Identification of chemical components of corn kernel pericarp wax associated with resistance to Aspergillus flavus infection and aflatoxin production.

Kernel  pericarp  wax  of  the corn  breeding  poputation  GT-MAS: gk  has  been  associated with  resistance to Aspergillus  flavus infection and  aflatoxin production.  GT-MAS: gk  wax was  compared  to wax  of  a  group  of susceptible  lines.  Wax separation by TLC  demonstrated a unique GT-MAS: gk  band  and a uniqu “susceptible” band. Only  GT-Mas:gk  wax  inhibited  the growth of A.flavus.  GC-MS  analysis of kernel whole  wax  showed a higher  percentage of phenol-like  compounds  in wax  from GT-MAS :gk than in  waxes  from  the  susceptible  lines.  The  GT-MAS:  gk  unique band  contained  phenol-like  compounds  and  ethyl-hexadecanoate.  Butyl-hexadecanoate  was  pre-eminent in  most  of  the “susceptible bands”.
