ABSTRACT Vegetative development in maize is divided into a juvenile phase and an adult that differ the expression of large number morphological, anatomical, biochemical traits. Recessive mutations Glossy15 cause premature switch some these phase-specific Mutant plants cease producing traits (e.g. epicuticular wax) begin to produce epidermal hairs) significantly earlier than their wild-type siblings. In glossy15-1 this generally occurs at leaf 2 or 3 rather normal position 6 7. An analysis effect glossy15 on variety vegetative reproductive revealed only affect character epidermis. They have no overall morphology plant, its development. This phenotype opposite gain-of-function Teopod1, Teopod2 Teopod3, all which prolong Double mutants between Teopod1 indicate required for but not other aspects Teopod phenotype. We conclude initiates maintains suppresses traits, it acts downstream genes.
