“…This contribution about the transcriptional regulation of the terpenoid indole alkaloid (TIA) pathway in Catharanthus roseus is an update of previous reviews (Meijer et al 1993a;Memelink et al 2001a, b;Hilliou et al 2001;Gantet and Memelink 2002;Vom Endt et al 2002;Pauw and Memelink 2005).…”

“…Whether CrMYC1 has an effect on STR gene expression has not been tested. Interestingly, G-box and G-box-like elements were found to be essential for the JA-responsiveness of several promoters (Pauw and Memelink 2005). In Arabidopsis, the bHLH transcription factor AtMYC2 (also called JIN1 or RAP-1), which binds to the G-box (de Pater et al 1997), regulates the expression of certain JA-responsive genes (Lorenzo et al 2004;Boter et al 2004).…”

Plants produce alkaloids, among others, to protect themselves against microbial infection, herbivore attack or ultraviolet irradiation. For man, alkaloid metabolism is the source of many natural products with useful applications, including pharmaceuticals. A major mechanism regulating alkaloid production in plant cells is the control of the transcription of the biosynthetic genes. Several transcription factors involved in the regulation of alkaloid biosynthesis genes have been isolated and studied. There are indications that the abundance and activities of transcription factors themselves are regulated by external signals. The aim of this review is to give an update on the transcriptional regulation of terpenoid indole metabolism in Catharanthus roseus.

“…They are known to regulate a number of different physiological processes in plants including the induction of senescence, vegetative storage proteins, and proteinase inhibitors (Koda 1992). They also have a role in interplant signalling (Pena-Cortes et al 2004) and in signal transduction in relation to defence gene induction (Pauw and Memelink 2004;Pozo et al 2004). Endogenous JA concentrations increased between 21 and 35 days after inoculation in infected B. rapa roots (Grsic et al 1999) indicating a role for JA as a signal during clubroot development.…”

What can we learn from clubroots: alterations in host roots and hormone homeostasis caused by Plasmodiophora brassicae

The clubroot disease of cruciferous crops is caused by an obligate biotrophic protist, Plasmodiophora brassicae. The disease is characterized by the development of large root galls accompanied by changes in source-sink relations and the hormonal balance within the plant. Since the disease is difficult to control, it is of high economic interest to understand the events leading to gall formation. In this review we will give an overview on the current knowledge of changes brought about in the host root by this obligate biotrophic pathogen. Emphasis will be on the regulation of changes in plant hormone homeostasis, mainly auxins and cytokinins; the possible role of secondary metabolites, especially indole glucosinolates, in gall formation and auxin homeostasis will be discussed. Also, results from mutant analysis and microarrays using the model plant Arabidopsis thaliana are presented.

“…Transcription factors are believed to play a crucial role in the regulation of downstream gene expression of the cross-talking signal transduction pathways of jasmonate and ethylene (Pauw and Memelink 2005). Ethylene often acts in concert with jasmonate in activating the expression of defense-related genes such as basic chitinase (PR-3), osmotin (PR-5), PR-1b and plant defensin (PDF1.2) (Xu et al 1994;O'Donnell et al 1996;Penninckx et al 1998;Rojo et al 2003;Pauw and Memelink 2005).…”

It has been demonstrated that the jasmonate and ethylene pathways converge at the transcriptional activation of a gene for ethyleneresponse factor 1 (ERF1), which encodes a transcription factor of the ethylene-responsive transcription-factor (ERF) family (Lorenzo et al 2003).…”

Identification of genes of the plant-specific transcription-factor families cooperatively regulated by ethylene and jasmonate in Arabidopsis thaliana

The analysis of expression patterns of transcription-factor genes will be the basis for a better understanding of their biological functions in plants. In this study, we designed and developed an oligo-DNA macroarray consisting of gene-specific probes of 60-65 nucleotides for 288 transcription-factor genes, which cover COL, DOF, ERF, and NAC family genes. To investigate transcription-factor genes that are cooperatively regulated by jasmonate and ethylene in arabidopsis (Arabidopsis thaliana (L.) Heynh.) plants, we analyzed the expression profile of transcription-factor genes using the oligo-DNA macroarray technique in arabidopsis plants treated with methyl jasmonate and 1-aminocyclopropane-1-carboxylic acid. Then, transcript levels of candidate genes-which were selected based on the result of macroarray analysis-were evaluated by the quantitative real-time RT-PCR method. Finally, we identified an ERF family gene that is cooperatively regulated by both hormones, and designated as cooperatively regulated by ethylene and jasmonate 1 (CEJ1).
