Summary: Mono- and sesquiterpenes are important volatile organic compounds in table grape and wine flavour and aroma, and their biosynthesis and genetic variation have been extensively studied. The HMG-CoA reductase and DXS enzymes are the key regulators in the formation of terpene precursors. The terpene synthase enzymes show functional plasticity, leading to a wide range of terpene product accumulation. These compounds not only affect grape quality, but also play various roles in the grapevine's interaction with the environment. The genetic variation in terpene synthase genes could potentially be utilized for breeding and biotechnology applications.

Summary: Heart failure is a growing epidemic with a high mortality rate. Metabolic therapy, particularly the manipulation of fatty acid and glucose oxidation, has been suggested as a new therapeutic strategy. Recent studies have shown that the non-genomic progesterone receptor Pgrmc1 is involved in cardiac energy metabolism and its loss can protect the heart from energy starvation-induced damage. Pgrmc1 may act as a regulator of cardiac metabolism, switching the utilization of glucose and fatty acids according to nutrient availability.

Summary: Despite previous studies suggesting a negative relationship between age and telomere length, recent research has challenged the universality of this pattern, especially in ectothermic animals. This study examined the age-related changes in telomere length in a long-lived amphibian living in a stable thermal environment. The results showed a positive relationship between telomere length and age, independent of sex and body size. The findings suggest a plateau in telomere length at 25 years of age.

Summary: The aerobic metabolism of aquatic ectotherms is sensitive to fluctuating climates, with mitochondrial respiratory capacities and efficiency being key factors affecting performance. The combined effects of temperature and oxygen availability on mitochondrial metabolism play a critical role in shaping the responses of these organisms to environmental changes. Predictions on decline in performance due to climate change may not be accurate if only respiratory capacity is considered, as ATP production efficiency also plays a significant role.

Summary: The study challenges the assumption that mitochondrial ROS production is proportional to oxygen consumption at the whole organismal level. The model developed in the study suggests that differences in ROS production per unit oxygen consumed between respiration states do not disrupt the proportionality between whole animal ROS production and oxygen consumption. Additionally, the model shows that mitochondrial uncoupling generally enhances this proportionality.

Summary: The acclimatization of certain ectothermic vertebrates to winter conditions involves reduced energy consumption, achieved through decreased movement activity, depression of cellular functions, or switching to anaerobic energy production. This study on crucian carp showed that winter-acclimatized fish exhibited lower metabolic rates and a shift to anaerobic energy production during anoxia. Winter dormancy in crucian carp is achieved through active reduction of energy consumption, a slowed metabolic rate, and a direct response to oxygen absence.

Summary: According to life-history theory, there might be different immunological strategies between reproductive and non-reproductive periods due to limited resources. Our study on two sympatric marine fish species, rockfish and sandperch, found that reproductive individuals showed lower immune function, but higher levels of natural antibodies in rockfish females, compared to their non-reproductive counterparts. On the other hand, reproductively active sandperch males showed lower levels of natural antibodies and higher neutrophil to lymphocyte ratio and spleen index compared to non-reproductive males. The study highlights the species-specific patterns of immunity and the potential influence of resource limitation and abiotic factors on immune trade-offs in fish.
