Physical mapping of the 5S and 18S–25S rRNA genes by FISH as evidence that Arachis duranensis and A. ipaensis are the wild diploid progenitors of A. hypogaea (Leguminosae)

The 5S and the 18S–25S rRNA genes were physically mapped by fluorescent in situ hybridization (FISH) in all botanical varieties of cultivated peanut Arachis hypogaea (2 n = 4 x = 40), in the wild tetraploid A. monticola , and in seven wild diploid species considered as putative ancestors of the tetr...
