Fig. 2: Geographic locations and candidate regions responsive to high-altitude extremes.
From: Origin and adaptation to high altitude of Tibetan semi-wild wheat

a Global distribution of wheat accessions. NCL, Non-Chinese landrace; NCC, Non-Chinese cultivar; CL, Chinese landrace (excluding Tibetan landrace); CC, Chinese cultivar; TS, Tibetan semi-wild wheat; TL, Tibetan landrace. b Genome-wide distribution of genetic differentiation regions between high-altitude (HA) and low-altitude (LA) wheat accessions identified by FST analysis. Each point indicates a 100k-bp window. Dashed lines indicate the top 5% thresholds. Key candidate genes are labeled with arrows. c Geographic distribution of different haplotypes of TaHY5-like gene. The haplotype distribution analysis was determined using 308 resequencing accessions and 1026 wheat whole-exome capture samples. Orange indicates the proportion of HA adapted haplotype of TaHY5-like gene. HA, high-altitude wheat accessions. LA, low-altitude accessions. Geographic maps in a and c were generated using R packages, including maps, ggmaps, ggplot2, and sf, with geographic information data edited from original version of the Natural Earth project database (version 2013).
