Nitrogen fixation in legume nodules is crucial for plant growth and development. Therefore, this study aims to investigate the effects of nitric oxide [S-nitrosoglutathione (GSNO)] and silicon [sodium metasilicate (Si)], both individually and in combination, on soybean growth, nodule formation, leghaemoglobin (Lb) synthesis, and potential post-translational modifications. At the V1 stage, soybean plants were treated for 2 weeks with 150 µM GSNO, and Si at concentrations of 1 mM, 2 mM, and 4 mM.

- Nitric oxide (NO) plays a crucial role in regulating NBS-LRR immune genes in plants, but previous studies lacked a comprehensive genome-wide analysis of these genes' responses to NO.
- The current research identified and characterized 29 NO-induced NBS-LRR genes from Arabidopsis thaliana, rice, maize, soybean, and tomato, examining their properties, structures, and interactions as well as their distribution across chromosomes.
- Results indicated that these genes possess various characteristics and functional domains, suggesting that NO mediates a diverse range of responses related to plant immunity and development.
Article Synopsis
- Nanoparticles, specifically chitosan-fulvic acid nanoparticles (Ch-FANPs), are being studied as eco-friendly alternatives to synthetic fertilizers for sustainable agriculture under climate change conditions.
- In an experiment, maize plants treated with a 100 μM concentration of Ch-FANPs showed improved growth and resilience against drought stress compared to those treated with chitosan or fulvic acid alone.
- The Ch-FANPs not only enhanced overall plant growth by 20% but also increased antioxidant activity and chlorophyll content, while reducing oxidative damage, indicating their potential as effective growth promoters and drought tolerance boosters in maize plants.
Soybean, a major legume crop, has seen a decline in its production owing to challenges in seed germination and the development of seedlings. Thus, in this study, we systematically investigated the influence of various chitosan-S-nitrosoglutathione (chitosan-GSNO) nanoparticle (0, 25, 50, and 100 µM) and Si (0, 0.5, and 1 mM) priming concentrations on soybean seed germination and seedling growth over five different priming durations (range: 1-5 h at each concentration).

Chitosan nanoparticles (CSNPs) have been used for the enhancement of plant growth and development. On the other hand, NO is an important signaling molecule that regulates several aspects of plant physiology under normal and stress conditions.

- Environmental pollutants like heavy metals can harm crops and are dangerous to human health because they get into our food.
- Plants can fight against these metals by using a special gas called nitric oxide (NO), which helps them stay healthy.
- New research is looking at tiny particles that release NO safely over time, which might be a better way to help plants deal with heavy metal stress than using older chemical methods.
Sustainable agriculture is increasingly being put in danger by environmental contamination with dangerous heavy metals (HMs), especially lead (Pb). Plants have developed a sophisticated mechanism for nitric oxide (NO) production and signaling to regulate hazardous effects of abiotic factors, including HMs. In the current study, we investigated the role of exogenously applied sodium nitroprusside (SNP, a nitric oxide (NO) donor) in ameliorating the toxic effects of lead (Pb) on rice.
