Genome size in Anthurium evaluated in the context of karyotypes and phenotypes

Abstract

Little is known about the genome of Anthurium other than chromosome observations, which frequently indicate supernumerary (“B”) chromosomes. New genome size estimates for 34 species and nine cultivars presented here provide insights into genome organization and evolution in this very large genus.

Grouping of anthurium genotypes based on genetic and morpho-anatomical features

“…(IFT 258), and also the group of two genotypes not yet identified: IFT 123 and 255. Furthermore, it confirmed that the cultivars Astral and Rubi (IAC) belong to the same genotypes, which was also observed by Bliss and Suzuki (2012), and isolated A. bomplandii, A. gracile and A. affine from the other genotypes. From a practical point of view, determination of the nuclear DNA content can replace chromosome counting, especially when working with a large number of individuals, as in a germplasm bank (Schifino-Wittmann 2001).…”

A universe of dwarfs and giants: genome size and chromosome evolution in the monocot familyMelanthiaceae

“…size and number) are reflected in the GS of organisms and their evolution is intimately linked (e.g. Bliss & Suzuki, 2012;Nam & Ellegren, 2012;Jang et al, 2013;Pellicer et al, 2013). One of the best illustrative examples is that of Parideae, in which the lowest diploid chromosome numbers (2n = 10) in the family, arising from a significant number of chromosome losses (Fig.…”

Anthurium in vitro: A review

“…To address this need in Anthurium tissue culture, and to provide an alternative in vitro regeneration pathway, suitable anther culture systems were developed Mattjik, 2009a, 2009b;Winarto et al, 2010aWinarto et al, ,b, 2011aWinarto and Teixeira da Silva, 2012). Few studies to date have employed flow cytometry and other molecular techniques to understand in more detail the genome and phylogeny of Anthurium spp., although some advances were made fairly recently (Bliss and Suzuki, 2012), while a recent study highlights the genetic mechanisms for the inheritance of color in the spathe (Gopaulchan et al, 2014). An understanding of genome size can be useful for in vitro studies and breeding since genome size is correlated with seed mass, cell and stomatal size, stomatal density, and length of the cell cycle (e.g., Beaulieu et al, 2008), all aspects that are of interest and importance to the culture of Anthurium in vitro.…”
