maize mutant phenotypes

This is an old revision of the document!

Hairy sheath frayed Hairy leaf sheath and a few hairy breaks scattered along leaf margin; Homozygotes more extreme with hairy leaf margin breaks being the site of gross morphological tissue protuberances.

Hairy sheath frayed Homozygous Hsf1-N1595 mutant plant showing paired ligule-like structures on leaf blade apparently resulting from breakdown of integrity of the leaf margin.

Hairy sheath frayed Hairy sheath, frayed: Homozygous Hsf*-N2559 mutant plant showing tiny hairy breaks in leaf margin and larger prominent tissue distortions also on the leaf margins.
