“…In EAR, predicted actin-101 (spot 4404) and predicted tubulin beta-3 chain-like (spot 2602) were up-regulated. A similar result was reported in a study on sunflowers where an interaction among endogenous nitric oxide, actin, and IAA at specific stages (in the initiation and extension phase) of adventitious root formation was observed (Yadav et al 2011). Research on Medicago sativa (L.) ankyrin-protein kinases show that MsAPK1 could only phosphorylate tubulin and Arabidopsis thaliana (L.) MsAPK gene assays revealed that APK-mediated signaling may link the perception of external abiotic signals and the microtubule cytoskeleton and influence adventitious root development (Chinchilla et al 2008).…”

Key message Comparative proteome analysis revealed the proteins that are differentially expressed during the processes of tetraploid black locust (Robinia pseudoacacia L.) adventitious root formation, which are involved in carbohydrate binding, energy and metabolism, and stress response. Abstract The tetraploid black locust (Robinia pseudoacacia L.) is an important fast-growing tree used in afforestation and is also a protein-rich feed for poultry. Currently, the primary approach for tetraploid black locust reproduction is through cutting propagation. To identify the specific proteins in the rooting process, including the formation of adventitious root primordium (ARP) and the elongation of adventitious root (EAR), a comparative proteomic analysis of the ARP and EAR of tetraploid black locust was performed to identify related proteins that may be involved in regulating ARP formation and the process of EAR. High-resolution two-dimensional electrophoresis (2-DE) followed by colloidal Coomassie staining and mass spectrometric (MS) analysis was used to identify differentially expressed proteins in ARP and EAR. A total of 84 protein spots showed significant expression changes by 2-DE and were successfully identified by MALDI TOF/ TOF MS/MS. Of these, 29 proteins were differentially expressed during the ARP phase, and the remaining 55 proteins did so in the EAR phase. The majority of identified proteins were classified into functional categories, including carbohydrate binding, energy and metabolism, protein degradation/folding and import, cellular cytoskeleton, hormonerelated and oxidation reactions, stress response, cell proliferation, and transcription regulation. Quantitative real-time PCR analysis was performed for selected proteins and showed that not all of the protein expression levels were consistent with the mRNA levels. This study provides the basis for further functional studies of differentially expressed proteins, which will contribute to the understanding of the biochemical processes in adventitious root primordium formation and the elongation of adventitious root.

“…Both NO and ROS form 8‐nitro‐cGMP inducing stomata closure (Joudoi et al ., ). Similar to ABA, auxin can also induce ROS and NO synthesis, and both can act on auxin‐mediated signaling (Yadav et al ., ; Farnese et al ., ; ). Shi et al .…”

Reactive oxygen species, abiotic stress and stress combination

Reactive oxygen species (ROS) play a key role in the acclimation process of plants to abiotic stress. They primarily function as signal transduction molecules that regulate different pathways during plant acclimation to stress, but are also toxic byproducts of stress metabolism. Because each subcellular compartment in plants contains its own set of ROS-producing and ROS-scavenging pathways, the steady-state level of ROS, as well as the redox state of each compartment, is different at any given time giving rise to a distinct signature of ROS levels at the different compartments of the cell. Here we review recent studies on the role of ROS in abiotic stress in plants, and propose that different abiotic stresses, such as drought, heat, salinity and high light, result in different ROS signatures that determine the specificity of the acclimation response and help tailor it to the exact stress the plant encounters. We further address the role of ROS in the acclimation of plants to stress combination as well as the role of ROS in mediating rapid systemic signaling during abiotic stress. We conclude that as long as cells maintain high enough energy reserves to detoxify ROS, ROS is beneficial to plants during abiotic stress enabling them to adjust their metabolism and mount a proper acclimation response.

“…Recently, an increasing number of articles have reported the effects of exogenous NO on alleviating HM toxicity in various plants (Jin et al 2010;Xiong et al 2010;Panda et al 2011). Evidence has been obtained for the relation of NO and plant growth regulators (Palavan-Unsal & Arisan 2009;Yadav et al 2011;Shen et al 2013). However, there are not any studies that have identified the effects of TRIA and NO on stress-induced changes in the antioxidative defense system in plants under HM stresses.…”

In this study, triacontanol (TRIA) and nitric oxide (NO) interaction on arsenic (As)-induced oxidative stress tolerance in coriander (Coriandrum sativum L.) plants was investigated. The results showed that As had a significant adverse effect on the plant's biomass. The seedlings pretreated with TRIA and NO significantly increased growth reduction induced by the metalloid. The obtained results indicated that the application of TRIA and sodium nitroprusside (SNP) generally reduced oxidative markers such as of electrolyte leakage percentage, malondialdehyde and H 2 O 2 contents under As toxicity, while application of As treatment without TRIA + SNP increased these oxidative parameters compared to the control. The non-enzymatic antioxidant contents such as total phenol, anthocyanin, carotenoid, ascorbic acid and reduced glutathione (GSH) were extracted and assayed from both control and treated plants. It was found that TRIA + SNP treatments have a profound effect on the antioxidant metabolism and caused an enhancement in non-enzymatic antioxidant potentials under As toxicity in coriander. Moreover, the results revealed a mutually amplifying reaction between TRIA and NO in reducing As-induced damages.ARTICLE HISTORY
