Studies on the molecular biology of nutrient storage in trees have largely dealt with nitrogen storage and retranslocation. Vegetative storage proteins, which are storage forms of reduced N, are prevalent in many forest species and are an ideal target for tree improvement at the molecular level. Vegetative storage proteins have been correlated to nutrient cycling, fast growth, winter hardiness, and dormancy. They are found in bark, wood, roots, and leaves and comprise over 25% of total soluble protein in these tissues of many species. An understanding of vegetative storage protein genes and their expression could lead to use of these genes for genetic transformation experiments with the aim of manipulating such characteristics as biomass production, rate of spring growth, frost hardiness, nutrient cycling, and resistance to pathogens.
