The citrus collection at Riverside is our current source of material, and we have been strategically selecting high-priority materials for the California industry from that collection as some of the first to be cryopreserved here at NCGRP," says Volk.
This work also has benefits for conservators of genetic resources, like the NCGRP, that gather and store genetic materials.
Fortunately, genetic materials at NCGRP are stored under optimal conditions and are at lower risk for degradation.
But the plants don't always make seeds, so NCGRP plant physiologist Gayle Volk and ARS colleagues developed cryopreservation methods for shoot tips that will form new plants.
NCGRP provides long-term, backup storage for about 78 percent of the more than 470,000 plant germplasm accessions within the National Plant Germplasm System and about 300,000 units of semen, embryos, and blood from about 120 livestock breeds collected by the U.
Nass and NCGRP curator David Ellis are coordinating the international germplasm exchange from Fort Collins, but it includes all the curators within the U.
We are one of the largest, most effective genebanks in the world," says NCGRP director Henry L.
Seeds at the NCGRP are stored at either -18[degrees]C (0[degrees]F) or -150[degrees]C (-238[degrees]F).
Another new aspect of the NCGRP research is the work on plants native to U.
