Novel defensin subfamily from spinach ( Spinacia oleracea)

Antimicrobial peptides (So-D1-7) were isolated from a crude cell wall preparation from spinach leaves ( Spinacia oleracea cv. Matador) and, judged from their amino acid sequences, six of them (So-D2-7) represented a novel structural subfamily of plant defensins (group IV). Group-IV defensins were al...

Description
Summary:Antimicrobial peptides (So-D1-7) were isolated from a crude cell wall preparation from spinach leaves ( Spinacia oleracea cv. Matador) and, judged from their amino acid sequences, six of them (So-D2-7) represented a novel structural subfamily of plant defensins (group IV). Group-IV defensins were also functionally distinct from those of groups I–III. They were active at concentrations
