“…The result was in agreement with Luo et al [32], who found that zinc/cadmium-induced root exudates increased soil solution pH in the rhizosphere of hyperaccumulator Thlaspi caerulescens. Some studies generated the opposite results and showed that significant occurs at the rhizosphere interface to increase the effectiveness of rhizosphere soil nutrients (e.g., zinc, cadmium, iron, phosphorus, and potassium) and stimulate their uptake by plants [33][34][35][36]. Changes in pH variation owing to plants may be related to the charge balance at the soil-root interface.…”

Soil selenium (Se) speciation characteristics and their influence on the Se enrichment pattern and physiological characteristics of oilseed rape are poorly understood. We investigated dynamic changes in rhizosphere soil physicochemical properties, Se uptake and partitioning, biomass, and physiological indices in oilseed rape under five exogenous Se condition levels (0, 1.0, 2.5, 5.0, and 10.0 mg kg−1 Se in sodium selenite) using soil cultivation experiments. The rhizosphere pH and dissolved organic carbon in the soil solution were higher than those of the non-rhizosphere soil solution. The total Se, water-soluble Se, exchangeable Se, and organic Se contents in soils, as well as rapeseed root/leaf Se contents, significantly increased with increasing exogenous Se. Under 2.5 mg kg−1 Se, the biomass of rapeseed roots and leaves increased at the sixth week (82% and 58%) and eighth week (48% and 32%), respectively, reaching the highest level. Applications of 5.0 mg kg−1 Se at 6 and 8 weeks significantly increased the glutathione peroxidase activity (49%/82%), and decreased malondialdehyde content (23%/39%). Canonical correlation and ridge regression analyses showed that Se in the rapeseed roots/leaves significantly and positively correlated with water-soluble Se, exchangeable Se, and organic Se in rhizosphere soil. Overall, moderate-concentration Se soil application benefited oilseed rape growth (optimum = 2.5 mg kg−1 Se). Our findings reveal the response of oilseed rape to soil Se application based on plant growth and physiological traits, rhizospheric soil solution properties, and Se speciation transformation.

“…A wealth of literature supports the assertion that rhizosphere acidification is mediated by the PM H + -ATPase of plants. − These PM H + -ATPase hydrolyze adenosine triphosphate (ATP) to actively expel H + , thereby providing the proton motive force essential for the exudation of organic acids. , The PM H + -ATPase accounts for approximately 80% of the total membrane proteins in cells and is classified within the P-type ATPase family . It facilitates the extrusion of H + from the cytoplasm to the extracellular space during ATP hydrolysis, resulting in the acidification of the extracellular environment.…”

The plasma membrane (PM) H+-ATPase is crucial for a plant defense system. However, there is currently no consensus on whether the PM H+-ATPase plays a role in alleviating the toxic effects of herbicides on nontarget plants. We found that under the herbicide imazethapyr (IM) exposure, PM H+-ATPase activity in wheat roots increased by approximately 69.53%, leading to rhizosphere acidification. When PM H+-ATPase activity is inhibited, the toxicity of IM significantly increases: When exposed to IM alone, the total Fe content of wheat roots decreased by 29.07%, the relative Fe2+ content increased by 27.75%, and the ROS content increased by 27.74%. When the PM H+-ATPase activity was inhibited, the corresponding data under IM exposure were 37.36%, 215%, and 57.68%, respectively. This work delves into the role of PM H+-ATPase in mediating the detoxification mechanism in plants exposed to herbicides, offering new insights into enhancing crop resistance against herbicides.
