DP56113 SPTA maintainer maize has been genetically engineered for maintenance and recovery of male-sterile maize breeding lines using the same construct and method of transformation as DP-32138-1 SPT maintainer maize. We are making available for public comment the request and our plant pest risk similarity assessment and preliminary determination of nonregulated status.
