Abstract The implementation of agronomic activities, based on the use of biostimulants, is an important element of agroecological practices. Therefore, comprehensive research was carried on the use of biostimulants. A field experiment was performed in 2016–2018 with common bean of Mexican Black cultivar. In particular growing seasons, bean plants were treated with Kelpak SL (seaweed extracts) and Terra Sorb Complex (free amino acids) in the form of single and double spraying with two solutions concentrations. According to the obtained data, application of biostimulants increased the yield of bean. Better results were observed after the use of Kelpak SL. The application of preparations influenced nutritional and nutraceutical quality of bean seeds. Terra Sorb Complex caused the highest increase in proteins level. In the light of achieved data, biostimulants in similar level decreased the starch accumulation. The most promising results, in the context of nutraceutical value of bean, were obtained in the case of increasing level of fiber. A positive impact of biostimulants on the seeds antioxidant potential was noted, expressed by the increased synthesis of phenolics, flavonoid, anthocyanins and antioxidant activities. Results of this study, directly indicate economic benefits from the use of biostimulants, which are extremely important to the farmers.

Iron nanoparticles modulate photosynthesis without disturbing anti-oxidative profiling in mung bean plants; hence they could be used as a plant micronutrient.

Transient oxidative shock induced by pretreatment of leaves with H2O2 effectively increased chilling tolerance in mung bean and Phalaenopsis. Seedlings of the chilling-tolerant (V3327) cultivar of mung bean (Vigna�radiata L.) were employed to study the mechanism of H2O2-induced chilling tolerance. Pretreatment with 200 mM H2O2 increased survival rates of seedlings chilled at 4°C for 36 h from 30% to 70%. The same treatment also lowered the electrolyte leakage from 86% to 21%. Time-course analysis immediately after the treatment demonstrated that exogenous application of H2O2 did not alter the endogenous H2O2 level of the plants. This observation suggests that the primary receptor for the exogenous H2O2 is localized on the leaf surface or in some other way isolated from the endogenous H2O2 pool. Oxidative shock inhibited the induction of the antioxidant enzymes, ascorbate peroxidase and catalase; however, it substantially increased glutathione content both under chilling and control conditions. Combined pretreatment of mung bean plants with abscisic acid and H2O2 showed no synergistic effect on glutathione content and decreased survival rate relative to treatment with either compound alone. These results suggest that the H2O2-induced chilling tolerance in these plants might be mediated by an elevation of glutathione content and is independent of the ABA mechanism of chilling protection.

В статье приведены результаты исследования биосовместимости мутантных штаммов клубеньковых и PGPR бактерий (ризобактерий) с целью их совместного применения для культур маша и фасоли. По результатам проведенных исследований определены штаммы, проявившие контактную прогрессию и нейтралитет - Pseudomonas putidaМ-1 и Phyllobacterium sp. 35М; штаммы Bacillus subtilis М-2 и Chryseobacterium rhizoplanae 1М оказались наиболее перспективными в отношении совместного культивирования.Таким образом, подобраны консорциумы на основе мутантных штаммов азотфиксирующих и ростостимулирующих бактерий Pseudomonas putida М-1 и Chryseobacterium rhizoplanae для растений маша и Bacillus subtilis М-2 и Phyllobacterium sp. 35М - для растений фасоли. Полученные результаты открывают возможность комбинирования мутантных штаммов PGPR с ростостимулирующей активностью (Pseudomonas putida М-1, Bacillus subtilis М-2) и клубеньковыхбактерий (Phyllobacterium sp. 35М, Chryseobacterium rhizoplanae) с азотфиксирующей активностью с целью получения на их основе биопрепарата с сочетанными свойствами. The article presents the results of a study of the biocompatibility of mutant strains of nodule and PGPR bacteria with the aim of their combined use for mung bean and beans. According to the results of the studies, the strains that showed contact progression and neutrality were identified - Pseudomonas putida M-1 and Phyllobacterium sp. 35M; strains Bacillus subtilis M-2 and Chryseobacterium rhizoplanae 1M proved to be the most promising for co-cultivation. Thus, consortia were selected based on mutant strains of nitrogen-fixing and growth-stimulating bacteria Pseudomonas putida M-1 and Chryseobacterium rhizoplanae for mung bean and Bacillus subtilis M-2 and Phyllobacterium sp.35M for bean plants. The results obtained open up the possibility of combining mutant PGPR strains with growth-stimulating activity (Pseudomonas putida M-1, Bacillus subtilis M-2) and nodule bacteria with nitrogen-fixing activity (Phyllobacterium sp. 35M, Chryseobacterium rhizoplanae) in order to obtain a biological product with combined properties on their basis.

A transaminase has been isolated and purified from young mung bean plants (Phaseolus aureus Roxb.). The enzyme catalyzes the transamination of phenylalanine in the presence of α-ketoglutarate with the production of equimolar amounts of phenylpyruvate and glutamate. Tyrosine and tryptophan also serve as substrates, and relative rate measurements indicate that only one enzyme is involved. In addition to α-ketoglutarate the enzyme also utilizes pyruvate, and to some extent glyoxylate and oxaloacetate as amino acceptors. The enzyme is stable in solution at 0–4 °C for several weeks, and acetone powders of the young plants stored at 0–4 °C retained their activity for several months. The enzyme is inhibited by precipitation with ammonium sulphate, and the activity is lost after freezing.
