“…Likewise, the placement of Coronanthereae as sister to a clade of all Gesnerioideae except Beslerieae/Napeantheae ( fig. 3) has been seen previously (Smith et al 2006). Comparison between the two topologies indicates that neither the relationships among Coronanthereae that were unique to the reduced analysis nor the placement of the tribe as sister to Gesnerioideae except Napeantheae þ Beslerieae can be rejected in a comparison between the full and reduced analyses and their data sets (table 1).…”

“…We also obtained sequences for the trnL intron (Taberlet et al 1991), ndhF Smith and Atkinson 1998), the rpl20-rps12 spacer (Hamilton 1999), and the low-copy-number nuclear gene GCYC (Smith et al 2004a(Smith et al , 2004b(Smith et al , 2006. Amplification, cloning, and sequencing procedures followed those of Smith et al (2004a) for these latter DNA regions.…”

“…However, the often relatively low variation in chloroplast DNA at the intraspecific level have limited the precision with which polyploidy can be identified [ 17 , 19 ]. Single- and low- copy nuclear genes are less likely subject to concerted evolution, thus making themselves ideal tools for verifying the existence of suspected polyploids [ 20 ], identifying genome donors [ 18 , 21 ], demonstrating multiple polyploid origins [ 19 ], clarifying hybridization events or introgression [ 18 ], and examining gene evolution in polyploids [ 22 ]. Plastid acetyl-CoA carboxylase (ACCase) catalyzes the first step in de novo fatty acid biosynthesis.…”

“…In Gesneriaceae CYC ( GCYC ), duplication events were found to be exceptionally high (Citerne et al, 2000 ; Wang et al, 2004a ; Zhong and Kellogg, 2015 ). Certain GCYC duplications were found that can either predate or postdate the divergence of the family, tribe, and genus level (Smith et al, 2004 , 2006 ; Wang et al, 2004a ). After gene duplication, different selective pressure may be exerted on each duplicate that thus generate functional specializations (Gao et al, 2008 ).…”
