Summary: This review describes phenomena that are common and unique to organell differentiation during male gametophyte development: (1)selective decreases/increases in plastid and mitochondrial DNA in generative cells just after pollen mitosis one. (PMI), which determine the mode of cytoplasmic inheritance; (2)the unique distribution of mitochondria, which surround the nuclear envelope in a single compact layer, just before and after PMI in Pharbitis nil; (3)the role of CSL1, a novel nuclear protein, in controlling vacuole contraction before and after PMI; and(4)tapetosome differentiation in tapetal cells depending on the sterol content under the control ofHMG1, a key enzyme in the cytosolic isoprenoid biosynthesis pathway in higher plants.
