Est-7, a set of genes controlling green tissue esterases in wheat and related species.
Analysis using isoelectric focusing of "Chinese Spring" wheat genetic stocks revealed a set of coleoptile and leaf esterase loci, designated Est-7, on the long arms of the group 2 chromosomes. A survey of 38 other hexaploid genotypes revealed onyl a single variant, at Est-D7. Homoeoloci were found on chromosome (arm) 2HL of Hordeum vulgare, 2RL of Secale cereale, 2R (m)α of S. montanum, 2U of Aegilops umbellulata, 2E of Agropyron elongation and 2V of Dasypyrum villosa.
