Plants develop through at least three distinct phases after germination: a juvenile
vegetative phase; an adult vegetative phase; and a reproductive phase. Therefore, there
exist two main ontogenetic transitions, the juvenile-adult vegetative transition or
vegetative phase change, and the adult vegetative-reproductive phase transition or
reproductive phase change. The genetic and physiological control of the transition to
flowering has been studied intensively over the past four decades but the other major
transition has received much less attention. This study investigates the genetic and
physiological regulation of vegetative phase change in the garden pea (Pisum sativum L)
using a novel heterochronic mutant, accelerated phase change (apc), which expresses a
consistent difference in the rate of vegetative phase change when compared to the wild
type plants. Genetic analyses, using morphological and enzyme markers, revealed that the
apc locus is on linkage group 131 (between a and aat-p genes) of the garden pea.
