Title
Signal transduction during defense response and source-sink transition in tomato
Markus Hofmann Online Publication Service of Würzburg University (Würzburg University) 2003
Other claims from this paper (10)
- Observation Different subsets of MAP kinases are activated depending on the stimulus.
- Observation LpWIPK was identified as the major MAP kinase activity induced after stimulation of tomato cells with different elicitors.
- Mechanism LpWIPK is considered a key regulator of defense response together with sink induction in tomato.
- Mechanism Regulation of photosynthesis is not directly coupled to the MAP kinase signal transduction pathway, since it is independent of MAP kinase activation.
- Observation The newly found heat-activated MAP kinase specifically recognises the heat stress transcription factor HsfA3 as a substrate.
- Observation In Chenopodium rubrum cells, cytosolic changes in pH do not precede the regulation of the marker genes INV and PAL.
- Observation The elicitor-responsive WRKY transcription factor LpWRKY1 was cloned from tomato.
- Observation LpWRKY1 is transiently induced upon pathogen attack and the induction is dependent on phosphorylation.
- Observation LpWRKY1 is phosphorylated in vivo, shown for the first time for WRKY transcription factors.
- Observation Two protein kinases are transiently activated during the defense response to phosphorylate LpWRKY1.
