cDNA cloning of water deficit-inducible genes from loblolly pine
Pine trees produce new proteins when growing under water deficit and this is achieved principally by activating formerly quiescent genes. Determining the identity of these genes, how they sense changes in the environment and the role their proteins play in drought tolerance is important for an appreciation of tree growth under stress and for emerging biotechnologies. We have isolated cDNA clones (DNA copies of the mRNA) of drought-induced genes from Loblolly Pine (Pinus taeda). DNA sequencing and computer aided comparisons reveal strong similarities between these pine clones and stress-induced genes in other plants, particularly those involved in lignin synthesis.
