The extended auricle1 (eta1) gene is essential for the genetic network controlling postinitiation maize leaf development.

Genetics - 1 Nov 2003

Osmont Karen S, Jesaitis Lynne A, Freeling Michael

Abstract excerpt

The maize leaf is composed of distinct regions with clear morphological boundaries. The ligule and auricle mark the boundary between distal blade and proximal sheath and are amenable to genetic study due to the array of mutants that affect their formation without severely affecting viability. Herein, we describe the novel maize gene extended auricle1 (eta1), which is essential for proper formation of the...
