Mowing facilitated Pb accumulation in bermudagrass by mediating root radial transport.

College of Landscape Architecture, Sichuan Agricultural University, Chengdu, Sichuan, 611130, China. Electronic address:
Moderate mowing of the shoot is an effective strategy for improving Pb-contaminated soil remediation using bermudagrass. However, the mechanisms by which mowing facilitates Pb uptake and accumulation remain insufficiently understood. Root radial transport is critical in efficient heavy metal uptake and translocation in plants and is influenced by root physiological-biochemical characteristics.

Activated CDC42-associated kinase 1 (ACK1), encoded by the TNK2 gene, is a cytoplasmic non-receptor tyrosine kinase whose aberrant activation correlates positively with cancer severity. Recent research has revealed the functional relevance of this oncokinase - it is an epigenetic regulator that drives cancer progression in multiple malignancies. Although ACK1 is an attractive target for therapeutic intervention, incomplete knowledge of its diverse signaling mechanisms and the lack of specific inhibitors have challenged its clinical success.

Background: Whereas uncomplicated labral tears with preserved fibers can be effectively treated with use of labral repair techniques, complex tears and hypoplastic labra require labral reconstruction. Standard reconstruction techniques feature grafted tissue that is added to existing, deficient tissue or that is utilized to replace a hypoplastic labrum entirely. However, such approaches utilizing allografts or remote autografts are limited because they often necessitate extensive debridement of the existing labrum to prepare a site for graft implantation, an approach that can damage and devascularize the chondrolabral junction.

The widespread presence of plastic pollution has become a challenge for both aquatic and terrestrial plants. Notably, nanoplastics (NPs) have been found to enter the root tissues and translocate to different organs of plants; however, most previous studies were performed using crop or vegetable seedlings, and the extent NPs accumulation in fruit tree plants, particularly citrus, and their impacts remains unclear. This study was designed to fill this gap by determining the uptake and accumulation of green, fluorescent polystyrene nanoplastics (PS-NPs) of two different sizes (20 nm and 50 nm in diameter) in citrus rootstock ('US-942') in an aeroponic system and their impact on plant growth and physiological functions, nutrient uptake, and root system architectural and anatomical traits.

The harmful impacts of micro(nano)-plastics (MNPs) on plants have gained significant attention in the last decades. Plants have a greater tendency to aggregate positively charged (+ve) MNPs on leaf surfaces and root tips, and it can be more challenging to enter the plant body than the negatively charged (-ve) MNPs. MNPs <20 nm can directly cross the cell wall and enter mainly via leaf stomata and root crack portion.
