Arbuscular mycorrhiza (AM) is known to be a mutually beneficial plant-fungal symbiosis; however, the effect of mycorrhization heavily dependent on multiple biotic and abiotic factors. Therefore, for proper employment such symbiotic systems in agriculture, detailed understanding molecular basis plant developmental response needed. The aim this work was uncover physiological metabolic alterations pea ( Pisum sativum L.) leaves associated with at key stages. Plants cv. Finale were grown...
In pea (Pisum sativum L.), alleles of the Sym2 gene determine specificity interaction with nodule bacteria (rhizobia). The Sym2A allele present in landraces from Afghanistan provides higher selectiveness toward rhizobia than Sym2E European cultivars. Rhizobial strains possessing nodX can interact both and peas, while lacking only peas. Here, we studied previously obtained introgression line A33.18 bearing a homozygous state genome cultivar ‘Rondo’. has proved its high pot experiments. Genome...
Plants are continuously exposed to various biotic and abiotic factors that may trigger cascade reactions aimed at maintaining homeostasis. One of the most important components plant protection from is synthesis antimicrobial peptides (AMPs). AMPs a large group present in insects, animals plants. Plant innate immunity provided by different families categorized according sequence similarity, number order amino acid residues, tertiary structure mature peptide. also participate response stresses...
Intensive exchange of nutrients is a crucial part the complex interaction between host plant and fungi within arbuscular mycorrhizal (AM) symbiosis. For first time, present study demonstrates how inoculation with AMF Rhizophagus irregularis affects pea (Pisum sativum L.) root metabolism at key stages development. These correspond to days 21 (vegetation), 42 (flowering initiation), 56 (fruiting-green pod). Metabolome profiling was carried out by means state-of-the-art GC-MS technique. The...
Various legume plants form root nodules in which symbiotic bacteria (rhizobia) fix atmospheric nitrogen after differentiation into a named bacteroids. In some species, bacteroid is promoted by defensin-like nodule-specific cysteine-rich (NCR) peptides. NCR peptides have best been studied the model Medicago truncatula Gaertn., while many other legumes relevant information still fragmentary. Here, we characterize gene family pea ( Pisum sativum L.) using genomic and transcriptomic data. We...
In garden pea (Pisum sativum L.), several symbiotic genes are known to control the development of mutualistic symbioses with nodule bacteria (NB) and arbuscular mycorrhizal fungi (AMF). Here, we studied whether allelic state was associated growth parameters plants under single inoculation NB double + AMF. Using different statistical methods, analyzed dataset obtained from a pot experiment that involved 99 cultivars, 10 which were characterized as having shortened internodes due presence...
Pea (Pisum sativum L.), like most legumes, forms mutualistic symbioses with nodule bacteria and arbuscular mycorrhizal (AM) fungi. The positive effect of inoculation is partially determined by the plant genotype, thus, pea varieties high low symbiotic responsivity have been described, but molecular genetic basis this trait remains unknown. Here, we compare symbiotically responsive breeding line ‘Triumph’ grain its parental cultivars ‘Vendevil’ (a donor responsivity) ‘Classic’ agriculturally...

A shift in the metabolic profiles of leaves and roots mycorrhized pea plants towards control at earlier stages development was revealed. Thus, mycorrhization led to retardation plant development.
The garden pea (Pisum sativum L.), like most members of Fabaceae family, is capable forming symbioses with beneficial soil microorganisms such as nodule bacteria (rhizobia), arbuscular mycorrhizal (AM) fungi and plant growth promoting (PGPB). autoregulation nodulation (AON) system known to play an important role in controlling both the number nodules level root colonization by AM via root-to-shoot signaling mediated CLAVATA/ESR-related (CLE) peptides their receptors. In pea, mutations genes...
Background. The active and careless applying of antibiotics in medicine agriculture leads to the emergence resistance existing antimicrobial drugs, which reduces effectiveness their use. One ways solve this problem is development new based on plant peptides with activity, for example defensins (which identified all plants) NCR that are specifically synthesized nodules some leguminous plants.
 Materials methods. In present study, a meta-assembly transcriptome was constructed publicly...
Mutualistic symbioses formed by garden pea have been studied with use of ‘omic’ technologies in order to gain a new understanding molecular mechanisms beneficial effect that microsymbionts on seed yield and quality.

One of the actual problems modern agriculture is crop loss due to various biotic and abiotic factors.In plants there a multicomponent protection system, including formation protective barriers, activation reaction hypersensitivity synthesis antimicrobial peptides, which are low molecular weight compounds showing broad spectrum activity against fungi, bacteria viruses.This group consists several groups defensins, one most common classes peptides detectable in all living organisms.Defensins...
Uptake of mineral nutrients from the soil is challenge plant survival.In particular, availability such macro-elements as nitrogen and phosphorus limiting factor for growth development.Some genera overcome this limitation by establishing symbiotic relationships with microorganisms.A remarkable example symbiosis one between legumes rhizobia -a group fixing bacteria.Rhizobial penetration into roots a specific host causes initiation specialized organ, nodule.Within cells nodule free-living...
Background. A major problem of the environmental pollution with heavy metals, including cadmium, requires an intensive study molecular and genetic mechanisms underlying tolerance plants to these toxic substances. In this we present a comparative analysis expression stress-related genes in two pea genotypes contrasting cadmium.
 Materials methods. unique mutant SGECdt, characterized by increased initial line SGE were used. Gene was analyzed Real Time PCR. Results. cadmium increase genes,...
