extreme-environments
Extreme environments are habitats characterized by conditions hostile to most life, such as extreme temperatures, high pressure, drought, salinity, or unusual atmospheric composition. Studying how plants survive and adapt to these harsh conditions reveals the molecular, physiological, and genetic mechanisms underlying stress tolerance. These insights are critical for developing crops resilient to climate change and expanding agriculture into marginal lands.

Scientists discovered a surprisingly rich community of hydrocarbon-eating bacteria living deep beneath the ocean floor in the world's deepest trench. These microbes are actively breaking down complex carbon compounds miles below the surface, revealing unknown pathways of carbon cycling in extreme environments.
Hydrocarbon-degrading bacteria were found active throughout a sediment core extending ~750 cm below the seafloor at a depth of 10,816 meters
The sediment contained high concentrations of mid- and long-chain hydrocarbons, suggesting significant in-situ carbon storage and turnover
Both culture-dependent and culture-independent methods confirmed diverse microbial metabolism, indicating multiple independent hydrocarbon degradation pathways coexist in hadal sediments
