“…Interestingly, high OsCatB and OsCatC activity was observed in salt-tolerant plants grown under salt stress [178]. A similar result was reported by Wutipraditkul et al [179], who observed an inhibitory effect of OsCatC in response to salt stress.…”

Soil salinity is a serious menace in rice production threatening global food security. Rice responses to salt stress involve a series of biological processes, including antioxidation, osmoregulation or osmoprotection, and ion homeostasis, which are regulated by different genes. Understanding these adaptive mechanisms and the key genes involved are crucial in developing highly salt-tolerant cultivars. In this review, we discuss the molecular mechanisms of salt tolerance in rice—from sensing to transcriptional regulation of key genes—based on the current knowledge. Furthermore, we highlight the functionally validated salt-responsive genes in rice.

“…In support, Rao et al (1997) found that SA treatment in A. thaliana elevated the H 2 O 2 content and H 2 O 2 -metabolizing enzymes depended upon the dose of SA concentration and time-duration [ 50 ]. In plants, the various CAT present multiple isoforms with different activities in diverse plant organs [ 53 , 54 , 55 ]. CAT isozymes of chickpea plant were sensitive to SA differently, because SA was a specific inhibitor of CAT activity both in shoot and root [ 56 ].…”

Induced resistance by elicitors is considered to be an eco-friendly strategy to stimulate plant defense against pathogen attack. In this study, we elucidated the effect of salicylic acid (SA) on induced resistance in rubber tree against Phytophthora palmivora and evaluated the possible defense mechanisms that were involved. For SA pretreatment, rubber tree exhibited a significant reduction in disease severity by 41%. Consistent with the occurrence of induced resistance, the pronounced increase in H2O2 level, catalase (CAT) and peroxidase (POD) activities were observed. For defense reactions, exogenous SA promoted the increases of H2O2, CAT, POD and phenylalanine ammonia lyase (PAL) activities, including lignin, endogenous SA and scopoletin (Scp) contents. However, SA had different effects on the activity of each CAT isoform in the particular rubber tree organs. Besides, three partial cDNAs encoding CAT (HbCAT1, HbCAT2 and HbCAT3) and a partial cDNA encoding PAL (HbPAL) were isolated from rubber tree. Moreover, the expressions of HbCAT1, HbPAL and HbPR1 were induced by SA. Our findings suggested that, upon SA priming, the elevated H2O2, CAT, POD and PAL activities, lignin, endogenous SA and Scp contents, including the up-regulated HbCAT1, HbPAL and HbPR1 expressions could potentiate the resistance in rubber tree against P. palmivora.

“…AtCAT1 played an important role in all stresses, AtCAT2 was upregulated by drought and cold, and AtCAT3 was mainly upregulated by oxidative and ABA treatments. Three cDNA sequences of the CAT genes of O. sativa , OsCatA , OsCatB , and OsCatC , were cloned and exhibited variable activity in the presence of different salt stresses (i.e., NaCl, potassium chloride, lithium chloride, and magnesium chloride) at different concentrations (0–1000 mM), with OsCatC showing higher tolerance than OsCatA and OsCatB (<60 mM), whereas the opposite effects were observed when salt concentrations were >125 mM [ 37 ]. The differential expression of ScCAT2 and ScCAT1 in response to various stresses suggests that ScCAT2 and ScCAT1 may coordinately regulate plant development.…”

Catalases, which consist of multiple structural isoforms, catalyze the decomposition of hydrogen peroxide in cells to prevent membrane lipid peroxidation. In this study, a group II catalase gene ScCAT2 (GenBank Accession No. KF528830) was isolated from sugarcane genotype Yacheng05-179. ScCAT2 encoded a predicted protein of 493 amino acid residues, including a catalase active site signature (FARERIPERVVHARGAS) and a heme-ligand signature (RVFAYADTQ). Subcellular localization experiments showed that the ScCAT2 protein was distributed in the cytoplasm, plasma membrane, and nucleus of Nicotiana benthamiana epidermal cells. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis indicated that the ScCAT2 gene was ubiquitously expressed in sugarcane tissues, with expression levels from high to low in stem skin, stem pith, roots, buds, and leaves. ScCAT2 mRNA expression was upregulated after treatment with abscisic acid (ABA), sodium chloride (NaCl), polyethylene glycol (PEG), and 4 °C low temperature, but downregulated by salicylic acid (SA), methyl jasmonate (MeJA), and copper chloride (CuCl2). Moreover, tolerance of Escherichia coli Rosetta cells carrying pET-32a-ScCAT2 was enhanced by NaCl stress, but not by CuCl2 stress. Sporisorium scitamineum infection of 10 different sugarcane genotypes showed that except for YZ03-258, FN40, and FN39, ScCAT2 transcript abundance in four smut-resistant cultivars (Yacheng05-179, YZ01-1413, YT96-86, and LC05-136) significantly increased at the early stage (1 day post-inoculation), and was decreased or did not change in the two smut-medium-susceptibility cultivars (ROC22 and GT02-467), and one smut-susceptible cultivar (YZ03-103) from 0 to 3 dpi. Meanwhile, the N. benthamiana leaves that transiently overexpressed ScCAT2 exhibited less severe disease symptoms, more intense 3,3′-diaminobenzidine (DAB) staining, and higher expression levels of tobacco immune-related marker genes than the control after inoculation with tobacco pathogen Ralstonia solanacearum or Fusarium solani var. coeruleum. These results indicate that ScCAT2 plays a positive role in immune responses during plant–pathogen interactions, as well as in salt, drought, and cold stresses.
