Young leaves of wheat exhibit a smooth developmental gradient with meristematic cells at the base and highly differentiated cells at the tip. During differentiation, mesophyll cells attain a lobed outline resembling tube-shaped balloons with almost regularly spaced isthmi. Microfilament patterns in developing wheat mesophyll cells were investigated using fluorescent-labeled phalloidin. Various patterns were found, including delicate arrays of transversely oriented microfilaments in the cortex of the cytoplasm. A close correlation between changes in the patterns of cortical microfilaments, microtubules, cell wall microfibrils, and cell shape was observed. The fine arrays of transversely oriented microfilaments coaligned with bands of microtubules occurring during cell elongation. These bands were found beneath sites of intense wall deposition. It has recently been proposed that the resulting hoops of wall reinforcement prevent cell expansion in the corresponding regions and thus give rise to the peculiar cell shape. When cell expansion ceased, and the typical lobed cell shape was attained, a dense network of microfilaments was retained in the cytoplasm, which was in contrast to what has been described for the microtubular arrays.
