  abstract = {{P}hylogenetic relationships based on internal transcribed spacer ({ITS}) sequences were used to assess evolutionary trends in genome structure within the genus {P}ennisetum on the basis of observed variations in genome size, basic chromosome numbers (x=5, 7, 8 and 9) and ploidy level (from 2x to 8x). {T}he evolutionary reconstruction is congruent with the gene pool classification and in agreement with some morphological grouping. {P}earl millet, {P}. glaucum, together with elephant grass, {P}. purpureum, form a monophyletic group with a basic chromosome number of x=7 but different chromosome sizes. {T}he ancestral characters of the genus are x=9 small chromosomes, an apomictic mode of reproduction and a perennial life cycle. {S}pecies with basic chromosome numbers of x=5, 7 and 8 appear in the most recently divergent clades, indicating that the genome structure in {P}ennisetum might have evolved towards a reduced chromosome number and an increased chromosome size.},
