Deficiency Potentiates ABA-Mediated Mitigation of Heavy Metal Toxicity in Plants.

Identifying key genes that regulate plant responses to heavy metals (HMs) is crucial for developing effective strategies to limit HM accumulation. While abscisic acid (ABA) is known to mediate stress responses, the molecular mechanisms linking ABA signaling to HM tolerance are poorly understood. This study revealed as the critical receptor-like kinase that integrates ABA-mediated signaling with HM uptake regulation, a novel role not previously reported.

A dose-dependent effect of UV-328 on photosynthesis: Exploring light harvesting and UV-B sensing mechanisms.

Benzotriazole ultraviolet (UV) stabilizers (BUVs) have emerged as significant environmental contaminants, frequently detected in various ecosystems. While the toxicity of BUVs to aquatic organisms is well-documented, studies on their impact on plant life are scarce. Plants are crucial as they provide the primary source of energy and organic matter in ecosystems through photosynthesis.

Graphene oxide influences transfer of plasmid-mediated antibiotic resistance genes into plants.

As an emerging contaminant, antibiotic resistance genes (ARGs) are raising concerns about its significant threat to public health. Meanwhile, graphene oxide (GO), which also has a potential ecological damage with increasingly entering the environment, has a great influence on the transfer of ARGs. However, little is known about the effects mechanisms of GO on the migration of antibiotic resistance genes (ARGs) from bacteria into plants.

Synergistic interplay between ABA-generating bacteria and biochar in the reduction of heavy metal accumulation in radish, pakchoi, and tomato.

Heavy metal (HM) contamination is an environmental concern that threatens the agricultural product safety and human health. To address this concern, we developed a novel strategy involving the synergistic application of Azospirillum brasilense, a growth-promoting rhizobacterium which produces abscisic acid (ABA), and biochar to minimize HM accumulation in the edible parts of vegetable crops. Compared to A.

N fertilizers promote abscisic acid-catabolizing bacteria to enhance heavy metal phytoremediation from metalliferous soils.

Bacterial-assisted phytoextraction is an attractive strategy to enhance the phytoremediation efficiency of heavy metal (HM)-contaminated soils. In the present study, we investigated the synergistic effects of N fertilizers and abscisic acid (ABA)-catabolizing bacteria on the HM (Cd, Zn, and Pb) phytoremediation efficiency of Brassica juncea L. (B.

[Expression and significance of TGF-beta1 and BMP-2 in mandibular callus].

Objective: To investigate the expressions of transforming growth factor beta1 (TGF-beta1) and bone morphogenetic protein-2 (BMP-2) in human mandible fracture callus and their quantity changes in the process of healing.

Method: Thirty callus samples from the fractured mandible bone stumps were collected during operation, and two callus samples were collected from the angle-square jaw patients as controls. The expressions of TGF-beta1 and BMP-2 were test by the immunohistochemistry technic-SABC-staining in different periods of human fractured mandibular callus and in osseous tissue of normal angle of mandible.
