isolation and characterisation of plant defensins from seeds of asteraceae, fabaceae, hippocastanaceae and saxifragaceae.from seeds of aesculus hippocastanum, clitoria ternatea, dahlia merckii and heuchera sanguinea five antifungal proteins were isolated and shown to be homologous to plant defensins previously characterised from radish seeds and gamma-thionins from poaceae seeds. based on the spectrum of their antimicrobial activity and the morphological distortions they induce on fungi the peptides can be divided into two classes. the peptides did not inhibit any of three different alpha-amylases.19957628617
anti-inflammatory, analgesic and antipyretic properties of clitoria ternatea root.clitoria ternatea roots methanol extract when given by oral route to rats was found to inhibit both the rat paw oedema caused by carrageenin and vascular permeability induced by acetic acid in rats. moreover, the extract exhibited a significant inhibition in yeast-induced pyrexia in rats. in the acetic acid-induced writhing response, the extract markedly reduced the number of writhings at doses of 200 and 400 mg/kg (p.o.) in mice.200312781804

a high-throughput peptidomic strategy to decipher the molecular diversity of cyclic cysteine-rich peptides.cyclotides are plant cyclic cysteine-rich peptides (crps). the cyclic nature is reported to be gene-determined with a precursor containing a cyclization-competent domain which contains an essential c-terminal asn/asp (asx) processing signal recognized by a cyclase. linear forms of cyclotides are rare and are likely uncyclizable because they lack this essential c-terminal asx signal (uncyclotide). here we show that in the cyclotide-producing plant clitoria ternatea, both cyclic and acyclic produc ...201626965458
gene coevolution and regulation lock cyclic plant defence peptides to their targets.plants have evolved many strategies to protect themselves from attack, including peptide toxins that are ribosomally synthesized and thus adaptable directly by genetic polymorphisms. certain toxins in clitoria ternatea (butterfly pea) are cyclic cystine-knot peptides of c. 30 residues, called cyclotides, which have co-opted the plant's albumin-1 gene family for their production. how butterfly pea albumin-1 genes were commandeered and how these cyclotides are utilized in defence remain unclear. t ...201626668107
