Data on the draft genome sequence of Caryocar brasiliense Camb. (Caryocaraceae): An important genetic resource from Brazilian savannas.

ABSTRACT: Caryocar brasiliense (Caryocaraceae) is a Neotropical tree species widely distributed in Brazilian savannas. This species is very popular in central Brazil mainly due to the use of its fruits in the local cuisine and their anti-inflammatory proprieties, and indeed it is one of the candidates, among Brazilian native plants, for fast track incorporation into cropping systems. Considering the importance of Caryocar brasiliense, little is known about its genetics and genomics, and determination of a reference genome sequence could improve the understanding of its evolution, as well as the development of tools for domestication. Here, we provide the first draft genome of C. brasiliense, the raw sequencing data and some multiplex sets of high quality microsatellite primers. Data on the genome project can be obtained from the BioProject at NCBI (https://www.ncbi.nlm.nih.gov/bioproject/?term=caryocar).

Project description:The present study was conducted to determine the possible antioxidant protection of pequi oil (PO) against cyclic heat stress in broiler chickens and to highlight the application of PO as a promising additive in broiler feed. A total of 400 one-day-old male broiler chicks (Cobb 500) were randomly assigned to 2 × 5 factorially arranged treatments: two temperature-controlled rooms (thermoneutral-TN or heat stress-HS for 8 h/day) and five dietary PO levels (0, 1.5, 3.0, 4.5, or 6.0 g/kg diet) for 42 days. Each treatment consisted of eight replicates of five birds. The results showed that HS increased glucose (p = 0.006), triglycerides (p < 0.001), and HDL (p = 0.042) at 21 days and reduced (p = 0.005) serum total cholesterol at 42 days. The results also showed that HS increased the contents of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). In contrast, PO linearly decreased AST (p = 0.048) and ALT (p = 0.020) at 21 and 42 days, respectively. The heterophil-to-lymphocyte ratio in the birds under HS was higher than in those in the TN environment (p = 0.046). Heat stress decreased (p = 0.032) the relative weight of their livers at 21 days. The superoxide dismutase activity increased (p = 0.010) in the HS treatments in comparison to the TN treatments, while the glutathione peroxidase activity in the liver decreased (p < 0.001) at 42 days; however, the activity of catalase had no significant effects. Meanwhile, increasing the dietary PO levels linearly decreased plasma malondialdehyde (p < 0.001) in the birds in the HS environment. In addition, PO reduced (p = 0.027) the expression of Hsp 70 in the liver by 92% when compared to the TN treatment without PO, mainly at the 6.0 g/kg diet level. The expression of Nrf2 was upregulated by 37% (p = 0.049) in response to PO with the 6.0 g/kg diet compared to the HS treatment without PO. In conclusion, PO supplementation alleviated the adverse effects of HS on broilers due to its antioxidant action and modulation of the genes related to oxidative stress, providing insights into its application as a potential feed additive in broiler production.
