Hamed HA, Abeed AHA, Geioushy RA, Fouad OA, El-Mahdy MT. Innovative auxin-micronutrient based nanocomposites (IAA-Fe 2O 3NPs and IAA-Mn 2O 3NPs) shield strawberry plants from lead toxicity. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2024; 219:109429. [PMID: 39718285 DOI: 10.1016/j.plaphy.2024.109429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/10/2024] [Revised: 09/16/2024] [Accepted: 12/17/2024] [Indexed: 12/25/2024]
Abstract
Smart nanohybrid technology with potential advantages to plants has recently been developed formanaging the widespread pollution of heavy metals. Herein, we disclose a novel strategy to combat Pb stress in strawberry (Fragaria spp. cv. Fertona) through a newly designed nano-based system that conjugates indole acetic acid (IAA) with nanoparticles (NPs) of iron (Fe) and manganese (Mn) micronutrients, forming IAA-Mn2O3NPs (IAA-MnNPs) and IAA-Fe2O3NPs (IAA-FeNPs) nanocomposites and illuminates the underlying mechanisms involved. NPs were synthesized, yielding cubic Mn2O3 NPs (50 nm) and spheric Fe2O3 NPs (30-40 nm), and evidenced by various characterization techniques. The incorporation of IAA hormone to the surface of NPs was examined using FT-IR spectroscopy. Results showed that Pb harshly hindered strawberry growth and promoted stress oxidative markers, i.e., MDA and ROS byproducts. Notably, the application of IAA-MnNPs and IAA-FeNPs at 50 and 100 ppm moderated the deleterious effects of Pb toxicity in strawberry plants, as revealed by enhanced growth indices, photosynthetic traits, membrane stability, and nutrient profiles of Mn and Fe, as well as higher IAA accumulation. This is pertinent to lessen Pb accumulation and impaired Pb-induced oxidative stress. The decrease in Pb content holds to be filled in with escalating Pb-detoxification mechanisms by enhancing enzymatic antioxidants' activities such as catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione peroxidase (GPX), glutathione S-transferases (GST), phenylalanine ammonia-lyase (PAL), nitrate reductase (NR), and attenuating polyphenol oxidase (PPO). On top of that, IAA-MnNPs and IAA-FeNPs elevated the content of non-enzymatic antioxidants, e.g., ascorbic acid and flavonoids, and enhanced the accumulation of chelating agents, i.e., proline, glutathione, and phytochelatins. We posit that the novel-engineered IAA-MnNPs and IAA-FeNPs nanohybrids present an effective approach that could fend off Pb stress in strawberry plants in contaminated croplands.

Populus euphratica CPK21 Interacts with NF-YC3 to Enhance Cadmium Tolerance in Arabidopsis. Int J Mol Sci 2024; 25:7214. [PMID: 39000320 PMCID: PMC11240976 DOI: 10.3390/ijms25137214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Revised: 06/27/2024] [Accepted: 06/27/2024] [Indexed: 07/16/2024] Open
Abstract
The toxic metal cadmium (Cd) poses a serious threat to plant growth and human health. Populus euphratica calcium-dependent protein kinase 21 (CPK21) has previously been shown to attenuate Cd toxicity by reducing Cd accumulation, enhancing antioxidant defense and improving water balance in transgenic Arabidopsis. Here, we confirmed a protein-protein interaction between PeCPK21 and Arabidopsis nuclear transcription factor YC3 (AtNF-YC3) by yeast two-hybrid and bimolecular fluorescence complementation assays. AtNF-YC3 was induced by Cd and strongly expressed in PeCPK21-overexpressed plants. Overexpression of AtNF-YC3 in Arabidopsis reduced the Cd inhibition of root length, fresh weight and membrane stability under Cd stress conditions (100 µM, 7 d), suggesting that AtNF-YC3 appears to contribute to the improvement of Cd stress tolerance. AtNF-YC3 improved Cd tolerance by limiting Cd uptake and accumulation, activating antioxidant enzymes and reducing hydrogen peroxide (H2O2) production under Cd stress. We conclude that PeCPK21 interacts with AtNF-YC3 to limit Cd accumulation and enhance the reactive oxygen species (ROS) scavenging system and thereby positively regulate plant adaptation to Cd environments. This study highlights the interaction between PeCPK21 and AtNF-YC3 under Cd stress conditions, which can be utilized to improve Cd tolerance in higher plants.

Abstract
The present study utilized the National Health and Nutrition Examination Survey (NHANES) database to examine the relationship between serum levels of heavy metals and Diabetic retinopathy (DR) in individuals aged over 30 years with type 2 diabetes mellitus (T2DM) in the United States. A cross-sectional analysis was conducted on 1583 individuals with T2DM from the NHANES 2011-2020, including 331 individuals in the DR group and 1252 individuals in the non-DR group. We collected data on serum levels of heavy metals, DR, and serum albumin for descriptive statistics, linear regression, and logistical regression analysis. After adjusting for age, gender, race and other factors, there was no statistically significant association between blood cadmium, selenium, mercury, or lead and DR. However, serum manganese (Mn) and DR had a significant negative association (β = - 0.2045, 95% CI = - 0.3484, - 0.0606). Serum albumin partially modulated the indirect influence of serum Mn on the incidence of DR, accounting for 12.80% of the association between serum Mn and DR. There was a negative association between serum Mn levels and the prevalence of DR in people with T2DM. Mn intake at least in this study has a little influence on the onset and development of DR.

The comparative effects of manganese nanoparticles and their counterparts (bulk and ionic) in Artemisia annua plants via seed priming and foliar application. FRONTIERS IN PLANT SCIENCE 2023; 13:1098772.

Abstract
The world has experienced an unprecedented boom in nanotechnology. Nanoparticles (NPs) are likely to act as biostimulants in various plants due to having high surface/volume value. However, understanding the actual effect of NPs is essential to discriminate them from other counterparts in terms of being applicable, safe and cost-effective. This study aimed to assay the impact of manganese(III) oxide (Mn2O3)-NPs via seed-priming (SP) and a combination of SP and foliar application (SP+F) on Artemisia. annua performance at several times intervals and comparison with other available manganese (Mn) forms. Our findings indicate that SP with MnSO4 and Mn2O3-NPs stimulates the processes that occur prior to germination and thus reduces the time for radicle emergence. In both applications (i.e., SP and +F), none of the Mn treatments did show adverse phytotoxic on A. annua growth at morpho-physio and biochemical levels except for Mn2O3, which delayed germination and further plant growth, subsequently. Besides, from physio-biochemical data, it can be inferred that the general mechanism mode of action of Mn is mainly attributed to induce the photosynthetic processes, stimulate the superoxide dismutase (SOD) activity, and up-regulation of proline and phenolic compounds. Therefore, our results showed that both enzymatic and non-enzymatic antioxidants could be influenced by the application of Mn treatments in a type-dependent manner. In general, this study revealed that Mn2O3-NPs at the tested condition could be used as biostimulants to improve germination, seedling development and further plant growth. However, they are not as effective as MnSO4 treatments. Nonetheless, these findings can be used to consider and develop Mn2O3-NPs priming in future studies to improve seed germination and seedling quality in plants.

Abstract
The regulation of reactive oxygen species (ROS) levels in plants is ensured by mechanisms preventing their over accumulation, and by diverse antioxidants, including enzymes and nonenzymatic compounds. These are affected by redox conditions, posttranslational modifications, transcriptional and posttranscriptional modifications, Ca2+, nitric oxide (NO) and mitogen-activated protein kinase signaling pathways. Recent knowledge about protein-protein interactions (PPIs) of antioxidant enzymes advanced during last decade. The best-known examples are interactions mediated by redox buffering proteins such as thioredoxins and glutaredoxins. This review summarizes interactions of major antioxidant enzymes with regulatory and signaling proteins and their diverse functions. Such interactions are important for stability, degradation and activation of interacting partners. Moreover, PPIs of antioxidant enzymes may connect diverse metabolic processes with ROS scavenging. Proteins like receptor for activated C kinase 1 may ensure coordination of antioxidant enzymes to ensure efficient ROS regulation. Nevertheless, PPIs in antioxidant defense are understudied, and intensive research is required to define their role in complex regulation of ROS scavenging.

Mitochondrial HSC70-1 Regulates Polar Auxin Transport through ROS Homeostasis in Arabidopsis Roots. Antioxidants (Basel) 2022; 11:antiox11102035.

Abstract
Arabidopsis mitochondrial-localized heat shock protein 70-1 (mtHSC70-1) modulates vegetative growth by assisting mitochondrial complex IV assembly and maintaining reactive oxygen species (ROS) homeostasis. In addition, mtHSC70-1 affects embryo development, and this effect is mediated by auxin. However, whether mtHSC70-1 regulates vegetative growth through auxin and knowledge of the link between ROS homeostasis and auxin distribution remain unclear. Here, we found that mtHSC70-1 knockout seedlings (mthsc70-1a) displayed shortened roots, decreased fresh root weight and lateral root number, increased root width and abnormal root morphology. The introduction of the mtHSC70-1 gene into mthsc70-1a restored the growth and development of roots to the level of the wild type. However, sugar and auxin supplementation could not help the mutant roots restore to normal. Moreover, mthsc70-1a seedlings showed a decrease in meristem length and activity, auxin transport carrier (PINs and AUX1) and auxin abundances in root tips. The application of exogenous reducing agents upregulated the levels of PINs in the mutant roots. The introduction of antioxidant enzyme genes (MSD1 or CAT1) into the mthsc70-1a mutant rescued the PIN and local auxin abundances and root growth and development. Taken together, our data suggest that mtHSC70-1 regulates polar auxin transport through ROS homeostasis in Arabidopsis roots.
