Interaction between COCHLEATA and UNIFOLIATA genes enables normal flower morphogenesis in the garden pea, Pisum sativum

Abstract

The simple stipules, leaflet and tendril bearing imparipinnately compound leaf blades and zygomorphic flowers, produced on stems of the diploid (2n = 14; ≥ 5000 Mbp nuclear genome) papilionoid Fabaceae plant Pisum sativum, are serving as unique and highly informative models for the dis- section of plant developmental programmes. The growing information has revealed that the processes of stipule, leaf and flower morphogeneses are genetically interconnected in P. sativum (Hofer et al. 1997; Yaxley et al. 2001; Wang et al.2008; Kumar et al. 2009).
