Sectors of liguleless-1 tissue interrupt an inductive signal during maize leaf development.

The Plant cell - 1 Aug 1991

Becraft P W, Freeling M

Abstract excerpt

The ligule and auricles separate the blade and sheath of normal maize leaves and are absent in liguleless-1 (lg1) mutant leaves. We induced chromosome breakage using X-rays to create plants genetically mosaic for lg1. In genetically mosaic leaves, when an lg1 mutant sector interrupts the normal ligule, the ligule is often displaced basipetally on the marginal side of the sector. Therefore, lg1 mutant sectors not...
