“…In plant genome, a large number of transcription factors play Positive numbers in fold change are upregulated and negative numbers are downregulated. key roles in the biotic or abiotic stress response (Eulgem et al 2000;Dong et al 2003;Fujita et al 2006;Sakuma et al 2006;Alves et al 2013;Li et al 2014). In our study, the expression levels of 108 upregulated TF genes and 93 downregulated TF genes changed more than 2-fold (P < 0.05) under low potassium stress (table 3).…”

“…Under unfavourable conditions, TFs such as WRKY, MYB, ERF, bZIP and NAC are induced and cause gene expression that protects plants from damage caused by stress . Previous studies have shown that many TFs are induced under abiotic stresses including drought, salt, temperature, metal and light (Soo 2006;Rushton et al 2010;Mizoi et al 2012;Nakashima et al 2012;Li et al 2014). However, only a few TFs respond to mineral starvation.…”

Potassium plays a key role in plant development and reproduction. In agricultural practice, potassium deficiency is common worldwide, and leads to crop growth inhibition and output reduction. In this study, we analysed the transcriptome of tobacco seedlings under low potassium stress. Tobacco seedlings with or without decreased potassium treatment were harvested after 0 (control), 6, 12, or 24 h and were submitted for microarray analysis. The results showed that up to 3790 genes were upregulated or downregulated more than 2-fold as a result of the decreased potassium treatment. Gene ontology analysis revealed significantly differentially expressed genes that were categorized as cation binding, transcription regulation, metabolic processes, transporter activity and enzyme regulation. Some potassium, nitrogen and phosphorus transporters; transcription factors; and plant signal molecules, such as CPKs were also significantly differentially expressed under potassium deficiency. Our results indicate that the expression profiles of a large number of genes involved in various plant physiological processes are significantly altered in response to potassium deficiency, which can result in physiological and morphological changes in tobacco plants.

“…Additionally, it can cause a series of physiological and biochemical changes in plants (Wu et al 2014;Li et al 2015;Zhang 2015). To cope with the challenging aspects of drought, plants use several mechanisms and produce response at physiological and molecular levels (Shiriga et al 2014).…”

MicroRNAs (miRNAs) are a class of small non-coding regulatory RNAs that regulate gene expression by guiding target mRNA cleavage or translational inhibition. Drought is a common environmental stress influencing crop growth and development. To date, it has been reported that a number of plant miRNA are involved in drought stress response. In this study, we comparatively investigated drought stress-responsive miRNAs in the root and leaf of bread wheat (Triticum aestivum cv. Sivas 111/33) by miRNA microarray screening. miRNA microarray analysis showed that 285 miRNAs (207 upregulated and 78 downregulated) and 244 miRNAs (115 upregulated and 129 downregulated) were differentially expressed in leaf and root tissues, respectively. Among the differentially expressed miRNAs, 23 miRNAs were only expressed in the leaf and 26 miRNAs were only expressed in the root of wheat growth under drought stress. Upon drought treatment, expression of miR159, miR160, miR166, miR169, miR172, miR395, miR396, miR408, miR472, miR477, miR482, miR1858, miR2118, and miR5049 were found to be significantly differentiated in bread wheat. The regulatory network analysis showed that miR395 has connections with a number of target transcripts, and miR159 and miR319 share a number of target genes. Drought-tolerant and drought-sensitive wheat cultivars showed altered expression pattern upon drought stress in terms of investigated miRNA and their target transcript expression level.

“…A number of TF families, notably AP2/DREB, MYB, WRKY and NAC (NAM, ATAF1, 2 and CUC2), have been implicated in regulating the plant response to abiotic stress and in modulating growth and development [5][6][7][8][9][10][11][12][13]. The NAC TF family is one of the largest families of plant-specific TFs.…”
