The Evolution of Chili Peppers (Capsicum - Solanaceae): A Cytogenetic Perspective

Meiotic analysis of interspecific hybrids between Capsicum frutescens and Capsicum chinense

“…The meiotic analysis of the hybrids allowed observing 12 chromosomes in bivalent association in diakinesis (Figure 1a), corroborating the literature for diploid parental species, with 2n=2x=24 chromosomes (Pozzobon et al 2006, Moscone et al 2007). This result is expected, since the parental species, C. frutescens and C. chinense, differ only by the presence of an annular constriction in the calyx, typical of the species C. chinense (IPGRI 1995).…”

“…annuum; C. baccatum var. baccatum; C. chinense; C. frutescens, and C. pubescens (Pickersgill 1991, Moscone et al 2007. Within this genus, species can be distinguished in two groups, according to the basic number of chromosomes: one with n = x = 12 chromosomes, and another with n = x = 13 chromosomes (Moscone et al 2007).…”

Morphological characterization and analysis of genetic variability among pepper accessions

“…Brazil is a diversity center for the genus, housing domesticated, semi-domesticated and wild species (MOSCONE et al, 2007).…”

“…Pepper plants are preferably autogamous, diploid with 2n=2x=24 or 2n=2x=26 chromosomes and have pungency as a marking characteristic, which is attributed to the alkaloid substances, more specifically the capsaicinoids (MOSCONE et al, 2007).…”

Karyotypes and fluorescent chromosome banding patterns in southern AfricanLycium(Solanaceae)

“…Karyotypic patterns have proven useful in understanding evolutionary trends and systematic relationships in several angiosperm groups (e.g., SHAN et al 2003;WEISS-SCHNEEWEISS et al 2003;URDAMPILLETA et al 2005), and in Solanaceae in particular, i.e., the genera Benthamiella, Combera, and Pantacantha (MOSCONE 1989), Solanum section Basarthrum (BERNARDELLO and ANDER-SON 1990), Solanum section Lasiocarpa (BER- NARDELLO et al 1994), and Capsicum (MOSCONE et al 2007).…”
