Development and characterization of microsatellite markers in two agarophyte species, Gracilaria birdiae and Gracilaria caudata (Gracilariaceae, Rhodophyta), using next-generation sequencing

Development and characterization of microsatellite markers in two agarophyte species Gracilaria birdiae and G. caudata (Gracilariaceae, Rhodophyta) using next-generation sequencing

Delimitating cryptic species in the Gracilaria domingensis complex (Gracilariaceae, Rhodophyta) using molecular and morphological data.

Species in the genus Gracilaria that display conspicuously flattened vegetative morphologies are a taxonomically challenging group of marine benthic red algae. This is a result of their species richness, morphological similarity, and broad phenotypic plasticity. Within this group, the Gracilaria domingensis complex is one of the most common, conspicuous, and morphologically variable species alo...

Transcriptome profiling of sulfate deprivation responses in two agarophytes Gracilaria changii and Gracilaria salicornia (Rhodophyta)

Seaweeds survive in marine waters with high sulfate concentration compared to those living at freshwater habitats. The cell wall polymer of Gracilaria spp. which supplies more than 50% of the world agar is heavily sulfated. Since sulfation reduces the agar quality, it is interesting to investigate the effects of sulfate deprivation on the sulfate contents of seaweed and agar, as well as the met...

Influence of Depth on the Growth of the Seaweed Gracilaria Birdiae (rhodophyta) in a Shrimp Pond

Oliveira, V. P.; Freire, F. A. M. & Soriano, E. M. 2012. Influence of depth on the growth of the seaweed Gracilaria birdiae (Rhodophyta) in a shrimp pond. Braz. J. Aquat. Sci. Technol. 16(X): 33-39. eISSN 1983-9057. This study evaluates the influence of depth and environmental parameters on the development of Gracilaria birdiae Plastino & Oliveira (Gracilariaceae) in an organic shrimp pond. The...

Histórico de vida de espécimens selvagens e variantes cromáticas de Gracilaria birdiae (Gracilariales, Rhodophyta)

têm sido estudadas visando a obtenção de condições ideais de cultivo, bem como a seleção de linhagens mais adequadas à maricultura (Patwary & van der Meer 1982, van der Meer & Patwary 1983, Zhang & van der Meer 1987). O manejo bem sucedido de uma espécie está condicionado ao conhecimento de sua biologia. Portanto, o histórico de vida tem sido objeto de estudo em muitas espécies de Gracilaria, c...
