are composed of two different subunits derived from asingle precursor molecule and are linked by disulfidebridges [11]. Some 2S albumins can also play a physio-logical role in plant defense [23]. For example, 2S albu-mins from radish seeds inhibit the growth of fungi andbacteria, display synergistic activity with thionins of wheator barley origin and promote the permeabilization of theplasma membrane of phytopathogens [24,25]. Recently,two novel proteins with homology to 2S albumins, desig-nated CW-1 and CW-4, were purified and characterizedfrom Malva parviflora seeds and shown to have strongantifungal activity against Fusarium graminearum (CW-1)and Phytophthora infestans (CW-4) [28,29]
