dc.description.abstract
Species of section Arachis with x = 10 areimportant for peanut breeding and have been organizedin five different genomes (A, B, D, F and K). The fewavailable estimates of the DNA content are inconsistentand hampered the understanding of the evolutionarytrends and in decision making for genomic studies of thegroup. Considering that, the objectives of this researchwere to measure the DNA content for all available (26)species and to make evolutionary inferences at thediploid and tetraploid level for section Arachis. The 2Cvalues obtained by flow cytometry ranged from 2.55 to3.22 pg among the diploid species. The annual speciesbelonging to different genomes tend to have differentgenome sizes. However, the 2C values of the perennialspecies of the A genome were distributed almost alongthe whole range of genome sizes here observed. Thedistribution of 2C values partially support the genomearrangement proposed for the section. The comparisonsof 2C values with karyotype parameters suggests thatchanges in DNA content have been proportionallydistributed among the chromosome arms, and that theheterochromatic fractionwas not directly involved in thatchanges. Within the A genome, the annual species haslowerDNAcontent than the perennial ones, according tothe nucleotype hypothesis. However, the lack of significantrelationships with geoclimatic variables suggeststhat there are many intrinsic factors determining particularecological roles of the DNA content in the differentlineages of section Arachis. The constancy of the Cxvalues observed in the polyploids compared to those ofthe parental species suggests that the allopolyploidizationevent that originated the cultivated peanut did notinduce significant changes in the genome size.
