Small bacterial genomes are believed to be evolutionarily derived from larger genomes through massive loss of genes and are usually associated with symbiotic or pathogenic lifestyles. It is therefore ...
摘要 2004年首次在南海北部海域使用选择性代谢抑制剂技术进行了Synechococcus和Prochlorococcus生长率和被摄食消亡率的研究。研究结果表明，Synechococcus高丰度值出现在次表层(15 m或20 m)，位于温跃层之上，高生长率往往出现在丰度最大值水层上方；Prochlorococcus丰度在夏季出现次表层最大值，与温跃层深度基本一致，表层生长率高于真光层底部。Syn...
