USDA deregulates MON87460 maize
The USDA’s Animal and Plant Health Inspection Service (APHIS) has granted deregulated status to Monsanto’s drought-tolerant genetically modified maize event, MON87460. The line expresses a cold shock protein B, derived from the bacterium, Bacillus subtilis, which helps maintain plant cellular functions. It is expected to reduce yield loss under water-limited conditions compared with conventional maize. Data suggest that MON87640 reduces yield loss primarily through increased kernel number per ear under water-limited conditions by minimising its effect on photosynthesis, stomatal conductance and carbon fixation. MON87460 received food and feed use clearances from the US Food and Drug Administration in December 2010. The APHIS proposed deregulation of MON87640 in May 2011 ( Agrow No 617, p 23).
