Open AccessUnraveling the genome of Bacillus velezensis MEP218, a strain producing fengycin homologs with broad antibacterial activity: comprehensive comparative genome analysis
Bacillus sp. MEP218, a soil bacterium with high potential as a source of bioactive molecules, produces mostly C16–C17 fengycin and other cyclic lipopeptides (CLP) when growing under previously optimized culture c...

Open AccessDiversity of gene expression responses to light quality in barley
Light quality influence on barley development is poorly understood. We exposed three barley genotypes with either sensitive or insensitive response to two light sources producing different light spectra, fluor...

Open AccessGET_PANGENES: calling pangenes from plant genome alignments confirms presence-absence variation
Crop pangenomes made from individual cultivar assemblies promise easy access to conserved genes, but genome content variability and inconsistent identifiers hamper their exploration. To address this, we define...

Pangenome Analysis of Plant Transcripts and Coding Sequences
The pangenome of a species is the sum of the genomes of its individuals. As coding sequences often represent only a small fraction of each genome, analyzing the pangene set can be a cost-effective strategy for...

Scripting Analyses of Genomes in Ensembl Plants
Ensembl Plants (http://plants.ensembl.org) offers genome-scale information for plants, with four releases per year. As of release 47 (April 2020) it features 79 species ...

Open AccessGradual polyploid genome evolution revealed by pan-genomic analysis of Brachypodium hybridum and its diploid progenitors
Our understanding of polyploid genome evolution is constrained because we cannot know the exact founders of a particular polyploid. To differentiate between founder effects and post polyploidization evolution,...

Open AccessFine-tuning of the flowering time control in winter barley: the importance of HvOS2 and HvVRN2 in non-inductive conditions
In winter barley plants, vernalization and photoperiod cues have to be integrated to promote flowering. Plant development and expression of different flowering promoter (HvVRN1, HvCO2, PPD-H1, HvFT1, HvFT3) and r...

Resequencing theVrs1 gene in Spanish barley landraces revealed reversion of six-rowed to two-rowed spike
Six-rowed spike 1 (Vrs1) is a gene of major importance for barley breeding and germplasm management as it is the main gene determining spike row-type (2-rowed vs. 6-rowed). This is a widely used DUS trait, and ha...

Article
Open AccessExtensive gene content variation in the Brachypodium distachyon pan-genome correlates with population structure
While prokaryotic pan-genomes have been shown to contain many more genes than any individual organism, the prevalence and functional significance of differentially present genes in eukaryotes remains poorly un...

FootprintDB: Analysis of Plant Cis-Regulatory Elements, Transcription Factors, and Binding Interfaces
FootprintDB is a database and search engine that compiles regulatory sequences from open access libraries of curated DNA cis-elements and motifs, and their associated transcription factors (TFs). It systematic...

RSAT::Plants: Motif Discovery in ChIP-Seq Peaks of Plant Genomes
In this protocol, we explain how to run ab initio motif discovery in order to gather putative transcription factor binding motifs (TFBMs) from sets of genomic regions returned by ChIP-seq experiments. The protoco...

RSAT::Plants: Motif Discovery Within Clusters of Upstream Sequences in Plant Genomes
The plant-dedicated mirror of the Regulatory Sequence Analysis Tools (RSAT, http://plants.rsat.eu) offers specialized options for researchers dealing with plant tr...

BARLEYMAP: physical and genetic map** of nucleotide sequences and annotation of surrounding loci in barley
The BARLEYMAP pipeline was designed to map both genomic sequences and transcripts against sequence-enriched genetic/physical frameworks, with plant breeders as the main target users. It reports the most proba...

Selection footprints in barley breeding lines detected by combining genoty**-by-sequencing with reference genome information
This study is a retrospective analysis of an elite cross from the Spanish National Barley Breeding Program. This was the most successful cross produced in the breeding program in the past 20 years. The progeny...

Loss of neuronal 3D chromatin organization causes transcriptional and behavioural deficits related to serotonergic dysfunction
The interior of the neuronal cell nucleus is a highly organized three-dimensional (3D) structure where regions of the genome that are linearly millions of bases apart establish sub-structures with specialized ...

Open AccessIntegrating bioinformatic resources to predict transcription factors interacting with cis-sequences conserved in co-regulated genes
Using motif detection programs it is fairly straightforward to identify conserved cis-sequences in promoters of co-regulated genes. In contrast, the identification of the transcription factors (TFs) interacting w...

Open AccessGenetic recombination is associated with intrinsic disorder in plant proteomes
Intrinsically disordered proteins, found in all living organisms, are essential for basic cellular functions and complement the function of ordered proteins. It has been shown that protein disorder is linked t...

OsRMC, a negative regulator of salt stress response in rice, is regulated by two AP2/ERF transcription factors
High salinity causes remarkable losses in rice productivity worldwide mainly because it inhibits growth and reduces grain yield. To cope with environmental changes, plants evolved several adaptive mechanisms, ...
