| Abstract: | Background Glutamine synthetase (GS) is essential for ammonium assimilation and the biosynthesis of glutamine. The three GS gene families
(GSI, GSII, and GSIII) are represented in both prokaryotic and eukaryotic organisms. In this study, we examined the evolutionary
relationship of GSII from eubacterial and eukaryotic lineages and present robust phylogenetic evidence that GSII was transferred
from γ-Proteobacteria (Eubacteria) to the Chloroplastida. |
