Notes: A novel pollen-specific LEA-like protein, LP28, was detected in Lilium longiflorum using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). Immunoblot analysis using antiserum raised against LP28 revealed that the protein was not found in somatic tissues or uninucleate microspores, but accumulated gradually in developing pollen following microspore mitosis. Furthermore, LP28 was abundant in germinated pollen after hydration. The cDNA clone corresponding to LP28 encoded a putative protein of 238 amino acids with a calculated molecular mass of 24·2 kDa and a pI of 4·7. The amino acid sequence is highly hydrophilic except for the N-terminal hydrophobic signal peptide. The sequence has similarities with group 3 LEA (late embryogenesis abundant) proteins. Immunocytochemical analyses demonstrated that LP28 was mainly found in cytoplasmic granules of the vegetative cell until pollen maturation, but after hydration it appeared in the elongating pollen tube wall. LP28 might be a unique pollen-specific protein that is transported to the pollen tube wall after germination. Therefore, it is assumed that LP28 plays a role not only in pollen maturation, but also in the growth of the pollen tube, which penetrates the stylar matrix.
