Haber’s invention of the synthesis of ammonia from its elements is one of the cornerstones of modern civilization. For nearly a century, agriculture has come to rely on synthetic nitrogen fertilizers produced from ammonia. This large-scale production is now supporting nearly half of the world’s population through increased food production. But whilst the use of synthetic nitrogen fertilizers brought enormous benefits, including those of the Green Revolution, the world needs to disengage from our...

Abstract The taxonomic diversity of forty-two Rhizobium strains, isolated from nodules of faba bean grown in Egypt, was studied using 16S rRNA sequencing, multilocus sequence analyses (MLSA) of three chromosomal housekeeping loci and one nodulation gene ( nodA ). Based on the 16S rRNA gene sequences, most of the strains were related to Rhizobium leguminosarum , Rhizobium etli , and Rhizobium radiobacter (syn. Agrobacterium tumefaciens ). A maximum likelihood (ML) tree built from the concatenated...

This chapter reports the findings of a Working Group on how atmospheric nitrogen (N) deposition affects both terrestrial and freshwater biodiversity. Regional and global scale impacts on biodiversity are addressed, together with potential indicators. Key conclusions are that: the rates of loss in biodiversity are greatest at the lowest and initial stages of N deposition increase; changes in species compositions are related to the relative amounts of N, carbon (C) and phosphorus (P) in the plant ...

Extending the symbiotic nitrogen-fixing capability of legume crops with nitrogen-fixing bacteria to non-legume crops, particularly the cereals, would increase the extent of biological nitrogen (N) fixation and reduce the need for synthetic N fertilizers; excess N from N fertilizers causes many environmental impacts including a contribution to the greenhouse effect, acid rain and biodiversity loss. The first step required to achieve symbiotic N fixation in non-legume crops is to establish N-fixin...

Two barley (Hordeun vulgare L.) genotypes, Radical and Cwb, with good to moderate levels of resistance to powdery mildew were crossed with a highly susceptible cultivar (Afzal) to determine the genetics of resistance. The parents, Fl, F2 and F3 generations of each of the two crosses, were evaluated for powdery mildew resistance in the glasshouse and field at the College of Agriculture in Karaj during 2000. The x 2 analysis of the segregating ratios in the F3 generations indicate d that the resis...

: The successful fusion of plant protoplasts and animal cells depends on a variety of factors. A method using high pH, high Ca2+ concentration and raised temperature has advantages over the polyethylene glycol method first used to fuse plant and animal cells. Electric field-induced fusion will perhaps be superior to both methods. The readiness with which the two different cytoplasms fuse was found to influence the success of interkingdom fusions; the high pH/high Ca2+ method leads to more rapid ...

Protoplasts capable of division and plant regeneration are now available for a large number of vegetable, oil and forage crops. However, routine hybrid production is not possible due to methodological limitations in selection and culture of hybrid cells. Recent improvement in techniques are the use of a double mutant as a universal hybridizer and the use of fluorescence activated cell sorter to recover hybrid cells. Interest is also centered on limited gene transfer by protoplast fusion. We prop...
