Raffinose content may influence cottonseed susceptibility to aflatoxin contamination.

The effect of the cotton storage trisaccharide raffinose and cottonseed storage protein (CSP) in combination on aflatoxin production by Aspergillus flavus was investigated.  Dose response data showed that utilisation of raffinose as a sole carbon source supported growth and aflatoxin production by A. flavus.   When raffinose was a carbon source and CSP was the sole nitrogen source, aflatoxin levels were stimulated up to fourfold above those in raffinose reference media.  Results with ground whold cottoneed as a sole carbon/nitrogen source demonstrated the capacity for aflatoxin production in A. flavus cultures.  Lipid extraction of ground whole seed severely reduced aflatoxigenesis potential.  However, lipid extration  followed by water extraction of ground whole seed restored much of the aflatoxin biosynthetic potential, suggesting the presence of a water solugble inhibitory factor.
