蓝藻通过氧合光合作用的发明和通过内共生作用赋予真核生物的光合作用生活方式，形成了两个主要的进化转变。与理解这些转变密切相关的信息被印记在蓝藻基因组中，但破译它通过横向基因转移(LGT)变得复杂。在这里，我们报告了形态上最复杂的真分支蓝藻的基因组序列，以及霍夫曼尼单胞藻PCC7110的基因组序列，它含有12,356个蛋白质，是目前已知的基因最丰富的原核生物。我们调查了蓝藻进化的组成部分，这些成分已经垂直遗传、水平转移并捐赠给起源于叶绿体的真核生物。垂直分量表明水裂解光合作用的淡水来源。水平分量网络显示，60%的蓝藻基因家族已经受到LGT的影响。从蓝藻获得的植物核基因定义了611个多基因家族的下限频率，这反过来又指定了重氮营养蓝藻谱系具有与叶绿体祖先最相似的基因集合。
Cyanobacteria forged two major evolutionary transitions with the invention of oxygenic photosynthesis and the bestowal of photosynthetic lifestyle upon eukaryotes through endosymbiosis. Information germane to understanding those transitions is imprinted in cyanobacterial genomes, but deciphering it is complicated by lateral gene transfer (LGT). Here, we report genome sequences for the morphologically most complex true-branching cyanobacteria, and for Scytonema hofmanni PCC 7110, which with 12,356 proteins is the most gene-rich prokaryote currently known. We investigated components of cyanobacterial evolution that have been vertically inherited, horizontally transferred, and donated to eukaryotes at plastid origin. The vertical component indicates a freshwater origin for water-splitting photosynthesis. Networks of the horizontal component reveal that 60% of cyanobacterial gene families have been affected by LGT. Plant nuclear genes acquired from cyanobacteria define a lower bound frequency of 611 multigene families that, in turn, specify diazotrophic cyanobacterial lineages as having a gene collection most similar to that possessed by the plastid ancestor.
