Morphogenetic Aspects in Macrocystis Development
Botanical Gazette, 1985Differential growth of the giant kelp, Macrocystis pyrifera, was observed in frond meristems and in young sporophytes at their primary-blade stage. Autoradiographs of plants pulse-labeled with 14C showed both that the carbon was taken up and translocated and that the fixed carbon was diluted in regions of vigorous meristematic growth.

Microsatellite markers for the giant kelp Macrocystis pyrifera
Conservation Genetics, 2009We report the isolation and characterization of 16 microsatellite loci to study the population genetics of the giant kelp, Macrocystis pyrifera. Markers were obtained by screening a genomic library enriched for microsatellite motifs. Of the 37 primer pairs defined, 16 amplified clean polymorphic microsatellites and are described.

Translocation in the Giant Kelp Macrocystis
Science, 1963Experiments with C 14 -labeled bicarbonate demonstrate that organic products of photosynthesis are transported through the stipe tissue of Macrocystis . Depending upon conditions, not all of which have been fully ascertained, the direction of transport may be either predominantly apical or ...

Isolation and characterization of the chloroplast DNA of Macrocystis integrifolia
Hydrobiologia, 1984Extensive nucleotide sequence diversity has been demonstrated in the mitochondrial DNA of rodents and other animals (Lansman et al. 1981). Such data have provided information concerning the phylogenetic relatedness of conspecific populations. We wanted to apply a similar analysis to the chloroplast DNA (ctDNA) of the kelps.

Influences of macronutrients and water temperatures on summertime survival of Macrocystis canopies
Hydrobiologia, 1984 Macrocystis does not occur in tropical waters (Womersley 1954) and kelp canopies in southern and Baja California frequently deteriorate or disappear during warm summers (Brandt 1923; Clendenning & Sargent 1971).

Interspecific hybridization of the species of Macrocystis in California
Aquaculture, 1986Abstract Three species of Macrocystis occur in California: M. pyrifera, M. angustifolia and M. integrifolia . Gametophytes isolated from them were grown in the laboratory. Male and female gametophytes were crossed in the laboratory in all possible combinations.

Macrocystis and its environment, knowns and unknowns
Aquatic Botany, 1986Abstract Macrocystis commonly dominates substantial expanses of the nearshore along coasts where it occurs. We discuss several physiological and ecological factors affecting Macrocystis populations, particularly as they may influence competition with other seaweed species.

CHELATED IRON AND GAMETOGENESIS IN MACROCYSTIS
Journal of Phycology, 2001Stekoll, M. S.Juneau Center for Fisheries and Ocean Sciences, University of Alaska, Juneau, AK 99801 USAGametophytes of Macrocystis can be vegetatively propagated indefinitely in the laboratory in media that lacked chelated iron. When clones of vegetatively propagated female gametophytes of Macrocystis pyrifera (L.) C. Ag.

Bioconversion of Macrocystis pyrifera to methane
Journal of Chemical Technology and Biotechnology, 1981AbstractMethane production by anaerobic digestion of kelp is a relatively new approach to augmenting the national gas supply. Digestion of the giant marine kelp Macrocystis pyrifera, investigated in a series of bench‐scale experiments at the Institute of Gas Technology (IGT), is reported.
