Hydrogenase genes are uncommon and highly conserved in Rhizobium leguminosarum bv. viciae

Hydrogenase genes are uncommon and highly conserved in Rhizobium leguminosarum bv. viciae - FEMS MicroBiology Letters, 253(1), p.83-88, 2005 .

A screening for hydrogen uptake (hup)genes in Rhizobium leguminosarum bv. viciae isolates from different locations within Spain identified no Hup+ strains, confirming the scarcity of the Hup trait in R. leguminosarum. However, five new Hup+ strains were isolated from Ni-rich soils from Italy and Germany. The hup gene variability was studied in these strains and in six available strains isolated from North America. Sequence analysis of three regions within the hup cluster showed an unusually high conservation among strains, with only 0.5-0.6
