Bamboos are one of the most beautiful and useful plants on Earth. The genetic background and population structure of bamboos are well known, which helps accelerate the process of artificial domestication of bamboo. Partial sequences of six genes involved in nitrogen use efficiency in 32 different bamboo species were analyzed for occurrence of single nucleotide polymorphisms (SNPs). The nucleotide diversity  θw  and total nucleotide polymorphisms π T  of the sequenced DNA regions was 0.05137 and 0.03332, respectively. Both πnonsyn /πsyn and Ka/Ks values were &lt;1. The nucleotide sequences of these six genes were inferred to be relatively conserved, and the haplotype diversity was relatively high. The results of evolutionary neutrality tests showed that the six genes were in line with neutral evolution, and that the  NRT2.1  and  AMT2.1  gene sequences may have experienced negative selection. An inter-SNP recombination event at the  NRT2.1  gene in the all pooled sample, of all 32 bamboo species was the lowest at 0.0645, whereas the  AMT  gene recombination events were all &gt;0.1. Estimation and analysis of linkage disequilibrium of five genes revealed that with the increase in nucleotide sequence length, the degree of SNP linkage disequilibrium decreased rapidly. We inferred the population genetic structure of 32 bamboo species based on the SNP loci of six genes with frequencies &gt;18%. 32 bamboo species were divided into five categories, which indicated that the combined population of all bamboo species had obvious multivariate characteristics and was heterogeneous; red (Group 1) and green (Group 2) were the main groups.
