Lessons from Extremophiles: Early Evolution and Border Conditions of Life

摘要: Modern prokaryotes are the only forms of life featuring organisms capable growth above 62°C, and inside each domain, first phylogenetic analyses singled out most extreme these thermophiles as earliest lines descent: Aquificales Thermotogales among Bacteria, different Euryarchaeota Crenarchaeota Archaea. A recent research study used a new algorithm automatically picking up “representative” proteins, including both ubiquitous non-ubiquitous but rather well-conserved proteins; here Thermotoga Aquifex remained together in basal position with weak bootstrap support. result more than 3 billion years evolution, during which further adaptation has certainly occurred, molecular adaptations to thermophily look elaborated living we can investigate. Temperature is an all-pervasive factor straightforward effects on physical state universal solvent, remain liquid allow suitably adapted grow. The world extremophiles offers similar test cases; some obvious ones concern halophily thermophily, conditions that impose whole proteome.
