Genetic organization of the hydrogen uptake (hup) cluster from Rhizobium leguminosarum.

Journal of bacteriology - 1 Mar 1990

Leyva A, Palacios J M, Murillo J, Ruiz-Argüeso T

Abstract excerpt

In symbiosis with peas, Rhizobium leguminosarum UPM791 induces the synthesis of a hydrogen uptake (Hup) system that recycles hydrogen generated in nodules by nitrogenase. A cosmid (pAL618) containing hup genes from this strain on a 20-kilobase-pair (kb) DNA insert has previously been isolated in our laboratory (A. Leyva, J. M. Palacios, T. Mozo, and T.Ruiz-Argüeso, J. Bacteriol. 169:4929-4934, 1987). Here we show...
