“…Although some influence of NO on the endogenous ABA levels has been reported (Zhao et al, 2001;Xing et al, 2004), most of the available information suggests that this free radical acts as a downstream messenger in the ABA signaling cascades (Garcia-Mata and Lamattina, 2001;Bright et al, 2006;Hao et al, 2008;Song et al, 2008;Tossi et al, 2009). Interestingly, data obtained in this study firmly indicated that NO is also involved in the ABA-induced upregulation of CAM in pineapple, probably acting as a second messenger of this hormone.…”

“…Accumulating evidence has also demonstrated that NO and ABA closely interact during the signaling processes that underpin the induction of plant adaptive responses to environmental stresses such as drought (Zhao et al, 2001;Garcia-Mata and Lamattina, 2002;Xing et al, 2004;Bright et al, 2006;Neill et al, 2008;Hao et al, 2008), salinity (Ruan et al, 2004), temperature (Song et al, 2008), and UV-B radiation (Tossi et al, 2009).

Genotypic, developmental, and environmental factors converge to determine the degree of Crassulacean acid metabolism (CAM) expression. To characterize the signaling events controlling CAM expression in young pineapple (Ananas comosus) plants, this photosynthetic pathway was modulated through manipulations in water availability. Rapid, intense, and completely reversible up-regulation in CAM expression was triggered by water deficit, as indicated by the rise in nocturnal malate accumulation and in the expression and activity of important CAM enzymes. During both up-and down-regulation of CAM, the degree of CAM expression was positively and negatively correlated with the endogenous levels of abscisic acid (ABA) and cytokinins, respectively. When exogenously applied, ABA stimulated and cytokinins repressed the expression of CAM. However, inhibition of water deficit-induced ABA accumulation did not block the up-regulation of CAM, suggesting that a parallel, non-ABA-dependent signaling route was also operating. Moreover, strong evidence revealed that nitric oxide (NO) may fulfill an important role during CAM signaling. Up-regulation of CAM was clearly observed in NO-treated plants, and a conspicuous temporal and spatial correlation was also evident between NO production and CAM expression. Removal of NO from the tissues either by adding NO scavenger or by inhibiting NO production significantly impaired ABA-induced up-regulation of CAM, indicating that NO likely acts as a key downstream component in the ABA-dependent signaling pathway. Finally, tungstate or glutamine inhibition of the NO-generating enzyme nitrate reductase completely blocked NO production during ABA-induced up-regulation of CAM, characterizing this enzyme as responsible for NO synthesis during CAM signaling in pineapple plants.

The effect of osmotic stress on oxidative injury, compatible solutes content and water relations was investigated in two maize cultivars (Zea mays L. cv. Ankora -drought-sensitive and cv. Nova -drought-tolerant). Relative water content in leaves of both cultivars decreased after drought treatment, leaf water loss of sensitive cv. Ankora was higher than that of cv. Nova. The 24 h water stress induced by 0.3M sorbitol (-1.4 MPa) resulted in a damage of cell membranes. Lipid peroxidation rose in all studied organs of cv. Ankora and electrolyte leakage in roots of cv. Ankora was much higher than in cv. Nova. Similarly, proline content increased significantly in all studied organs of cv. Ankora. Content of soluble sugars increased in all studied organs of both cultivars, but the mesocotyl of cv. Nova accumulated the highest amount of sugars. The electrolyte leakage was the highest in the roots of both cultivars. Osmotic stress had deep influence predominantly on the roots of both cultivars. It is apparent that stress impact on the drought-sensitive cv. Ankora was deeper than on the drought-tolerant cv. Nova.

“…Previous studies have demonstrated that water scarcity prompts NO production [85,86], and NO improves the water stress resilience of plants. One of the conceivable components by which NO improves plant resilience to water stress is by the direction of ABA biosynthesis [87]. Be that as it may, it is not certain whether NO incites ABA biosynthesis in BR motioning submerged stress.…”

Brassinosteroids (BRs) are the most important growth hormones which are steroidal in nature play crucially involved in growth and progressions of the plant. In recent years, advancements done in accessibility of biological possessions and approaches led to the most applicable mechanisms involved in BRs de novo synthesis, translocation and signaling pathways. The current researchers are also associated with the flexible roles of BRs. From the previous studies, it was manifest that BRs interaction with salicylic acid, abscisic acid, auxin, gibberellin, ethylene, cytokinin, and jasmonic acid in controlling numerous morphophysiological processes in plants. In this section, an effort is made to understand mysterious development and growth-linked either directly or not directly to BRs signaling and its intra-and interrelations with various phytohormones. This, in sequence, will support emerging extrapolative representations to moderate various valuable qualities in plants and address current encounters in agriculture.
