KAUST Discovery Professor Aranda's team has been researching coral adaptation to temperature and ocean acidification. The research is focused on the transgenerational aspect of this adaptation using controlled environments. The research has been ongoing for the past two years. Why it matters: Understanding the epigenetic mechanisms of climate resilience in corals is crucial for conservation efforts in the Red Sea and beyond.
A KAUST-led research team has observed intergenerational epigenetic inheritance in corals, demonstrating that corals pass patterns of DNA to their offspring. The research, published in Nature Climate Change, shows that corals can adapt to environmental changes and pass those traits on through DNA methylation patterns. This is the first time this process has been observed in animals, previously only seen in plants. Why it matters: This finding could enable biologists to train corals in nurseries to produce offspring better equipped to survive changing marine environments, aiding coral reef restoration efforts.
KAUST's Environmental Epigenetics Program (KEEP), led by Prof. Valerio Orlando, focuses on understanding how cells acquire and maintain memory, particularly in response to environmental factors. The research investigates the role of non-coding RNA and chromosomal components in regulating gene expression beyond the DNA sequence. Epigenetics explains how the same genome can be interpreted differently, allowing cells and organs to adapt to changing conditions. Why it matters: This research could provide insights into how environmental factors impact gene expression and cell function, potentially leading to advances in understanding and treating diseases.
KAUST researchers are studying coral reefs in the Northern Red Sea, which exhibit unusual heat tolerance, surviving temperatures 5°C above the mean summer maximum. This resilience makes them a potential refuge for coral, offering a "climate change insurance" for the next 100 years. Researchers aim to understand the mechanisms behind this thermotolerance to aid coral conservation efforts globally. Why it matters: Understanding and preserving these unique coral reefs could provide crucial insights and strategies for protecting coral ecosystems worldwide in the face of rising ocean temperatures.
KAUST researchers are studying corals in the Red Sea and Arabian Gulf that are more tolerant of high temperatures. They are mating corals from different parts of the world, assuming that the offspring will be more heat-resistant. Using a commercial coral spawning system, the researchers can time coral spawning to cross colonies that would not naturally cross. Why it matters: This research aims to identify genes responsible for temperature resilience and use selective breeding to increase coral resilience in the face of rising ocean temperatures.
