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 ...

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...

Mycosporine- like amino acids (MAAs) are small (<400Da), colourless, water soluble compounds composed of cyclohexenone or cyclohexinimine chromophere conjugated with the nitrogen substituent of amino acid or its amino alcohol. These compounds are known for their UV- absorbing role in various organisms and seem to have evolutionary significance. The biosynthesis of MAAs is presumed to occur via ...

In this study, 10 species of Bipolaris viz.B. bicolor, B. cynodontis, B. cylindrica, B. hawaiiensis,B. prieskaensis, B. sorghicola, B. sorokiniana,B. spicifera, B. zeae and B. zeicola and four species of Curvularia viz.C. fallax, C. heteropogonicola, C. inaequalis and C. lunata were identified on graminicolous species or soil. Bipolaris cylindrica, B. prieskaensis, B. zeae,C. fallax and C. hete...

Phylogenetic Analysis of Some Indigenous and Non-Indigenous Luffa (Luffa cylindrica) Genotypes using ITS Marker

Most common tumors of the spleen are hematologic and lymphoid malignancies. Non-lymphoid and non-hematologic tumors of the spleen are very rare, the most common of which are vascular tumors. This group of tumors in the spleen is composed of heterogeneous tumors such as hemangioma, angioendothelioma (AE), littoral cell angioma, and angiosarcoma. There are several histologic forms of AE such as e...
