Visualizing organelles in living cells is a powerful method to analyze their intrinsic mechanisms. Easy observation of chlorophyll facilitates the study of the underlying mechanisms in chloroplasts, but not in other plastid types. Here, we constructed a transgenic plant enabling visualization of plastids in pollen grains. Combination of a plastid-targeted fluorescent protein with a pollen-specific promoter allowed us to observe the precise number, size and morphology of plastids in pollen grains of the wild type and the ftsZ1 mutant, whose responsible gene plays a central role in chloroplast division. The transgenic material presented in this work is useful for studying the division mechanism of pollen plastids.
