Complete mitochondrial genome sequence of Pseudecheneis Sulcata in the Yarlung Zangbo River, Tibet.

ABSTRACT: Pseudecheneis sulcata belongs to Sisoridae, Pseudecheneis, which is mainly distributed in India and Tibet of China, and is located in the Motuo and Chayu in the lower reaches of the Yarlung Zangbo River in Tibet. In the present study, we obtained the complete mitochondrial genome sequence of Pseudecheneis sulcata, which was 16,535 bp in length. This genome consisted of 13 protein-coding genes, 22 tRNAgenes, 2 rRNA genes and a non-coding control region. The protein-coding genes have three start codons (GTG, ATG, and CTA) and four stop codons, including three complete stop codons and one incomplete stop codon. To verify the accuracy and utility of newly determined mitogenome sequences by constructing a species phylogenetic relationship tree of species, we expect to use the full mitochondrial gene sequence to interpret related evolutionary events.

Project description:BackgroundDietary intake and nutritional assessing data from a representative sample of adult population living in an agricultural zone on Tibet Plateau are still lacking nowadays. This study aimed to assess the daily dietary intakes and respective food sources in 552 local residents (≥ 18 years old, 277 men and 275 women) living in 14 agricultural counties along the Yarlung Zangbo River on Tibet Plateau.MethodsFood consumption data were collected using a validated cultural-specific food frequency questionnaire that contained all local Tibetan foods and analyzed with three fixed factors: gender, age, and region. Nutrient intakes were calculated using Chinese food composition tables. Nutritional gaps and the percentages of participants who had inadequate and excessive nutrient intakes were calculated by estimated average requirement (EAR) cut-point methods.ResultsCompared with the dietary reference intakes, 68.4% of nutrient intakes were inadequate. Fiber, Ca, I, Zn, Se, and vitamin (Va, Vc, and folic acid) intakes appeared to be particularly deficient. The dietary energy intake was 7838.8 ± 537.1 KJ/d, with 78 and 84% of EAR values for men and women, respectively. The dietary intakes of most nutrients were below the estimated energy requirement/EAR or adequate intake values, while more than 70% of the participants had excessive intake of carbohydrate, especially the elderly (aged ≥ 51 years). The nutritional gap of Cu was more than 300%. Almost 100% of the participants was vulnerable to fiber, Se, and Va shortfalls due to the deficiency in sole food sources. The top five food sources of Se intake were highland barley (34.2%), meat (13%), rice (12.4%), eggs (12.2%), and cultural-specific beverages (7.8%). Eggs (42.1%), tubers (62.2%), vegetables (66.4%), and highland barley (49.7%) were the first contributors of Va, Ve, Vc, and folic acid, respectively.ConclusionThe dietary intake of a large sample of Tibetan adult population living in agricultural counties of Tibetan Autonomous Region is alarmingly insufficient. Gender inequality is common, and regional difference is widespread due to rapid urbanization. Young Tibetan adults aged 18-30 years are particularly vulnerable to micronutrient shortfalls and currently facing the risk of nutrition-insecurity-related dietary inadequacy. The respondents who belong to the elderly category (≥51 years of age) are facing the risk of "double burden of malnutrition" characterized by the coexistence of undernutrition, including micronutrient deficiencies and overweight or obesity.
