We reviewed the conservation status of rare and endangered species of mussels in southeastern Oklahoma by completing surveys of 10 long-term monitoring sites on the Kiamichi River and five sites in the Little River. We found extant populations of the Ouachita rock pocketbook, Arkansia wheeleri, scaleshell, Leptodea leptodon, winged mapleleaf, Quadrula fragosa, and rabbitsfoot, Quadrula cylindri...

Marine algae are significant ingredients to formulate drugs for treating disease as they possess various bioactive potentials. Different marine algae (Laurencia papillosa and cylindrica (red algae) were collected from Red Sea (Faied and Ein Al-SokhnaSuez). Ulva fasciata (green algae) was collected from the Mediterranean Sea (Abu-Qir near Alexandria) and Dilophus fasciola (brown algae) was colle...

ABSTRACT Although the isolated effects of cyanobacteria Anabaena cylindrica and bacteria Azospirillum brasilense are well-known, co-inoculation both can promote other benefits to corn plants’ biological nitrogen fixation growth. The aim was evaluate initial growth chloroplast pigment levels hybrids co-inoculated with A. cylindrica. experiment conducted in greenhouse conditions using completely ...

14C 0 2 Fixation, Effect of Iodoacetamide, Glycolate Metabolism, Anabaena The cyanobacterium Anabaena cylindrica grown in a nitrogen free medium at + 25 °C was used for short-term 1 4C-kinetics experiments under different conditions. During the dark/light transients the initial fixation products were mainly sugar monophosphates and 3-phosphoglyceric acid (Calvin cycle intermediates), aspartate ...

The genetic diversity and differentiation of three Chinese Bruguiera gymnorrhiza populations was examined in this study: Expected heterozygosity at species and population levels was 0.293 and 0.268, observed heterozygosity was 0.2745 and 0.2705, respectively. The genetic diversity between populations was 0.0830, which showed that among total heterozygosity, 8.3% came from inter-population. Gene...

A catecholate siderophore - anachelin - has been isolated from the cyanobacterium Anabaena cylindrica CCAP 1403/2A. The central part of the siderophore is a tripeptide consisting of L-Thr, D-Ser and L-Ser. Its C-terminus is linked amidically to a 1,1-dimethyl-3-amino-1,2,3,4-tetrahydro-7,8-dihydroxyquinolinium system and its N-terminus to 6-amino-3,5,7-trihydroxyheptanoic acid. The 7-hydroxyl g...

Studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. Chromosome staining of immature and adult pollen grains through conventional acetocarmine procedure is tedious and often leads to unsatisfactory results. An acetocarmine stain, used in conjugation with Carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike be...

Sequencing was used to investigate the origin of the D genome of the allopolyploid species Triticum aestivum and Aegilops cylindrica. A 247-bp region of the wheat D-genome Xwye838 locus, encoding ADP-glucopyrophosphorylase, and a 326-bp region of the wheat D-genome Gss locus, encoding granule-bound starch synthase, were sequenced in a total 564 lines of hexaploid wheat (T. aestivum, genome AABB...
