fruit ripening) are being pursued (Sharma et al., 2003). The hope is that the ef<strong>for</strong>ts in these<br />
countries will provide a number of products of value <strong>for</strong> these nations and the region.<br />
The future role of biotechnology in the developing world has been examined. A recent<br />
FAO report (FAO, 2004) rein<strong>for</strong>ced the potential value of agricultural biotechnology in helping<br />
the poor. Since the technology is scale-neutral, even small farmers in developing countries can<br />
gain economic, environmental, and social benefits from the adoption of crops improved by biotechnology.<br />
CHALLENGES FACING AGRICULTURAL BIOTECHNOLOGY<br />
As described in the previous sections, biotechnology-derived crops have provided significant<br />
value to growers, the environment, and the public and have the potential to provide even<br />
greater value with the traits currently in the developmental pipeline. However, there are some<br />
challenges that will impact the introduction of these products. One of these is the significant<br />
costs and time associated with obtaining regulatory approvals.<br />
Impacts of Regulatory Requirements and Processes<br />
The regulatory requirements <strong>for</strong> products produced by recombinant DNA techniques are<br />
considerably greater than those required by techniques that are considered to be part of conventional<br />
breeding, even though conventional breeding may utilize techniques that are comparably<br />
sophisticated and “modern” (e.g., mutagenesis by gamma irradiation and plant tissue culture and<br />
regeneration) and can have comparable results. Crops that have been developed with tolerance to<br />
imidazolinone- and sulfonylurea-based herbicides (e.g., IMI maize 1 and Clearfield ® wheat) are<br />
examples. These herbicide-tolerant crops have required considerably less regulatory review than<br />
the herbicide-tolerant crops containing a gene from a glyphosate-tolerant strain of Agrobacterium<br />
(e.g., the various Roundup Ready 2 crops).<br />
The additional regulatory requirements <strong>for</strong> biotechnology-derived crops have increased the<br />
costs (both pre- and post-commercial) and time to market compared to conventionally developed<br />
crops and have reduced the number and types of products being developed. Although there are<br />
no studies known that have specifically examined this issue in detail, this is a widely-held view<br />
among many academic and industry scientists 3 (Damodaran, 2004; De Greef, 2004; Kalaitzandonakes,<br />
2004) and is credited with the current delays in the development of golden rice<br />
(Potrykus, 2004).<br />
Current Status of Regulatory Requirements <strong>for</strong> Biotech Traits Combined by Conventional<br />
Breeding<br />
Regulations proposed to cover biotechnology-derived traits that have been combined by<br />
conventional breeding (termed “combined-trait products” or “stacks”) are a more recent example<br />
of the expansion of regulatory requirements <strong>for</strong> biotechnology-derived crops. The combination<br />
of separately selected traits is routinely used in seed variety development by conventional breeders.<br />
For example, in maize a number of mutants have been identified that affect carbohydrate<br />
metabolism. 4 The genes carrying these mutations have been combined by conventional breeding<br />
to produce sweet corn and field corn varieties with multiple and different food and feed uses<br />
1 IMI corn (maize) was developed by American Cyanamid and first marketed by Pioneer in 1991 (Ritchie, 1998).<br />
® Clearfield is a registered trademark of BASF Corporation. Clearfield wheat was developed through mutagene-<br />
sis (Lyon, 2003).<br />
2 Commercial Roundup Ready crops include maize, soy, canola, and cotton.<br />
3 Nicholas Kalaitzandonakes, professor of agribusiness and director of the Agribusiness Center at the University<br />
of Missouri at Columbia, is planning such a study and has communicated that this view is consistent with his<br />
interactions with scientists to date.<br />
