Extended Data Fig. 6: Analysis of gene copy number and functional variation for key embryogenesis-related genes in Kalanchoe.

a, BBM maintains a single copy in all three species; no obvious variations in protein length or key domains were found. b, WUS maintains a single copy in K. daigremontiana and K. marnieriana, with 2 copies in K. fedtschenkoi; no obvious variations in protein length or key domains were found. c, AGL15 and its paralog AGL18 maintain a single copy in all three species; no obvious variations in protein length or key domains were found. d, ABI3 has 2 copies in all three species; no obvious variations in protein length or key domains were found. e, WOX2 has 2 copies in K. daigremontiana, and a single copy in K. fedtschenkoi and K. marnieriana; and WOX4 maintains a single copy in all three species; no obvious variations in protein length or key domains were found. f, LEC1 maintains a single copy in K. daigremontiana and K. marnieriana, with 2 copies in K. fedtschenkoi; however, LEC1 protein is truncated, and key domains are disrupted in K. daigremontiana and K. fedtschenkoi. L1L maintains a single copy in all three species, with no obvious variations in protein length or key domains. g, SERK1 and SERK2 maintain a single copy in all three species; no obvious variations in protein length or key domains were found. h, FUS3 has 3 copies in all three species; one copy encodes a novel protein domain, suggesting potential neofunctionalization. i, STM has 2 copies in all three species; no obvious variations in protein length or key domains were found. j, AHL15 has 2 copies in all three species; no obvious variations in protein length or key domains were found.
