Phytotoxins produced byTubakia dryina
Mycopathologia, 1992Tubakia dryina, the causal agent of red oak (Quercus rubra) leaf spot, produced the phytotoxins isosclerone, 3-hydroxyisosclerone, 6-hydroxyisosclerone and 6-hydroxymellein in liquid culture. All toxins caused large necrosis when placed on leaves of red oak. Necrosis was also caused on white oak and eight different weed species.

More chemistry of the thaxtomin phytotoxins
Phytochemistry, 2003Chemical and biochemical studies indicated the possible involvement of N-acetyltryptophan and 4-nitrotryptophan as intermediates in biosynthesis of the thaxtomin phytotoxins. A search for other potential pathways indirectly resulted in the identification of three unusual thaxtomin analogues derived from the o-thaxtomin A isomer.
