Abstract Most diploid organisms have polyploid ancestors. The evolutionary process of polyploidization is poorly understood but has frequently been conjectured to involve some form ‘genome shock’, such as genome reorganization and subgenome expression dominance. Here we study in Arabidopsis suecica , a post-glacial allopolyploid species formed via hybridization thaliana arenosa . We generated chromosome-level assembly A. complemented it with polymorphism transcriptome data from all species....
Abstract Background It is apparent that genomes harbor much structural variation largely undetected for technical reasons. Such can cause artifacts when short-read sequencing data are mapped to a reference genome. Spurious SNPs may result from mapping of reads unrecognized duplicated regions. Calling SNP using the raw 1001 Arabidopsis Genomes Project we identified 3.3 million (44%) heterozygous SNPs. Given thaliana ( A. ) highly selfing, and extensively individuals have been removed,...
Summary Ustilago maydis is the causal agent of maize smut disease. During colonization process, fungus secretes effector proteins that suppress immune responses and redirect host metabolism in favor pathogen. As effectors play a critical role during plant colonization, their identification functional characterization are essential to understanding biotrophy Using biochemical, molecular, transcriptomic techniques, we performed U. Jasmonate/Ethylene signaling inducer 1 (Jsi1). Jsi1 interacts...
Embryonic polarity of invertebrates, amphibians and fish is specified largely by maternal determinants, which fixes cell fates early in development. In contrast, amniote embryos remain plastic can form multiple individuals until gastrulation. How their determined? the chick embryo, earliest known factor cVg1 (homologous to mammalian growth differentiation 1, GDF1), a transforming beta (TGFβ) signal expressed posteriorly before A molecular screen find upstream regulators normal manipulated...
Ribosomal RNA (rRNA) accounts for the majority of in eukaryotic cells, and is encoded by hundreds to thousands nearly identical gene copies, only a subset which are active at any given time. In Arabidopsis thaliana, 45S rRNA genes found two large ribosomal DNA (rDNA) clusters little known about contribution each overall transcription pattern species.
Over the past decades DNA sequencing technologies have been improving in aspects like quality, read length, runtimes and yields, all at a lower cost. Despite these improvements, genome assembly remains challenge projects, especially when different platforms are used. At present, there is no program that can handle assemble better than specialized software for each of them. Also, very few protocols available merging results from algorithms, or both. We present GARM, (Genome Assembler,...
The view on the role of light during seed germination stems mainly from studies with Arabidopsis (Arabidopsis thaliana), where is required to initiate this process. In contrast, white a strong inhibitor in other plants, exemplified by accessions Aethionema arabicum, another member Brassicaceae. Their seeds respond gene expression changes key regulators converse that Arabidopsis, resulting opposite hormone regulation and prevention germination. However, photoreceptors involved process A....
ABSTRACT Salmonella enterica subsp. serovar Typhimurium strain YU39 was isolated in 2005 the state of Yucatán, Mexico, from a human systemic infection. The is representative multidrug-resistant emergent sequence type 213 (ST213) genotype. complete genome composed chromosome and seven plasmids.
Abstract The majority of diploid organisms have polyploid ancestors. evolutionary process polyploidization (and subsequent re-diploidization) is poorly understood, but has frequently been conjectured to involve some form “genome shock” — partly inspired by studies in crops, where polyploidy linked major genomic changes such as genome reorganization and subgenome expression dominance. It unclear, however, whether dramatic would be characteristic natural polyploidization, or they are a product...
Abstract Background It is apparent that genomes harbor massive amounts of structural variation, and this variation has largely gone undetected for technical reasons. In addition to being inherently interesting, can cause artifacts when short-read sequencing data are mapped a reference genome. particular, spurious SNPs (that do not show Mendelian segregation) may result from mapping reads duplicated regions. Calling SNP using the raw 1001 Arabidopsis Genomes Project we identified 3.3 million...
Abstract Ustilago maydis (U. maydis) is the causal agent of maize smut disease. During colonization process, fungus secretes effector proteins which suppress immune responses and redirect host-metabolism in favor pathogen. Here we describe a novel strategy by U. induces plant jasmonate/ethylene (JA/ET) hormone signaling thereby biotrophic susceptibility. The Jasmonate/Ethylene inducer 1 ( Jsi1 ) possesses an ethylene-responsive element binding factor-associated amphiphilic repression (EAR)...

Their seeds respond gene expression changes key regulators converse resulting antipodal hormone regulation and prevention germination. photoreceptors involved process A. were unknown.
