Phosphorus is an essential macronutrient that supports plant energy metabolism, nucleic acid synthesis, and signal transduction. Despite its abundance in soil organic matter, modern agriculture remains dependent on finite rock phosphate sources, raising concerns over long-term sustainability environmental pollution. A significant portion of phosphorus exists the form phytate, which inaccessible to plants due their inability produce phytase enzymes. This review explores two integrated...

Soil is the largest terrestrial carbon reservoir, with microorganisms playing a pivotal role in organic matter decomposition and stabilization. Drought, intensified by climate change, alters microbial dynamics soil cycling. This study investigates effects of drought-induced stress on community composition, allocation, biochemical properties agricultural forest soils Bangladesh. Soils from drought-prone maize field semi-natural site Kushtia, Bangladesh, were incubated mesocosms under control...

Microorganisms utilize intricate chemical signaling mechanisms to communicate both within and across species, influencing a wide range of physiological behaviors ecological interactions. Among these mechanisms, quorum sensing stands out as pivotal strategy that bacteria employ detect population density coordinate gene expression in collective manner. These systems are mediated by autoinducers other secondary metabolites, such peptides, fatty acids, terpenoids, alkaloids. molecules not only...

The ubiquitin-proteasome system (UPS) is a fundamental regulatory mechanism maintaining cellular proteostasis through the targeted degradation of proteins. Beyond its canonical role in protein turnover, UPS governs diverse biological processes, including cell cycle control, DNA repair, immune responses, and stress adaptation. Dysregulation components increasingly recognized as driving force pathogenesis numerous diseases, such cancer, neurodegenerative disorders, metabolic dysfunctions,...

Sustainable pest management is vital for promoting agricultural productivity while preserving environmental health. This study investigated the integration of plant-based control methods with DNA (eDNA) metabarcoding to develop eco-friendly strategies. Soil, plant, and air samples were collected from organic, agroecological, conventional farms across Bangladesh analyze microbial diversity. Plant extracts neem (Azadirachta indica), garlic (Allium sativum), tobacco (Nicotiana tabacum) prepared...

Abstract Seaweed contained health functional polysaccharides and polyphenols. Five extracts were prepared from red seaweed Melanothamnus somalensis ; two of these aqueous at 20°C (F1) 70°C (F2), followed by acid (F3), alkali (F4) acid-washed (F5) treatments. Molecular characteristics measured high-performance liquid chromatography Fourier transform infrared (FTIR) analyses. Health functionality was determined sulfate polyphenol contents, thermal modulated differential scanning calorimetry....
