ArborGen chief executive Andrew Baum said the regulatory process improvements would be welcomed by the biotech community.
"It is an excellent step forward for all stakeholders, and ArborGen remains committed to work with the [US Department of Agriculture] to ensure efficient and timely approval of biotechnology products under this streamlined process," Baum said.
ArborGen was forced to defer a planned initial public offering in the US last year because of the volatility that prevailed in equity markets at the time.
News of the deferred IPO took a heavy toll on Rubicon's shares, which have shed more than 70 per cent over the past year and closed up 2c, or 5.4 per cent, at 39c last night.
Rubicon, which listed on the NZX in 2001, was formed out of the separation of Fletcher Challenge Group when it acquired the biotech assets of Fletcher Challenge Forests.
At the start of this month the company reported a net loss of US$8 million for the six months to December 31, 2011.
