  abstract = {{C}hili peppers ({S}olanaceae family) have great commercial value. {T}hey are commercialized in natura and used as spices and for ornamental and medicinal purposes. {A}lthough three whole genomes have been published, limited information about satellite {DNA} sequences, their composition, and genomic distribution has been provided. {H}ere, we exploited the noncoding repeti-tive fraction, represented by satellite sequences, that tends to accumulate in blocks along chromosomes, especially near the chromosome ends of peppers. {T}wo satellite {DNA} sequences were identified ({CDR}-1 and {CDR}-2), characterized and mapped in silico in three {C}apsicum genomes ({C}. annuum, {C}. chinense, and {C}. baccatum) using data from the published high-coverage sequenc-ing and repeats finding bioinformatic tools. {L}ocalization using {FISH} in the chromosomes of these species and in two others ({C}. frutescens and {C}. chacoense), totaling five species, showed signals adjacent to the r{DNA} sites. {A} sequence comparison with existing {S}olanaceae repeats showed that {CDR}-1 and {CDR}-2 have different origins but without homology to r{DNA} sequences. {S}atellites occupied subterminal chromosomal regions, sometimes collocated with or adjacent to 35{S} r{DNA} sequences. {O}ur results expand knowledge about the diversity of subterminal regions of {C}apsicum chromosomes, showing different amounts and distributions within and between karyotypes. {I}n addition, these sequences may be useful for future phylogenetic studies.},
