RESUMEN
Handeliodendron bodinieri (Sapindaceae) is an endangered monotypic species endemic to the karst forests in southwest China whose populations are now fragmented and the total number of individuals evidently decreased. In this research, we characterized the chloroplast (cp) genome of H. bodinieri using genome skimming. The whole cp genome was 155,291 bp long and comprised 137 genes, including 8 unique rRNAs, 40 tRNAs, and 89 protein-coding genes. The overall guanine-cytosine content of H. bodinieri cp genome was 37.8%. The phylogenetic analysis suggested that H. bodinieri is closely related to the genus Mangifera. This study will be useful for future studies on conservation genetics of this economically important endemic plant.
RESUMEN
The aim of current study was to evaluate the prospects of adjuvants against DNA vaccination (pES/2SS) encoding somatostatin (SS) and hepatitis B surface antigen fusion gene. A total of 60 female Hu lambs were divided into 6 groups and vaccinated in the context of various adjuvants (and controls): pE-CpG, Escherichia coli DH5alpha DNA, crude liposomes or GM-CSF in combination with the pES/2SS plasmid. Controls included pES/2SS only vaccinated and physiological saline groups. The antibody against SS level in the E. coli DH5alpha DNA group was significantly increased compared to that in the pES/2SS vaccine alone. Vaccination with pES/2SS/pE-CpG or pES/2SS/E. coli DH5alpha resulted in elevated weight gains that were 33.0 and 31.6% higher, respectively, than in saline group and pES/2SS only vaccinated controls. The concentrations of GH and IGF-I in the DNA vaccine groups were remarkably higher than those in the saline group, and those with positive antibody higher than negative antibody. These results suggested that different adjuvant/pES/2SS combinations can enhance the immune effect and had significant positive effects on growth.
