“…It is possible that the observed branching patterns also reflect assortment based on functional as well as phylogenetic grounds. However, among those catalases in the solanaceous cluster, termed class I1 catalases by Willekens et al (1994a), there are differences in expression patterns with respect to SA inducibility (Chen and Klessig, 1991;Chen et al, 1993;Willekens et al, 199413;Niebel et al, 1995). To date, four catalase genes, Arabidopsis CAT2 (Zhong et al, 1994) and CAT3 (Zhong and McClung, 1996), maize CaU (Redinbaugh et al, 1990;Boldt and Scandalios, 1995), and N .…”

Catalase Is Encoded by a Multigene Family in Arabidopsis thaliana (L.) Heynh

The catalase multigene family in Arabidopsis includes three genes encoding individual subunits that associate to form at least six isozymes that are readily resolved by nondenaturing gel electrophoresis. CATl and CAT3map to chromosome 1 , and CAT2maps to chromosome 4. The nucleotide sequences of the three coding regions are 70 to 72% identical. The amino acid sequences of the three catalase subunits are 75 to 84% identical and 87 to 94% similar, considering conservative substitutions. Both the individual isozymes and the individual subunit mRNAs show distinct patterns of spatial (organ-specific) expression. Six isozymes are detected in flowers and leaves and two are seen in roots. Similarly, mRNA abundance of the three genes varies among organs. All three mRNAs are highly expressed in bolts, and CAT2 and CAT3 are highly expressed in leaves.

“…Treatment of maize during late embryogenesis with SA induces scutellar accumulation of Cat2 transcript and CAT-2 isozyme protein (Guan and Scandalios, 1995). Application of SA to Solanum tuberosum induces Caf2St (Niebel et al, 1995). However, the characterized catalase genes of Nicotiana plumbaginifolia are not induced by SA (Willekens et al, 1994b).…”

“…This fact suggests that Erwinia is capable of suppressing the SAmediated SAR response of plants in the early stages of the plant-pathogen interaction. It has recently been shown that Erwinia carotovora induces the local and systemic expression of a gene encoding a catalase in potato plants (Niebel et al, 1995). A tobacco catalase (SABP) has been proposed to function as a receptor of SA in the signal transduction pathway leading to SAR (Chen et aL, 1993).…”

“…One possibility is that the Erwinia CF inhibition of the SA pathway is due to induction of a gene encoding a catalase. This could result in reduction of the levels of active oxygen species that could act as secondary messengers for defense-related gene activation and SAR, thus allowing the establishment of a compatible interaction (Niebel et al, 1995). Nevertheless, it has also been suggested that hydrogen peroxide would act upstream of SA and is therefore not a secondary messenger of SA (Bi et aL, 1995;Neuenschwander et aL, 1995).…”

Salicylic acid and the plant pathogen Erwinia carotovora induce defense genes via antagonistic pathways

et al. 1997

SummaryInfection of tobacco plants with the plant pathogenic bacterium Erwinia carotovora subsp, carotovora or treatment of plants with Erwinia-derived elicitor preparations leads to the induction of a number of genes thought to play a role in plant defense response to pathogens. In order to determine the role of salicylic acid (SA) in the induction of the Erwinia responsive genes, the accumulation of mRNAs for these and other genes encoding pathogenesis-related proteins (PR genes) in response to both Erwinia elicitors and SA was determined. PR genes were identified which were preferentially induced by Erwinia elicitor preparations, one gene was induced by SA but not by Erwinia, and another gene was induced by both type of treatments. The differential expression of these genes and the timing of induction suggest that SA is not the signal molecule leading to the early response of plants to Erwinia. This was demonstrated by experiments using transgenic NahG plants that overproduce a salicylate hydroxylase inactivating SA. The elicitation of PR genes by Erwinia was similar in NahG and wild-type plants. Therefore, induction of plant defense genes by Erwinia and SA seems to be by two distinct pathways leading to expression of separate sets of genes. Furthermore, we could demonstrate that Erwinia elicitors antagonize the SA-mediated induction of PR genes. Similarly, SA appeared to inhibit the induction of PR genes elicited by Erwinia. The observed antagonism between the two signal transduction pathways indicates the presence of a common regulatory element in both pathways that acts downstream of SA in the SA-mediated response.

“…Higher expression of CAT 2 mRNA in roots of potato was found during pathogenesis of Corynebacterium sepedonicum NCPPB 2137 and Erwinia cartovora spp. cartovora NCPPB 312 and provide the first evidence that class II CAT isoforms are also pathogen induced (Niebel et al, 1995). Thus the elevated CAT activity in grapefruit partially explains the decline in H 2 O 2 concentrations in grapefruit.…”
