Impact of metal oxide nanoparticles on cotton (Gossypium hirsutum L.): a physiological perspective

Abstract

Cotton production substantiated a crucial part in the escalating economic development of many countries. To realize the increasing global demand for cotton, the emphasis should be laid on to improve cotton fiber growth and production. The bioengineered transgenic cotton proved expedient in resolving inadequacies of conventional cotton, but still required improvements to encounter heightened demand of textile industries. One possible solution pertaining to this has been provided by nanoscience in the form of metal or metal oxide nanoparticles. These metal oxide nanoparticles have easy access to the various parts of cotton plants through its transportation system, and thus significantly influence several parameters relative to the growth and production of cotton fiber. This review summarizes the distribution and accumulation of metal oxide nanoparticles in cotton plant and its impact on different plant growth-promoting factors, which resulted in the improved cotton yields. Graphical abstract Metal/metal-oxide nanoparticles have easy access to the various parts of cotton plant through its transportation system, and thus significantly influence its growth parameters, and hence the production of cotton fiber. This review summarizes the distribution and accumulation of metal oxide nanoparticles in cotton plants, and its impact on different plant growth promoting factors.

Changes in morphological traits, anatomical and molecular alterations caused by gamma-rays and zinc oxide nanoparticles in spinach (Spinacia oleracea L.) plant

“…It was observed that ZnO–NPs treatments produced higher photosynthetic pigments in the current study (Fig. 1 ) and this is in accordance with the findings reported in the literature (Singh et al 2021 ; Ragab et al 2022 ; Ramegowda et al 2013 ).…”

“…Results of the recent study (Table 3 ) displayed that seeds priming by ZnO–NPs could enhance spinach development, under gamma irradiation stress. Previous studies confirmed useful evidence to support the beneficial effects of nano-sized zinc to plants growth such as corn ( Zea mays ) (Neto et al 2020 ), cotton ( Gossypium hirsutum ) (Singh et al 2021 ) and chickpea ( Cicer arietinum ) (Burman et al 2013 ). Also, zinc is identified to be engaged in managing enzyme, proteins synthesis, cells elongation, modifiable membranes role, and improvement of plant resistance to environmental challenges (Cakmak 2008 ).…”

“…Zinc oxide nanoparticles significantly improved growth and photosynthetic effectiveness, and activate the antioxidant systems in tomato seedling (Faizan et al 2018 ). Cotton ( Gossypium hirsutum ) plants tested by ZnO–NPs established a considerable enhancement in biomass, shoots and roots length as well as roots area and this improvement was raised by rising of the ZO-NPs concentration (Singh et al 2021 ). There was a correlation between nutrients content, growth parameters and changing in nanoparticles concentrations.…”

Nanotechnology in sustainable agriculture: A double‐edged sword

“…130,137 Recently, NPs such as CuO, ZnO, TiO 2 , SnO 2 , CeO 2 , and Fe 2 O have been found to have a diverse negative impact on organisms. 138,139 However, the accumulation of NPs in soil has the potential to disrupt the soil and plant ecosystem, leading to negative impacts on plant health and productivity 140 . Thus, the long-term or chronic effects of these NPs are critical in terms of their use in agriculture.…”
