The purpose of the present study was to evaluate the capacity of a specific microalga (MACC-612, Nostoc linckia ) biomass and plant growth-promoting bacteria (PGPB) separately and together to improve crop growth and promote soil health. The research used a factorial design within a completely randomised block framework, featuring four replications for three consecutive years across different fields. The experiment utilised three levels of microalga (control, 0.3 g/L of N. linckia , MACC-612, and 1 g/L of N. linckia , MACC-612) and three levels of bacterial strains (control, Azospirillum lipoferum and Pseudomonas fluorescens ). The result demonstrated that the use of N. linckia and PGPB separately or jointly as soil treatment resulted in a substantial improvement in chlorophyll, plant biomass, soil humus, and nitrogen, depending on the environmental conditions of the years. The combined use of N. linckia and PGPB results in an improvement in dry leaf weight by 35.6–107.3% at 50 days after sowing (DAS) and 29.6–49.8% at 65 DAS, compared to the control group. Furthermore, the studies show that the synergistic application of N. linckia at 0.3 g/L, in conjunction with A. lipoferum , significantly improved total nitrogen and (NO 3 − + NO 2 − )-nitrogen, registering increases of 20.7–40% and 27.1–59.2%, respectively, during the study period. The most effective synergistic combination was identified through the application of 0.3 g/L of N. linckia along with A. lipoferum . Hence, application of biofertilisers through synergistic combinations of two or more microorganisms, such as microalgae and bacteria, holds promise in improving crop chlorophyll, growth, and soil nitrogen.

This study investigates the novel application of Spermine as a bio-stimulant to improve sweet corn ( Zea mays L. var. saccharata ) resilience under hydroponic water deficit conditions. Four genotypes (Dessert, Messenger, Tyson, and Royalty) were treated with Spermine (0.2 mM foliar application), polyethylene glycol 6000 (8% and 12%), and their combinations. The impacts on growth parameters, photosynthetic performance, and oxidative stress markers were evaluated. Spermine significantly enhanced biomass parameters, counteracting the severe reductions caused by PEG-induced water deprivation. In the Dessert and Tyson genotypes, total biomass increased by 145%, while it increased by 118% in Messenger and 110% in Royalty when treated with Spermine under severe water deprivation. However, Spermine treatment application did not recorded higher differences compared to control under non water deficit conditions. In the Dessert genotype, root length increased by 36.6% under combined treatment compared to 12% PEG alone. Spermine also mitigated reductions in shoot length, improved by 90.6% and specific leaf area, with a notable 272.6% increase in Tyson under severe water deficit. Photosynthetic performance, including chlorophyll and carotenoid levels, was enhanced, with a 103.1% increase in relative chlorophyll content in Dessert under severe water deprivation. Spermine also reduced oxidative damage, as indicated by a 48.7% decrease in malondialdehyde levels in Tyson, and increased peroxidase activity, enhancing antioxidant defense in Messenger under severe water deprivation. The quantum efficiency of Photosystem II, which was significantly reduced by water deficit, showed substantial improvement with Spermine treatment, with increases of 107.2% in Tyson and 99.4% in Royalty under moderate water deprivation. These results highlight the potential of Spermine as an effective strategy to improve sweet corn resilience under water-limited conditions, offering a novel approach for sustainable crop management.

In order to better understand the effects of arbuscular mycorrhizal fungus Claroideoglomus etunicatum and Indole-3-acetic acid (IAA) on the growth and chemical composition of vetiver grass (Vetiveria zizanioides) under salt stress, a factorial experiment was conducted in a completely randomized design with three replications. The experiment included four NaCl levels (0, 8, 16, and 24 decisiemens per meter (dS/m)) and four levels of treatments (no amendment application, application of IAA, application of C. etunicatum, and interaction of IAA and C. etunicatum) with three replications. The results of the experiment showed that the addition of sodium chloride increased the concentration of proline and the activities of catalase, peroxidase, and superoxide dismutase enzymes. The application of the growth regulator (IAA) and C. etunicatum significantly increased the fresh and dry weight (101%) of shoots, dry weight of roots, and the concentration of macro- and micro-elements in shoots under salinity condition (99.82% phosphorus; 9.79% Iron). The application of mycorrhiza and auxin significantly reduced the concentration of proline and the activities of catalase, peroxidase, and superoxide dismutase enzymes. In general, the addition of IAA and C. etunicatum to roots under salt stress conditions can improve growth and increase the concentration of some nutrients in vetiver shoots.

Developing strategies to enhance wheat’s resilience to salinity is critical for maintaining yield in affected regions. This study investigates the potential of chitosan-proline (Cs-Pro) and chitosan-glycine (Cs-Gly) nanoparticles in mitigating salt stress in salt-tolerant Heydari and salt-sensitive Sepahan wheat cultivars, with a special question on genotype-dependent differences. Plants were treated with nanoparticles at concentrations of 0, 200, and 400 mg L⁻¹ under salt stress levels of 0, 200, and 400 mM NaCl. The salt-tolerant Heydari cultivar exhibited superior adaptability to saline conditions, in addition reacted more positively to nanoparticle treatments. Results demonstrated significant physiological improvements, including increased relative water content (RWC), enhanced chlorophyll content and elevated proline levels, especially after 400 mg L⁻¹ Cs-Pro treatment. Oxidative stress markers, such as malondialdehyde (MDA) and hydrogen peroxide, were substantially reduced, while antioxidant enzyme activity was boosted. Certain stress-responsive genes (e.g., TaADC , TaPxPAO , TaSAMDC , TaSPDS , TaSOS1 , TaNHX1 ) were upregulated, highlighting the importance of ionic balance and polyamine metabolism in improved stress tolerance. The application of Cs-Pro and Cs-Gly nanoparticles presents a promising approach to enhance wheat’s salinity tolerance by improving physiological, biochemical, and molecular responses.

However, their regulatory effect on epigenetics is still not clear. The impact of exogenous putrescine in wheat leaves was investigated to reveal novel insights into the intricate relationship between polyamines and DNA methylation. Since the outcome of putrescine treatment may vary depending on the light quality, the experiment was performed under both white and blue light, and MeDIP-seq method was applied to reveal the global methylation profile. Metabolite profiling revealed distinct changes induced by blue light and/or putrescine, and that the effect of putrescine in most cases was dominant under blue light. Blue light also exerted strong effects on methylation, and putrescine application could slightly induce further changes. Putrescine had a higher impact under white light, namely parallel with increased leaf spermidine level, a lower level of up-methylated genes involved in cellular component, but a higher level of down-methylated genes involved in molecular function and biological processes occurred compared to the blue light. Our results demonstrated that putrescine excess has a regulatory role in DNA methylation. These findings are also useful in understanding the relationship between polyamine metabolism and light conditions. LA - English DB - MTMT ER -
