Insights into the Response in Digestive Gland of Mytilus coruscus under Heat Stress Using TMT-Based Proteomics

Ocean warming can cause injury and death in mussels is believed to be one of the main reasons for extensive die-offs mussel populations worldwide. However, biological processes by which respond heat stress are still unclear. In this study, we conducted an analysis enzyme activity TMT-labelled based proteomic digestive gland tissue Mytilus coruscus after exposure high temperatures. Our results showed that activities superoxide dismutase, acid phosphatase, lactate dehydrogenase, cellular content lysozyme were significantly changed response stress. Furthermore, many differentially expressed proteins involved nutrient digestion absorption, p53, MAPK, apoptosis, energy metabolism activated post-heat These suggest M. through antioxidant system, immune anaerobic respiration. Additionally, may use fat, leucine, isoleucine meet requirements under temperature via TCA cycle pathway. findings provide a useful reference further exploration mechanism marine mollusks.

Parental exposure to ocean acidification impacts gamete production and physiology but not offspring performance in Nematostella vectensis

Biology Open, Journal Year: 2023, Volume and Issue: 12(3)

Ocean acidification (OA) resulting from anthropogenic CO2 emissions is impairing the reproduction of marine organisms. While parental exposure to OA can protect offspring via carryover effects, this phenomenon poorly understood in many invertebrate taxa. Here, we examined how acidified (pH 7.40) versus ambient 7.72) seawater influenced and performance across six gametogenic cycles (13 weeks) estuarine sea anemone Nematostella vectensis. Females exhibited reproductive plasticity under acidic conditions, releasing significantly fewer but larger eggs compared females after 4 weeks exposure, two four following spawning despite recovering fecundity, indicating long-term acclimatization greater investment eggs. Males showed no changes fecundity conditions produced a percentage sperm with high mitochondrial membrane potential (MMP; proxy for elevated motility), which corresponded higher fertilization rates relative males. Finally, did not influence development rates, respiration or heat tolerance. Overall, study demonstrates that impacts gamete production physiology N. vectensis, suggesting increased individual gametes may promote fitness.

Ocean acidification alters sperm responses to egg-derived chemicals in a broadcast spawning mussel

Biology Letters, Journal Year: 2022, Volume and Issue: 18(4)

Published: April 1, 2022

The continued emissions of anthropogenic carbon dioxide are causing progressive ocean acidification (OA). While deleterious effects OA on biological systems well documented in the growth calcifying organisms, lesser studied impacts include potential gamete interactions that determine fertilization, which likely to influence many marine species spawn gametes externally. Here, we explore signalling mechanisms enable sperm track egg-derived chemicals (sperm chemotaxis). We focus mussel
