Author contributions
H.P.X. and Q.F.W. initiated the study of Cissus rotundifoliagenome sequencing project. H.P.X, Y.W., Q.Y.L and T.W. are joint first authors. D.K.G and Z.F.Z confirmed the genome size and chromosome numbers with help of B.L. D.K.G and H.M.Z. isolated DNA. Y.W. and Q.Y.L. carried out the genome assembly, annotation and transcriptome analysis with the help of J.S.Z., Y.W. carried out the phylogenomic analyses with the help of Y.D.Z., B.L., T.W. and Z.D.C., Y.J.H., Y.S.L. and C.X. detected the diel acid fluctuation in the leaves of C. rotundifolia . Y.S.L., R.J.L, Z.M.L and Q.Y.L. identified the CAM pathway related genes. Y.J.H and Q.Y.L isolated the total RNAs and performed the expression pattern analysis of CAM pathway related genes with the help of H.S.J., H.P.X., Y.W., Q.Y.L., J.W. and Q.F.W. wrote the initial manuscript. J.W., J.N.W., Z.D.C., Z.C.L., L.M.L., G.W.H., R.J.L., R.A. and R.W.G. contributed the discussion of project at different stages. All authors revised and contributed to the final version of the text.
