Fig. 1From: Insights into the diversification of subclade IVa bHLH transcription factors in FabaceaePhylogenetic tree of subclade IVa bHLH members in fabids. The approximately maximum-likelihood tree was built using FastTree and visualised with MEGA X. The local support values at each node were computed using 1000 resamples and the Shimodaira–Hasegawa test. Details are provided in Additional file 3: Fig. S2Back to article page
