Heatmap showing log₂ fold-change expression of 70 AhypNAC genes across eight tissues and five stress conditions in Amaranthus hypochondriacus. (A) Genes are grouped into eight clusters (I–VIII) based on expression similarity. Red and blue indicate high and low expression, respectively. Top colour bar marks sample type: green (tissue) and yellow (stress). (B) qRT-PCR validation of AhypNAC03, AhypNAC70, AhypNAC23 and AhypNAC24 under different water stress.
