Extended Data Fig. 5 | Expansion of key genes regulating the development of
the stamen by Nymphaealean WGD. a, The reported pathway and genes that
regulate the stamen 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 CORONATINE
INSENSITIVE 1 (COI1), which recruits regulators of pollen development for
modification by ubiquitination, needed in the JA response and regulating
pollen fertility. c, NcCOI1 gene duplicates have evolved through the WGD in
Nymphaeales. The star indicates the nymphaealean-specific WGD.
