Expression

Organism Comment Expression
Arabidopsis thaliana a significant reduction in the expression of ICS1 during immune responses is observed in the tcp8 tcp9 double mutant. There is a strong negative regulatory region between -128 and -316 bp, and the binding of repressor(s) to this region may be necessary for suppression of ICS1 expression during plant growth and development, TCP8 can bind at this region, while TCP5, TCP11 and TCP19 appear not to bind to the promoter region. TCP8 specifically binds to the TCP binding site in the ICS1 promoter in vitro and in vivo down
Arabidopsis thaliana isozyme ICS1 expression is positively regulated by TCP family transcription factor AtTCP8, e.g. under pathogen attack of Pseudomonas syringae pv. maculicola ES4326. TCP8/TCP9 positively regulate ICS1 expression with redundancy upon pathogen infection, and TCPs are involved in maintaining ICS1 expression up

General Information

General Information Comment Organism
malfunction significant reduction in the expression of ICS1 during immune responses is observed in the tcp8/tcp9 double mutant Arabidopsis thaliana
metabolism isochorismate synthase 1 is a key enzyme in salicylate biosynthesis in Arabidopsis thaliana. The TCP family transcription factor AtTCP8 is a regulator of isozyme ICS1, it binds to a typical TCP binding site in the ICS1 promoter. Expression patterns of TCP8 and its corresponding gene TCP9 largely overlap with ICS1 under pathogen attack. Strong interactions between TCP8 and SAR deficient 1 (SARD1), WRKY family transcription factor 28 (WRKY28), NAC (NAM/ATAF1, ATAF2/CUC2) family transcription factor 019 (NAC019), as well as among TCP8, TCP9 and TCP20, implying a complex coordinated regulatory mechanism underlying ICS1 expression. There is a strong negative regulatory region between -128 and -316 bp, and the binding of repressor(s) to this region may be necessary for suppression of ICS1 expression during plant growth and development, TCP8 can bind at this region, while TCP5, TCP11 and TCP19 appear not to bind to the promoter region. TCP8 specifically binds to the TCP binding site in the ICS1 promoter in vitro and in vivo. Trans-activation capability of TCP8.
