Is the genus Cissus (Vitaceae) monophyletic? Evidence from plastid and nuclear ribosomal DNA
The trnL (UAA) intron and ITS1 region were sequenced to investigate relationships among the five genera of Vitaceae present in Australia relative to Vitis. Congruent results were obtained between separate and combined data sets, with all major clades being shared among trees. All bootstrap consensus...
