Gibberellins promote vegetative phase change and reproductive maturity in maize.
Postembryonic shoot development in maize (Zea mays L.) is divided into a juvenile vegetative phase, an adult vegetative phase, and a reproductive phase that differ in the expression of many morphological traits. A reduction in the endogenous levels of bioactive gibberellins (GAs) conditioned by any one of the dwarf1, dwarf3, dwarf5, or anther ear1 mutations in maize delays the transition from j...
متن کاملEpigenetic reprogramming during vegetative phase change in maize.
An important step during plant development is the transition from juvenile to adult growth. It is only after this transition that plants are reproductively competent. Given the great danger that transposon activity represents to the germ line, this may also be an important period during development with respect to transposon regulation and silencing. We demonstrate that a change in expression o...
متن کاملMicroarray analysis of vegetative phase change in maize.
Vegetative phase change is the developmental transition from the juvenile phase to the adult phase in which a plant becomes competent for sexual reproduction. The gain of ability to flower is often accompanied by changes in patterns of differentiation in newly forming vegetative organs. In maize, juvenile leaves differ from adult leaves in morphology, anatomy and cell wall composition. Whereas ...
متن کاملDynamics of gene expression during vegetative phase change in maize
ii ACKNOWLEDGEMENTS There are many people who assisted me in ways large and small in the performance of this research and to whom I am indebted. Without their catalytic, nearly enzymatic function this would not have been possible. Dr. Erin Irish has been reliably helpful and patient in our collaboration, which is to say, she was an excellent mentor. The members of my committee are also owed a g...
متن کاملThe early phase change gene in maize.
Recessive mutations of the early phase change (epc) gene in maize affect several aspects of plant development. These mutations were identified initially because of their striking effect on vegetative phase change. In certain genetic backgrounds, epc mutations reduce the duration of the juvenile vegetative phase of development and cause early flowering, but they have little or no effect on the n...
