Phylogenetic spectrum and analysis of antibacterial activities of leaf extracts from plants of the genus Rhododendron
BACKGROUND Plants are traditionally used for medicinal treatment of numerous human disorders including infectious diseases caused by microorganisms. Due to the increasing resistance of many pathogens to commonly used antimicrobial agents, there is an urgent need for novel antimicrobial compounds. Plants of the genus Rhododendron belong to the woody representatives of the family Ericaceae, which...
متن کاملProteome dynamics of cold-acclimating Rhododendron species contrasting in their freezing tolerance and thermonasty behavior
To gain a better understanding of cold acclimation in rhododendron and in woody perennials in general, we used the 2D-DIGE technique to analyze the rhododendron proteome during the seasonal development of freezing tolerance. We selected two species varying in their cold acclimation ability as well as their thermonasty response (folding of leaves in response to low temperature). Proteins were ex...
متن کاملIce nucleation activity in various tissues of Rhododendron flower buds: their relevance to extraorgan freezing
Wintering flower buds of cold hardy Rhododendron japonicum cooled slowly to subfreezing temperatures are known to undergo extraorgan freezing, whose mechanisms remain obscure. We revisited this material to demonstrate why bud scales freeze first in spite of their lower water content, why florets remain deeply supercooled and how seasonal adaptive responses occur in regard to extraorgan freezing...
متن کاملA new genus of Macrosiphini Wilson, 1910 (1887) (Hemiptera: Aphididae) from Rhododendron in Turkey.
Rhododendraphis tuatayae gen. n., sp. n. living on Rhododendron sp. (Ericaceae) in Turkey is described based on apterous viviparous females. The new genus is morphologically most similar to Rostratusaphis Fang and Qiao, 2009, but differs in several important characters. Differences between the new genus and other aphid genera with a spinulose second tarsal segment living on Rhododendron spp. wo...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
