Abstract

Pea (Pisum sativum L.) is a classic model for compound leaf development. Pea leaves typically consist of a proximal series of paired lateral leaflets substituted distally by filiform tendrils, and the number of lateral organ pairs increases with ontogeny. This gradient has been proposed as an expression of heteroblasty, but no clear links with known leaf-development pathways have been demonstrated…
