago.

Selection on ancient variations drives the adaptive radiation of Metrosideros across the Hawaiian archipelago

This study investigates how ancient genetic variations drive adaptive radiation in Hawaiian Metrosideros, showing balancing selection on pre-existing haplotypes facilitates diversification despite limited genetic diversity.

Telomere lengths in plants are correlated with flowering time variation

The paper finds a negative correlation between telomere length and flowering time in Arabidopsis thaliana, rice, and maize, suggesting a link between telomere dynamics and plant life history strategies.

Nanopore-based genome assembly and the evolutionary genomics of basmati rice

The paper assembles high-quality genomes of two basmati rice varieties using nanopore sequencing and identifies structural variations, gene flow, and genetic groupings in circum-basmati rice.

Divergent selection and primary gene flow shape incipient speciation of a riparian tree on Hawaii Island

This study investigates the role of divergent selection and gene flow in the incipient speciation of a riparian tree in Hawaii, finding genomic islands of divergence linked to regulatory genes and positive selection.

Multiple origin but single domestication led to domesticated Asian rice

This study reanalyzes rice domestication data to show multiple origins but single domestication event with allele introgression.
