The domestication of grain crops is among the most important phenomena to facilitate humanity’s cultural development, and seed size increases are taken as one earliest traits. Much remains unknown about ecological drivers mechanisms surrounding this trait, but morphometric analyses have been crucial investigate topic for decades. Measurements on ancient cereal grains show that they evolved produce larger seeds in their region origin prior dispersing beyond progenitor range. This paper takes a transcontinental (Europe Asia), long-term approach comparative data. Unpublished measurements from over 10 sites barley, free-threshing wheat, broomcorn millet, foxtail millet Central Asia China collected study. We contrasted these with published data Europe, southwest Central, East South Asia. whether cereals parallel or divergent ways across different lineages after dispersed centres origin; we trace changes initial cultivation through spread eventual adaptation novel environments. analysis allows us discuss rates evolution highlight evolutionary trends within some Eurasian continent. article part theme issue ‘Unravelling domestication: multi-disciplinary perspectives human non-human relationships past, present future’.

Genetic dissection of natural variation in oilseed traits of camelina by whole‐genome resequencing and QTL mapping

The Plant Genome, Год журнала: 2021, Номер 14(2)

Опубликована: Июнь 9, 2021

Abstract Camelina [ sativa (L.) Crantz] is an oilseed crop in the Brassicaceae family that currently being developed as a source of bioenergy and healthy fatty acids. To facilitate modern breeding efforts through marker‐assisted selection biotechnology, we evaluated genetic variation among worldwide collection 222 camelina accessions. We performed whole‐genome resequencing to obtain single nucleotide polymorphism (SNP) markers analyze genomic diversity. also conducted phenotypic field evaluations two consecutive seasons for variations key agronomic traits related production such seed size, oil content (OC), acid composition, flowering time. determined population structure accessions using 161,301 SNPs. Further, identified quantitative trait loci (QTL) candidate genes controlling above field‐evaluated by genome‐wide association studies (GWAS) complemented with linkage mapping recombinant inbred line (RIL) population. Characterization natural at genome levels provides valuable resources improvement. The QTL should assist advanced varieties can be integrated into cropping systems high yield oils desired composition.

Societal Impact Statement Sorghum is an important cereal crop that provides calories and nutrients for much of the world's population, it often grown with low fertiliser input. Optimising yield, nutritive content bioavailability sorghum grain minimal input importance human nutrition, arbuscular mycorrhizal (AM) fungi have previously shown potential to assist in this. Across genetic diversity, AM improved nutrition zinc iron a phosphorus soil. Thus, food production systems effectively manage may improve consumer outcomes. Summary C 4 source across world, predominantly cultivated consumed low‐ middle‐income countries. can be highly colonised by fungi, plant‐fungal association lead improvements biomass nutrient uptake. High‐throughput phenotyping allows us non‐destructively interrogate ‘hidden’ effects on growth phenology. Eight genetically diverse genotypes were soil amended 2 or 20 mg P kg −1 inoculated fungal culture Rhizophagus irregularis . uncovered phenology, while biomass, Zn Fe root colonisation was determined after destructive harvest. plants generally performed better than non‐AM control plants, greater harvest indices, P, contents.

Genetic Architecture of Grain Yield-Related Traits in Sorghum and Maize

International Journal of Molecular Sciences, Год журнала: 2022, Номер 23(5), С. 2405 - 2405

Опубликована: Фев. 22, 2022

Grain size, grain number per panicle, and weight are crucial determinants of yield-related traits in cereals. Understanding the genetic basis has been main research object nodal crop science. Sorghum maize, as very close C4 crops with high photosynthetic rates, stress tolerance large biomass characteristics, extensively used to produce food, feed, biofuels worldwide. In this review, we comprehensively summarize a quantitative trait loci (QTLs) associated yield sorghum maize. We placed great emphasis on discussing 22 fine-mapped QTLs 30 functionally characterized genes, which greatly hinders our deep understanding at molecular mechanism level. This review provides general overview comprehensive findings discusses emerging trend marker-assisted breeding these QTLs.

Опубликована: Фев. 10, 2022

Abstract Potato is the fourth most important food crop in world. Although with a long history for breeding approaches, genomic information and association between genes agronomic traits remain largely unknown particularly autotetraploid potato cultivars, which limit molecular progression. By resequencing genome of 108 main cultivar accessions rich genetic diversity population structure from International Center, approximate 20-fold coverage, we revealed more than 27 million Single Nucleotide Polymorphisms ~ 3 Insertion Deletions high quality accuracy. Domestication analysis genome-wide studies (GWAS) identified candidate loci related to photoperiodic flowering time temperature sensitivity as well disease resistance, providing informative insights into selection domestication potato. In addition, GWAS GWASploy 25 by signals, especially those tuber size, small-sized weight thickness that was also validated transcriptome analysis. Our study provides valuable resource facilitates elucidation process improvement

Elevated [CO2] negatively impacts C4 photosynthesis under heat and water stress without penalizing biomass

Journal of Experimental Botany, Год журнала: 2023, Номер 74(9), С. 2875 - 2890

Опубликована: Фев. 17, 2023

Elevated [CO2] (eCO2) and water stress reduce leaf stomatal conductance (gs), which may affect thermoregulation during heat waves (heat stress). Two sorghum lines, with different width were grown in a glasshouse at mean day temperature of 30 °C, under watering levels, subjected to (43 °C) for 6 d the start reproductive stage. We measured photosynthetic responses light transients before harvesting plants. Photosynthesis growth conditions (Agrowth) biomass accumulation enhanced by eCO2 control conditions. Heat increased gs, especially wider leaves, reduced time constant opening (kopen) ambient but not eCO2. However, photosynthesis due evaporative cooling. prevented reduction both stress, possibly improved plant soil status as result gs. Our results suggest that response C4 crop future climate depends on trade-off between low gs needed high use efficiency drought tolerance, tolerance an future.

Plant and Cell Physiology, Год журнала: 2020, Номер 61(7), С. 1262 - 1272

Опубликована: Апрель 22, 2020

Abstract Sorghum [Sorghum bicolor (L.) Moench] grown locally by Japanese farmers is generically termed Takakibi, although its genetic diversity compared with geographically distant varieties or even within Takakibi lines remains unclear. To explore the genomic and traits controlling biomass other physiological in we focused on a landrace, NOG, this study. Admixture analysis of 460 sorghum accessions revealed that NOG belonged to subgroup represented Asian sorghums, it was only distantly related American/African including BTx623. In an attempt dissect major biomass, generated recombinant inbred line (RIL) from cross between BTx623 constructed high-density linkage map based 3,710 single-nucleotide polymorphisms obtained restriction-site-associated DNA sequencing 213 RIL individuals. Consequently, 13 fine quantitative trait loci (QTLs) were detected chromosomes 2, 3, 6, 7, 8 9, which included five QTLs for days heading, three plant height (PH) total shoot fresh weight two Brix. Furthermore, identified dominant PH as being identical previously reported dw1 dw3. Together, these results corroborate diversified genome while population study will be useful dissecting important sorghum.
