Abstract

The distribution of cytoplasmic DNA in generative and sperm cells of four species in four

genera in the Convolvulaceae, i. e. , Calonyction aculeatum , Ipomoea aquatica , Quamoclit pennata

and Cuscuta japonica, has been detected using DAPI fluorescent staining method. Cytoplasmic DNA

is found to occur in generative and sperm cells of all the species except for Cuscuta japonica. This

result, together with the previous reports that cytoplasmic DNA is also distributed in male cells of

five species in Ipomoea, Pharbitis and Calystegia, may indicate that the presence of cytoplasmic

DNA in generative and sperm cells is a general feature of the Convolvulaceae. The absence of such

DNA in male cells in the genus Cuscuta supports the establishment of this genus as an independent

family, the Cuscutaceae.

Key words： Convolvulaceae; Cuscutaceae; Cytoplasmic DNA; Cytoplasmic inheritance; Systematics
