Nitrogenase Activity Associated with Halodule wrightii Roots.
Nitrogen fixation (acetylene reduction) associated with roots of the seagrass Halodule wrightii was measured offshore near Beaufort and Moorhead City, N.C. Rates of acetylene reduction were higher in aerobic than in anaerobic assays and were linear for up to 5 days. The temperature range for acetylene reduction was 15 to 35 degrees C with a maximum activity at 35 degrees C. Nitrogenase activity...
متن کاملVariations in leaf soluble amino acids and ammonium content in subtropical seagrasses related to salinity stress.
A survey of leaf soluble amino acids was conducted for four subtropical seagrasses grown at several salinities. Proline functioned as an organic osmoticum in Halodule wrightii Aschers., Thallasia testudinum Banks ex Koenig, and Ruppia maritima L., while alanine functioned in an osmoregulatory capacity in Halophila engelmanni Aschers. When light-and salinity-induced variations in leaf NH(4) and ...
متن کاملAssessment of the Impact of Increased Solar-Ultraviolet Radiation of Seagress
An early concern in the planning of the Space Shuttle Program was the loss of at mospheric ozone due to repeated Shuttle flights and a resultant increase in penetrant ultraviolet radiation. Our research group has examined the effects of an increase in this radiation (UV-B, 290315 nm) on three marine angiosperms (Halophila engelmannii Aschers, Halodule wrightii Aschers, and Syringodium filiform...
متن کاملFungal endophytes of the seagrasses Halodule wrightii and Thalassia testudinum in the north- central Gulf of Mexico
The purpose of this note is to communicate the diversity of endophytic fungi isolated from living leaves of Halodule wrightii and Thalassia testudinum, two ubiqui tous seagrasses in the northcentral Gulf of Mexico. Fungi were isolated from surfacesterilized leaf fragments of the two plants that had been inoculated onto seawater malt extract agar. Leaves of T. testudinum harbored slightly mor...
متن کاملINFLUENCE OF THE SHOOT DENSITY OF Halodule wrightii ASCHERSON FROM ROCKY AND SANDY HABITATS ON ASSOCIATED MACROALGAL COMMUNITIES
This study evaluated the influence of the shoot density of the shoal grass Halodule wrightii on the composition of the associated algal community, in rocky and sandy habitats on the coast of Ceará in northeastern Brazil. The phycological community included 18 species in 10 families, members of Rodophyta (72.2%), Chlorophyta (22.2%) and Phaeophyceae (5.5%). The largest proportion were epilithic ...
