Application of crop wild relatives in modern breeding: An overview of resources, experimental and computational methodologies

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

Опубликована: Ноя. 17, 2022

Global agricultural industries are under pressure to meet the future food demand; however, existing crop genetic diversity might not be sufficient this expectation. Advances in genome sequencing technologies and availability of reference genomes for over 300 plant species reveals hidden wild relatives (CWRs), which could have significant impacts improvement. There many ex-situ in-situ resources around world holding rare valuable species, carry agronomically important traits it is crucial users aware their availability. Here we aim explore available ex-/in- situ such as genebanks, botanical gardens, national parks, conservation hotspots inventories CWR accessions. In addition highlight advances use genomic resources, contribution pangenome construction introducing novel genes into crops. We also discuss potential challenges modern breeding experimental approaches (e.g. de novo domestication, editing speed breeding) used CWRs computational machine learning) that up utilization programs towards adaptability yield

In situ and ex situ conservation gap analyses of West African priority crop wild relatives

Genetic Resources and Crop Evolution, Год журнала: 2022, Номер 70(2), С. 333 - 351

Опубликована: Дек. 15, 2022

Abstract Crop wild relatives are genetically related taxa of crops with unique resources for crop improvement through the transfer novel and profitable genes. The in situ ex conservation gap analyses priority from West Africa were evaluated using species distribution modelling, ecogeographic diversity, complementary analyses. A total 20, 125 occurrence records used analysis, however, 26 had no data. 64 (62.7%) occurred protected areas, 56 (55%) conserved situ, while 76.7% (43) accessions underrepresented less than 50 situ. Areas highest potential diversity found Woroba Montangnes districts Cote d’Ivoire, Nzerekore, Faranah, Kindia, Boke regions Guinea, South-South, North-East zones Nigeria, Kono Koinadugu Sierra Leone. Hotspots Atlantique, Littoral, Mono, Kouffo, Atakora, Donga, Colline provinces Benin, Accra, Volta Ghana, North–Central Lacs district d’Ivoire Nzerekore region Guinea. 29 reserve sites active identified, 11 occur 18 located outside areas. establishment will complement existing PAs ensure long-term sustainable utilization relative to underpin food security mitigate climate change region.

Modeling the richness and spatial distribution of the wild relatives of Iranian pears (Pyrus L.) for conservation management

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Авг. 6, 2024

The preservation of the genetic resources crop wild relatives (CWRs) is crucial for food production systems and considered a vital measure global agricultural health security. identification potential areas where CWRs can thrive one first steps towards their conservation. In this study, we used maximum entropy model (MaxEnt) to determine habitat suitability seven pears (Pyrus L.) time. We aimed identify high-priority conservation hotspots rich biodiversity in Iran. study showed excellent predictive performance all species studied (AUC value ≥ 90). soil depth, solar radiation, minimum temperature coldest month (Bio6), precipitation wettest quarter (Bio16) were main environmental factors that influenced species, according permutation importance. projected maps revealed P. elaeagnifolia had largest suitable area, while glabra lowest. results also less than 5% habitats these protected areas. This research highlights need national policies development cultivation rehabilitation strategies threatened species.

Опубликована: Сен. 15, 2022

The scientific assessment of the health level county ecosystems is basis for formulating county-based sustainable development strategies. In this paper, we take areas Sichuan Province as evaluation objects and combine SDGs (the Sustainable Development Goals) to establish a ecosystem index system based on VORS (Vigor–Organization–Resilience–Service) model. On basis, used entropy weight method, Moran obstacle degree model analyze level, spatial distribution characteristics, obstacles 183 counties in Province. main results were follows: (1) A total 80.87% at sub-healthy healthy levels, concentrated southeastern part Sichuan, 19.13% an unhealthy mainly Aba, Ganzi, Liangshan areas. (2) levels had high autocorrelation characteristics. H–H (High–High) agglomeration area L–L (Low–Low) significant which distributed Cheng-Mian northwestern area, respectively. (3) key indicators restricting urban are economic vitality, resilience, quality life, all belong subsystems, with reaching 17.25%, 16.68%, 13.52%, This study can provide theoretical methodological support research into evaluations decision-making promoting coordinating regional

Sundaland ecosystems are under threat from human activity and climate change such as logging, agricultural practices, overexploitation of wildlife climatic that have led to frequent forest fires a decline in indigenous plant animal species. This study investigates the risks Sundaland's biodiversity well management possibilities using GIS, RS, AI. The goal was find out how artificial intelligence (AI) can be applied effectively manage expand on body knowledge already available about useful roles GIS RS play area. In this systematic method, seven databases were used gather data 110 research publications, which 101 screened for scope subject variable. 80% (81articles) examined studies collected RS. It is found that. AI poised grow, offering new opportunities address intricate challenges facing our planet's diverse ecosystems. conclusion, efficient monitoring, well-informed policy creation, decision-making guarantee long-term preservation biodiversity, integration essential.

Sustainable Agricultural Practices for the Production of Aromatic and Medicinal Plants: Evidences and Recommendations

Опубликована: Июль 20, 2023

As the demand for aromatic and medicinal herbs increases, so does pressure to intensify production, increasing risk of overexploitation these natural resources. Sustainability corresponds preservation something that exists in present must be maintained future, implying accountability obligation. However, order maintain conditions essential goods survival future generations, consumers businesses commit sustainable practices. The circular economy is considered one solutions promote a system can defined as transition from linear model, where resources are transformed, used discarded, (regenerative) materials reused whenever possible. An ecologically correct approach waste reuse avoids negative impacts associated with improper disposal agro-industrial wastes, such mass proliferation microorganisms, production greenhouse gases, loss energy potential, other on environment or human health. objective this study provide compilation good agricultural practices sustainability herbs, particularly areas cultivation, harvesting, drying, extraction, packaging, highlight potential evaluating processing residues herbs.

Опубликована: Июнь 2, 2022

Sustainable conservation of crop wild relatives is one the pathways to securing global food security amid climate change threats biodiversity. However, their partly limited by spatio-temporal distribution knowledge gaps mostly because they are not morphologically charismatic species attract attention. Therefore, contribute planning relatives, this study assessed present-day and predicted potential effect on 15 Vigna relative taxa in Benin under two future scenarios (RCP 4.5 RCP 8.5) at 2055-time horizon. MaxEnt model, occurrence records, a combination climate- soil-related variables were used. The model performed well (AUC, mean = 0.957; TSS, 0.774). showed that (i) precipitation driest quarter isothermality dominant environmental influencing Benin; (ii) about half total land area was potentially suitable habitat studied present climate; (iii) nearly one-third may shift ranges northwards lose habitats 5 40% 2055 due change; (iv) existing protected network ineffective conserving current or climatic conditions, as it covered only 10% species. concludes will have both negative positive effects suitability such use areas alone be best option conserve diversity. Integrating multiple situ ex approaches taking into account “other effective area-based measures” recommended. This provides crucial step towards development sustainable strategies for West Africa.
