NADP-dependent glutamate dehydrogenase was partially purified from extracts of the marine siphonous green alga Caulerpa simpliciuscula. The enzyme had an apparent Km NH(4) (+) of 0.4 to 0.7 mm and was highly specific for NADPH, alpha-ketoglutarate, and ammonium ions.The bulk of the NADP-glutamate dehydrogenase was isolated with the chloroplast fraction in cell-free preparations of this alga and...

Effect of Seaweed Liquid Extract (SLE) of Caulerpa scalpelliformis on growth and biochemical constituents of Vigna mungo was studied. The lower concentration of SLE of C. scalpelliformis (25%) enhanced the percentage of germination, shoot length, root length and biochemical constituents viz., chlorophyll, carotenoid, amino acid, reducing sugar and total sugar contents and α-amylase and β-amylas...

Many abundant plants, invertebrates, and seaweed are clonal, and this allows the formation of high-density aggregations, foraging, and the placement of modules into new space, and rapid rates of expansion. For these species, population density and rates of expansion are functions of recruitment of asexual modules and post-recruitment vegetative growth and survivorship. In this study, we provide...

Chromatographic studies have been carried out on cyclea peltata Diels and Cissampelos pareira Linn. The results substantiate that cyclea peltata Diels can be substituted for cissampelos pareira in ayurvedic formulations.

Convergent morphologies have arisen in plants multiple times. In non-vascular and vascular land plants, convergent morphology in the form of roots, stems, and leaves arose. The morphology of some green algae includes an anchoring holdfast, stipe, and leaf-like fronds. Such morphology occurs in the absence of multicellularity in the siphonous algae, which are single cells. Morphogenesis is separ...
