Mitochondrial gene expression in the liver and muscle of high and low feed efficiency Japanese quail layers subjected to different environmental temperatures

D. M. Voltolini, Del Vesco, A. P., Gasparino, E., Guimarães, S. E. F., Neto, A. R. Oliveira, Batista, E., and Ton, A. P. S., Mitochondrial gene expression in the liver and muscle of high and low feed efficiency Japanese quail layers subjected to different environmental temperatures, vol. 13, pp. 4940-4948, 2014.

We evaluated the adenine nucleotide translocator (ANT) and cytochrome oxidase subunit III (COX III) mRNA expressions in the muscle and liver of Japanese quails presenting high and low feed efficiency (FE), and subjected them to three different environmental temperatures: comfort, heat stress (38°C), and cold stress (10°C). ANT mRNA expression was lower in the liver of heat-stressed animals. In the muscle, higher ANT and COX III mRNA expressions were observed in high-FE and cold-stressed animals.

Relationships among lipid peroxidation, SOD enzyme activity, and SOD gene expression profile in Lycopersicum esculentum L. exposed to cold stress

S. S. Aydin, Büyük, İ., and Aras, S., Relationships among lipid peroxidation, SOD enzyme activity, and SOD gene expression profile in Lycopersicum esculentum L. exposed to cold stress, vol. 12, pp. 3220-3229, 2013.

The current study was designed to evaluate lipid peroxidation (via malondialdehyde) levels, the superoxide dismutase (SOD) gene expression profile, and SOD enzyme activity in tomato plants (Lycopersicum esculentum L.) subjected to different time periods of cold stress (control, 2, 4, 6, 8, and 10 days). Results revealed that maximum lipid peroxidation occurred in plants exposed to cold stress for 10 days, and SOD enzyme activity gradually increased with increasing exposure to cold stress.
