Mad honey poisoning which is induced by Grayanotoxin (Andromedotoxin), is also known to have adverse effects in the cardiovascular system leading to different clinical entities. This toxin is produced by a member of the Rhododendron genus of plants of two R. Luteum and R. Panticum. In this article, we presented a case of slow ventricular response atrial fibrillation complaints with nausea, vomi...

Four evergreen broadleaf Rhododendron spp. (Rhododendrons), namely, aganniphum, R. nyingchiense, wardii, and triflorum, occur in harsh subalpine habitats the southwest Qinghai-Tibet Plateau (QTP), China. Considering that four Rhododendrons cannot escape their unique environment, they must evolve a set of adaptations to survive, but information is lacking. To uncover physiological adaptation cha...

Infection of compatible plants by Phytophthora spp. often leads to a decline in stomatal conductance and photosynthesis, although the mechanistic basis for such declines is not completely understood. In many cases, declines in leaf gas exchange rates have been linked to losses in water supply capacity associated with root and/or xylem. However, the reductions in gas exchange may not be proporti...

Ploidy level was determined for six species and 88 cultivars of the Rhododendron subgenus Tsutsusi. High-resolution flow cytometry of nuclear DNA was performed on macerated plant tissue. All plants analyzed were diploid (2n = 26) with the exception of ‘Euratom’, ‘Euratom Orange’, and ‘Red Wing’, which were triploid (3n = 39), and ‘Casablanca Tetra’, which was found to be a cytochimera: mixoploi...

• Climate and land use change were used to model habitat suitability of Rhododendron. Land climate interaction may the invasiveness South-western north-eastern Wales experience R. ponticum invasion by 2030. The study demonstrates significance using policy-driven projections. Global drivers such as changes are known interact in their effects on biodiversity. impact these global biodiversity is i...
