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...
The legume-rhizobium symbiosis results in nitrogen-fixing root nodules, and their formation involves both intracellular infection initiated the epidermis nodule organogenesis inner cell layers. NODULE INCEPTION (NIN) is a nodule-specific transcription factor essential for processes. These NIN-regulated processes occur at different times locations root, demonstrating complex pattern of spatiotemporal regulation. We show that regulatory sequences sufficient epidermal process are located within...
Parasponia represents five fast-growing tropical tree species in the Cannabaceae and is only plant lineage besides legumes that can establish nitrogen-fixing nodules with rhizobium. Comparative analyses between allows identification of conserved genetic networks controlling this symbiosis. However, such studies are hampered due to absence powerful reverse tools for Parasponia. Here, we present a fast efficient protocol Agrobacterium tumefaciens-mediated transformation CRISPR/Cas9 mutagenesis...
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
The frequency difference between two oppositely propagating spin waves can be used to probe several interesting magnetic properties, such as the Dzyaloshinskii-Moriya interaction (DMI). Propagating wave spectroscopy is a technique that very sensitive this difference. Here, we show elements are important optimize devices for measurement. We demonstrate wide strips, there need de-embedding. Additionally, these large parasitic antenna-antenna coupling obfuscates any transmission signal, which...
Nodule symbiosis with diazotrophic Frankia or rhizobium occurs in plant species belonging to ten taxonomic lineages within the related orders Fabales, Fagales, Cucurbitales, and Rosales. Phylogenomic studies indicate that this nitrogen-fixing nodulation trait has a single evolutionary origin. In legume model plants, molecular interaction between microsymbiont is mapped significant degree. A specific LysM-type receptor kinase, LjEPR3 Lotus japonicus MtLYK10 Medicago truncatula, was found act...
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...
We describe the identification and molecular characterization of a novel variant O(1) allele ABO blood group locus. The was found in young child by analyzing maternal DNA we were able to show that meiotic recombination event between O(1v-3) B(1-1) alleles recreated O(1)/B hybrid allele. Further intron 6 sequences delineated putative breakpoint nucleotide position 42 163 intron. propose O(1variant) should be named O(1v-7) is combination exon from 7
