Journal ArticleDOI
Organization, structure and symbiotic function of rhizobium meliloti nodulation genes determining host specificity for alfalfa
Beatrix Horvath,Eva Kondorosi,Michael John,Jürgen Schmidt,I. Török,Zoltan Györgypal,Ilona Barabas,Ursula Wieneke,Jeff Schell,Adam Kondorosi +9 more
TL;DR: In R. meliloti, four nodulation genes determining plant host-range specificity and have been identified hsnABC and D, which determine plant-specific infection through root hairs: hsnD is required for host-specific root hair curling and nodule initiation while the hsn ABC genes control infection thread growth from the root hairs.
Journal ArticleDOI
Extensive regions of homology in front of the two hsp70 heat shock variant genes in Drosophila melanogaster.
TL;DR: The DNA sequence of a complete hsp70 † gene of the 87A7 type and of the adjacent regions from both variants, extending to 1·2 × 10 3 bases upstream from the start of the messenger coding region, is presented.
Journal ArticleDOI
Nucleotide sequence of Rhizobium meliloti nodulation genes
TL;DR: Comparison of the R. meliloti nodA, B, C nucleotide and amino acid sequences with those from R. leguminosarum shows 69-72% homology, clearly demonstrating the high degree of conservation of common nod genes in these Rhizobium species.
Journal ArticleDOI
Extensive Rearrangements in the Mitochondrial DNA in Somatic Hybrids of Nicotiana tabacum and Nicotiana knightiana
Ferene Nagy,I. Török,Pal Maliga +2 more
TL;DR: Mitochondrial DNA was studied in the leaves of Nicotiana tabacum+Nicotiana knightiana somatic hybrids, finding novel patterns can be explained by new combinations of unaltered parental mtDNA molecules, and by genetic recombination.
Journal ArticleDOI
Nucleotide sequence of the R.meliloti nitrogenase reductase (nifH) gene
I. Török,Adam Kondorosi +1 more
TL;DR: Comparison of the R.meliloti nifH nucleotide and amino acid sequences with those from different nitrogen-fixing organisms showed that the amino acids sequences are more conserved than the nucleotide sequences.
