FP22092Nanotechnology for endorsing abiotic stresses: a review on the role of nanoparticles and nanocompositions

Talha Javed 0000-0003-2986-9992, Rubab Shabbir, Sadam Hussain 0000-0002-2684-6368, Muhammad Asad Naseer, Irsa Ejaz, Muhamamd Moaaz Ali, Sunny Ahmar and Ahmed Fathy Yousef
pp. 831-849

Abiotic stress, due to both natural and anthropogenic activities, alters the soil–plant–atmosphere continuum, which adversely affects crop growth, development, and productivity. Abiotic stresses, including heavy metals, salts, and temperature extremes, cause a significant reduction in crop yields worldwide. There is an imperative need for environmentally friendly techniques to combat these stresses and improve agricultural sustainability. Nanomaterials, both nanoscale materials and nanocomposites, are the magic bullets showing the ability to alleviate the constraints associated with environmental stresses.

Reactive oxygen species metabolism is detailed under normal versus stressed conditions, elaborating on the modes and process of uptake and translocation of nanoparticles. The two-fold regulatory roles of nanoparticles are discussed. A molecular dissection of the role of nanoparticles is presented, in controlling transcriptomic expression and modulating molecular crosstalk with other growth regulators, ions, reactive nitrogen species and other signalling molecules. Potential roles and regulation of nanoparticles and their utility for green synthesis within a sustainable agricultural industry are explored.

FP23021Zinc and nano zinc mediated alleviation of heavy metals and metalloids in plants: an overview

Sanaullah Jalil 0000-0001-9070-3989, Muhammad Mudassir Nazir, Qurban Ali, Faisal Zulfiqar 0000-0001-5428-5695, Anam Moosa, Muhammad Ahsan Altaf 0000-0001-7257-479X, Abbu Zaid 0000-0002-2090-0212, Muhammad Nafees, Jean Wan Hong Yong 0000-0003-3325-8254 and Xiaoli Jin 0000-0003-4829-176X

Heavy metals and metalloids pollution in the environment, particularly in soils, has gained increased attention globally. Zn2+ is a crucial nutrient for tolerance against heavy metals. This review illustrates the vital role of Zn2+ and nano Zn in plants and explains the knowledge of their impact in alleviating HMMs toxicity in plants.

FP22274Mesoporous silica nanoparticle-induced drought tolerance in Arabidopsis thaliana grown under in vitro conditions

Thi Linh Chi Tran, Albert Guirguis 0000-0003-2328-9428, Thanojan Jeyachandran, Yichao Wang 0000-0002-6295-6492 and David M. Cahill 0000-0002-2556-0528
pp. 889-900

This study analysed the effect of mesoporous silica nanoparticles and simulated drought conditions on Arabidopsis seed germination and seedling growth. The plants were subjected to drought through the use of the osmolyte, polyethylene glycol. Treatment with nanoparticles enhanced seed gemination and plant growth under both non-stressed and drought conditions. We propose that these nanoparticles provide an alternative approach for increased drought tolerance through making water and nutrients more readily available.

FP23036Silver nanoparticles protect tillering in drought-stressed wheat by improving leaf water relations and physiological functioning

Muhammad Sarwar, Muhammad Farrukh Saleem, Najeeb Ullah 0000-0001-6775-3937, Muhammad Jahanzaib Khan, Hamza Maqsood, Hassaan Ahmad, Asif Tanveer and Muhammad Shahid 0000-0001-5956-655X
pp. 901-914

Wheat (Triticum aestivum) crops suffer significant grain yield losses when water supplies are affected during the early developmental phases. This study shows varying levels of drought stress impaired carbon assimilation, tiller formation and final grain yield of wheat genotypes. In contrast, exogenously applied silver nanoparticles (AgNPs) restored plant growth and grain yield formation, suggesting their potential to protect wheat crops from drought-induced injury.

FP22140Efficacy of priming wheat (Triticum aestivum) seeds with a benzothiazine derivative to improve drought stress tolerance

Arwa Abdulkreem AL-Huqail 0000-0002-1226-499X, Muhammad Hamzah Saleem 0000-0002-3658-770X, Baber Ali 0000-0003-1553-2248, Muhammad Azeem, Sahar Mumtaz, Ghulam Yasin, Romina Alina Marc and Shafaqat Ali 0000-0003-0272-7097
pp. 915-931

Approximately 33% of the arable land around the world, including Pakistan, is vulnerable to drought, affecting the yield and productivity of cereal crops. It is hypothesised that benzothiazine (BTh) could alleviate abiotic stress caused by drought through salicylic acid accumulation in plants. We found that wheat (Triticum aestivum L.) seeds primed with BTh derivatives could alleviate oxidative stress by increasing antioxidants, proline, soluble sugars and increasing fluxes of essential nutrients under drought stress.

FP23085Effects of iron oxide nanoparticles (Fe3O4) and salinity on growth, photosynthesis, antioxidant activity and distribution of mineral elements in wheat (Triticum aestivum)

Vladimir D. Kreslavski 0000-0002-6789-5721, Alexander N. Shmarev, Anatoly A. Ivanov, Sergey K. Zharmukhamedov, Valeria Strokina, Anatoly Kosobryukhov, Min Yu, Suleyman I. Allakhverdiev 0000-0002-0452-232X and Sergey Shabala 0000-0003-2345-8981
pp. 932-940

Soil salinity significantly affects productivity of agricultural systems. This work shows that plant treatment with iron oxide nanoparticles (Fe3O4 NPs) may be a promising solution for reducing the negative impact of soil salinity on plant performance. It is concluded that Fe3O4 NPs can enhance plant growth by improving photosynthetic characteristics, antioxidant balance and the availability of iron and manganese ions, under conditions of soil salinisation.

Salt toxicity negatively affected physiochemical activities and growth of bottle gourd, Lagenaria siceraria L. Application of zinc oxide nanoparticless mitigated salt stress and enhanced biochemical stress-markers and antioxidant activity of plants. Plants treated with zinc oxide nanoparticles exhibited improved growth and reduced salt toxicity.

Nanostructure gold nanoparticles (Au NPs) are biological active materialsthat has gained significant interest in the field of biomedicine. We investigated a novel and cost-effective way to synthesise Au NPs from mediated Viscum album Linn plant extract, where the plant metabolites act as stabilising and reducing agents. The mediated V. album plant extracts and synthesised Au NPs were screened against gram-positive and gram-negative (Enterobacter, Salmonella typhi, Escherichiacoli and Bacillus subtilis) bacterial strains, confirming their antibacterial potential.
