Advances in DNA sequencing technology have sparked a genomics revolution, driving breakthroughs plant genetics and crop breeding. Recently, the focus has shifted from cataloging genetic diversity plants to exploring their functional significance delivering beneficial alleles for improvement. This transformation been facilitated by increasing adoption of whole-genome resequencing. In this review, we summarize current progress population-based genome resequencing studies how these affect A total 187 land 163 countries resequenced, comprising 54 413 accessions. As part efforts 367 traits surveyed 86 genome-wide association conducted. Economically important crops, particularly cereals, vegetables, legumes, dominated efforts, leaving gap 49 orders, including Lycopodiales, Liliales, Acorales, Austrobaileyales, Commelinales. The resequenced germplasm is distributed across diverse geographic locations, providing global perspective on genomics. We highlight genes that selected during domestication, or associated with agronomic traits, form repository candidate future research application. Despite opportunities cross-species comparative genomics, many population genomic datasets are not accessible, impeding secondary analyses. call more open collaborative approach promotes data sharing encourages contribution-based credit policy. number will continue rise decreasing costs, coupled advances analysis computational technologies. expansion, terms both scale quality, holds promise deeper insights into trait breeding design.

The recent Russia–Ukraine conflict has raised significant concerns about global food security, leaving many countries with restricted access to imported staple crops, particularly wheat and sunflower oil, sending prices soaring other adverse consequences in the supply chain. This detrimental effect is prominent for low-income relying on grain imports, record-high inflation affecting their livelihoods. review discusses role of Russia Ukraine system impact security. It also highlights how diversifying four areas agrifood systems—markets, production, technology can contribute achieving chain resilience future security sustainability.

The availability of multiple sequenced genomes from a single species made it possible to explore intra- and inter-specific genomic comparisons at higher resolution build clade-specific pan-genomes several crops. crops constructed various cultivars, accessions, landraces, wild ancestral represent compendium genes structural variations allow researchers search for the novel alleles that were inadvertently lost in domesticated during historical process crop domestication or extensive plant breeding. Fortunately, many valuable associated with desirable traits like disease resistance, abiotic stress tolerance, architecture, nutrition qualities exist species, relatives. ancestors landraces can be introduced back high-yielding varieties modern by implementing classical breeding, selection, transgenic/gene editing approaches.

Crop production is becoming an increasing challenge as the global population grows and climate changes. Modern cultivated crop species are selected for productivity under optimal growth environments have often lost genetic variants that could allow them to adapt diverse, now rapidly changing, environments. These present in their closest wild relatives, but so less desirable traits. How preserve effectively utilize rich resources relatives offer while avoiding detrimental maladaptive contributions a central ongoing improvement.

The Mediterranean region’s harsh conditions, characterized by low rainfall, high solar radiation, and elevated temperatures, pose challenges for vegetation, particularly in the face of climate change. Cultivated olive ( Olea europaea subsp. var. ) holds historical economic significance as one oldest crops Mediterranean. Due to their germplasm diversity greater flowering abundance compared offspring cultivated olives, wild olives sylvestris could be utilized selecting new cultivars capable adapting a changing climate. This research aimed compare effects salt drought stress on genotypes analyzing morphological, physiological, biochemical parameters. Results showed that shoot length, dry mass, leaf area are key indicators trees. results indicated trees more susceptible salinity had lower Na + Cl - concentrations leaves took longer stabilize ion levels.

Crop wild relatives (CWRs) - plant taxa genetically closely related to domesticated plants are considered an alternative pathway solving global food insecurity in a changing climate.
