Article
Full-text available
Multimodal spectroscopic imaging methods such as Matrix Assisted Laser Desorption/Ionization Mass Spectrometry Imaging (MALDI MSI), Fourier Transform Infrared spectroscopy (FT-IR) and Raman spectroscopy were used to monitor the changes in distribution and to determine semi quantitatively selected metabolites involved in nitrogen fixation in pea roo...

Chemically, the Nod factors (NFs) are lipochitooligosaccharides, produced mainly by bacteria of the Rhizobium genus. They are the main signaling molecules involved in the initiation of symbiosis between rhizobia and legume plants. Nod factors affect plant tissues at very low concentrations, even as low as 10–12 mol/L. They induce root hair deformat...
Article
Full-text available
Nod factors are lipochitooligosaccharides (LCOs) produced by rizobia and act as molecular signals at the early stages of initiation of symbiosis with the legumes. Nod factors induce early symbiotic reactions on plant roots and initiate the development of specialized plant organs - nodules where biological nitrogen fixation occurs. Nod factor prepar...
Article
Full-text available
The importance of flavonoids in rhizosphere–legumes symbiosis has been recognized as critical. However, the limited data are available about their impact on soil microbial communities. In rhizosphere, it remains unclear whether flavonoids, mulch or their joint effects influence on soil microbial diversity and enzymes activity. Therefore, in this st...
Chapter
Biological nitrogen fixation is one of the most important physiological processes in which atmospheric nitrogen is reduced to ammonia by symbiotic bacteria called rhizobia belonging to α- and β-Proteobacteria. Legume plants (Fabaceae) enter into mutualistic symbiosis with nitrogen-fixing rhizobia which enable them to grow in nitrogen-limited agricu...
Article
Full-text available
Flavonoids and Nod factors (lipo-chitooligosaccharides) influence legume growth, plant–microbe communication and regulate microbial community. To assess the effects of pea (Pisum sativum) seed inoculation with flavonoids and Nod factors on microbial parameters, field study was performed on a Haplic Luvisol. Flavonoids were extracted from sprouted p...
Article

The growth and yield of peas cultivated on eight different soils, as well as the diversity of pea microsymbionts derived from these soils were investigated in the present study. The experimental plot was composed of soils that were transferred from different parts of Poland more than a century ago. The soils were located in direct vicinity of each...
Chapter
The response of pea var. Medal to treatment with Nod factors (LCOs) and mineral sulfur was estimated in a pot experiment with a completely randomized design. Foliar spraying of plants was performed at the 5–6 leaf stage (BBCH 15) at concentrations of 10−12 M dm−3 and 12 g S dm−3 for LCOs and sulfur, respectively. The use of these factors, both indi...
Article
Full-text available
Growth and symbiotic activity of legumes are mediated by Nod factors (LCO, lipo-chitooligosaccharides). To assess the effects of application of Nod factors on symbiotic activity and yield of pea, a two-year field experiment was conducted on a Haplic Luvisol developed from loess. Nod factors were isolated from Rhizobium leguminosarum bv. viciae stra...
Article
Full-text available
The responses of two pea genotypes to treatment with Rhizobium Nod factors were analysed in a pot experiment with a completely randomised design. The first-order factor was pea cultivar: Milwa and Klif, and the second-order factor was seed soaking: control (distilled water), solution-containing Nod factors (LCOs) at a concentration of 10 -12 M·dm -...
Article
Full-text available
Rhizobial lipochitooligosacharides (Nod factors) influence the development of legume roots, including growth stimulation, nodule induction and root hair curling. However, their effect on the green parts of plants is less known, therefore we evaluated seed and foliar application of an extract containing Nod factors on pea growth and yield. Pea plant...
Article
Full-text available
Nod factors are lipochitooligosaccharide (LCO) produced by soil bacteria commonly known as rhizobia acting as signals for the legume plants to initiate symbiosis. Nod factors trigger early symbiotic responses in plant roots and initiate the development of specialized plant organs called nodules, where biological nitrogen fixation takes place. Here,...

Full-text available
Background Rhizobium leguminosarum bv. viciae (Rlv) is a soil bacterium which can form nitrogen-fixing symbiotic relationships with leguminous plants. Numerous rhizobial strains found in soils compete with each other. Competition can occur both during the saprophytic growth phase in the rhizosphere and inside plant tissues, during the symbiotic ph...
Article
Full-text available
Rhizobium leguminosarum by. trifolii (Rlt) establishes beneficial root nodule symbiosis with clover. Twenty Rlt strains differentially marked with antibiotic-resistance markers were investigated in terms of their competitiveness and plant growth promotion in mixed inoculation of clover in laboratory experiments. The results showed that the studied...

Full-text available
Rhizobial symbiosis with leguminous plants affects the supply of organic nitrogen. Soil bacteria comprising members of the genera Rhizobium, Bradyrhizobium, Mesorhizobium, Sinorhizobium, and Azorhizobium, commonly referred to as rhizobia, are taxonomically diverse members of the α and β subclasses of the Proteobacteria. They possess the ability to...

Project
The project is to develop an innovative, ecological biofertilizer containing rhizobial metabolites, which are morphogens, stimulating activity of meristems inside different plant tissues, resulting in an increase in the number of nodules active in the biological nitrogen fixation.
