Amino Acid Composition of the Host-specific Toxin of Helminthosporium carbonum.
The host-specific toxin of Helminthosporium carbonum (C(32)H(50)N(6)O(10)) was hydrolyzed by 6 n HCl to yield a number of alpha-amino acids. The common amino acids, proline and alanine, occurred in a ratio of 1:2. Two other unstable alpha-amino acids that produced lower color values with ninhydrin were also produced. One of these was tentatively identified as 2-amino-2,3-dehydro-3-methylpentano...
متن کاملEffects of Helminthosporium carbonum Toxin on Absorption of Solutes by Corn Roots.
Susceptible corn roots exposed to the host-selective toxin of Helminthosporium carbonum took up and retained more NO(3) (-), Na(+), Cl(-), 3-o-methylglucose, and leucine than did control roots. Stimulatory effects on uptake were more pronounced with freshly cut roots than with roots that were washed and aged. Solutes were accumulated against a concentration gradient, and toxin-treated tissues d...

Isolation and characterization of host-selective toxin from Helminthosporium sacchari.
Helminthosporium sacchari infects certain clones of sugar cane and produces a toxin with the same plant selectivity as the fungus itself. The toxin was purified by use of activated charcoal plus thin layer, gel, and ion exchange chromatography. Gas chromatography (GC) of a trimethylsilyl derivative of toxin gave a single peak. Toxin was characterized by GC, mass spectroscopy (MS), and NMR spect...
متن کاملInhibition of maize histone deacetylases by HC toxin, the host-selective toxin of Cochliobolus carbonum.
HC toxin, the host-selective toxin of the maize pathogen Cochliobolus carbonum, inhibited maize histone deacetylase (HD) at 2 microM. Chlamydocin, a related cyclic tetrapeptide, also inhibited HD activity. The toxins did not affect histone acetyltransferases. After partial purification of histone deacetylases HD1-A, HD1-B, and HD2 from germinating maize embryos, we demonstrated that the differe...
