Antagonistic peptide technology for functional dissection of CLE peptides revisited
In the Arabidopsis thaliana genome, over 1000 putative genes encoding small, presumably secreted, signalling peptides can be recognized. However, a major obstacle in identifying the function of genes encoding small signalling peptides is the limited number of available loss-of-function mutants. To overcome this, a promising new tool, antagonistic peptide technology, was recently developed. Here...
متن کاملBreakthrough Technologies Antagonistic Peptide Technology for Functional Dissection of CLV3/ESR Genes in Arabidopsis1[C][W][OA]
In recent years, peptide hormones have been recognized as important signal molecules in plants. Genetic characterization of such peptides is challenging since they are usually encoded by small genes. As a proof of concept, we used the wellcharacterized stem cell-restricting CLAVATA3 (CLV3) to develop an antagonistic peptide technology by transformations of wild-type Arabidopsis (Arabidopsis tha...
متن کاملDiverse and conserved roles of CLE peptides.
The function of plant CLAVATA3 (CLV3)/ENDOSPERM SURROUNDING REGION (ESR) (CLE) peptides in shoot meristem differentiation has been expanded in recent years to implicate roles in root growth and vascular development among different CLE family members. Recent evidence suggests that nematode pathogens within plant roots secrete ligand mimics of plant CLE peptides to modify selected host cells into...
متن کاملPlant CLE peptides from two distinct functional classes synergistically induce division of vascular cells.
The Clavata3 (CLV3)/endosperm surrounding region (CLE) signaling peptides are encoded in large plant gene families. CLV3 and the other A-type CLE peptides promote cell differentiation in root and shoot apical meristems, whereas the B-type peptides (CLE41-CLE44) do not. Instead, CLE41 inhibits the differentiation of Zinnia elegans tracheary elements. To test whether CLE genes might code for anta...
متن کاملCLE peptides control Medicago truncatula nodulation locally and systemically.
The CLAVATA3/embryo-surrounding region (CLE) peptides control the fine balance between proliferation and differentiation in plant development. We studied the role of CLE peptides during indeterminate nodule development and identified 25 MtCLE peptide genes in the Medicago truncatula genome, of which two genes, MtCLE12 and MtCLE13, had nodulation-related expression patterns that were linked to p...
