TGA2 dual activity: N-terminus regulation of reversible DNA binding influenced by NPRI and CK2
TGA2 is a dual-function Systemic Acquired Resistance (SAR) transcription factor involved in the activation and repression of pathogenesis-related (PR) genes. Recent studies have shown that TGA2 is able to switch from a basal repressor to activator, likely, through regulatory control from its …

The Molecular Consequences of CK2-mediated Phosphorylation of the TGA2 Transcription Factor within Systemic Acquired Resistance of Arabidopsis thaliana
… TGA II-clade transcription factors (namely TGA2) repress PR1 activity prior to infection by forming large oligomeric complexes effectively blocking gene transcription. After pathogen detection, these complexes are dispersed by a mechanism unknown until now and free TGA molecules interact …

The GRAS Protein SCL14 and TGA Transcription Factors Interact to Regulate Stress-Inducible Promoters
… von TGA-Transkriptionsfaktoren der Klasse II (TGA2, TGA5 und TGA6) identifiziert. In Hefe aktiviert SCL14 die Transkription eines Reporter-Gens nach Interaktion mit TGA2. Fehlt TGA2, findet auch keine Aktivierung statt, was zeigt, dass SCL14 von sich aus nicht an DNA binden kann sondern von …

Die Bedeutung des Proteins Scarecrow-like 14 in der Regulation der Transkription von Stressgenen
… so zu einer Aktivierung der Genexpression. Für TGA2.2 aus Tabak konnte in Hefe gezeigt werden, dass er an DNA bindet, aber keine Aktivierung der Genexpression bewirkt. In einem modifizierten Hefe Einhybridsystem mit dem orthologen Faktor TGA2 aus Arabidopsis thaliana konnte Scarecrow-like 14 …

Vias de sinalização mediadas por ácido salicílico e metil-jasmonato e papel de GmbZIP89 em resposta à infecção por Phakopsora pachyrhizi em genótipos contrastantes de soja
… ocorre a indução de resposta via JA. Supomos que TGA2 e ORA59 estejam envolvidos no crosstalk JA/SA durante a infecção. SA pode induzir a expressão de TGA2 e inibir a expressão de ORA59 comprometendo a indução de genes responsivos a JA. Mostramos que nos estágios iniciais e tardios de infecção, P. …

Regulation of the Cytochrome P450 Gene, CYP81D11, in Arabidopsis thaliana, Subjected to Chemical Stress
… von Klasse II TGA Transkriptionsfaktoren (TGA2, 5 und 6) und dem TGA interagierenden GRAS Protein SCARECROW-LIKE14. Für das TGA2,5,6/SCL14-aktiverte Cytochrom P450 Gen CYP81D11 wurde in zahlreichen Microarray-Analysen gezeigt, dass es stark aktivierbar ist durch verschiedene reaktive …
