Abstract
Variation in gene expression profile with aging of Pinus radiataD. Don
Highlights
Phase change in higher plants, from juvenile to mature, affects the reproductive competence, morphology and growth rate, as well as the regenerative potential of tissue explants

The previous results are consistent with the higher expression level in RUBISCO activase in the younger ortets (1 and 3 year old), which in turn agree with different studies, indicating that photosynthesis is reduced with increasing age of shrubs and trees [7] and higher in the younger ones
Summary
Phase change in higher plants, from juvenile to mature, affects the reproductive competence, morphology and growth rate, as well as the regenerative potential of tissue explants. This work has been performed to gain deeper insight into the genetic mechanisms that regulates the loss of morphogenetic capacity with the aging process in P. radiata.
