Trend analysis of reaction parameters and properties of plant-mediated green synthesized selenium nanoparticles using non-parametric statistical methods (Mann-Kendall trend test, Sen's slope estimator, ANOVA) and their applications in the modern world: a critical perspective.

Selenium nanoparticles (SeNPs) have garnered increased interest due to their significant role in human health, including the regulation of blood sugar levels, boosting the immune system, reducing oxidative stress, and other benefits. Conventional synthesis methods of SeNp employ the use of toxic chemicals and solvents, which are harmful to the environment; in contrast, the green synthesis method does not involve the use of any toxic chemicals. In this article, the green synthesis of SeNp using plant extracts, the influence of reaction parameters on their characteristic properties, and the application of SeNp in the present world are discussed.

Molecular identification of the fungal strain isolated from river water and characterization of the myco-coagulant produced by the strain are presented in this paper.

Jasmonate-Induced Defense Mechanisms in the Belowground Antagonistic Interaction Between and in Rice.

Next to their essential roles in plant growth and development, phytohormones play a central role in plant immunity against pathogens. In this study we studied the previously reported antagonism between the plant-pathogenic oomycete and the root-knot nematode , two root pathogens that co-occur in aerobic rice fields. In this manuscript, we investigated if the antagonism is related to imbalances in plant hormone levels, which could be involved in activation of plant defense.
