CLE peptides control Medicago truncatula nodulation locally and systemically.
The CLAVATA3/embryo-surrounding region (CLE) peptides control the fine balance between proliferation and differentiation in plant development. We studied the role of CLE peptides during indeterminate nodule development and identified 25 MtCLE peptide genes in the Medicago truncatula genome, of which two genes, MtCLE12 and MtCLE13, had nodulation-related expression patterns that were linked to p...
متن کاملEthylene Inhibitors Restore Nodulation to sym 5 Mutants of Pisum sativum L. cv Sparkle.
The sym 5 mutants of pea, Pisum sativum L. cv Sparkle, do not differ in growth habit from their normal parent and nodulate poorly at a root temperature of 20 degrees C. If inhibitors of ethylene formation or action (Co(2+), aminoethoxyvinylglycine, or Ag(+)) are added to the substrate, nodulation of the sym 5 mutants is increased. Similar treatments of four other mutant sym lines do not restore...
متن کاملEffect of exogenous flavonoids on nodulation of pea (Pisum sativum L.).
Selected flavonoids that are known as inducers and a suppressor of nodulation (nod) genes of the symbiotic bacterium Rhizobium leguminosarum bv. viciae were tested for their effect on symbiosis formation with garden pea as the host. A solid substrate was omitted from the hydroponic growing system in order to prevent losses of flavonoids due to adsorption and degradation. The presumed interactio...
متن کاملDNA methylase from Pisum sativum.
DNA methylase activity was detected in nuclei from pea shoots. The enzyme can only be extracted by low-salt treatment if the nuclei are pretreated with micrococcal nuclease. Only a single enzyme was detected, and it was purified to a specific activity of 1620 units/mg of protein. It has an Mr of 160,000 on gel filtration and SDS/PAGE. Pea DNA methylase methylates cytosine in all four dinucleoti...
متن کاملThe isoperoxidases of Pisum sativum.
The heterogeneity of the peroxidases in peas was examined by starch gel electrophoresis. Comparisons were made between tall and dwarf cultivars and among organ systems developed in light and darkness. Isoperoxidase bands could be grouped as cathodic, anodic and near-neutral (at pH 9.0) types. The cathodic set stained well with guaiacol oxidation products whereas some anodic bands reacted prefer...
