Possible Role of Crystal-Bearing Cells in Tomato Fertility and Formation of Seedless Fruits.

Crystal-bearing cells or idioblasts, which deposit calcium oxalate, are located in various tissues and organs of many plant species. The functional significance of their formation is currently unclear. Idioblasts in the leaf parenchyma and the development of crystal-bearing cells in the anther tissues of transgenic tomato plants ( L.
