Small cysteine-rich peptides resembling antimicrobial peptides have been under-predicted in plants.
Multicellular organisms produce small cysteine-rich antimicrobial peptides as an innate defense against pathogens. While defensins, a well-known class of such peptides, are common among eukaryotes, there are other classes restricted to the plant kingdom. These include thionins, lipid transfer proteins and snakins. In earlier work, we identified several divergent classes of small putatively secr...
متن کاملPlant antimicrobial peptides
Pathogens, like fungi, nematodes, virus and bacterial are responsible for several human and plant diseases. According FAO, around 20 to 40 percent of crops yields are lost, per year, due plant diseases and pest. Besides this, only USA spend 30 billion dollars a year with hospital infections, and the numbers are increasing as the infection are becoming more and more resistant to conventional ant...
متن کاملInteractions of AsCy3 with Cysteine-Rich Peptides
There is great interest in fluorogenic compounds that tag biomolecules within cells. Biarsenicals are fluorogenic compounds that become fluorescent upon binding four proximal Cys thiols, a tetracysteine (Cys(4)) motif. This work details interactions between the biarsenical AsCy3 and Cys(4) peptides. Maximal affinity was observed when two Cys-Cys pairs were separated by at least 8 amino acids; t...
متن کاملCysteine-rich peptides (CRPs) mediate diverse aspects of cell-cell communication in plant reproduction and development.
Cell-cell communication in plants is essential for the correct co-ordination of reproduction, growth, and development. Studies to dissect this mode of communication have previously focussed primarily on the action of plant hormones as mediators of intercellular signalling. In animals, peptide signalling is a well-documented intercellular communication system, however, relatively little is known...
متن کاملTryptophan-rich antimicrobial peptides: properties and applications
There is a world-wide quest for development of new-generation antibiotics, due to the emergence of microbial pathogens that have developed resistance to the currently available antibiotics. The antimicrobial peptides (AMPs) are a strong candidate in this regard, due to minimal possibilities of emergence of resistance against these. The tryptophan (Trp)-rich peptides comprise an important class ...
