“…However, it remains to be determined whether SAPs bind to DNA and regulate transcription directly or whether observed transcriptome changes are the result of activation of some transcription factors by SAPs. Recently, a cotton SAP (GaZnF) has been reported to bind to a MYB‐box element present in the GUSP1 (cotton stress responsive gene) promoter , indicating a possible transcription regulator activity of SAP proteins. Therefore, their activity as direct regulators of transcription also needs attention.…”

Stress associated proteins (SAPs), novel A20/AN1 zinc-finger domain-containing proteins, are fast emerging as potential candidates for biotechnological approaches in order to improve abiotic stress tolerance in plants - the ultimate aim of which is crop-yield protection. Until relatively recently, such proteins had only been identified in humans, where they had been shown to be key regulators of innate immunity. Their phylogenetic relationship and recruitment of diverse protein domains reflect an architectural and mechanistic diversity. Emerging evidence suggests that SAPs may act as ubiquitin ligase, redox sensor, and regulator of gene expression during stress. Here, we evaluate the new knowledge on SAPs with a view to understand their mechanism of action. Furthermore, we set an agenda for investigating hitherto unexplored roles of these proteins.

“…The EST JK757674 exhibited significant similarity with A. thaliana putative homolog (AT5G10370) ortholog AT5G10370 zinc finger (ZF) domain containing protein. ZF are involved in biotic and abiotic stresses (Zahur et al, 2012;Shi et al, 2014, Butt et al, 2017. Zinc finger family members have been shown to play diverse roles in the hormone signal transduction and drought stress response (Kiełbowicz-Matuk, 2012;Baldoni et al, 2015).…”

“…Primers were designed using freely available online software primer 3 ver 4 (http://primer3.ut.ee/) and synthesized using commercial facility (GeneScript, NJ, USA). Cotton Glyceraldehyde 3phosphate dehydrogenase (GAPDH) primers were used as reference genes as mentioned in previous studies (Zahur et al, 2012). In each reaction, 200 ng cDNA of both control and drought stress plants was used for each biological and technical replicate in triplicate.…”

Cotton is major fiber crop among agricultural commodities grown worldwide. Prolonged osmotic stress and seasonal water shortage effect plant growth and yields. To explore the drought responsive molecular mechanism in cotton roots, we constructed cDNA library for the identification, functional annotation and expression analysis of potential drought responsive transcripts. mRNA extracted from cotton roots under drought stress was used to construct cDNA library. A total of 711 expressed sequence tags were generated from cDNA library. NCBI BLAST analysis of reported expressed sequence tags showed homology of 27% sequences with Gossypium species while 24% sequences showed no sequence similarity in non-redundant nucleotide database. Remaining 49% sequences revealed sequence similarity results with other plant species. Functional annotation was performed for sequenced EST's using Arabidopsis Gene ontology database (TAIR). We examined the expression pattern of 08 differentially expressed ESTs using RT-qPCR and validated that all these were upregulated in roots under osmotic stress, but to different folds. The candidate EST sequences identified in this study will be valuable resource to elucidate stress responsive molecular mechanism and genetic breeding of cotton in future.

“…In plants, SAP genes are induced by one or multiple abiotic stresses and function in a stress- and/or tissue-specific manner [ 54 , 56 , 57 , 58 , 59 ]. Recent studies suggest that SAPs act as ubiquitin ligases, redox sensors, and/or gene expression regulators under stress conditions [ 55 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ]. Interestingly, the majority of the studies attempting to constitutively express SAPs in model plants (such as tobacco, Arabidopsis , and rice) report enhanced tolerance to multiple abiotic stress factors, including drought, salinity, cold, heat, oxidative stresses, and heavy metals [ 62 , 67 , 68 , 69 , 70 ].…”

Halophytes are plant species widely distributed in saline habitats, such as beaches, postindustrial wastelands, irrigated lands, salt flats, and others. Excessive salt level, known to limit plant growth, is not harmful to halophytes, which have developed a variety of defense mechanisms allowing them to colonize harsh environments. Plants under stress are known to respond with several morpho-anatomical adaptations, but also to enhance the production of secondary metabolites to better cope with difficult conditions. Owing to these adaptations, halophytes are an interesting group of undemanding plants with a high potential for application in the food and pharmaceutical industries. Therefore, this review aims to present the characteristics of halophytes, describe changes in their gene expression, and discuss their synthesized metabolites of pharmacognostic and pharmacological significance. Lobularia maritima is characterized as a widely spread halophyte that has been shown to exhibit various pharmacological properties in vitro and in vivo. It is concluded that halophytes may become important sources of natural products for the treatment of various ailments and for supplementing the human diet with necessary non-nutrients and minerals. However, extensive studies are needed to deepen the knowledge of their biological potential in vivo, so that they can be introduced to the pharmaceutical and food industries.
