A natural variation in the HSP90.2 promoter enhanced its function and increased wheat yield. (a) The schematic presentation and distribution of tandem single nucleotide polymorphisms (SNPs) in the promoter region of the HSP90.2 gene. (b) The accumulation of cytosolic HSP90 protein in RIL lines with Hsp90.2‐B‐HapI or Hsp90.2‐B ‐HapII. (c, d) Comparison of transcriptional level (c) or protein contents (d) in Hsp90.2‐B‐HapI or Hsp90.2‐B‐HapII RIL lines. (e–f) The net photosynthesis rates and chlorophyll contents in the flag leaf at the grain filling stage in Hsp90.2‐B‐HapI or Hsp90.2‐B‐HapII RIL lines. (g–i) The kernel length (g), width (h) and thickness (i) of RIL lines with Hsp90.2‐B‐HapI or Hsp90.2‐B‐HapII. n ≥ 10. (j, k) The kernel weight (j, n ≥ 10) and single‐row yields (k, n ≥ 5) of RIL lines with Hsp90.2‐B‐HapI or Hsp90.2‐B‐HapII.
