Neomicrocalamus and Temochloa are closely related to bamboo genera.
However, when considered with newly discovered and morphologically similar
material from China and Vietnam, the phylogenetic relationship among these
three groups was ambiguous in the analyses based on DNA regions. Here, as a
means of investigating the relationships among the three bamboo groups and
exploring potential sources of genomic conflicts, we present a phylogenomic
examination based on the whole plastome, single-nucleotide polymorphism
(SNP), and single-copy nuclear (SCN) gene datasets. Three different phylogenetic
hypotheses were found. The inconsistency is attributed to the combination of
incomplete lineage sorting and introgression. The origin of newly discovered
bamboos is from introgressive hybridization between Temochloa liliana (which
contributed 80.7% of the genome) and Neomicrocalamus prainii (19.3%),
indicating that the newly discovered bamboos are closer to T. liliana in
genetics. The more similar morphology and closer distribution elevation also
imply a closer relationship between Temochloa and newly discovered bamboos.
