RESUMO
Burkholderia pyrrocinia CH-67 was isolated from forest soil as a biocontrol agent to be utilized in agriculture. Here, we report the 8.05-Mb draft genome sequence of this bacterium. Its genome contains genes involved in biosynthesis of secondary metabolites and plant growth promotion, which may contribute to probiotic effects on plants.

Abstract The complete nucleotide sequences of the mitochondrial genome from the whiter-spotted flower chafer, Protaetia brevitarsis (Coleoptera: Scarabaeidae), was determined. The 20,319-bp long circular genome is the longest among completely sequenced Coleoptera. As is typical in animals, the P. brevitarsis genome consisted of two ribosomal RNAs, 22 transfer RNAs, 13 protein-coding genes and one A + T-rich region. Although the size of the coding genes was typical, the non-coding A + T-rich region was 5654 bp, which is the longest in insects. The extraordinary length of this region was composed of 28,117-bp tandem repeats and 782-bp tandem repeats. These repeat sequences were encompassed by three non-repeat sequences constituting 1804 bp.

In this study, the 17,694-bp long complete mitochondrial genome (mitogenome) of the dwarf honeybee, Apis florea (Hymenoptera: Apidae), was described, and a noteworthy triplicated tRNA(ser)(AGN) region and an extraordinary long A+T-rich region with repeat regions were identified. The gene arrangement of A. florea mitogenome was identical to that of Apis mellifera, but it contained three tRNA(Ser)(AGN), each of which was preceded by a 44-bp-long repeat unit and followed by a 64-bp-long repeat unit plus one complete first repeat adjacent to tRNA(Met). A total of 1610-bp long two repeat regions in 1987-bp long A+T-rich region were composed of nearly identical 141-219-bp long 5 tandem repeats and 50-52-bp long 12 tandem repeats that were encompassed by three non-repeat sequences. One potential explanation for this repeat sequence is slipped-strand mispairing and unequal crossing-over events during DNA replication.
