Abstract Chenopodium quinoa (quinoa) is a highly nutritious grain identified as an important crop to improve world food security. Unfortunately, few resources are available facilitate its genetic improvement. Here we report the assembly of high-quality, chromosome-scale reference genome sequence for quinoa, which was produced using single-molecule real-time sequencing in combination with optical, chromosome-contact and maps. We also two diploids from ancestral gene pools enables...
Despite the central importance of noncoding DNA to gene regulation and evolution, understanding extent selection on plant remains limited compared that other organisms. Here we report sequencing genomes from three Brassicaceae species (Leavenworthia alabamica, Sisymbrium irio Aethionema arabicum) their joint analysis with six previously sequenced crucifer genomes. Conservation across orthologous bases suggests at least 17% Arabidopsis thaliana genome is under selection, nearly one-quarter...
A halophyte refers to a plant that can naturally tolerate high concentrations of salt in the soil, and its tolerance stress may occur through various evolutionary molecular mechanisms. Eutrema salsugineum is one halophytic species Brassicaceae family multiple types abiotic stresses typically limit crop productivity, such as extreme salinity cold. It has been widely used laboratorial model for biology research plants. Here, we present reference genome sequence (241 Mb) E. at 8x coverage...
Abstract The genus Chenopodium L. is characterized by its wide geographic distribution and ecological adaptability. Species such as quinoa ( Willd.) have served domesticated staple crops for centuries. Wild species exhibit diverse niche adaptations are important genetic reservoirs beneficial agronomic traits, including disease resistance climate hardiness. To harness the potential of wild taxa crop improvement, we developed a pangenome through assembly comparative analyses 12 that encompass...
Amaranth (Amaranthus hypochondriacus) was a food staple among the ancient civilizations of Central and South America that has recently received increased attention due to high nutritional value seeds, with potential help alleviate malnutrition security concerns, particularly in arid semiarid regions developing world. Here, we present reference-quality assembly amaranth genome which will assist agronomic development species. Utilizing single-molecule, real-time sequencing (Pacific...
Chenopodium quinoa (quinoa) is an emerging crop that produces nutritious grains with the potential to contribute global food security. Quinoa can also grow on marginal lands, such as soils affected by high salinity. To identify candidate salt tolerance genes in recently sequenced genome, we used a multifaceted approach integrating RNAseq analyses comparative genomics and topology prediction. We identified 219 selecting those were differentially expressed response salinity, specific or...
Eutrema salsugineum and Schrenkiella parvula are salt-tolerant relatives of the salt-sensitive species Arabidopsis thaliana. An important component salt tolerance is regulation Na+ ion homeostasis, which occurs in part through proteins encoded by Cation/Proton Antiporter-1 (CPA1) gene family. We used a combination evolutionary functional analyses to examine role CPA1 genes E. Sc. parvula, found evidence that changes CPA1-mediated extrusion may contribute both species. Specifically, we member...
Summary Although peroxisomes play a key role in plant metabolism under both normal and stressful growth conditions, the impact of drought heat stress on remains unknown. Quinoa represents an informative system for dissecting abiotic peroxisome proliferation because it is adapted to marginal environments. Here we determined correlation abundance with physiological responses yield heat, plus stresses eight genotypes quinoa. We found that all caused reduction stomatal conductance yield....
Abstract Quinoa ( Chenopodium quinoa Willd.) is an allotetraploid seed crop with the potential to help address global food security concerns. Genomes have been assembled for four accessions of quinoa; however, all assemblies are fragmented and do not reflect known chromosome biology. Here, we use in vitro vivo Hi-C data produce a chromosome-scale assembly Chilean accession PI 614886 (QQ74). The final spans 1.326 Gb, which 90.5% into 18 scaffolds. genome annotated 54,499 protein-coding genes,...
Quinoa has recently gained international attention because of its nutritious seeds, prompting the expansion cultivation into new areas in which it was not originally selected as a crop. Improving quinoa production these will benefit from introduction advantageous traits free-living relatives that are native to these, or similar, environments. As part an ongoing effort characterize primary and secondary germplasm pools for quinoa, we report complete mitochondrial chloroplast genome sequences...
Abstract Pitseed goosefoot ( Chenopodium berlandieri ) is a free-living North American member of an allotetraploid complex that includes the Andean pseudocereal quinoa C. ). Like quinoa, pitseed was domesticated, possibly independently, in eastern America (subsp. jonesianum and Mesoamerica nuttaliae To test utility as resource for breeding, we produced whole-genome DNA sequence PI 433,231, huauzontle from Puebla, México. The 1.295 Gb genome assembled into 18 pseudomolecules annotated using...
Understanding how leaf morphology mediates plant responses to environmental variation is essential for predicting species adaptability under climate change. In this study, we investigated natural in shape and associated functional physiological traits (FPTs) across populations of Chenopodium hircinum grown a common garden. We found that strongly correlates with the climatic conditions population provenance, while are independently rather than directly climate. Landmark-based morphometric...
Chenopodium quinoa (quinoa) is considered a superfood with its favourable nutrient composition and being gluten free. Quinoa has high tolerance to abiotic stresses, such as salinity, water deficit (drought) cold. The mechanisms are yet be elucidated. epidermal bladder cells (EBCs) that densely cover the shoot surface, particularly younger parts of plant. Here, we report on EBC's primary secondary metabolomes, well lipidome in control conditions response stresses. EBCs were isolated from...

It an A-genome diploid (2n = 2x 18) relative allotetraploid (AABB) Chenopodium quinoa and shares many its nutritional benefits. seed contains complete protein, low glycemic index, offers wide variety nutritionally important vitamins minerals.The reference assembly was developed using combination short- long-read sequencing techniques, including multiple rounds Hi-C-based proximity-guided assembly.The final...
Abstract Djulis (Chenopodium formosanum Koidz.) is a crop grown since antiquity in Taiwan. It BCD-genome hexaploid (2n = 6x 54) domesticated form of lambsquarters (C. album L.) and relative the allotetraploid (AABB) C. quinoa. As with quinoa, djulis seed contains complete protein profile many nutritionally important vitamins minerals. While still sold locally Taiwanese markets, its traditional culinary uses are being lost as diets younger generations change. Moreover, indigenous peoples who...
Summary To optimize shoot growth and structure of cereals, we need to understand the genetic components controlling initiation elongation. While measuring total at high throughput using 2D imaging has progressed, recovering 3D small grain cereals a large scale is still challenging. Here, present method for defined individual leaves such as wheat barley, few images. Plant modelling over time was used measure elongation in bi‐parental barley mapping population under low soil salinity. We...
