Extended Data Fig. 4 | Expansion of key genes regulating the carpel
development by the Nymphaealean WGD. a, The reported pathway and genes
that regulate carpel development. The red-labelled gene has two copies in
N. colorata. The asterisk indicates that there is collinear support and is retained
by the nymphaealean-specific WGD. b, Phylogenetic tree of AG genes, which
specify f loral meristem to determine the carpel and stamen identity.
The star indicates the WGD specific to the water lily, as detected in this study.
The duplicated AG genes in N. colorata are highlighted in red. c, NcAG gene
duplicates, NcAGa and NcAGb, are the result of the nymphaealean-specific
WGD.
