Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]

open access: yesFEBS J
Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...
