Nanomaterial-induced modulation of hormonal pathways enhances plant cell growth

Abstract

In this study, Bright Yellow 2 (BY-2) tobacco (Nicotiana tabacum L.) cell suspensions exposed to manganese ferrite nanoparticles (nMnFe2O4) or nitrogen-doped carbon dots (N-CDs) were analyzed for hormonal pathways. The...

Nickel Oxide Nanoparticles Improve Soybean Yield and Enhance Nitrogen Assimilation

“…The regulation of plant hormones by NPs is a dynamic and rather complex process, the mechanisms of which remain unclear. One of the mechanisms that have been reported is that the expression of hormone synthesis-related genes and hormone pathways may be regulated by NPs. , Therefore, further studies are required in the future.…”

Cerium oxide nanomaterials improve cucumber flowering, fruit yield and quality: the rhizosphere effect

“…19 Recently, nanomaterials (NMs) have been reported as growth regulators, which can not only stimulate the synthesis of IAA in plant cells but also promote the secretion of IAA by microorganisms to facilitate their colonization in roots. 20,21 Cerium oxide (CeO 2 ) NMs are among the priority NMs selected by the Working Group of Manufactured Nanomaterials of the Organization for Economic Cooperation and Development because of their unique physicochemical properties, 22 which make them ideal for a range of agricultural applications. Although the inhibitory effect of CeO 2 NMs on crop growth has been reported, 23,24 recent studies have shown that low concentrations of CeO 2 NMs could increase crop yield and quality, mostly by improving photosynthesis, increasing antioxidant capacity and nutrient acquisition, inducing various metabolic pathways, and altering rhizosphere microorganisms.…”

Earthworms Drive the Effect of La2O3 Nanoparticles on Radish Taproot Metabolite Profiles and Rhizosphere Microbial Communities

“…30 IAA is the most abundant auxin and the major regulator for controlling plant cell division and expansion. 31,32 Here, we found that the IAA content in leaves and taproot flesh tissues was significantly negatively correlated with the La bioavailability and accumulation in soils and plant tissues (Figure S3). The La 2 O 3 NP exposure without and with earthworms notably reduced the IAA content in the leaves by 45.7 and 43.3%, respectively (Figure 3A), and significantly decreased the IAA content in the taproot flesh tissues by 24.8 and 27.8%, respectively (Figure 3B).…”
