Freshwater ecosystems are positioned at low levels in the landscape and receive large inputs of diverse plant-based detritus, a major source of energy for consumers in aquatic ecosystems. We conducted field experiments in Urbana, IL to determine the independent and combined effects of leaves of common tree species including the northern red oak (Quercus rubra L.), sugar maple (Acer saccharum M...

The genus Ramularia includes important plant pathogens with worldwide distribution, commonly associated with leaf spot diseases on a broad range of plant hosts. Although these fungi are common in Iran, most of the species found to date have been identified on the basis of morphological characteristics, and DNA data are available for limited number of them. During our investigation of fungi asso...

The present study was conducted in a Swan river (Main River of district) catchment area of district Una (H.P) to accumulate knowledge regarding diversity of plant resources that are used by local people for medicinal uses and to preserve the traditional way of curing aliments which are losing its importance in young generation. The plant kingdom represents a rich house of organic compound, many...

Thrombocytopenia is a disorder in which there is a thrombocyte count of less than 150×103/μL. Thrombocytopenia is life threatening in many diseases particularly in dengue which is an escalating problem in the world. There was an outbreak of dengue in 2011 in Lahore, Pakistan and it was public opinion that Carica papaya leaf extract helps in recovery of platelet count. The aim of present study w...

BACKGROUND Dendropanax morbifera Léveille has been employed for the treatment of infectious diseases using folk medicine. In this study, we evaluated the antioxidant effects of a leaf extract of Dendropanax morbifera Léveille in the hippocampus of mercury-exposed rats. METHODS Seven-week-old Sprague-Dawley rats received a daily intraperitoneal injection of 5 μg/kg dimethylmercury and/or oral ...

In a previous publication ^ the general situation with respect to the wildfire and the blackfire or angular leaf spot diseases of tobacco (Nicotiana tabacum L.) was discussed and the need for explaining the occurrence of leaf spot epidemics was indicated. It was shown that epidemics of wildfire {Bdcterium tabacum Wolf and Foster) are conditional on the occurrence of leaf water soaking, and the ...

Red leaf blotch is one of the major fungal foliar diseases affecting almond orchards. High-resolution thermal and hyperspectral airborne imagery was acquired from two flights and compared with concurrent field visual evaluations for disease incidence and severity. Canopy temperature and vegetation indices were calculated from thermal and hyperspectral imagery and analyzed for their ability to d...

BACKGROUND Modification of leaf traits in sugar beet requires a strong leaf specific promoter. With such a promoter, expression in taproots can be avoided which may otherwise take away available energy resources for sugar accumulation. RESULTS Suppression Subtractive Hybridization (SSH) was utilized to generate an enriched and equalized cDNA library for leaf expressed genes from sugar beet. F...

Abstract Wheat rusts, including stripe, leaf, and stem are severe wheat diseases cause huge yield loss in China annually. Benefiting from utilizing the genetic resistance varieties, rust has been effectively controlled since 1970s; however, stripe leaf rusts still threating production due to lack of effective agricultural regulations. This review summarizes research advances on physiology, epid...
