Because excised, washed roots of rice (Oryza sativa) immediately produce CH4 when they are incubated under anoxic conditions (P. Frenzel and U. Bosse, FEMS Microbiol. Ecol. 21:25-36, 1996), we employed a culture-independent molecular approach to identify the methanogenic microbial community present on roots of rice plants. Archaeal small-subunit rRNA-encoding genes were amplified directly from ...

The root hemiparasite witchweed (Striga spp.) is a devastating agricultural pest that causes losses of up to $1 billion US annually in sub-Saharan Africa. Development of resistant crops is one of the cost-effective ways to address this problem. However, the molecular mechanisms underlying resistance are not well understood. To understand molecular events upon Striga spp. infection, we conducted...

Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is an economically important pest of variety crops, including maize (Zea mays L.), rice (Oryza sativa and cotton (Gossypium spp.). Conventional chemical insecticides are usually used for management this pest; however, a viable alternative the use microbial agents or their biological products, such as entomopathogenic nematodes. Their e...

Nowadays, Alzheimer's disease is the most prevalent epiphenomenon of the aging population. Although soluble amyloid-β (Aβ) species (monomers, oligomers) are recognized triggers of the disease, no therapeutic approach is able to stop it. Herbal medicines are used to treat different diseases in many regions of the world. On the Balkan Peninsula, at the eastern Mediterranean Sea, and adjacent regi...

The present study deals two new alpheid shrimp species from the transisthmian Salmoneus ortmanni (Rankin, 1898) complex. Salmoneus alvarezi sp. nov. is described based on materials collected in Bahía Málaga, Colombia, and Punta Morales, Costa Rica, and is closely related to the western Atlantic S. ortmanni and S. wehrtmanni Anker, 2011. Salmoneus malagensis sp. nov. is described based on specim...

Strategic application of moxidectin pour-on (Cydectin) was evaluated in Uganda for its effect on pasture larval counts and gastrointestinal nematode faecal egg counts in village cattle kept under tethering (semi-intensive) grazing management. The strategic deworming schedule involved treating cattle twice at an interval of 2 months, at the end of the 1st wet season and during the 2nd wet season...

A draft genome for Corynebacterium afermentans LCDC 88-0199(T) was investigated. The size of the genome was 2,345,615 bp with an observed G+C content of 64.85%. Annotation revealed 2 rRNA sequences, 54 tRNA genes, and 2,164 coding sequences. Genome coverage was 85× and consisted of 24 contigs with an N50 of 187,988 bp.
