Genomic selection in plant breeding: Key factors shaping two decades of progress

Molecular Plant, Год журнала: 2024, Номер 17(4), С. 552 - 578

Genomic selection, the application of genomic prediction (GP) models to select candidate individuals, has significantly advanced in past two decades, effectively accelerating genetic gains plant breeding.This article provides a holistic overview key factors that have influenced GP breeding during this period.We delved into pivotal roles training population size and diversity, their relationship with population, determining accuracy.Special emphasis was placed on optimizing size.We explored its benefits associated diminishing returns beyond an optimum size.This done while considering balance between resource allocation maximizing accuracy through current optimization algorithms.The density distribution single-nucleotide polymorphisms, level linkage disequilibrium, complexity, trait heritability, statistical machine-learning methods, non-additive effects are other vital factors.Using wheat, maize, potato as examples, we summarize effect these for various traits.The search high GP-theoretically reaching one when using Pearson's correlation metric-is active research area yet far from optimal traits.We hypothesize ultra-high sizes genotypic phenotypic datasets, effective methods support omics approaches (transcriptomics, metabolomics proteomics) coupled deep-learning algorithms could overcome boundaries limitations achieve highest possible accuracy, making selection tool breeding.

Salt-Tolerant Crops: Time to Deliver

Annual Review of Plant Biology, Год журнала: 2023, Номер 74(1), С. 671 - 696

Опубликована: Март 1, 2023

Despite the numerous advances made in our understanding of physiology and molecular genetics salinity tolerance, there have been relatively few applications these to improve salt tolerance crops. The most significant historically utilized intraspecific variation, introgression traits from close crop wild relatives, or, less frequently, more distant relatives. Advanced lines often fail due difficulties or tracking yield penalties associated with alleles nonsaline environments. However, greatest limitation is that not a primary trait for breeders. We must gap between research delivery, especially farmers who precious alternatives. These efforts should include reassessment old techniques such as grafting current crops salt-tolerant hybrid rootstocks. Alternatively, future can be produced via domestication species—an approach now feasible lifetime.

Dissection of a rapidly evolving wheat resistance gene cluster by long-read genome sequencing accelerated the cloning of Pm69

Plant Communications, Год журнала: 2023, Номер 5(1), С. 100646 - 100646

Опубликована: Июль 6, 2023

Gene cloning in repeat-rich polyploid genomes remains challenging. Here we describe a strategy for overcoming major bottlenecks the of powdery mildew (Pm) resistance gene (R-gene) Pm69 derived from tetraploid wild emmer wheat (WEW). A conventional positional approach was not effective due to suppressed recombination. Chromosome sorting compromised by insufficient purity. physical map, constructed assembling Oxford Nanopore Technology (ONT) long-read genome sequences, revealed rapidly evolving nucleotide-binding leucine-rich repeat (NLR) R-gene cluster with structural variations. single candidate NLR identified anchoring RNASeq reads susceptible mutants ONT contigs and validated virus-induced silencing. is likely newly evolved NLR, which discovered only one location across WEW distribution range Israel. successfully introgressed into cultivated wheat, diagnostic molecular marker used accelerate its deployment pyramiding other R-genes.

Plant responses to climate change, how global warming may impact on food security: a critical review

Frontiers in Plant Science, Год журнала: 2024, Номер 14

Опубликована: Янв. 5, 2024

Global agricultural production must double by 2050 to meet the demands of an increasing world human population but this challenge is further exacerbated climate change. Environmental stress, heat, and drought are key drivers in food security strongly impacts on crop productivity. Moreover, global warming threatening survival many species including those which we rely for production, forcing migration cultivation areas with impoverishing environment genetic variability fall out effects security. This review considers relationship climatic changes their bearing sustainability natural ecosystems, as well role omics-technologies, genomics, proteomics, metabolomics, phenomics ionomics. The use resource saving technologies such precision agriculture new fertilization discussed a focus breeding plants higher tolerance adaptability mitigation tools changes. Nevertheless, exposed multiple stresses. study lays basis proposition novel research paradigm referred holistic approach that went beyond exclusive concept yield, included sustainability, socio-economic commercialization, agroecosystem management.

Novel Strategies for Designing Climate‐Smart Crops to Ensure Sustainable Agriculture and Future Food Security

Journal of Sustainable Agriculture and Environment, Год журнала: 2025, Номер 4(2)

Опубликована: Март 31, 2025

ABSTRACT To fulfil food and nutritional demand for nine billion people by the mid‐21st century, global production must increase 60% regardless of challenges such as environmental pollution, water scarcity land degradation. Climate change exacerbates frequency intensity biotic abiotic stresses, which, in turn, severely compromise crop yields, jeopardize supply, deteriorate sustainable development goals achieving safety, limit climate‐smart production. Current consumption practices negatively influence environment, posing a major threat to ecosystem human health. Addressing these critical issues achieve agriculture necessitates designing future crops employing cutting‐edge breeding strategies enhanced productivity with minimal footprints. This endeavour requires comprehensive understanding plant stress adaptation, signalling pathways mitigation mechanisms. In this review, we first explain diverse impacts ongoing climate events on Subsequently, outline various tackle change, including agronomic practices, advanced technologies physiological molecular mechanisms tolerance. We also discuss engineering superior tolerance disease resistance nurturing healthy microbial partnerships between plants soil ensure nutrition security current populations amidst mounting challenges.

How Could the Use of Crop Wild Relatives in Breeding Increase the Adaptation of Crops to Marginal Environments?

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Июнь 16, 2022

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. This review discusses adaptive improve performance strategies deploy them.

Plant diseases caused by diverse pathogens lead to a serious reduction in crop yield and threaten food security worldwide. Genetic improvement of plant immunity is considered as the most effective sustainable approach control diseases. In last decade, our understanding at both molecular genomic levels has improved greatly.
