Microplastic contamination in agricultural soils from mulch films and organic amendments: Transformation mechanism, soil-Biota toxicity, and future perspectives.

Microplastic contamination has emerged as one of the most pressing environmental challenges of our time. While extensive research has been conducted on microplastics in aquatic ecosystems, there remains a significant knowledge gap regarding their presence and impact in terrestrial environments, particularly in agricultural soils, despite microplastic contamination on land being 4 to 23 times higher than in aquatic systems. These soils are increasingly polluted with microplastics from various sources, including plastic mulch films, organic amendments, irrigation, and atmospheric deposition.

Which SDM Model, CLIMEX vs. MaxEnt, Best Forecasts Distribution at a Global Scale under Climate Change Scenarios?

A precise evaluation of the risk of establishing insect pests is essential for national plant protection organizations. This accuracy is crucial in negotiating international trade agreements for forestry-related commodities, which have the potential to carry pests and lead to unintended introductions in the importing countries. In our study, we employed both mechanistic and correlative niche models to assess and map the global patterns of potential establishment for under current and future climates.

Flavonoids: a review on biosynthesis and transportation mechanism in plants.

In recent years, significant progress has been made in understanding the biosynthetic pathway and regulation of flavonoids through forward genetic approaches. However, there remains a notable gap in knowledge regarding the functional characterization and underlying processes of the transport framework responsible for flavonoid transport. This aspect requires further investigation and clarification to achieve a comprehensive understanding.

Chemical characterization and evaluation of the neuroprotective potential of studies and behavioral tests in scopolamine-induced memory compromised rats.

In the current study, we investigated the phytochemical and neuropharmacological potential of , an indigenous least characterized plant widely distributed in deserted areas of Pakistan. The crude extract of the whole plant (IS.CR) was preliminary tested for the existence of polyphenol content, antioxidant and anticholinesterase potential followed by detailed chemical characterization through UHPLC-MS.

Pharmacological investigation of activities pertaining to modulation of gastrointestinal, respiratory and cardiovascular parameters by Indigofera argentea in experimental models.

Indigofera argentea is widely used for the management of gastrointestinal, respiratory and cardiac disorders. This study was done to explore scientific basis of its uses. Aqueous methanolic extract of Indigofera argentea and its fractions were studied on isolated tissues of rabbit's jejunum, trachea, aorta and atrium.

Pharmacological Modulation of Smooth Muscles and Platelet Aggregation by .

Traditionally, in the Southern Asian countries, is a widely used plant for the management of various ailments such as gastrointestinal, respiratory, and cardiac disorders, but it lacks proof on a scientific basis, and therefore, this is the major emphasis of the current research work. Crude extract of (Pc.Cr) was preliminary analyzed for the presence of different classes of bioactive molecules.

Phytolith Formation in Plants: From Soil to Cell.

Silica is deposited extra- and intracellularly in plants in solid form, as phytoliths. Phytoliths have emerged as accepted taxonomic tools and proxies for reconstructing ancient flora, agricultural economies, environment, and climate. The discovery of silicon transporter genes has aided in the understanding of the mechanism of silicon transport and deposition within the plant body and reconstructing plant phylogeny that is based on the ability of plants to accumulate silica.

A CAM- and starch-deficient mutant of the facultative CAM species Mesembryanthemum crystallinum reconciles sink demands by repartitioning carbon during acclimation to salinity.

In the halophytic species Mesembryanthemum crystallinum, the induction of crassulacean acid metabolism (CAM) by salinity requires a substantial investment of resources in storage carbohydrates to provide substrate for nocturnal CO(2) uptake. Acclimation to salinity also requires the synthesis and accumulation of cyclitols as compatible solutes, maintenance of root respiration, and nitrate assimilation. This study assessed the hierarchy and coordination of sinks for carbohydrate in leaves and roots during acclimation to salinity in M.
