Crop wild relatives (CWRs) have provided breeders with several 'game-changing' traits or genes that boosted crop resilience and global agricultural production. Advances in breeding genomics accelerated the identification of valuable CWRs for use improvement. The enhanced genetic diversity pools carrying optimum combinations favorable alleles targeted crop-growing regions is crucial to sustain gain. In parallel, growing sequence information on genomes combination precise gene-editing tools provide a fast-track route transform into ideal future crops. Data-informed germplasm collection management strategies together adequate policy support will be equally important improve access their sustainable meet food nutrition security targets.

Disease-resistance (R) gene cloning in wheat (Triticum aestivum) has been accelerated by the recent surge of genomic resources, facilitated advances sequencing technologies and bioinformatics. However, with challenges population growth climate change, it is vital not only to clone functionally characterize a few handfuls R genes, but also do so at scale that would facilitate breeding deployment crops can recognize wide range pathogen effectors threaten agroecosystems. Pathogen populations are continually changing, breeders must have tools resources available rapidly respond those changes if we safeguard our daily bread. To meet this challenge, propose creation R-gene atlas an international community researchers breeders. The consist online directory from which sources resistance could be identified deployed achieve more durable major pathogens, such as rusts, blotch diseases, powdery mildew, blast. We present costed proposal detailing how interacting molecular components governing disease captured both host through biparental mapping, mutational genomics, whole-genome association genetics. explore options for configuration genotyping diversity panels hexaploid tetraploid wheat, well their wild relatives discuss inform dynamic, approach deployment. Set against current magnitude yield losses worldwide, recently estimated 21%, endeavor presents one route bringing genes lab field considerable speed quantity.

Climate change during the last 40 years has had a serious impact on agriculture and threatens global food nutritional security. From over half million plant species, cereals legumes are most important for Although systematic breeding relatively short history, conventional coupled with advances in technology crop management strategies increased yields by 56 % globally between 1965−85, referred to as Green Revolution. Nevertheless, demand food, feed, fiber, fuel necessitates need break existing yield barriers many plants. In first decade of 21st century we witnessed rapid discovery, transformative technological development declining costs genomics technologies. second decade, field turned towards making sense vast amount genomic information subsequently moved accurately predicting gene-to-phenotype associations tailoring plants climate resilience this review focus resources, genome germplasm sequencing, sequencing-based trait mapping, genomics-assisted approaches aimed at developing biotic stress resistant, abiotic tolerant high nutrition varieties six major (rice, maize, wheat, barley, sorghum pearl millet), (soybean, groundnut, cowpea, common bean, chickpea pigeonpea). We further provide perspective way forward use including marker-assisted selection, backcrossing, haplotype based prediction machine learning artificial intelligence, speed approaches. The overall goal is accelerate genetic gains deliver resilient sustainable agriculture.

Alongside the use of fertilizer and chemical control weeds, pests, diseases modern breeding has been very successful in generating cultivars that have increased agricultural production several fold favorable environments. These typically homogeneous (either homozygous inbreds or hybrids derived from inbred parents) are bred under optimal field conditions perform well when there is sufficient water nutrients. However, such rare globally; indeed, a large proportion arable land could be considered marginal for production. Marginal poor fertility and/or shallow soil depth, subject to erosion, often occurs semi-arid saline Moreover, these environments expected expand with ongoing climate change progressive degradation resources globally. Crop wild relatives (CWRs), most used as sources biotic resistance, also possess traits adapting them Wild progenitors selected over course their evolutionary history maintain fitness diverse range stresses. Conversely, broad adaptation reduced genetic diversity vulnerability abiotic challenges. There potential exploit heterogeneity, opposed uniformity, utilization lands.

Major crops are all survivors of domestication bottlenecks. Studies have focused on the genetic loci related to syndrome, while contribution ancient haplotypes remains largely unknown. Here, an ancestral genomic haploblock dissection method is developed and applied a resequencing dataset 386 tetraploid/hexaploid wheat accessions, generating pan-ancestry map. Together with cytoplastic evidences, we reveal that domesticated polyploid emerged from admixture six founder wild emmer lineages, which contributed foundation mosaics. The key domestication-related loci, originated over wide geographical range, were gradually pyramided through protracted process. Diverse stable-inheritance haplotype groups chromosome central zone identified, revealing expanding routes trends modern breeding. Finally, evolution model proposed, highlighting role wild-to-crop interploidy introgression, increased diversity following bottlenecks introduced by polyploidization.
