A study of PAMP-INDUCED SECRETED PEPTIDE LIKE 6 (PIPL6) in regulation of plant immunity
Gjennestad, Ragnhild Sødal (Master thesis, 2021)Planter har utviklet et robust forsvarssystem mot en rekke organismer som kan forårsake sykdom hos planten. Planteimmunforsvaret består av både induserbare og generelt uttrykte forsvarsmekanismer. En av de induserbare ... -
Funksjonelle studier av to antatte peptid-ligander tilhørende IDA-RELATED PEPTIDE-familien i Arabidopsis thaliana (vårskrinneblom)
Viste, Rannveig (Master thesis, 2013)IDA RELATED PEPTIDE (IRP)1 og IRP9, to antatte sekrerte peptider tilhører sammen med IRP10 den utvidede INFLORESCENCE DEFICIENT IN ABSCISSION (IDA)-genfamilien. På grunn av likheter på proteinnivå antas IRP9 å ha en ... -
Generation of Arabidopsis thaliana mutant lines using the CRISPR-Cas technology for reverse genetics studies of a sugar-responsive LRR-RLK1 (At1g74360) gene.
Sustek, Ferenz (Master thesis, 2019)Plants are sessile organisms that are exposed to environmental changes and therefore require highly regulated pathways and mechanisms that allow them to adapt to such changes. Sugars have a central role in coordinating ... -
Molecular investigation of signalling components in sugar sensing and defence in Arabidopsis thaliana
Najafi, Javad (Doctoral thesis at NTNU;2015:264, Doctoral thesis, 2015)As sessile organisms, plants are continually exposed to signals from environmentally adverse conditions and internal developmental cues. Gathering this information, processing it, and generating a proper physiological ... -
PAMP-INDUCED SECRETED PEPTIDE 3 (PIP3) modulates immunity in Arabidopsis thaliana
Najafi, Javad; Brembu, Tore; Vie, Ane Kjersti; Viste, Rannveig; Winge, Per; Somssich, Imre; Bones, Atle M. (Journal article; Peer reviewed, 2019)Small post-translationally modified peptides are important signalling components of plant defence responses against phytopathogens, acting both as positive and negative modulators. PAMP-INDUCED SECRETED PEPTIDE (PIP) 1 and ... -
Phytotoxic Effects of Catnip (Nepeta meyeri Benth.) on Early Growth Stages Development and Infection Potential of Field Dodder (Cuscuta campestris Yunck)
Shekari, Farid; Shekari, Fariborz; Najafi, Javad; Abassi, Amin; Radmanesh, Zahra; Bones, Atle M. (Peer reviewed; Journal article, 2022)Dodder (Cuscuta campestris Yunck.) is one of the most devastating parasitic plants, which reduces quantity and quality of crops. The inhibitory effect of catnip (Nepeta meyeri Benth.) extracts on germination and some ... -
The IDA-LIKE peptides IDL6 and IDL7 are negative modulators of stress responses in Arabidopsis thaliana
Vie, Ane Kjersti; Najafi, Javad; Winge, Per; Cattan, Ester; Wrzaczek, Michael; Kangasjärvi, Jakko; Miller, Gad; Brembu, Tore; Bones, Atle M. (Journal article; Peer reviewed, 2017)Small signalling peptides have emerged as important cell to cell messengers in plant development and stress responses. However, only a few of the predicted peptides have been functionally characterized. Here, we present ... -
The IDA/IDA-LIKE and PIP/PIP-LIKE gene families in Arabidopsis: phylogenetic relationship, expression patterns and transcriptional effect of the PIPL3 peptide
Vie, Ane Kjersti; Najafi, Javad; Liu, Bin; Winge, Per; Butenko, Melinka Alonso; Hornslien, K; Kumpf, Robert; Aalen, Reidunn B.; Bones, Atle M.; Brembu, Tore (Journal article; Peer reviewed, 2015)Peptide ligands play crucial roles in the life cycle of plants by modulating the innate immunity against pathogens and regulating growth and developmental processes. One well-studied example is INFLORESCENCE DEFICIENT IN ...
