The Halogenated Metabolism of Brown Algae (Phaeophyta), Its Biological Importance and Its Environmental Significance
Brown algae represent a major component of littoral and sublittoral zones in temperate and subtropical ecosystems. An essential adaptive feature of this independent eukaryotic lineage is the ability to couple oxidative reactions resulting from exposure to sunlight and air with the halogenations of various substrates, thereby addressing various biotic and abiotic stresses i.e., defense against p...
متن کاملEstimates of nuclear DNA content in 98 species of brown algae (Phaeophyta)
BACKGROUND AND AIMS Brown algae are critical components of marine ecosystems around the world. However, the genome of only one species of the class has so far been sequenced. This contrasts with numerous sequences available for model organisms such as higher plants, flies or worms. The present communication expands our coverage of DNA content information to 98 species of brown algae with a view...
متن کاملChromosome-Numbers in Bromeliaceae
Eighty-three chromosome counts are reported for 72 taxa of the Bromeliaceae. Fifty-eight of these counts are the first known chromosome number reports for their respective taxa. A model of chromosomal evolution in the Bromeliaceae (n = 25) is presented. The model is parsimonious and consistent with existing data on meiotic chromosome numbers within the family and in the closely related Vellozia...
متن کاملChromosome Numbers for Some Erodium L'Hér (Geraniaceae) Species of Iran
Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...
متن کاملThe shading effects of Dictyota sp . algae ( Dictyotales , Phaeophyta ) on Acropora aspera coral on the Heron Island reef flat
A major threat to coral reefs today is the phase shift to algaldominated reefs. Algae can stress corals by overgrowing and smothering them, blocking sunlight needed for photosynthesis, and enhancing microbial growth. However, the mechanisms underlying algae-coral interactions are still poorly understood. This study examined how the tumbleweed algae Dictyota sp. affects the photophysiology of th...
