Creator:: Navarre, Duroy A.
Abstract:: Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as the P protein of the glycine decarboxylase complex (GDC)....

Abstract:: Coproporphyrinogen III oxidase (CPX) is an enzyme involved in the biosynthesis of tetrapyrroles, catalyzing the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen IX. In bacteria and yeast this enzyme is cytosolic, in animals it is mitochondrial, and in each it functions to produce heme. However, in all plants investigated, the...

Creator:: Coenen, Catharina
Abstract:: The phytohormones auxin and cytokinin control plant development through a complex network of interactions which include synergistic, additive, and opposite effects whose mechanisms are unknown. The auxin-insensitive diageotropica (dgt) mutant provided a tool to dissect the relationship between auxin- and cytokinin-induced responses in tomato. Morphological, physiological, and molecular data support...

Creator:: Oh, KwangChul
Abstract:: The auxin-resistant diageotropica (dgt) mutant of tomato (Lycopersicon esculentum Mill.) has a pleiotropic phenotype including a lack of lateral roots and reduced gravitropic response, apical dominance, vascular development, and fruit growth. The dgt mutation reduces the auxin sensitivity of only a subset of auxin responses while levels, metabolism, and transport...
