Species within the Ranunculales bear flowers of formidable variation; for example, one can find novel floral organs and loss of floral organs, zygomorphic and radially symmetric flowers, and variation in floral organ...

Zygomorphy evolved from disymmetry in Fumarioideae
Floral bilateral symmetry (zygomorphy) has evolved at least 70 times during the history of angiosperms, whilst radial symmetry (actinomorphy) is the ancestral and most common state for angiosperms as a whole. Sauquet et...
Expression of floral MADS-box genes in Sinofranchetia
The second-whorl floral organs of Sinofranchetia chinensis (Lardizabalaceae) are nectar leaves. Hu et al. study the expression patterns of floral MADS-box genes in S. chinensis and find that SIchAP3-3 is significantly...
Heterodichogamy avoids inbreeding in Kingdonia
Heterodichogamy, an unusual kind of reproductive heteromorphy, is hitherto unreported in Ranunculales and is known from only one other genus in the basal eudicots. Wang et al. study flowers of Kingdonia uniflora, an...
Virus-induced gene silencing and evo-devo studies in Cysticapnos
Gene silencing studies are increasingly being used to unravel the role of developmental genes. Hidalgo et al. report the establishment of virus-induced gene silencing (VIGS) in Cysticapnos vesicaria, a member of the...
