Ephemeral rivers act as linear oases in drylands providing key resources to people and wildlife. However, not much is known about these rivers' sensitivities to human activities. We investigated the landscape-level determinants of riparian tree dieback along the Swakop River, a dammed ephemeral river in Namibia, focusing on the native ana tree (Faidherbia albida) and the invasive mesquite (Pros...

UNLABELLED The protein-protein interactions between viral and host proteins play an essential role in plant virus infection and host defense. The potyviral nuclear inclusion protein a protease (NIa-Pro) is involved in various steps of viral infection. In this study, the host proteins interacting with papaya ringspot virus (PRSV) NIa-Pro were screened in a Carica papaya L. plant cDNA library usi...

The aim of present study is to investigate neuroprotective and nootropic activity of Petroleum Ether Extract of Carica papaya seeds (PEECPS) on diabetic induced cognitive decline rats. Rectangular maze and morris water maze models were used to evaluate nootropic activity and neuroprotective effects were studied by estimating acetyl cholinesterase (AchE), malondialdehyde (MDA), superoxide dismut...

Oak decline and related mortality have periodically plagued upland oak-hickory forests, particularly oak species in the red oak group, across the Ozark Highlands of Missouri, Arkansas and Oklahoma since the late 1970s. Advanced tree age and periodic drought, as well as Armillaria root fungi and oak borer attack are believed to contribute to oak decline and mortality. Declining trees first show ...

Dengue Fever (DF), a type of viral disease, is now almost an endemic to certain tropical and subtropical regions of the world. (Kadir et al., 2013; Senthilvel et al., 2013; Pigili et al., 2014; Abrao et al., 2015). According to Dengue Situation Update (Number 474) by World Health Organization, as on September 12, 2015, there were 85,488 dengue cases with 234 deaths reported in Malaysia for the ...

Papaya (Carica papaya L.) is one of the most economically, medicinally and nutritionally important tropical fruit crops. Expressed sequence tags (ESTs) derived simple sequence repeat (SSR) markers are more valuable as they are derived from conserved genic portion. Development of EST-SSRs markers through in silico approach is cheaper, less time consuming and labour-intensive. In this study, we a...

background: the aims of the study are to determine the radioactivity concentrations of 226ra, 238u, 232th and 40k in vegetables of a recently found high background radiation area of south-eastern part of bangladesh and to detect the radiological risks to human from intake of these vegetables. materials and method: 10 plant samples were collected randomly from different locations of the study ar...

We investigated the antiplasmodial properties of crude extracts from Carica papaya leaves to trace the activity through bioassay-guided fractionation. The greatest antiplasmodial activity was observed in the ethyl acetate crude extract. C. papaya showed a high selectivity for P. falciparum against CHO cells with a selectivity index of 249.25 and 185.37 in the chloroquine-sensitive D10 and chlor...

Dieback in strawberry (Seolhyang cultivar) was first observed during the nursery season (June to September) in the Nonsan area of Korea in the years 2012 and 2013. Initial disease symptoms included dieback on runners, as well as black rot on roots, followed by wilting and eventually blackened, necrotic discoloration in the crowns of daughter plants. A fungus isolated from the diseased roots, ru...

A high-density genetic map of papaya (Carica papaya L.) was constructed using 54 F(2) plants derived from cultivars Kapoho and SunUp with 1501 markers, including 1498 amplified fragment length polymorphism (AFLP) markers, the papaya ringspot virus coat protein marker, morphological sex type, and fruit flesh color. These markers were mapped into 12 linkage groups at a LOD score of 5.0 and recomb...
