“…Because of wide adaptability and strong resistance to biotic or abiotic stress (Zhang et al, 2012;Liu and Hua, 2013), wild grapes are an important gene pool for broadening the genetic basis and cultivation of rootstock grapes (Wan et al, 2008;Tian et al, 2008;Heinitz et al, 2019). As a precious germplasm resource, wild grapes play an important role in the Chinese grape industry (Wan et al, 2008;Jiang et al, 2015). In this study, we selected the main wild grape resources in China, including V. amurensis, V. quinquangularis, V. davidii, and V. pseudoreticulata.…”

IntroductionGrape rootstocks play critical role in the development of the grape industry over the globe for their higher adaptability to various environments, and the evaluation of their genetic diversity among grape genotypes is necessary to the conservation and utility of genotypes.MethodsTo analyze the genetic diversity of grape rootstocks for a better understanding multiple resistance traits, whole-genome re-sequencing of 77 common grape rootstock germplasms was conducted in the present study.ResultsAbout 645 billion genome sequencing data were generated from the 77 grape rootstocks at an average depth of ~15.5×, based on which the phylogenic clusters were generated and the domestication of grapevine rootstocks was explored. The results indicated that the 77 rootstocks originated from five ancestral components. Through phylogenetic, principal components, and identity-by-descent (IBD) analyses, these 77 grape rootstocks were assembled into ten groups. It is noticed that the wild resources of V. amurensis and V. davidii, originating from China and being generally considered to have stronger resistance against biotic and abiotic stresses, were sub-divided from the other populations. Further analysis indicated that a high level of linkage disequilibrium was found among the 77 rootstock genotypes, and a total of 2,805,889 single nucleotide polymorphisms (SNPs) were excavated, GWAS analysis among the grape rootstocks located 631, 13, 9, 2, 810, and 44 SNP loci that were responsible to resistances to phylloxera, root-knot nematodes, salt, drought, cold and waterlogging traits.DiscussionThis study generated a significant amount of genomic data from grape rootstocks, thus providing a theoretical basis for further research on the resistance mechanism of grape rootstocks and the breeding of resistant varieties. These findings also reveal that China originated V. amurensis and V. davidii could broaden the genetic background of grapevine rootstocks and be important germplasm used in breeding high stress-resistant grapevine rootstocks.

“…We accessed a set of 19 bioclimate variables with a resolution of 10 arc min for current climate (1950-2000WorldClim, version 1.3) and future climate data (2100, 2 Â CO 2 climate scenarios, CCM3 model from the divagis databases www.diva-gis.org/climate) (Govindasamy et al, 2003), which has been used in many studies (Huang et al, 2019;Jiang et al, 2015;Rodrıguez-Nunez et al, 2021;Yang et al, 2021). To minimize overfitting of the models, we used SPSS 13.0 to calculate the intercorrelations among 19 bioclimatic variables and removed one of the two variables in case a correlation coefficient ≥.85 was obtained.…”

The Yangtze River Basin (YRB), a key biodiversity area and a major economic zone in China, the biodiversity of the area is confronted with severe challenges. In this paper, we analyzed species distribution patterns based on a dataset with 18,538 seed plant species to identify hotspots and evaluate conservation effectiveness and gaps of the YRB. We calculated distribution patterns of species richness with the top 5% richness algorithm and complementarity algorithm, and reconstructed a phylogenetic tree and elucidated spatial phylogenetics. There were 214 hotspot grid cells covering only 6.8% of the study region, but containing 88% seed plant species. Then, we conducted correlation analysis on distribution patterns of different algorithms and species categories, which showed moderate or weak correlations between the top 5% richness algorithm and complementary algorithm. Conservation effectiveness analysis indicated there were 116 hotspot grid cells (accounting for 73.6% of the total species) protected by current conservation networks and there are many conservation gaps remaining. Finally, we used the maximum entropy model (MaxEnt) to predict suitable habitat areas of threatened species under current and future climate scenarios. Prediction analysis results indicated future expansion of suitable habitat to the southeast, and reduction in the central and western portions of the study area. When we considered anthropogenic areas, the suitable habitat was severely decreased, indicating the importance of optimizing the layout of conservation networks and comprehensive biodiversity conservation planning in the YRB.

“…The effects of climate change have been found to impact the distribution range and survival of many species of CWR around the world; the projections are particularly tough for the scenarios based on higher emission of greenhouse gases (RCP 8.5) (Aguirre‐Gutiérrez et al., 2017; Jarvis et al., 2008; Jiang et al., 2015; van Treuren et al., 2017, 2020; Vincent et al., 2019).…”

Climate change is expected to change weather patterns in Chile significantly. Preserving the taxonomic and genetic diversity of crop wild relatives (CWR) is critical to ensure the availability of crops for future human food. However, many CWR are threatened in their natural habitats and underrepresented in gene banks. This research aimed to analyze the current and future climatic suitability under climate change of Chilean endemic CWR, the role of protected areas in their conservation, and possible conflicts of land use with agricultural production. The climatic suitability of 30 species was modeled with present and future bioclimatic variables using a species distribution modeling approach. The climatically suitable areas of all endemic CWR species analyzed are projected to change; 26 increased their suitable areas in the future and four decreased (Ribes integrifolium Phil., Dioscorea fastigiata Gay, Solanum chilense (Dunal) Reiche, Lupinus oreophilus Phil.). Specific conflict with agricultural land use is projected to occur between Valparaiso and Biobio regions, where zones not in protected areas with more than 15 CWR species intersect with those that will be more suitable to produce food crops. Careful and informed planning is required to protect the future distribution of endemic CWR in Chile, especially for species whose climatically suitable area decreases. This effort should comprise a coordinated approach that includes both in situ and ex situ conservation strategies to preserve genetic diversity.
