Nodulation and nitrogen fixation mutants of pea, Pisum sativum

Nodulation and nitrogen fixation mutants of pea, Pisum sativum 122 74 74 6 6 K. C. Engvild Agricultural Research Department Risø National Laboratory DK-4000 Roskilde Denmark Summary The 36 mutants which did not nodulate and 24 mutants which formed inefficient nodules with no or very low acetylene reduction activity were isolated among 86,000 M 2 -seedlings of ‘Finale’ pea, Pisum sativum L., after treatment with chemical mutagens. One mutant was found for approximately every 50 chlorophyll mutants. Most mutations were induced by ethyl methanesulfonate; some by diethyl sulfate, ethyl nitrosourea and acidified sodium azide. Putative mutants were selected as nitrogen deficient plants, yellowing from the bottom and up, when M 2 seedlings were grown in sand with a Rhizobium mixture and PK fertilizer. The mutants were verified in the M 3 generation by acetylene reduction assay on intact plants. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png TAG Theoretical and Applied Genetics Springer Journals
