Epigenetic 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 کاملEpigenetic Regulation of Vegetative Phase Change in Arabidopsis.
Vegetative phase change in flowering plants is regulated by a decrease in the level of miR156. The molecular mechanism of this temporally regulated decrease in miR156 expression is still unknown. Most of the miR156 in Arabidopsis thaliana shoots is produced by MIR156A and MIR156C. We found that the downregulation of these genes during vegetative phase change is associated with an increase in th...
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 کاملMiRNA Control of Vegetative Phase Change in Trees
After germination, plants enter juvenile vegetative phase and then transition to an adult vegetative phase before producing reproductive structures. The character and timing of the juvenile-to-adult transition vary widely between species. In annual plants, this transition occurs soon after germination and usually involves relatively minor morphological changes, whereas in trees and other perenn...
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...
