Near-complete telomere-to-telomere de novo genome assembly in Egyptian clover (Trifolium alexandrinum).

Egyptian clover (Trifolium alexandrinum L.), also known as berseem clover, is an important forage crop to Semi-arid conditions that was domesticated in ancient Egypt since 6,000 years BC and introduced and well adapted to numerous countries including India, Pakistan, Turkey, and Mediterranean region. Despite its agricultural importance, genomic research on Egyptian clover has been limited to developing efficient modern breeding programs.

The haplotype-phased genome assembly facilitated the deciphering of the bud dormancy-related QTLs in Prunus mume.

Bud dormancy is a vital physiological process in woody perennials, facilitating their adaptation to seasonal environmental changes. Satisfying genotype-specific chilling requirements (CR) and heat requirements (HR) through exposure to specific chilling and warm temperatures is essential for dormancy release and the subsequent resumption of growth. The genetic mechanisms regulating bud dormancy traits in Prunus mume remain unclear.

De novo sequencing allows genome-wide identification of genes involved in galactomannan synthesis in locust bean (Ceratonia siliqua).

Locust bean (Ceratonia siliqua) accumulates the galactomannan (GM) locust bean gum (LBG) in its seeds. LBG is a major industrial raw material used as a food thickener and gelling agent, whose unique properties mean that it cannot be readily replaced by other GMs. Whereas much is known about GM accumulation and the genes associated with GM biosynthesis in legumes, the genes involved in GM biosynthesis in C.

Epigenetic control of tetrapyrrole biosynthesis by m4C DNA methylation in a cyanobacterium.

Epigenetic DNA modifications are pivotal in eukaryotic gene expression, but their regulatory significance in bacteria is less understood. In Synechocystis 6803, the DNA methyltransferase M.Ssp6803II modifies the first cytosine in the GGCC motif, forming N4-methylcytosine (GGm4CC).

A fully phased, chromosome-scale genome of sugar beet line FC309 enables the discovery of Fusarium yellows resistance QTL.

Sugar beet (Beta vulgaris L.) is a global source for table sugar and animal fodder. Here we report a highly contiguous, haplotype phased genome assembly and annotation for sugar beet line FC309.

The burst of satellite DNA in Leptidea wood white butterflies and their putative role in karyotype evolution.

Satellite DNAs (satDNAs) are abundant components of eukaryotic genomes, playing pivotal roles in chromosomal organization, genome stability, and evolution. Here, we combined cytogenetic and genomic methods to characterize the satDNAs in the genomes of Leptidea butterflies. Leptidea is characterized by the presence of a high heterochromatin content, large genomes, and extensive chromosomal reshuffling as well as the occurrence of cryptic species.

Chromosome-level genome assembly of the medicinal insect Blaps rhynchopetera using Nanopore and Hi-C technologies.

Blaps rhynchopetera Fairmaire is a significant medicinal resource in southwestern China. We utilized Nanopore and Hi-C technologies in combination to generate a high-quality, chromosome-level assembly of the B. rhynchopetera genome and described its genetic features.

Pan-lineage Mycobacterium tuberculosis reference genome for enhanced molecular diagnosis.

In Mycobacterium tuberculosis (MTB) control, whole genome sequencing-based molecular drug susceptibility testing (molDST-WGS) has emerged as a pivotal tool. However, the current reliance on a single-strain reference limits molDST-WGS's true potential. To address this, we introduce a new pan-lineage reference genome, 'MtbRf'.

Propagation path of a flowering cherry (Cerasus × yedoensis) cultivar 'Somei-Yoshino' traced by somatic mutations.

In the long history of human relations with flowering cherry trees in Japan, 'Somei-Yoshino' occupies an exceptional position among a variety of flowering trees: it is a self-incompatible interspecific hybrid but has been enthusiastically planted by grafting throughout Japan, due most likely to its flamboyant appearance upon full bloom. Thus, 'Somei-Yoshino' gives us a rare opportunity to trace and investigate the occurrence and distribution of somatic mutations within a single plant species through analysis of the genomes of the clonally propagated trees grown under a variety of geographical and artificial environments. In the studies presented here, a total of 46 samples of 'Somei-Yoshino' trees were collected and their genomes were analysed.

A high-quality genome assembly reveals adaptations underlying glossy, wax-coated leaves in the heat-tolerant wild raspberry Rubus leucanthus.

With glossy, wax-coated leaves, Rubus leucanthus is one of the few heat-tolerant wild raspberry trees. To ascertain the underlying mechanism of heat tolerance, we generated a high-quality genome assembly with a genome size of 230.9 Mb and 24,918 protein-coding genes.

Insights from the first chromosome-level genome assembly of the alpine gentian Gentiana straminea Maxim.

Gentiana straminea Maxim. is a perennial herb and mainly distributed in the Qinghai-Tibetan Plateau. To adapt to the extreme environment, it has developed particular morphological, physiological, and genetic structures.

A chromosome-level genome assembly provides insights into the local adaptation of Tamarix austromongolica in the Yellow River Basin, China.

Tamarix austromongolica is endemic to the Yellow River Basin and has adapted to diverse ecological settings in the region, including the arid areas of northwestern China and the saline soil regions of the Yellow River Delta. However, the genetic basis of its local adaptation remains unclear. We report a chromosome-level assembly of the T.

A haplotype-resolved reference genome of a long-distance migratory bat, Pipistrellus nathusii (Keyserling & Blasius, 1839).

We present a complete, chromosome-scale reference genome for the long-distance migratory bat Pipistrellus nathusii. The genome encompasses both haplotypic sets of autosomes and the separation of both sex chromosomes by utilizing highly accurate long-reads and preserving long-range phasing information through the use of three-dimensional chromatin conformation capture sequencing (Hi-C). This genome, accompanied by a comprehensive protein-coding sequence annotation, provides a valuable genomic resource for future investigations into the genomic bases of long-distance migratory flight in bats as well as uncovering the genetic architecture, population structure and evolutionary history of Pipistrellus nathusii.

Genomic variation across distribution of Micro-Tom, a model cultivar of tomato (Solanum lycopersicum).

Micro-Tom is a cultivar of tomato (Solanum lycopersicum), which is known as a major crop and model plant in Solanaceae. Micro-Tom has phenotypic traits such as dwarfism, and substantial EMS-mutagenized lines have been reported. After Micro-Tom was generated in Florida, USA, it was distributed to research institutes worldwide and used as a genetic resource.

Uncovering DNA methylation landscapes to decipher evolutionary footprints of phenotypic diversity in chickpea.

Genetic diversity and environmental factors are long believed to be the dominant contributors to phenotypic diversity in crop plants. However, it has been recently established that, besides genetic variation, epigenetic variation, especially variation in DNA methylation, plays a significant role in determining phenotypic diversity in crop plants. Therefore, assessing DNA methylation diversity in crop plants becomes vital, especially in the case of crops like chickpea, which has a narrow genetic base.
