Plants and CRISPR

So much of the CRISPR wars have focused on human intervention. However the impact in the plant world is extraordinary. After all we have to eat.

Dupont Pioneer had announced a major effort worth the look.

DuPont Pioneer today announced waxy corn hybrids as its first commercial agricultural product developed through the application of CRISPR-Cas enabled advanced breeding technology. This next generation of elite waxy corn hybrids is expected to be available to U.S. growers within five years, pending field trials and regulatory reviews. "We’re applying our 90 years of knowledge of corn biology to develop the next generation of high-quality waxy corn hybrids for the benefit of the entire value chain from growers to processors and end users," said Neal Gutterson, vice president, research and development for DuPont Pioneer. "Starting with an identity-preserved product as our initial CRISPR-Cas offering allows us to lay a solid foundation for success of future larger volume products from this plant breeding innovation." Pioneer is the leading supplier of waxy corn hybrids globally. In the United States, about a half-million acres of waxy corn are grown each year; however, they traditionally yield less than non-waxy corn hybrids. Waxy corn produces a high amylopectin starch content, which is milled for a number of everyday consumer food and non-food uses including processed foods, adhesives and high-gloss paper. Waxy corn is typically grown on contract through a closed-loop production system commonly referred to as "identity-preserved." "The next generation of waxy hybrids developed with CRISPR-Cas will represent a step-change in how efficiently we bring elite genetic platforms of high-yielding waxy corn to our customers," Gutterson said. The United States Department of Agriculture (USDA) recently (USDA) recently published its response to Pioneer’s "Regulated Article Letter of Inquiry" stating that it does not consider next-generation waxy corn developed with CRISPR-Cas enabled advanced breeding technology as regulated by USDA Biotechnology Regulatory Services.
