Two albino mutants (ab1 and ab2) have been derived from long-term shoot proliferation of Bambusa edulis. Based on transmission electronic microscopy data, the chloroplasts of these mutants were abnormal. To study the mutation of gene regulation in the aberrant chloroplasts, we designed 19 pairs of chloroplast-encoded gene primers for genomic and RT-PCR. Only putative NAD(P)H-quinone oxidoreductase chain 4L (ndhE; DQ908943) and ribosomal protein S7 (rps7; DQ908931) were conserved in both the mutant and wild-type plants. The deletions in the chloroplast genome of these two mutants were different: nine genes were deleted in the chloroplast genomic aberration in ab1 and 11 genes in ab2. The chloroplast genes, NAD(P)H-quinone oxidoreductase chain 4 (ndhD; DQ908944), chloroplast 50S ribosomal protein L14 (rpl14; DQ908934), and ATP synthase beta chain (atpB; DQ908948) were abnormal in both mutants. The gene expressions of 18 of these 20 genes were correlated with their DNA copy number. The two exceptions were: ATP synthase CF0 A chain (atpI; DQ908946), whose expression in both mutants was not reduced even though the copy number was reduced; ribosomal protein S19 (rps19; DQ908949), whose expression was reduced or it was not expressed at all even though there was no difference in genomic copy number between the wild-type and mutant plants. The genomic PCR results showed that chloroplast genome aberrations do occur in multiple shoot proliferation, and this phenomenon may be involved in the generation of albino mutants.
