Summary Most rice varieties are able to grow in red high‐Fe soil, but the underlying mechanism remains elusive. Through forward genetic screening, we identified a red soil‐sensitive‐1 (rss1) mutant that exhibited severely retarded growth when grown in red soil but showed no evident phenotype in cinn...
