In plants, three main groups of antimicrobial peptides are produced: defensins, thionins
and lipid transfer proteins .
A flower-specific cDNA encoding a novel thionin
A six-cysteine type thionin
from the radish storage organ displays weak in vitro antifungal activity against Fusarium culmorum.
Another protein in the thionin
family--hordothionin--is a target of research by ARS scientists and their colleagues in Madison, Wisconsin.
Tissue was stained with Thionin
and mounted on 3- x 1-inch Corning glass slides for microscopic examination.
These were first described by Ehrlich in 1873 by their ability to stain metachromatically with basic aniline dyes like Toluidine blue, thionin
Culture plates containing Thionin
and Basic Fuchsin dyes did not inhibit the growth of Brucella.

A series of organic dyes,such as methylene blue (MB), methylene green, Prussian blue, phenazines and thionin
, etc, have been used in chemically modified electrode and all displayed excellent mediating ability in electrocatalysis [1-3].
Consequently, plant based compounds like isoflavones, gamma thionin
and homoisoflavinoids have been discovered and studied extensively (Hong et al., 2006; Franco et al., 2006; Mhaeswara et al., 2006).

Defensins were extracted from flowers of Catharanthus roseus(white flower) and (pink flower) by using a modification of the procedure for extraction of thionins
from barley (Hordeumvulgare) flour (Ozaki et al., 1980) and further modification of the procedure used for isolation of floral defensins from ornamental tobacco and petunia(Lay et al., 2003).
