“…In addition to stipule modification, the coch mutation alters various aspects of flower development in all of these lines, as described previously by Yaxley et al (2001). A wild-type pea flower is composed of a keel, two wings, and a standard (Figures 3G and 3I).…”

“…The coch mutation affects both stipule and flower development in pea (Gourlay et al, 2000;Yaxley et al, 2001). The mutation suppresses stipule formation at the first few nodes and changes (B) Phylogeny of the NBCL clade.…”

“…In pea, several floral and leaf homeotic genes have been characterized (Domoney et al, 2006), but COCHLEATA (COCH) remains unidentified. Among the pea mutants, coch represents an interesting case because several organ identities, including nodule identity (Voroshilova et al, 2003;Ferguson and Reid, 2005), are modified by the coch mutation (Marx, 1987;Yaxley et al, 2001). Here, we report the isolation and molecular characterization of the NODULE ROOT (NOOT) and COCH genes from M. truncatula and pea, respectively.…”

“…The coch phenotype (presence of mutant nodules, stipules, and flowers) of the F1 plants demonstrated that they are allelic. The eight coch lines used in our study, including lines JI 2165 and JI 2757 (Yaxley et al, 2001;Ferguson and Reid, 2005), all develop mutant (coch) nodules. We observed early nodule-to-root conversions (see Supplemental Figure 3E online) and the presence of root hair cell types on coch mutant nodules.…”

During their symbiotic interaction with rhizobia, legume plants develop symbiosis-specific organs on their roots, called nodules, that house nitrogen-fixing bacteria. The molecular mechanisms governing the identity and maintenance of these organs are unknown. Using Medicago truncatula nodule root (noot) mutants and pea (Pisum sativum) cochleata (coch) mutants, which are characterized by the abnormal development of roots from the nodule, we identified the NOOT and COCH genes as being necessary for the robust maintenance of nodule identity throughout the nodule developmental program. NOOT and COCH are Arabidopsis thaliana BLADE-ON-PETIOLE orthologs, and we have shown that their functions in leaf and flower development are conserved in M. truncatula and pea. The identification of these two genes defines a clade in the BTB/POZ-ankyrin domain proteins that shares conserved functions in eudicot organ development and suggests that NOOT and COCH were recruited to repress root identity in the legume symbiotic organ.

“…Duplicated cyc-like genes in legumes have more complicated functions than those of the snapdragon. Moreover, some mutants of floral symmetry, such as the peloric mutant in the snapdragon and toadflax, have been reported (Gustafsson, 1979;Luo et al, 1996;Cubas et al, 1999), and there have been some studies on developmental genetics using floral mutants (Yaxley et al, 2001;Benlloch et al, 2003), which have supported the idea that several genes control floral zygomorphy in papilionoid flowers. In addition, Ojeda et al (2009) indicated that epidermal cell shape of petals was different among standard, wing and keel of papilionoid flowers.…”

Information from phylogenetic trees implies zygomorphic flowers have evolved independently from their actinomorphic ancestors several times. There are various types of zygomorphic flowers in the legume subfamilies Caesalpinioideae and Papilionoideae. To understand the relationship between the cell number and size in the petals of zygomorphic flowers, the comparative morphology and anatomy of flower petals were examined in Cercis chinensis and Caesalpinia decapetala var. japonica in Caesalpinioideae, and Lespedeza formosa subsp. velutina and Pueraria lobata in Papilionoideae. Increased petal size is correlated to a higher number and/or size of the cells of the petal in Caesalpinioideae. The characteristics flower morphology of the Papilionoideae has evolved by increased cell numbers, although the cell size was the smallest. Papilionoideae has characteristic papilionoid flowers consisting of five specialised petals. These characteristic morphologies were generated from the complicated changing pattern of cells in petals in the course of legume diversification.
