Social Impact Statement Climate change is expected to disproportionately affect sub‐Saharan Africa in the next century, posing a threat livelihoods of smallholder farmers and deepening food insecurity. To adapt this threat, more climate‐resilient crops need be brought into system; these may developed through breeding with crop wild relatives key traits cope climate change.

Molecular Clocks and Archeogenomics of a Late Period Egyptian Date Palm Leaf Reveal Introgression from Wild Relatives and Add Timestamps on the Domestication

The date palm, Phoenix dactylifera, has been a cornerstone of Middle Eastern and North African agriculture for millennia. It was first domesticated in the Persian Gulf, its evolution appears to have influenced by gene flow from two wild relatives, P. theophrasti, currently restricted Crete Turkey, sylvestris, widespread Bangladesh West Himalayas. Genomes ancient palm seeds show that theophrasti dactylifera may occurred ∼2,200 years ago, but traces sylvestris could not be detected. We here integrate archeogenomics ∼2,100-year-old leaf Saqqara (Egypt), molecular-clock dating, coalescence approaches with population genomic tests, probe hybridization between closest relatives provide minimum maximum timestamps reticulated evolution. shares close genetic affinity populations, we find clear admixture both indicating had contributed genome 2,100 ago. Molecular-clocks placed divergence dactylifera/P. Upper Miocene, strongly supported, conflicting topologies point older dactylifera. Our work highlights hybrid origin palms, prompts investigation functional significance material introgressed which turn prove useful modern breeding.

Modelling potential range expansion of an underutilised food security crop in Sub-Saharan Africa

Environmental Research Letters, Год журнала: 2021, Номер 17(1), С. 014022 - 014022

Abstract Despite substantial growth in global agricultural production, food and nutritional insecurity is rising Sub-Saharan Africa. Identification of underutilised indigenous crops with useful security traits may provide part the solution. Enset ( Ensete ventricosum ) a perennial banana relative cultivation restricted to southwestern Ethiopia, where high productivity harvest flexibility enables it starch staple for ∼20 million people. An extensive wild distribution suggests that much larger region be climatically suitable cultivation. Here we use ensemble ecological niche modelling predict potential range enset within southern eastern We find contemporary bioclimatic suitability 12-fold expansion, equating 21.9% crop land 28.4% population region. Integration diversity, which has broader climate tolerance, could enable 19-fold particularly dryer warmer regions. Whilst change cause 37%–52% reduction by 2070, large centres remain Ethiopian Highlands, Lake Victoria Drakensberg Range. combine our assessment socioeconomic data identify priority areas density, seasonal deficits predominantly small-scale subsistence agriculture, integrating feasible deliver resilience. When incorporating genetic populations, might prove an additional 87.2–111.5 people, 27.7–33 are Ethiopia outside enset’s current range. Finally, consider explanations why not expanded historically, ethical implications expanding previously species.

Societal Impact Statement Drought stress poses a growing threat to food security worldwide. In this study, we investigated the putative drought tolerance traits of enset, multipurpose staple crop endemic Ethiopia that sustains over 20 million people. Our findings reveal enset's domestication has reduced landrace diversity and trait variability, particularly in drier environments, potentially limiting crop's adaptive potential. Farmers arid areas preferentially selected landraces with traits, highlighting vital role indigenous knowledge climate adaptation. By emphasizing importance preserving phenotypic genetic enhance resilience, our study provides globally relevant insights for sustainable agricultural systems under change. Summary Increasing driven by change presents significant challenge global security, requiring adaptations. Indigenous practices drought‐prone may offer effective adaptation strategies. This investigates functional associated reported enset ( Ensete ventricosum ), Ethiopian providing more than Through field surveys farmer interviews along three aridity gradients southwest Ethiopia, determined how cultivation choices have shaped diversity.

Two interesting plants within the Chilean flora (wild and crop species) can be found with a history related to modern fruticulture: Fragaria chiloensis subsp. (Rosaceae) Vasconcellea pubescens (Caricaceae). Both species have wide natural distribution, which goes from Andes mountains sea (East-West), Atacama desert South of Chile (North-South). The growing locations are included Winter Rainfall-Valdivian Forest hotspot. Global warming is great concern as it increases risk losing wild plant species, but at same time, gives chance for usually longer term genetic improvement using naturally adapted material source generating healthy foods.

Cross-Cultural Ethnobotanical Assembly as a New Tool for Understanding Medicinal and Culinary Values–The Genus Lycium as A Case Study

Frontiers in Pharmacology, Год журнала: 2021, Номер 12

Опубликована: Июль 16, 2021

Ethnobotanical knowledge is indispensable for the conservation of global biological integrity, and could provide irreplaceable clues bioprospecting aiming at new food crops medicines. This biocultural diversity requires a comprehensive documentation such intellectual local levels. However, without systematically capturing data, those regional records are fragmented can hardly be used. In this study, we develop framework to assemble cross-cultural ethnobotanical genus level, including species’ their cultural importance, integrating traditional uses, revealing intercultural relationship data quantitatively. Using assembly, medicinal culinary values Lycium evaluated. Simultaneously, analysis highlights problems options systematic assembly. The used here generate baseline relevant sustainable use plant as well within targeting taxa.
