Biocultural diversity is the ever-evolving and irreplaceable sum total of all living organisms inhabiting Earth. It plays a significant role in sustainable productivity ecosystem services that benefit humanity closely allied with human cultural diversity. Despite its essentiality, biodiversity seriously threatened by insatiable inequitable exploitation Earth's resources. One benefits utilization crop improvement, including cropping improvement (agronomic cultivation practices) genetic (plant breeding). Crop has tended to decrease agricultural since origins agriculture, but awareness this situation can reverse negative trend. Cropping strive use more diverse cultivars broader complement crops on farms landscapes. also focus underutilized crops, legumes. Genetic access range sources and, assistance modern breeding tools like genomics, facilitate introduction additional characteristics improve yield, mitigate environmental stresses, restore, at least partially, lost biodiversity.

Abstract The interplay between nuclear and cytoplasmic genomes—collectively known as cytonuclear interactions (CNIs)—is increasingly recognized a key driver of phenotypic variation adaptive potential across diverse organisms. Yet, leveraging diversity fully understanding CNIs’ contributions to agriculturally important traits remain major challenges in crop improvement, largely due the scarcity tailored genetic resources. In cultivated barley ( Hordeum vulgare ), limited relative its wild relatives constrains adaptability changing environments. While germplasm offers reservoir valuable alleles, role CNIs shaping complex is still poorly understood. To address this gap, we present Cytonuclear Multi-Parent Population (CMPP)—a novel interspecific resource comprising 951 BC 2 DH lines, generated from crosses ten genetically accessions H. ssp. spontaneum ) used female founders elite cultivar Noga. This design facilitates concurrent segregation analysis introgressions involving distinct versus backgrounds subfamilies. Phenotyping multiple environments revealed that up 5% spike grain trait BLUPs are explained by cytoplasm (η² = 0.05), including Thousand Grain Weight (TGW), Width (GW), Fruiting Efficiency at Maturity (FEm). Notably, cytoplasms influenced stability, with B1K-50-04 increasing TGW stability based on Shukla’s measure. Genome-wide association studies (GWAS) employing Nested Association Mapping (NAM), FASTmrMLM, MatrixEpistasis (ME) identified 76 marker-trait associations (MTAs). ME approach specifically uncovered 16 QTL (cnQTL) exhibiting cytoplasm-dependent effects. Furthermore, developed genomic prediction (GP) strategy incorporating significant MTAs population structure variables (subfamily cytoplasm). targeted interaction model (“Peaks + I”) achieved cross-validation accuracies comparable to, or even exceeding, models using full set 6,679 SNPs, despite utilizing substantially fewer predictors, enabling quicker more efficient validation runs. CMPP provides unique platform for dissecting effects CNIs, highlighting importance context mapping effectively harness both improvement.

Plant factories, being more weather independent, can potentially contribute to global food security under climate change scenarios, but their profitability and environmental sustainability are debatable. This study quantitatively assessed the business life-cycle-based carbon footprint of a hypothetical plant factory. A system dynamics model was constructed simulate yearly profit warming potential (GWP) 2-ha farm over 20 years using experimental data from growing 397 Brassica oleracea 204 Eruca sativa accessions in prototype factory Singapore. Experimentally derived parameters include resource-use data, maximum yield improvement, effect increasing planting density on yield. Model simulations predicted that with accession-wide average (status quo), would meet 0.8 % leafy vegetable requirement population earn negative profit.

Abstract Plant conservation hinges on preserving biodiversity, which is crucial for long-term adaptation. Multiple studies have reported genetic evidence of crop-to-wild introgression in phenotypically wild accessions barley ( Hordeum vulgare ssp. spontaneum ). We examined 318 Wild Barley Diversity Collection (WBDC) from cultivated barley. Using SNP genotype and exome capture data, we performed local ancestry inference between the WBDC to identify genomic regions with introgression. intervals well-characterized genes involved domestication improvement, at potentially important maintaining a phenotype. Our analysis revealed that nearly 16% (48 318) showed barley, up 16.6% genome has been introgressed. All identified as introgressed based domestication-related phenotypes show clear The size runs identity by state suggests most did not occur recently. This study long history exchange highlighting potential influence makeup future adaptation populations, implications plant strategies.

Abstract Modern domestication efforts have occurred in a wide range of species. These led to different levels change from the initial wild populations and market success. In this study, we explore breeding cycle parameters understand rate potential starting points neo‐domestication programs. The design program that will bring new crop requires consideration cost efficiency resource allocation. More diversity on creates an opportunity types food systems can be tailored toward regional local security. Stochastic simulation gain variance is applied parameter combinations through cycle—crossing, evaluation, selection—to identify population level changes along continuum semi‐domestic plant simulated schemes differ phenotypic depending selection strategy type, discovering largest oligogenic traits occurring using recurrent for landrace orphan while choosing genomic populations. There were also differences based strategy, with maximum avoidance consistently leading lower gains but higher additive variance. Overall, when looking domesticate species, our simulations find most cost‐effective option lead early generations selection, marker technology being useful once plateaued.

Lettuce (Lactuca sativa L.) is a source of beneficial compounds though they are generally present in low quantities. We used 40K Axiom and 9K Infinium SNP (single nucleotide polymorphism) arrays to (i) explore the genetic variability 21 varieties (ii) carry out genome-wide association studies (GWAS) vitamin C content in21 population 205 plants from richest variety ('Lechuga del Pirineo'). Structure phylogenetic analyses showed that group formed mainly by traditional was most diverse, whereas red commercial clustered together very distinguishably apart rest. GWAS consistently detected, region chromosome 2, several SNPs related dehydroascorbic acid (a form C) using three different methods assess structure, subpopulation membership coefficients, multidimensional scaling, principal component analysis. The latter detected highest number (17) significantly associated, 12 them showing high linkage disequilibrium with lead SNP. Among 84 genes region, some have been reported be or antioxidant status other crops either directly, like those encoding long non-coding RNA, F-box proteins, pectinesterase/pectinesterase inhibitor, indirectly, extensin-1-like protein endoglucanase 2 genes. involvement identified within levels needs further studied. Understanding control such an important quality trait lettuce becomes relevant breeding perspective.
