Upland rice grows on 19 million ha, about 15% of the world's rice plantation [2]. The production of upland rice is crucial to agricultural economy of many countries [15]. The yield of upland rice is very low with an average of about 1 t/ha. Drought is a major constraint to the productivity of upland rice.

The disaccharide galactosea1,3galactose (theaGal epitope) is the major xenoantigen responsible for the hyperacute vascular rejection occurring in pig-to-primates organ trans-plantation. The synthesis of theaGal epitope is catalyzed by the enzyme a1,3-galactosyltransferase (a1,3GalT). To be able to control porcinea1,3GalT gene expression speci®c-ally, we have analyzed the upstreamportionof thea1,3GalT gene, and identi®ed the regulatory sequences.

The Government of Vietnam (GoV) has embarked on a massive tree plantation program. By 2010 it plans to establish an additional 5 million hectares of plantations on cleared land, over and above the current plantation estate of one million hectares, plus the equivalent of more than 50,000 hectares of community forests in scattered plantings. The GoV is committed to improving the quantity and quality of tree seed produced from its own seed orchards, which is a more sustainable strategy than depending on imported seed.

Provenance • Place where seed was collected • Refers to natural forests, not plantations • Provenance boundaries not always well defined • Provenances may have different genetic adaptation. Subdivision of a species, with genetically similar individuals. • Sometimes synonymous with provenance. • Races separated using observed differences. • For example, wood basic density, bark thickness, and flowering patterns have been used to define E. globulusraces

In recent years Vietnam’s forest coverage has undergone rapid expansion, with a marked increase in plantings of exotic species of Eucalyptus, Acacia and Pinus. This expansion provides excellent opportunities for new international export markets for timber products. However it also represents new and increased risks from forestry pests and diseases, which in outbreak circumstances can have catastrophic consequences on plantation establishment and productivity. These risks come from pest and disease species already established in Vietnam, and exotic species not yet present in the country....
