“…Regarding the implication of 14-3-3 proteins in mediating stress signaling, a number of studies have demonstrated that they have an important function in plant responses to biotic stresses (Gökirmak et al, 2010). However, although the expression of 14-3-3 genes is induced by several abiotic stresses, including cold (Jarillo et al, 1994), high salt (Xu and Shi, 2006), and drought (Porcel et al, 2006), as well as phosphorous and iron deficiencies (Wang et al, 2002;Cao et al, 2007), evidence for 14-3-3-mediated abiotic stress responses is still very limited (Yan et al, 2004;Campo et al, 2012;Yang et al, 2013;Zhou et al, 2014).…”

In plants, the expression of 14-3-3 genes reacts to various adverse environmental conditions, including cold, high salt, and drought. Although these results suggest that 14-3-3 proteins have the potential to regulate plant responses to abiotic stresses, their role in such responses remains poorly understood. Previously, we showed that the RARE COLD INDUCIBLE 1A (RCI1A) gene encodes the 14-3-3 psi isoform. Here, we present genetic and molecular evidence implicating RCI1A in the response to low temperature. Our results demonstrate that RCI1A functions as a negative regulator of constitutive freezing tolerance and cold acclimation in Arabidopsis thaliana by controlling cold-induced gene expression. Interestingly, this control is partially performed through an ethylene (ET)-dependent pathway involving physical interaction with different ACC SYNTHASE (ACS) isoforms and a decreased ACS stability. We show that, consequently, RCI1A restrains ET biosynthesis, contributing to establish adequate levels of this hormone in Arabidopsis under both standard and low-temperature conditions. We further show that these levels are required to promote proper cold-induced gene expression and freezing tolerance before and after cold acclimation. All these data indicate that RCI1A connects the low-temperature response with ET biosynthesis to modulate constitutive freezing tolerance and cold acclimation in Arabidopsis.

“…The gene-specific expression patterns in response to diverse environmental stimuli imply that the isoform specificity exists in the 14-3-3 gene family in plants (Xu et al 2012;Sun et al 2014;Xu and Shi 2006;Roberts et al 2002;Denison et al 2011). Several studies have provided genetic evidences to show that individual 14-3-3 isoforms have specific functions during plant development (Radwan et al 2012;Mayfield et al 2012;Li et al 2012;Moriuchi et al 2004) and in adaptation to diverse environmental conditions (Xu et al 2012;Sun et al 2014;Yan et al 2004;Manosava et al 2011;Xu et al 2013;Campo et al 2012). Most of the higher plants have more than one PM H ?…”

“…Fungal infection and salt treatment were found to result in up-regulation of ZmGF14-6 in maize plants, whereas drought stress caused down-regulation of this gene. When rice plants with constitutive expression of ZmGF14-6 were generated, they showed increased drought tolerance (Campo et al 2012).…”

“…Furthermore, OsGF14e has been implicated to have a role in disease resistance through negative effects on the induction of plant defense response genes and cell death (Manosalva et al 2011). Although the gene expression of 14-3-3 proteins under various environmental stress has been investigated (Chen et al 2006;Xu and Shi 2006;Manosalva et al 2011;Campo et al 2012;Xu et al 2012a), expression profiling of the rice 14-3-3 gene family in response to As stress has not yet been studied.…”

The intimate association between the arbuscular mycorrhizal fungi and host plants helps the latter in phosphate acquisition in exchange of carbohydrates and in enhanced stress tolerance. Similarly, the ubiquitous 14-3-3 protein family is known to be a major regulator of plant metabolism and stress responses. However, the involvement of mycorrhiza and plant 14-3-3 proteins interaction in plant response to environmental stimuli, such as arsenic (As) stress, is yet unknown. In this study, we analysed the impact of the As stress on the expression profile of 14-3-3 genes in the shoot of mycorrhiza colonized rice (Oryza sativa) plants. Ten day old rice seedlings were kept for 45 days for mycorrhizal colonisation (10 g inoculum per 120 g soilrite) and were then subjected to 12.5 lM arsenate [As(V)] exposure for 1 and 3 days, in hydroponics. Arsenate stress resulted in significant change in expression of 14-3-3 protein genes in non-colonized and mycorrhiza colonized rice plants which indicated As mediated effects on 14-3-3 proteins as well as interactive impact of mycorrhiza colonization. Indeed, mycorrhiza colonization itself induced up-regulation of all 14-3-3 genes in the absence of As stress. The results thus indicate that 14-3-3 proteins might be involved in As stress signalling and the mycorrhiza induced As stress response of the rice plants.
