Fig. 1From: Evolution patterns of NBS genes in the genus Dendrobium and NBS-LRR gene expression in D. officinale by salicylic acid treatmentThe ML phylogenetic tree of CNL genes. CNL genes are mainly divided into three branches: a, b and c. Different colors represent different species, including D. officinale, D. nobile, D. chrysotoxum, V. planifolia, A. shenzhenica, P. equestris and A. thalianaBack to article page
