1964D. R. Perrin in Tetrahedron Lett. viii. 438 The author's attention has been drawn to the prior use of the term phaseolin to denote a protein from Phaseolus vulgaris. Accordingly the name of the phytoalexin from P. vulgaris is now changed to phaseollin. 1964Cruickshank & Perrin in J. B. Harborne Biochem. Phenolic Compounds xiii. 530 Phaseollin is similar in its biological properties to pisatin. 1967R. K. S. Wood Physiol. Plant Path. xiv. 497 Another phytoalexin, closely related to pisatin and called phaseollin has now been obtained from pods of French bean (Phaseolus vulgaris) inoculated with conidia of S[clerotinia] fructicola. 1973Nature 20 Apr. 533/1 The phytoalexin phaseollin does accumulate in hypersensitive responses in leaves of French bean..caused by avirulent bacteria but this substance has little or no effect on growth of bacteria. |
