“…73 Plants generally respond to abiotic stress by desaturation of membrane lipids, 74 activation of enzymatic and non-enzymatic antioxidant systems, 75 accumulation of compatible solutes 76 and induction of molecular chaperones to mop up free oxygen radicals. 77 These responses are governed by a complicated network consisting of upstream signaling molecules which include stress hormones (e.g. abscisic acid [ABA]), 78 ROS, 79 T A B L E 1 Properties and interactions of C-dots with plants and their impact on plant processes.…”

The productivity of global crop production is under threat caused by various biotic and abiotic adverse conditions, such as plant diseases and pests, which are responsible for 20%–40% of global crop losses estimated at a value of USD 220 billion, and can be further exacerbated by climate change. Agricultural industries are calling for game‐changer technologies to enable productive and sustainable farming. Carbon dots (C‐dots) are carbon‐based nanoparticles, smaller than 50 nm, exhibiting unique opto‐electro‐properties. They have been shown to have positive impact on managing diverse biotic and abiotic stresses faced by the crops. Owing to their versatile carbon chemistry, the surface functionalities of C‐dots can be readily tuned to regulate plant physiological processes. This review is focussed on establishing the correlations between the physiochemical properties of C‐dots and their impacts on plants growth and health. The summary of the literature demonstrates that C‐dots hold great promise in improving plant tolerance to heat, drought, toxic chemicals, and invading pathogens.image

“…Another mechanism for dealing with damaged or misfolded proteins during abiotic stress involves the production of chaperones [138]. Genes encoding chaperones including heat shock proteins (HSP), DnaJ proteins, and late embryogenisis abundant (LEA) proteins are often induced in response to abiotic stresses to deal with protein aggregates, misfolded proteins, and denatured proteins.…”

“…Genes encoding chaperones including heat shock proteins (HSP), DnaJ proteins, and late embryogenisis abundant (LEA) proteins are often induced in response to abiotic stresses to deal with protein aggregates, misfolded proteins, and denatured proteins. Overexpression of various HSPs in Arabidopsis, rice and tobacco conferred increased tolerance, or in some cases increased sensitivity, to abiotic stresses [138]. Dehydrins are present in the developing embryo and also accumulate in plants exposed to salinity and low temperature stress.…”

Drought and heat are two major stresses predicted to increase in the future due to climate change. Plants exposed to multiple stressors elicit unique responses from those observed under individual stresses. A comparative transcriptome analysis of Lolium temulentum exposed to drought plus heat and non-stressed control plants revealed 20,221 unique up-regulated and 17,034 unique down-regulated differentially regulated transcripts. Gene ontology analysis revealed a strong emphasis on transcriptional regulation, protein folding, cell cycle/parts, organelles, binding, transport, signaling, oxidoreductase, and antioxidant activity. Differentially expressed genes (DEGs) encoding for transcriptional control proteins such as basic leucine zipper, APETALA2/Ethylene Responsive Factor, NAC, and WRKY transcription factors, and Zinc Finger (CCCH type and others) proteins were more often up-regulated, while DEGs encoding Basic Helix-Loop-Helix, MYB and GATA transcription factors, and C2H2 type Zinc Finger proteins were more often down-regulated. The DEGs encoding heat shock transcription factors were only up-regulated. Of the hormones, auxin-related DEGs were the most prevalent, encoding for auxin response factors, binding proteins, and efflux/influx carriers. Gibberellin-, cytokinin- and ABA-related DEGs were also prevalent, with fewer DEGs related to jasmonates and brassinosteroids. Knowledge of genes/pathways that grasses use to respond to the combination of heat/drought will be useful in developing multi-stress resistant grasses.

“…They would activate the stress-responsive mechanisms to repair the proteins and membranes damages, protect, and redevise homeostasis [15]. Insufficient responses at several steps within the signaling and gene activation may ultimately result in permanent damages in destruction of functional and cellular homeostasis, leading to cell death, and structural proteins and membranes [16].…”
