Comparison of constitutive and inducible maize kernel proteins of genotypes resistant or susceptible to aflatoxin production.

Maize genotypes resistant or susceptible to aflatoxin  production or contamination were  compared for differences in both  constiutive and inducible  proteins.  Five  additional  constitutive proteins were  found to be associated with  resistance  in over 8 of  the 10  genotypes  examined.  Among  these,  the 58-  and  46-kDa   proteins  were identified ad globulin-1  and  gkibykub-2,  respectively.  Differences in   the  ability  to induce  specific  antifungal  proteins,  such  as  the  higher  synthesis  of   the  22-kDa  zeamatin  in  resistant  geno- types, were also  abserved between  resistant  and  susceptible  kernels.  Both  constitutive  and inducible  proteins  appear  to be  necessary for  kernel  resistance.
