✦ Synopsis

A recent publication on stress metabolites produced by potato tubers' includes a proposed structure (I) for phytuberin, an antifungal compound first investigated by Varns' in studies on the resistance of potato tuber slices to infection by the late blight fungus Phytophthora infestans. We have isolated phytuberin from potato tubers inoculated with the bacterium Erwinia carotovora vak-atrose&ica' and our spectral and chemical observations leading to a revised structure (IIa) are given below. Phytuberin, C H 0 (M+'Z94) is a neutral oil which gave no reactions for hydroryl, 17 26 4

From seeds of Nigella sativa L. (Ranunculaceae), an endemic plant of Uzbekistan, two novel defensins named Ns-D1 and Ns-D2, were isolated and sequenced. The peptides differ by a single amino acid residue and show high sequence similarity to Raphanus sativus L. defensins Rs-AFP1 and Rs-AFP2. The Ns-D
