Project description:The tradition of animal husbandry in the context of a nomadic lifestyle has been of great significance in the Mongolian society. Both Bactrian camels and horses have been invaluable for the survival and development of human activities in the harsh arid environment of the Mongolian steppe. As camels offer unique and sustainable opportunities for livestock production in marginal agro-ecological zones, we investigated the current genetic diversity of three local Mongolian camel breeds and compared their levels of variation with common native Mongolian camels distributed throughout the country. Based on mitochondrial and nuclear markers, we found levels of genetic diversity in Mongolian populations similar to that reported for Chinese Bactrian camels and for dromedaries. Little differentiation was detected between single breeds, except for a small group originating from the northwestern Mongolian Altai. We found neither high inbreeding levels in the different breeds nor evidence for a population decline. Although the Mongolian camel census size has severely declined over the past 20 years, our analyses suggest that there still exists a stable population with adequate genetic variation for continued sustainable utilization.
Project description:Bactrian camel (Camelus bactrianus) is a large, even-toed ungulate native to the desert areas of Central Asia. Aggregated lymphoid nodules area (ALNA) is known as the special anatomical structure of a Bactrian camel’s stomach that is found in the cardiac glandular area of the abomasum. To advance the exploration of the mucosal immune function of this anatomical feature within the gastrointestinal tract, we quantified the expressed proteins in ALNA using iTRAQ-based proteomic analysis in 6 Bactrian camels. In the experiment, we sampled the reticular mucosal folds region (RMFR) and longitudinal mucosal folds region (LMFR) separately from the ALNA and compared their proteomic quantification results with the samples from the Peyer’s patches (PPs).
