Non-rhizobial nodulation in legumes
Legume Rhizobium associations are undoubtedly form the most important N2-fixing symbiosis and play a subtle role in contributing nitrogen and maintaining/improving soil fertility. A great diversity in the rhizobial species nodulating legumes has been recognized, which belongs to α subgroup of proteobacteria covering the genera, Rhizobium, Sinorhizobium (renamed as Ensifer), Mesorhizobium, Brady...
متن کاملKorngold and Jonathan Sprent
Unprimed T cells transferred to heavily irradiated H-2-compatible mice cause a high incidence of lethal graft-vs.-host disease (GVHD)a in certain strain combinations (1-3). GVHD in this setting is a consequence of mature post-thymic donor T cells responding to the multiple minor histocompatibility antigen (minor HA) differences of the host. With the combination of CBA and B10.BR (both H-2~), do...
متن کاملA Phylogenetically Conserved Group of Nuclear Factor-Y Transcription Factors Interact to Control Nodulation in Legumes.
The endosymbiotic association between legumes and soil bacteria called rhizobia leads to the formation of a new root-derived organ called the nodule in which differentiated bacteria convert atmospheric nitrogen into a form that can be assimilated by the host plant. Successful root infection by rhizobia and nodule organogenesis require the activation of symbiotic genes that are controlled by a s...
متن کاملTransient susceptibility of root cells in four common legumes to nodulation by rhizobia.
Root cells of four common legumes were found to remain susceptible to nodulation by rhizobia for only a short period of time. Delayed inoculation experiments conducted with these legume hosts indicated that the initially susceptible region of the root became progressively less susceptible if inoculations were delayed by a few hours. Profiles of the frequency of nodule formation relative to mark...
متن کاملPolyploidy Did Not Predate the Evolution of Nodulation in All Legumes
BACKGROUND Several lines of evidence indicate that polyploidy occurred by around 54 million years ago, early in the history of legume evolution, but it has not been known whether this event was confined to the papilionoid subfamily (Papilionoideae; e.g. beans, medics, lupins) or occurred earlier. Determining the timing of the polyploidy event is important for understanding whether polyploidy mi...
