Microsatellite markers in an invasive strain of Asparagopsis taxiformis (Bonnemaisoniales, Rhodophyta): Insights in ploidy level and sexual reproduction

Taxonomy of Marine Macroalgae Used as Sources of Bioactive Compounds

“…However, molecular studies have characterized several species, revealing a higher genetic diversity than previously understood (Andreakis et al 2004(Andreakis et al , 2007a(Andreakis et al , 2007bSalvador et al 2008 ;Sherwood 2008 ) . Asparagopsis taxiformis , a tropical seaweed found widely in nature, is a species that has been investigated in great detail.…”

“…This has resulted in cryptic introductions going unnoticed in some regions (Sherwood 2008 ) . One of these lineages has assumed an invasive behavior and has become widespread in the western Mediterranean in recent years; it is believed that the development of these traits is linked to polyploidy (Andreakis et al 2007b ) . In consideration of these fi ndings, it is highly desirable that future studies on bioactivities in the Bonnemaisoniales provide a detailed molecular characterization of the material used.…”

Structure and temporal dynamics of a seaweed assemblage dominated by the invasive lineage 2 of Asparagopsis taxiformis (Bonnemaisoniaceae, Rhodophyta) in the Alboran Sea

“…In the Mediterranean basin, lineage 2 (IL2) is regarded as invasive. These populations are thought to have an Indo-Pacific origin and are the result of multiple introduction events (Andreakis et al, 2007). In 2008, Altamirano et al reported both life stages on Andalusian coasts, and confirmed its invasive status in the area (in the sense suggested by Boudouresque & Verlaque, 2010).…”

“…These filaments are born from microscopic carposporophytes (2n) that remain attached to the GMP. Studies on the genetic composition of worldwide populations have shown that A. taxiformis is a species complex composed of six cryptic lineages (Andreakis et al, 2007(Andreakis et al, , 2016Dijoux et al, 2014) with different geographical distributions. Only two of these lineages have invasive characteristics (Andreakis et al, 2007;Bolton et al, 2011).…”

Only two of these lineages have invasive characteristics (Andreakis et al, 2007;Bolton et al, 2011). Recent studies have shown that these cryptic lineages present different morphological (Zanolla et al, 2014) and photosynthetic characteristics (Zanolla et al, 2015).…”
