Summary A genomic clone coding for a putative lipid transfer protein was isolated from Nicotiana tabacum . The gene is expressed in all aerial organs of the tobacco plant, with expression being highest in the upper part of the plant and declining towards the base (i.e. with increasing age). In the shoot apex transcript levels are highest in the LI layer, lower in the underlying cell layers, and are again higher in the submeristem region. This pattern is markedly different from those previously described for genes expressed within the shoot apex.
