Coral reefs are subject to coral bleaching manifested by the loss of endosymbiotic algae from coral host tissue. Besides algae, corals associate with bacteria. In particular, bacteria residing in the surface mucus layer are thought to mediate coral health, but their role in coral bleaching is unknown. We collected mucus from bleached and healthy Porites lobata colonies in the Persian/Arabian Gu...

In 2016–2021 the ravines floristic diversity of Khinna gorge (Zayamchay river basin, Lesser Caucasus) was studied. is located on right bank Zayamchay river, at foot Gizilja Mount. gorge, 18 species, 13 genera and 11 families plants were found. Plants relict origin also found: Poa nemoralis L., compressa Ulmus glabra Huds., Parietaria chersonensis (Lang & Szov.) Dörfl., Asparagus verticillat...

Competitive interactions shape coral assemblages and govern the dynamics of ecosystems. Although competition is an ecological concept, outcomes competitive are ultimately determined by patterns gene expression. These subject to genotypic variation on both sides any interaction. Such typically treated as “noise”, but it sometimes possible identify within that reveal important hidden factors in e...

The nucleotide sequences of 5S rRNA from two red algae, Gracilaria compressa and Porphyra tenera have been determined. The two 5S rRNAs are fairly dissimilar to each other in their sequences (65% identity), although they are both composed of 121 nucleotides. Their secondary structures are generally of the eukaryotic with a prokaryotic characteristic. Judged from the 5S rRNA sequence data, the r...

Phytochemical investigation of the heartwood of Michelia compressa afforded forty-four compounds, which were identified by comparison of experimental and literature analytical and spectroscopic data. Some compounds were evaluated for their anti-inflammatory and anticancer bioactivities. The result showed that soemerine (1) and cyathisterol (2) exhibited significant nitric oxide (NO) inhibition,...
