Última Codominant inheritance of polymorphic color variants of Gracilaria domingensis (Gracilariales, Rhodophyta) Genet. Mol. Biol. Plastino,Estela M.; Guimarães,Melina; Matioli,Sergio R.; Oliveira,Eurico C.. 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 codominant alleles, where the green and red phenotypes are homozygous, and the heterozygotes present a brownish color. Heterozygous tetrasporophytes, at least until they are 4-5 cm long, exhibit a parental influence on the female gametophyte, since...

Bras. Bot. Bandeira-Pedrosa,Maria Elizabeth; Pereira,Sonia M.B.; Oliveira,Eurico C.. Halimeda is a genus of calcified coenocytic green algae with a well known ecological importance in some tropical areas. Bleached calcified segments of Halimeda may accumulate in large deposits of economic potential as is the case in the northeastern coast of Brazil. In a survey of the genus in Brazil based on recent collections and examination of abundant material deposited on Brazilian herbaria we identified seven species: Halimeda cuneata Hering, H. discoidea Decaisne, H. gracilis Harvey ex J. Agardh, H. incrassata (Ellis) Lamouroux, H. opuntia (Linnaeus) Lamouroux, H. simulans Howe and H. tuna (Ellis & Solander) Lamouroux. These species are described in detail, with emphasis on diagnostic characters. Our study has shown that the shape and size...

Bras. Bot. Horta,Paulo A.; Yokoya,Nair S.; Guimarães,Silvia M.P.B.; Bacci,Denise S.; Oliveira,Eurico C.. Hypoglossum hypoglossoides (Stackhouse) Collins & Hervey is reported for the first time from the infralittoral of São Paulo and Santa Catarina states. The species was already reported to the states of Rio de Janeiro, Espírito Santo and Bahia as Hypoglossum tenuifolium (Harvey) J. Agardh var. carolinianum Williams. A detailed description of the morphology and reproduction is given based on field-collected material. Unialgal cultures were initiated from tetraspore germination, and growth rates of gametophytes were determined under different conditions of temperature, photoperiod and irradiance. Gametophytes grew well between 15 to 30 ºC, 14L:10D and 10L:14D photoperiods and irradiance from 20 to 120 µmol photons.m-2.s-1, but presented low percentage...
