RESUMO
Border Collie dog is one of the famous breed of dog. In the present work we report the complete mitochondrial genome sequence of Border Collie dog for the first time. The total length of the mitogenome was 16,730 bp with the base composition of 31.6% for A, 28.7% for T, 25.5% for C, and 14.2% for G and an A-T (60.3%)-rich feature was detected. It harbored 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and one non-coding control region (D-loop region). The arrangement of all genes was identical to the typical mitochondrial genomes of dogs.

In this study, the complete mitochondrial genome sequence of the Chinese rhesus macaques Macaca mulatta lasiota has been reported for the first time. The total length of the mitogenome was 16,561 bp. It contained the typical structure, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 1 control region. The overall composition of the mitogenome was A (31.7%), G (12.8%), C (30.4%) and T (25.1%). The M. mulatta lasiota mitogenome had 21 tRNA genes folded into a typical clover-leaf secondary structure except for tRNA(Ser).

By using transmission electron microscopy and high performance liquid chromatography, this paper studied the effects of enhanced UV-B radiation on the leaf anthraquinones content and cell ultrastructure of Aloe vera L. After treated with enhanced UV-B radiation 6 hours per day for 20 days, the total anthraquinone content, barbaloin content, and aloe-emondin content in A. vera leaves increased by 31.8%, 11.3%, and 22.0%, respectively, chloroplast envelope membrane was slightly damaged, but the structure of other organelles had no significant change. It was suggested that UV-B radiation could promote the accumulation of anthraquinone in A. vera leaves, but had less effects on the leaf cell ultrastructure.
