“…When exposed to salt stress, many species of plants usually respond with activation of diverse signal transduction pathways to resist salt damage (Wang et al , Shi et al , Wu et al ). In this study, we identified a TCTP (spot 11), involved in target of rapamycin signaling pathway, that increased by both AHL and NaCl + AHL treatments.…”

To evaluate the alleviating action of exogenous N-acyl-homoserine lactones (AHLs) on NaCl toxicity, morphological, physiological and proteomic changes were investigated in Arabidopsis thaliana seedlings. Salinity stress decreased growth parameters, increased malondialdehyde (MDA) contents and antioxidant enzymes such as superoxide dismutase (SOD), guaiacol peroxidase (POD) and catalase activities. Application of lower concentration of AHL had a relieving effect on Arabidopsis seedlings under salinity stress which dramatically decreased MDA content, and increased growth parameters as well as SOD and POD activities. Total proteins were extracted from the control, NaCl-, AHL- and NaCl + AHL-treated seedlings and were separated using two-dimensional gel electrophoresis. A total of 127 protein spots showed different expression compared with the control. Mass spectrometry analysis allowed the identification of 97 proteins involved in multiple pathways, i.e. defense/stress/detoxification, photosynthesis, protein metabolism, signal transduction, transcription, cell wall biogenesis, metabolisms of carbon, lipid, energy, sulfur, nucleotide and sugar. These results suggest that defense/stress response, metabolism and energy, signal transduction and regulation, protein metabolism and transcription-related proteins may be particularly subjected to regulation in salt stressed Arabidopsis seedlings, when treated with AHL and that this regulation lead to improved salt tolerance and plant growth. Overall, this study provides insight to the effect of AHL on salinity stress for the first time, and also sheds light on overview of the molecular mechanism of AHL-regulated plant growth promotion and salt resistance.

“…OsMAPKK1 is a known regulator of the salt stress response, and its expression is induced by high salt. 11 OsMAPKK6, on the other hand, is involved in salt and chilling stress tolerance. 12,13 These observations, together with its stress induction pattern (Figure 1a), imply that OsMAPKKK63 function might be associated with high salt or other stress response.…”

Approximately 75 MAP kinase kinase kinases (MAPKKKs) have been identified in the rice genome. However, only a few of them have been functionally characterized. In this paper, we report the function of a rice MAPKKK, OsMAPKKK63. OsMAPKKK63 was found to be induced by several abiotic stresses, including high salinity, chilling and drought. Our data indicate that OsMAPKKK63 possesses in vitro kinase activity and that it interacts with rice MAP kinase kinase OsMKK1 and OsMKK6. The two rice MKKs are known mediator of the salt stress response, implying that OsMAPKKK63 may be involved in the high salinity response. Our analysis of an OsMAPKKK63 knockout mutant indeed demonstrated that it is necessary for normal response to high salt. On the other hand, OsMAPKKK63 OX lines exhibited viviparous phenotype in both rice and Arabidopsis. The result suggests that OsMAPKKK63 may also be involved in seed dormancy control. ARTICLE HISTORY

“…We could speculate that some miRNAs in H. caspica might have the potential for responding to high salt stress at other time points not 48 h. And, by KEGG analysis, the some targets of miRNAs in H. caspica were mapped to relative salt stress pathways. We chose nine possible pathways (calcium signalling pathway, MAPK signalling pathway, plant hormone signal transduction, flavonoid biosynthesis, ubiquitin‐mediated proteolysis, apoptosis, ABC transporter, peroxisome and DNA repair) (Cheng et al ., ; Guan et al ., ; Kim et al ., ; Wang et al ., ) associated with salt stress to do further analysis. Our results showed that 15 miRNAs were associated with these pathways (Figure ).…”

SummaryMicroRNAs (miRNAs), an extensive class of small regulatory RNAs, play versatile roles in plant growth and development as well as stress responses. However, the regulatory mechanism is unclear on miRNA-mediated response to abiotic stress in plants. Halostachys caspica is a halophytic plant species and a great model for investigating plant response to salinity stress. However, no research has been performed on miRNAs in H. caspica. In this study, we employed deep sequencing to identify both conserved and novel miRNAs from salinity-exposed H. caspica and its untreated control. Among the 13-19 million sequences generated from both treatments, a total of 170 conserved miRNAs, belonging to 151 miRNA families, were identified; among these miRNAs, 31 were significantly up-regulated and 48 were significantly down-regulated by salinity stress. We also identified 102 novel miRNAs from H. caspica; among them, 12 miRNAs were significantly up-regulated and 13 were significantly down-regulated by salinity. qRT-PCR expression analysis validated the deep sequencing results and also demonstrated that miRNAs and their targeted genes were responsive to high salt stress and existed a negative expression correlation between miRNAs and their targets. miRNA-target prediction, GO and KEGG analysis showed that miRNAs were involved in salt stress-related biological pathway, including calcium signalling pathway, MAPK signalling pathway, plant hormone signal transduction and flavonoid biosynthesis, etc. This suggests that miRNAs play an important role in plant salt stress tolerance in H. caspica. This result could be used to improve salt tolerance in crops and woods.
