In a detailed study recently published in the journal Plant, Cell & Environment, a team of Chinese researchers has explored the molecular basis behind the cold resistance of Syntrichia caninervis. This moss, renowned for its ability to survive desiccation, freezing temperatures, and even gamma radiation, is considered a promising candidate for future Mars terraforming projects due to its demonstrated resilience in simulated Martian settings.
To understand how the moss manages cold stress, scientists performed RNA sequencing on samples hydrated and then exposed to temperatures of 4°C and -4°C. This process allowed them to monitor gene expression changes over time, revealing that pathways involved in sugar and energy metabolism, lipid metabolism, and antioxidation are crucial for the moss’s survival under cold conditions.
The research highlighted a significant up-regulation in genes related to photosynthesis, indicating an adaptive response to maintain essential metabolic functions at low temperatures. Among the various genes studied, A-5 DREB genes, particularly ScDREBA5, experienced an increase in expression by nearly 1,000-fold, marking them as central to the moss’s cold endurance mechanism.
The study underscores not only the intricate cellular responses that enable Syntrichia caninervis to thrive in extreme environments but also the potential to apply this knowledge in the engineering of more resilient crops that could succeed in similarly challenging conditions on Earth and beyond.
