ML analysis of the LFY transcription factor family a Summary tree including sequences from algae, bryophytes and tracheophytes with Boostrap values (BS) as numbers on top of branches for major clades. b Detail of lycophyte and fern LFY clades. Yellow stars indicate large scale (major) duplication events. Number on each node indicate the BS. Black arrowheads point to sequences isolated in this study. The colors correspond to the conventions on the bottom left. Scale: 0.3
