“…Those variations can reflect the results of various cytological phenomena, especially satellite DNA amplification (Guerra 2000;Silva et al 2010;Ribeiro et al 2016). Differences in heterochromatic banding patterns are quite useful for cytotaxonomic characterizations of plant species, especially among those having karyotypes formed by morphologically similar chromosomes that are numerically stable (Guerra 2000;Scaldaferro et al 2012;Cordeiro et al 2016). The observed differences in the CMA/ DAPI banding patterns in Senna ratified the effectiveness of that technique for facilitating karyological differentiation of its species.…”

“…Among the 10 species analyzed, only three (S. alata, S. obtusifolia, and S. siamea) had previously been examined in terms of their CMA/DAPI banding patterns (Souza & BenkoIseppon 2004 (Dematteis et al 2006), Capsicum (Scaldaferro et al 2012), Allium pulchellum (Vosa 1996), and Pinus nigra (Bogunić et al 2011). Variations in heterochromatin bands between individuals of the same species appear to be an intraspecific cytological characteristic of the genus Senna that is worthy of further investigation, calling for the analysis of distinct populations from different ecosystems and different geographic regions.…”

“…In essence, this feature suggests similar ribosomal copy number in the 5S per genome in the genus. However, Giemsa-C and fluorescence bandings revealed a Giemsa+ and CMA+DAPI-constitutive heterochromatic region (Het) located at the short arm of a unique metacentric chromosome pair at intercalar position, in diverse chili peppers (Moscone et al 2007 and references therein;Scaldaferro et al 2013), that in fact co-localize with the 5S loci. This Het is polymorphic among taxa, regarding presence and size, suggesting variability in the 5S ribosomal copy number in Capsicum.…”

“…Fluorochrome banding or in situ hybridisation may substantially improve the cytogenetic analysis and infer homeologies and differences between species (Robledo & Seijo ; Scaldaferro et al . ). In addition, cytogenetics can implement methods of phylogenetic analyses, allowing statistically informed inferences.…”
