Fig. 1 in Stilbenes: Source plants, chemistry, biosynthesis, pharmacology, application and problems related to their clinical Application-A comprehensive review

Fig. 1. Phylogenetic tree of known stilbene-producing plants: Each family was marked with a different color in the figure. The circle-marked species are capable of producing stilbenes. Kappaphycus striatum (JN897024.1) and Silvetia siliquosa (JF718409.1) are included as out-groups. The phylogenetic tree was constructed using the ITS2 (ribosomal internal transcribed spacer 2) genus sequence. ITS2 sequences were obtained from NCBI (National Center for Biotechnology Information) (https://www.ncbi.nlm.nih.gov/). Some unannotated sequences were identified and delimited based on Hidden Markov models (HMMs), which was performed through the online website-ITS2 Database (http://its2.bioapps.biozentrum.uni-wuerzburg.de/). The MUSCLE program in MEGA6.0 software was used to perform multiple sequence alignments, and the neighbor-joining (NJ) method was used to construct phylogenetic trees with 1000 bootstrap replicates. The kimura-2- parameter substitution model was also employed, and the confidence interval was 95%. The evolutionary tree is visualized and beautified by the online software iTOL (https://itol.embl.de/).
