BACKGROUND Rhododendron leaf extracts were previously found to exert antimicrobial activities against a range of Gram-positive bacteria. In this study, we investigated which of the extracts with these antimicrobial properties would be best suited for further exploitation. Specifically, the project aims to identify biologically active compounds that affect bacterial but not mammalian cells when ...

Pine needles are one of the most commonly used bioindicators of polycyclic aromatic hydrocarbons (PAHs) in the environment. Therefore, the main objective of the current research was the assessment of PAHs accumulation potential of Scots pine (Pinus sylvestris L.) needles in comparison to wild rosemary (Rhododendron tomentosum Harmaja) and birch (Betula spp.) leaves. Our study was carried out on...

Understanding changes in community composition caused by invasive species is critical for predicting effects on ecosystem function, particularly when the invasive threatens a foundation species. Here we focus on dynamics of forest structure, composition and microclimate, and how these interact in southern Appalachian riparian forests following invasion by hemlock woolly adelgid, HWA, Adelges ts...

Isolation of more than 200 strains of endophytic fungi from the roots of several host plants belonging to order Ericales (Vaccinium, Calluna, Rhododendron, Empetrum, etc.) was followed by a successful attempt to verify ericoid mycorrhiza status of some of these fungal isolates under axenic conditions. In two screening experiments, the most efficient ericoid mycorrhiza fungal strains were found ...

Rhododendron arboreum is an evergreen shrub or small tree with a showy display of bright red flowers. The name ‘RHODODENDRON’ is derived from the Greek word ‘RHODO’ means rose & ‘DENDRON’ means tree. Rhododendron is the national flower of Nepal & is known as (Laligurans) & the state tree of Uttarakhand. It is called ‘Burans, Bras, Buras or Barahke-phool’ in local dialect. It is widely popular f...

Azalea is a general designation of Rhododendron in the Ericaceae family. not only has high ornamental value but also application ecological protection, medicine, and scientific research. In this study, we used Illumina PacBio sequencing to assemble annotate entire chloroplast genomes (cp genomes) four species. The R. concinnum, henanense subsp. lingbaoense, micranthum, simsii were assembled int...

Rhododendron arboretum is a woody plant with gaudy showcase of dazzling red blossoms has place Ericaceae typically develops on North Temperate Zone particularly in the sodden corrosive soil Himalayas, South East Asia. The tracked down Himalayas from Jammu & Kashmir eastwards to Nagaland and generally fills Bhutan, China, Myanmar, Nepal, Sri Lanka, Pakistan Thailand. Usually it utilized gardens,...

We report a case of severe poisoning in a 57-day-old infant who presented with vomiting, convulsions, and shock after ingesting a bottle of milk containing a decoction of Rhododendron simsii. The grandmother collected this toxic plant from a cultivated area, believing it was good for the airways. Grayanotoxin was detected in both the urine and plant specimens. The infant made a good recovery af...

In 2008 statewide surveys of symptomatic foliage of nursery plants from Tennessee resulted in isolation of 43 isolates of Phytophthora spp. This sample set includes four described species (P. citrophthora, P. citricola, P. nicotianae, P. syringae), and a provisional species of Phytophthora ('P. hydropathica'). At the same time a stream-baiting survey was initiated to recover Phytophthora from e...
