“…It has three main qualities. First, buckwheat grows well on poor soils, does not need fertilizers or biocides (Sharma, 1986; Myers and Meinke, 1994; Campbell, 1997; Small, 2017). It is sustainable for organic and environmental‐friendly farming (Small, 2017).…”

“…Second, buckwheat belongs to the Polygonaceae family and is a pseudocereal with high nutritional qualities (Myers and Meinke, 1994; Campbell, 1997; Small, 2017). Seeds are rich in lysine, dietary fibers, minerals, and are gluten‐free (Campbell, 1997; Alvarez‐Jubete et al, 2010) and can be used as Poaceae seeds (Sharma, 1986; Campbell, 1997; Small, 2017). Third, buckwheat is recognized for its medicinal qualities.…”

“…The two species differ for their reproduction. F. esculentum is a self‐incompatible species mainly pollinated by insects (Sharma, 1986; Campbell, 1997; Miljuš‐Đukić et al, 2010). It produces two morphs of flowers: pin and thrum flowers.…”

Water availability is one of the main factors affecting crop production and the occurrence of drought periods is expected to increase in the context of ongoing climate change. We investigated the impact of water stress on two pseudocereal species, common buckwheat (Fagopyrum esculentum) and Tartary buckwheat (Fagopyrum tataricum). Plants were grown under greenhouse conditions under two water regimes: control (40-50% soil humidity) and water stress (<20% soil humidity). Although closely related, both species differed by their resistance to water stress. The vegetative growth was affected in F. esculentum but not in F. tataricum as water stress decreased leaf production, leaf fresh, and dry weight, stomatal conductance, transpiration rate, and photosynthesis rate in the former but not in the latter. However, chlorophyll fluorescence parameters were not affected by water stress, whatever the species, and the chlorophyll content increased in water-stressed plants in both species.Oxidative stress was observed in both species in response to water stress, and antioxidant content was increased in F. tataricum. The reproductive phase was affected by water stress in both species: the number of inflorescences and pollen production decreased, mainly in F. esculentum. Seed set was maintained in F. tataricum while this parameter was not investigated in F. esculentum due to its self-incompatibility. Our results suggested that F. tataricum was more resistant to water stress than F. esculentum and that F. esculentum had characteristics of drought avoidance, while F. tataricum exhibited traits of drought tolerance. | INTRODUCTIONIn the face of climate change, extreme events, such as drought are expecting to become more frequent and more intense (IPCC, 2014). It will have many negative impacts on crop production. Indeed, water availability is one of the main factors impacting crop production (Barnabás et al., 2008;Gray and Brady, 2016). When the water supply is inferior to the water demand, plants encounter water stress (Salehi-Lisar and Bakhshayeshan-Agdam, 2016). Water stress can have many impacts on plants at every life stage. It can decrease the germination rate (

We present a species distribution model (SDM) of Fagopyrum esculentum (buckwheat) in China using present distribution data and estimates for the past based on palaeoclimatic reconstructions. Our model estimates the potential area suitable for buckwheat cultivation over the last 8,000 years, with northeast China consistently showing the highest suitability, providing insights on the discrepancy between the location of the earliest archaeobotanical records in the area and its origins in southwest China based on biogeographic and genetic data. The model suggests little to no variation over time in the spatial extent of the potential area suitable for buckwheat cultivation. In the northern parts of China, the limits of the ecological niche largely fall within the borders of the study area, while to the west it never extends into the main Tibetan plateau, explaining the lack of fossil evidence from Central Asia. In the southwest, the niche overlaps with the borders of modern China, which supports this direction as a viable route of westward dispersal. The comparison between the prediction from the model and sites with archaeobotanical evidence for Fagopyrum indicates that the environmental niche it occupied remained stable over time. This may contrast with a dispersal pattern characterised by continuous adaptations to new environments facilitated by human activity, which may be suggested for other major and minor crops.
