Phytotoxicity of solanapyrones A and B produced by the chickpea pathogenAscochyta rabiei (Pass.) Labr. and the apparent metabolism of solanapyroneA by chickpea tissues

摘要

When chickpea shoots were placed in solanapyrone A, the compound could not be recovered from the plant and symptoms developed. These consisted of loss of turgor, shrivelling and breakage of stems and flame-shaped, chlorotic zones in leaflets. In similar experiments with solanapyrone B, only 9.4 % (22 mu g) of the compound taken up was recovered and stems remained turgid but their leaflets became twisted and chlorotic and some abscized.
