To reveal the whole genome differences of moso bamboo variations on culm shape, Phyllostachys edulis f. obliquinoda, Phyllostachys edulis f. heterocycla, Phyllostachys pubescens f. curviculmi, Phyllostachys edulis f. tubaeformis were re-sequenced by whole genome re-sequencing, to detect and annotate the single nucleotide polymorphism (SNP), insertion-deletion (InDel) and structure variation (SV). The mutant genes were compared with the functional databases of GO, COG, KEGG, of which 7 477, 7 584, 7 221 and 7 583 mutant genes were annotated respectively. GO annotation classification included 56 functional groups of three functional classification systems: cellular component, molecular function and biological processes. COG classification showed that 369 genes involved in replication, recombination and repair, 327 genes involved in signal transduction mechanism, and 253 genes involved in transcription. The metabolic pathways of flavonoids, carotenoids and other substances involved in the mutant genes were analyzed by KEGG database. In-depth study of the regulatory pathways can provide a theoretical basis for further exploration of the rich polymorphism and genetic variation of moso bamboo, and the development of molecular markers for some significant characters.
