Genomic traces of symbiosis loss A between certain bacteria and their plant hosts delivers fixed nitrogen to the plants. Griesmann et al. sequenced several genomes analyze why nitrogen-fixing is irregularly scattered through evolutionary tree (see Perspective by Nagy). Various carried lost pathways that could have supported symbiosis. It seems this symbiosis, which relies on multiple complex interorganismal signaling, susceptible selection prone being over time. Science , issue p. eaat1743 ;...
Significance Fixed nitrogen is essential for plant growth. Some plants, such as legumes, can host nitrogen-fixing bacteria within cells in root organs called nodules. Nodules are considered to have evolved parallel different lineages, but the genetic changes underlying this evolution remain unknown. Based on gene expression nonlegume Parasponia andersonii and legume Medicago truncatula , we find that nodules these lineages may share a single origin. Comparison of genomes with those related...
Abstract Legumes balance nitrogen acquisition from soil nitrate with symbiotic fixation. Nitrogen fixation requires establishment of a new organ, which is cytokinin dependent developmental process in the root. We found biosynthesis central integrator, balancing signalling acquired nitrogen. Low conditions provide permissive state for induction by and thus nodule development. In contrast, high inhibitory to accumulation root zone susceptible formation. This reduction was further exacerbated...
Summary Nitrogen‐fixing nodulation occurs in 10 taxonomic lineages, with either rhizobia or Frankia bacteria. To establish such an endosymbiosis, two processes are essential: nodule organogenesis and intracellular bacterial infection. In the legume–rhizobium both guarded by transcription factor NODULE INCEPTION (NIN) its downstream target genes of NUCLEAR FACTOR Y (NF‐Y) complex. It is hypothesized that has a single evolutionary origin c . 110 Ma, followed many independent losses. Despite...
Rhizobium nitrogen-fixing nodule symbiosis occurs in two taxonomic lineages: legumes (Fabaceae) and the genus
Parasponia andersonii is a fast-growing tropical tree that belongs to the Cannabis family (Cannabaceae). Together with 4 additional species, it forms only known non-legume lineage able establish nitrogen-fixing nodule symbiosis rhizobium. Comparative studies between legumes and P. could provide valuable insight into genetic networks underlying root formation. To facilitate comparative studies, we recently sequenced genome established Agrobacterium tumefaciens-mediated stable transformation...
Abstract Rhizobium nitrogen-fixing nodules are a well-known trait of legumes, but also occur in other plant lineages either with rhizobium or the actinomycete Frankia as microsymbiont. The widely accepted hypothesis is that nodulation evolved independently multiple times, only few losses. However, insight evolutionary trajectory lacking. We conducted comparative studies using Parasponia (Cannabaceae), non-legume able to establish nitrogen fixing rhizobium. This revealed and legumes utilize...
