Abstract

The homeotic mutant of Pisum sativum, cochleata, has
stipules replaced by alternative leaf components, abnormal
flowers and reduced fertility. Although the root system dry
weight, root lengths and nodule numbers of cochleata are
similar to those of its wild type, the nodulation phenotype
of the mutant is unique. The nodules typically dichotomously
branch and multiple callus and root structures
emerge from their meristems. These nodule–roots incorporate
a peripheral vascular bundle of the nodule into their
own central vascular cylinder. Both the nodules and roots
of the hybrid structures appear functional. Roles for
COCHLEATA in development are discussed.
