(14) 14), we conclude that the information carried by the Lg1+ gene product acts earlier in development than formation of the ligule proper.
(15) Mutants homozygous for the recessive liguleless-1 (lg1) allele exhibit loss of normal ligule and auricle.
(16) The ligule, a fringe normally found at the junction of leaf blade and sheath, is often displaced and perpendicular to its normal position.
(17) 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.
(18) The maize leaf is composed of a blade and a sheath, which are separated at the ligular region by a ligule and an auricle.
(19) The recessive lg1 mutation prevents formation of ligules and auricles during leaf development.
