Perspectives on the application of genome editing technologies in crop breeding.

Most conventional and modern crop improvement methods exploit natural or artificially induced genetic variations and require laborious characterization of multiple generations of time-consuming genetic crosses. Genome editing systems, in contrast, provide the means to rapidly modify genomes in a precise and predictable way, making it possible to introduce improvements directly into elite varieties. Here, we describe the range of applications available to agricultural researchers using existing genome editin...

3D genome organization: a role for phase separation and loop extrusion?

In eukaryotes, genomic information is encoded in chromosomes, which occupy distinct territories within the nucleus. Inside these territories, chromosomes are folded in a hierarchical set of topological structures, called compartments, topologically associated domains and loops. Phase separation and loop extrusion are the mechanisms indicated to mediate the 3D organization of the genome, and gene activity and epigenetic marks determine the activity level of the formed chromatin domains. The main difference b...


Ecology and Evolution of Plant Microbiomes.

Microorganisms colonizing plant surfaces and internal tissues provide a number of life-support functions for their host. Despite increasing recognition of the vast functional capabilities of the plant microbiome, our understanding of the ecology and evolution of the taxonomically hyperdiverse microbial communities is limited. Here, we review current knowledge of plant genotypic and phenotypic traits as well as allogenic and autogenic factors that shape microbiome composition and functions. We give specific ...

Genome Sequence of sp. Strain SMS9 Identified in a Non-Axenic Culture of the Diatom .

Initial efforts to sequence the genome of the marine diatom were hampered by the presence of genetic material from bacteria, and there was sufficient material from some of these bacteria to enable the assembly of full chromosomes. Here, we report the genome of strain SMS9, one such bacterial species identified in a non-axenic culture of strain ST54. Its 5,482,391 bp circular chromosome contains 4,641 CDSs, and has a G+C content of 35.6%. Based on 16S rRNA comparison, phylotaxonomic analysis, and the genom...

The Pacific Biosciences assembled genome dataset from a parthenogenetic New Zealand wild population of the longhorned tick, Neumann, 1901.

The longhorned tick, , feeds upon a wide range of bird and mammalian hosts. Mammalian hosts include cattle, deer, sheep, goats, humans, and horses. This tick is known to transmit a number of pathogens causing tick-borne diseases, and was the vector of a recent serious outbreak of oriental theileriosis in New Zealand. A New Zealand-USA consortium was established to sequence, assemble, and annotate the genome of this tick, using ticks obtained from New Zealand's North Island. In New Zealand, the tick is consi...

The alternative reality of plant mitochondrial DNA: One ring does not rule them all.

Plant mitochondrial genomes are usually assembled and displayed as circular maps based on the widely-held view across the broad community of life scientists that circular genome-sized molecules are the primary form of plant mitochondrial DNA, despite the understanding by plant mitochondrial researchers that this is an inaccurate and outdated concept. Many plant mitochondrial genomes have one or more pairs of large repeats that can act as sites for inter- or intramolecular recombination, leading to multiple ...

Construction and comparison of three reference-quality genome assemblies for soybean.

We report reference-quality genome assemblies and annotations for two accessions of soybean (Glycine max) and one of Glycine soja, the closest wild relative of G. max. The G. max assemblies are for widely used U.S. cultivars: the northern line 'Williams 82' (Wm82); and the southern line 'Lee'. The Wm82 assembly improves the prior published assembly, and the Lee and G. soja assemblies are new for these accessions. Comparisons among the three accessions show generally high structural conservation, but nucleot...

Genomic evidence of genetic variation with pleiotropic effects on caterpillar fitness and plant traits in a model legume.

Plant-insect interactions are ubiquitous, and have been studied intensely because of their relevance to damage and pollination in agricultural plants, and to the ecology and evolution of biodiversity. Variation within species can affect the outcome of these interactions. Specific genes and chemicals that mediate these interactions have been identified, but genome- or metabolome-scale studies might be necessary to better understand the ecological and evolutionary consequences of intraspecific variation for p...

Engineered Cas9 variant tools expand targeting scope of genome and base editing in rice.

Recently, some newly engineered SpCas9 variants, such as xCas9 3.7 and Cas9-NG, expand the PAM recognition site to NG and show function efficiency in mammalian cells. However, there is still not enough comparative data for their efficiencies on the genome and base editing in plants. In addition, there is also a lack of enhanced specific Cas9 variant with NG PAM. Here, we developed a serial of genome editing tools using different Cas9 variants containing the xCas9, the Cas9-NG and the enhanced specific Cas9-...

Effect of floristic composition and configuration on plant root mycobiota: a landscape transposition at a small scale.

Fungal communities in the root endosphere are heterogeneous at fine scale. The passenger hypothesis assumes that this heterogeneity is driven by host plant distribution. Plant composition and host plant configuration should then influence root fungal assemblages. We used a large-scale experimental design of 25 mixtures of grassland plants. We sampled Brachypodium pinnatum in each mesocosm, and used amplicon mass-sequencing to analyze the endospheric mycobiota. We used plant distribution maps to assess plant...

The Plant "Resistosome": Structural Insights into Immune Signaling.

Plant innate immunity is triggered via direct or indirect recognition of pathogen effectors by the NLR family immune receptors. Mechanistic understanding of plant NLR function has relied on structural information from individual NLR domains and inferences from studies on animal NLRs. Recent reports of the cryo-EM structures of the Arabidopsis plant immune receptor ZAR1 in monomeric inactive and transition states, as well as the active oligomeric state or the "resistosome," have afforded a quantum leap in ou...

Linked-read sequencing of gametes allows efficient genome-wide analysis of meiotic recombination.

Meiotic crossovers (COs) ensure proper chromosome segregation and redistribute the genetic variation that is transmitted to the next generation. Large populations and the demand for genome-wide, fine-scale resolution challenge existing methods for CO identification. Taking advantage of linked-read sequencing, we develop a highly efficient method for genome-wide identification of COs at kilobase resolution in pooled recombinants. We first test this method using a pool of Arabidopsis F recombinants, and recap...

Long-Read based Novel Sequence Insertion Detection with rCANID.

Novel sequence insertion (NSI) is an essential category of genome structural variations (SVs), which represents DNA segments absent from the reference genome assembly. It has important biological functions and strong correlation with phenotypes and diseases. The rapid development of long-read sequencing technologies provides the opportunities to discover NSIs more sensitively, since the much longer reads are helpful for the assembly and location of the novel sequences. However, most of state-of-the-art long...

This hybrid approach allowed to assemble the nuclear genome in 14 pseudo-molecules wi...

Selective Metal-Phenolic Assembly from Complex Multicomponent Mixtures.

Selective self-assembly in multicomponent mixtures offers a method for isolating desired components from complex systems for the rapid production of functional materials. Developing approaches capable of selective assembly of "target" components into intended three-dimensional structures is challenging because of the intrinsically high complexity of multicomponent systems. Herein, we report the selective coordination-driven self-assembly of metal-phenolic networks (MPNs) from a series of complex multicompon...
