Codominant inheritance of polymorphic color variants of Gracilaria domingensis (Gracilariales, Rhodophyta)

Abstract: Agar is the most valuable phycocoloid in the world market. Currently, about half of its production is obtained from the red alga Gracilaria (Gracilariales, Rhodophyta). Consequently, this genus has been the subject of many studies worldwide. A common green color variant of G. domingensis (Kützing) Sonder ex Dickie was found in a natural population on the northeastern coast of Brazil. Crosses were performed to determine the mode of color inheritance. The results can be interpreted as the expression of a pair of… Show more

“…Este hecho podría sugerir que los ejemplares verdes tienen las mismas capacidades fisiológicas, por lo menos en las condiciones de laboratorio utilizadas. Por otro lado, es sabido que las variantes verdes de diferentes especies son deficientes en ficoeritrina (Doty et al 1987, Paula et al 1999, Plastino et al 1999, Costa & Plastino 2011, producto de una sobreexpresión de la ficocianina y aloficocianina, enmascarando la coloración roja característica en Rhodophyta (Aguirre-von-Wobeser et al 2001). Diferencias en concentración de pigmentos puede influenciar la eficiencia fotosintética y consecuentemente comprometer el crecimiento y desarrollo.…”

“…This could explain the genetic mosaics that Kain & Destombe (1995) called chimeras, where the fusion of the discs can create complex genetic systems with distinct genotypes in a single thallus. Plastino et al (1999) and Polifrone et al (2006) verified the formation of a sexual mosaic caused by the germination of tetraspores in situ and the development of gametophytes in the same thallus of the tetrasporophytes. Another factor that could explain the presence of the so-called chimeras is the germination of the carpospores inside of the cystocarp, giving rise to a system where the female gametophyte (haploid) acts as a support for the tetrasporophyte (diploid) (Figure 1).…”

“…In Porphyra, segregation of the green mutation was a key feature in identifying the position of meiosis (Ma and Miura 1984). Colour mutants have also provided important model systems for studying mechanisms of inheritance in red algae in a variety of genera including Chondrus (e.g., van der Meer 1981) and Gracilaria (Plastino et al 1999, 2004, Costa and Plastino 2011. Some of these mutants may be artificially produced by various chemical (e.g., Yan et al 2000) or radiation treatments (e.g., Niwa et al 2009), or spontaneously occur in culture (e.g., Chondrus) (van der Meer 1981, Staples et al 1995 such as the Chondrus used in this study.…”
