✦ Synopsis

A full-length tomato cDNA clone, TSW 12, which is developmentally and environmentally regulated, has been isolated and characterized. TSWl2 m R N A is accumulated during tomato seed germination and its level increases after NaC1 treatment or heat shock. In mature plants, TSWl2 m R N A is only detected upon treatment with NaC1, mannitol or ABA and its expression mainly occurs in stems. The nucleotide sequence of TSWl2 includes an open reading frame coding for a basic protein of 114 amino acids; the first 23 amino acids exhibit the sequence characteristic of a signal peptide. The high similarity between the TSWl2-deduced amino acid sequence and reported lipid transfer proteins suggests that TSWl2 encodes a lipid transfer protein.
