“…Concerning the abiotic stresses, they include salinity, drought, heavy metals, flooding, chilling, freezing, heat, ozone and ultraviolet radiation. Whereas, the biotic stress includes different pathogens like bacteria, virus, fungi, etc (Abiri et al 2017;Calanca 2017;Lu et al 2017;. Therefore, NANOMATERIALS AND PLANT ABIOTIC STRESS IN AGROECOSYSTEMS crucial important investigations are needed to know how abiotic stresses affect plant growth and its development at different levels including the physiological, biochemical and molecular studies (Cramer et al 2011;Hasanuzzaman et al 2013;Wani et al 2016).…”

“…Ethylene is another hormone essential for plant growth and development playing a crucial role in responses to environmental stress such as pathogen attack, wounding, flooding, high temperatures, and drought (Abiri et al 2017). GhNAC4 promoter showed the presence of four binding sites for ethylene insensitive (EIN) TF, and the ethylene treatment upregulated the transcript levels of GhNAC4.…”

We have studied the expression of GhNAC4, a NAC domain-containing transcription factor from Gossypium hirsutum. The expression of GhNAC4 was upregulated by ABA, cytokinin, JA, GA, auxin, and ethylene. Its expression was also highly induced by drought, osmotic stress, oxidative stress, salinity, high and low-temperature stress, and wounding. To corroborate these observations, we isolated the promoter of GhNAC4 and fused it transcriptionally with uidA (GUS) gene for analyzing its patterns of expression in transgenic tobacco. The Promoter-GUS fusion was also induced by various phytohormones and environmental stresses. The spatio-temporal analysis of the promoter of the GhNAC4 gene revealed that GUS expression was mostly localized to the vascular bundles along with shoot apical meristem and guard cells. We also observed intense staining in other cells upon wounding. A sequence analysis of the promoter revealed the presence of several motifs pertaining to phytohormone responsiveness, stress-inducibility, light and sugar-responsiveness and tissue-specificity. These data were corroborated by a detailed bioinformatic analysis of the promoter sequence of GhNAC4 for identifying the conserved sequences that are associated with the expression of genes in a spatio-temporal or inducive manner. All these data suggests that GhNAC4 is a vascular tissue localizing NAC transcription factor, which might act as a node integrating environmental stress signals for modulating plant growth and development with the aid of phytohormonal stimuli.Key messageGhNAC4 transcription factor from cotton localizes to vascular bundles and is highly upregulated by phytohormones and environmental stresses.

“…Ethylene is a phytohormone that performs diverse regulatory functions in the growth and development of plants, including seed germination [11,12] root growth [13,14] fruit ripening [15,16], and flower and leaf abscission [17,18]. Additionally, ethylene plays a key role in biotic and abiotic stress responses [19][20][21] and is considered an important modulator of plant growth and development. However, stress conditions elicit increased levels of ACC synthase, which in turn increases the amount of substrate ACC available to produce higher amount of ethylene in plant tissues.…”

Profiling of ACC synthase gene (ACS11) expression in Arabidopsis induced by abiotic stresses

Abiotic stress induce the production of 1-aminocyclopropane-1-carboxylate (ACC), the precursor of ethylene by activating the enzyme ACC synthase. There are twelve ACC synthase genes reported in the genome of Arabidopsis, and the ACC synthase 11 (ACS11) gene encodes a polypeptide that is functional; however, its involvement in ethylene biosynthesis in response to abiotic stresses remains unclear. We evaluated the effects of higher ACC accumulation on A. thaliana seedlings in response to abiotic stressors such as flooding, salinity, cold, and drought. Transgenic plants were generated with ACS11 (ACS11-OX), and they demonstrated that overexpression of ACS11 reduces both root and shoot length observed in seedlings. RT-PCR analysis revealed that abiotic stressors induce the expression of the wild type ACS11 gene. Histochemical staining revealed that GUS activity followed the same time course as induction of wild type ACS11 gene expression, increased ACC levels, and production of stress hormone, ethylene. One finding showed that although induction of wild type ACS11 gene occurs under drought stress, GUS activity was highest at 6 h of drought stress and decreased to levels similar to control seedlings at 12 and 24 h. Thus, Wild type ACS11 expression is involved in ACC production, and abiotic stressors induce the expression of ACS11 gene. Moreover, ACC increases in response to abiotic stress lead to the production of ethylene. All of the data presented here suggest that the overexpression of ACS11 paves the way for the production of stress hormone, ethylene, which adversely affected the growth and development of the plant. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
