Plasmid pIPO2 is a cryptic, conjugative, broad-host-range plasmid isolated from the wheat rhizosphere. It efficiently self-transfers between alpha, beta and gamma Proteobacteria and has a mobilizing/retromobilizing capacity for IncQ plasmids. The complete nucleotide sequence of pIPO2 is presented on the basis of its mini-Tn5::luxABtet-tagged derivative, pIPO2T. The pIPO2 sequence is 39815 bp lo...

Studies have been made of the digestion of nitrogen (N) and of organic matter (OM) in sheep offered thirteen gramineous roughages of widely differing nutritive value. It was concluded that the true digestibility of crude protein in the intestines ranged from 74 to 82% (mean 78%). These estimates were based on observations that, while metabolic faecal N (MFN) was equal to 0.4 g/100 g OM intake, ...

Abstract Nowadays due of the world population growth, demand for agricultural products is also growing. To obtain good meat and dairy products, high-quality feed farm animals necessary. Legume-gramineous perennial grass mixtures are used to improve fodder lands. Our experience included a test 9 variants legume-gramineous mixtures, where 6 types grasses were used: red clover, alfalfa (legumes), ...

This work proposes an approach based on the difference of local fractal dimension (DLFD) for seed identification of gramineous grass, rather than shape and color of the seeds. Being an important forge category of grassland, gramineous grass has been rarely investigated for the automated identification task by the researchers. Three main steps are involved in the extraction of DLFD. At first, th...

Silicon (Si) uptake has been extensively examined in rice (Oryza sativa), but it is poorly understood in other gramineous crops. We identified Low Silicon Rice 2 (Lsi2)-like Si efflux transporters from two important gramineous crops: maize (Zea mays) and barley (Hordeum vulgare). Both maize and barley Lsi2 expressed in Xenopus laevis oocytes showed Si efflux transport activity. Furthermore, bar...

Among the agricultural practices promoted by Common Agricultural Policy to increase soil functions, use of cover crops is a recommended tool improve sustainability Mediterranean woody such as olive orchards. However, there broad range crop typologies in relation its implementation, control and species composition. In that sense, influence different plant on quality indicators orchards remains u...

A new species of the genus Pristimantis is described from Churi tepui, in the Chimanta massif, Estado Bolivar, Venezuela. The new species was discovered during the Muchimuk Expedition 2009, an ongoing speleological exploration of the Charles Brewer cave system, the largest sandstone cave on Earth. The species is known from only one female, collected near the mouth of the Muchimuk cave, in "non-...
