Nano-enabled agriculture is a topic of intense research interest. However, our knowledge how nanoparticles enter plants, plant cells, and organelles still insufficient. Here, we discuss the barriers that limit efficient delivery at whole-plant single-cell levels. Some commonly overlooked factors, such as light conditions surface tension applied nano-formulations, are discussed. Knowledge gaps regarding cell uptake nanoparticles, effect electrochemical gradients across organelle membranes on nanoparticle delivery, analyzed The importance controlling factors size, charge, stability, dispersibility when properly designing nanomaterials for plants outlined. We mainly focus understanding travel in cells major promoting better nanoparticle–plant interactions. also provide suggestions design nano-enabled agriculture.

Alleviation of drought and salt stress in vegetables: crop responses and mitigation strategies

Plant Growth Regulation, Journal Year: 2022, Volume and Issue: 99(2), P. 177 - 194

Published: Oct. 25, 2022

Abstract In recent decades, the demand for vegetables has increased significantly due to blooming global population. Climate change affected vegetable production by increasing frequencies and severity of abiotic biotic stresses. Among stresses, drought salinity are major issues that possess severe threats on production. Many (e.g., carrot, tomato, okra, pea, eggplant, lettuce, potato) usually sensitive salt stress. The defence mechanisms plants against stress have been extensively studied in model plant species field crops. Better understanding susceptibility stresses will help towards development more tolerant genotypes as a long-term strategy these However, intensity challenges also warrants immediate approaches mitigate enhance short term. Therefore, this review enlightens updated knowledge responses (physiological molecular) potentially effective strategies Moreover, we summarized different technologies such seed priming, genetic transformation, biostimulants, nanotechnology, cultural practices adopted under We propose conventional breeding, engineering, crop management should be combined generate resistance cultivars adopt smart cultivation sustainable changing climate.

Alleviation of salt stress complications in plants by nanoparticles and the associated mechanisms: An overview

Plant Stress, Journal Year: 2023, Volume and Issue: 7, P. 100134 - 100134

Published: Jan. 24, 2023

High salinity is a serious problem in agriculture, causing significant yield losses crops every year by inflicting damage both through the osmotic effect reducing water uptake plants, and excess ions entering into transpiration stream cell injury. The application of various bioactive nanoparticles particular shapes, sizes, concentrations has been shown to give protection against salt stress different crop improving growth parameters, seed germination, root anatomy, yield, biochemical profile. molecular mechanisms behind this phenomenon are still unknown, but research revealed that can alter several gene expressions (including AREB, SOS2, DDF2) associated with stress. Hence, potential alternative strategy management agriculture receiving huge attention nowadays. Here we have reviewed effective so far investigated, their for better production major challenges this. This review intended be helpful insight mitigation nanoparticle-mediated strategies understanding nanoparticle-salinity relations. Prospects using mitigate also discussed here.

Efficient delivery of nanoparticles (NPs) to plants is important for agricultural application. However, date, we still lack knowledge about how NPs' charge matters its translocation pathway, i.e., symplastic and apoplastic pathways, in plants. In this study, synthesized used negatively charged citrate sourced carbon dots (C-CDs, −37.97 ± 1.89 mV), Cy5 coated C-CDs (Cy5-C-CDs, −41.90 2.55 positively PEI (P-CDs, +43.03 1.71 P-CDs (Cy5-P-CDs, +48.80 1.21 mV) investigate the role surface charges coatings on employed pathways (symplastic pathways) NPs Our results showed that, different from higher fluorescence intensity Cy5-P-CDs extracellular than intracellular space, Cy5-C-CDs was similar between space cucumber cotton roots. It suggests that CDs were translocated via both but mainly pathway. Furthermore, our root applied demonstrated leaf did (8.09 0.99 vs 3.75 0.23) (7.27 1.06 3.23 0.22), indicating have a efficiency do CDs. should be noted not affect cell activities, ROS level, photosynthetic performance cotton, showing good biocompatibility. Overall, study only figured out transportation roots compared with employment pathway CDs, also found could more efficiently imparting negative NPs, at least efficient crops.

Abstract Pumpkin CmoNAC1 enhances salt tolerance in grafted cucumbers. However, the potential interactions with other proteins that may co-regulate alongside have yet to be explored. In this study, we identified pumpkin CmoDREB2A as a pivotal transcription factor interacts synergistically co-regulation of tolerance. Both factors were observed bind each other’s promoters, forming positive regulatory loop their transcription. Knockout root resulted reduced cucumbers, whereas overexpression demonstrated opposite effect. Multiple assays our study provided evidence protein interaction between and CmoNAC1. Exploiting interaction, facilitated binding promoters CmoRBOHD1, CmoNCED6, CmoAKT1;2, CmoHKT1;1, inducing H2O2 ABA synthesis increasing K+/Na+ ratio cucumbers under stress. Additionally, also promoted CmoHAK5;1/CmoHAK5;2 further contributing homeostasis. summary, these findings reveal crucial mechanism complex enhancing
