A method for analyzing volatile constituents from plant leaves with gas chromatography/mass spectrometry (GC/MS) coupled with solid-phase microextraction (SPME) was developed. The volatile compounds from the plant leaves inside a sealed flask maintained at 45 degrees C in a water bath were efficiently extracted with Polyacrylate (85 microm) SPME fibers prior to perform GC/MS analysis. The GC/MS analysis indicated that the volatile compounds from the plant leaves which is easy to be damaged by Tetraychus vienneis include relative large amounts of cis-3-hexenyl ester acetic acid, cis-3-hexenyl ester butanoic acid and alpha-famesene. These compounds were preliminarily confirmed to be accountable for attracting Tetraychus vienneis. This finding may lead to identify biological species for preventing and treating Tetraychus vienneis.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

Soil contamination with toxic heavy metals [such as aluminum (Al)] is becoming a serious global problem due to the rapid development of the social economy. Although plant growth-promoting rhizo-bacteria (PGPR) are the major protectants to alleviate metal toxicity, the study of these bacteria to ameliorate the toxic effects of Al is limited. Therefore, the present study was conducted to investigate the combined effects of different levels of (5 ppm and 10 ppm) of accession number of MT123456 on plant growth and biomass, photosynthetic pigments, gas exchange attributes, oxidative stress and response of antioxidant compounds (enzymatic and nonenzymatic), and their specific gene expression, sugars, nutritional status of the plant, organic acid exudation pattern and Al accumulation from the different parts of the plants, which was spiked with different levels of Al [0 µM (i.

Drought conditions severely curtail the ability of plants to accumulate biomass due to the closure of stomata and the decrease of photosynthetic assimilation rate. Additionally, there is a shift in the plant's metabolic processes toward the production of metabolites that offer protection and aid in osmoadaptation, as opposed to those required for development and growth. To limit water loss via non-stomatal transpiration, plants adjust the load and composition of cuticle waxes, which act as an additional barrier.

In this study, stems and leaves of the papaya plant were employed to prepare a high-quality porous adsorbent carbonization and chemical activation using phosphoric acid. This adsorbent demonstrates superior adsorption capabilities for the efficient removal of hazardous alizarin red s (ARS) and methylene blue (MB) dyes. Thus, it contributes to waste reduction and promotes sustainable practices in environmental remediation, aligning with global efforts to develop sustainable materials that address water pollution while supporting circular economy principles.
