Aluminum toxicity in acidic soils threatens rice (Oryza sativa L.) cultivation, hindering agricultural productivity. This study explores the potential of plant growth-promoting rhizobacteria (PGPR) as a novel and sustainable approach to mitigate aluminum stress rice. Two varieties, INIAP-4M SUPREMA I-1480, were selected for controlled laboratory experiments. Seedlings exposed varying concentrations (0, 2, 4, 8, 16 mM) presence four PGPR strains: Serratia marcescens (MO4), Enterobacter asburiae (MO5), Pseudomonas veronii (R4), protegens (CHAO).

Soil acidification adversely affects plant growth and development by decreasing the accessibility of roots to essential nutrients. Thus, it decreases crop yield. However, there has been a lack systematic research on how soil influences nutrient absorption in eggplant cultivated greenhouse. To address this gap, an experiment was conducted greenhouse with seven different acidity levels (4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5), achieved adding dilute H2SO4. The findings indicated that organic matter (SOM) content at pH 4.5 decreased 49% - 50% compared 7.0 7.5. In addition, exchangeable aluminum (Al3+) electrical conductivity (EC) were highest 4.5, increases 82 -88 mg kg-1 1.78 1.82 ms cm-1, respectively, total nitrogen (TN), phosphorus (TP), potassium (TK) declined as increased, reaching their lowest 0.59, 0.42, 3.79 g 4.5. Among available nutrients, only did not exhibit significant variation across treatments. macro elements consistently decreased, while concentrations trace (Fe, Cu, Zn) increased rising acidity; conversely, other (B, Mo, Mn) decreased. amounts calcium (Ca2+) magnesium (Mg2+) 5.0 dropped 61% 66% 70% 78%, Further analyses values between 6.0 reduced capacity eggplant, observed Mantel confirmed significantly uptake. This provides both theoretical insights practical guidance for effective management vegetable

Heavy metals in soil can inflict direct damage on plants growing within it, adversely affecting their growth height, root development, leaf area, and other physiological traits. To counteract the toxic impacts of heavy plant mitigate metal stress through mechanisms such as chelation, vacuolar compartmentalization, regulation transporters, enhancement antioxidant functions. WRKY transcription factors (TFs) play a crucial role development well responses to both biotic abiotic stresses; notably, is classified an stressor. An increasing number studies have highlighted significant proteins regulating across various levels. Upon entry ions into cells, production reactive oxygen species (ROS) triggered, leading phosphorylation activation TFs MAPK cascade signaling. Activated then modulate processes by upregulating or downregulating expression downstream genes confer tolerance plants. This review provides overview research advancements regarding ion stress—including cadmium (Cd), arsenic (As), copper (Cu)—and aluminum (Al) toxicity.
