Thirty-one strains of Rhizobium leguminosarum were screened for their ability to fix nitrogen (effectiveness) on lentils (Lens esculenta). Fluorescent antibodies prepared against four of the most effective strains (NZP 5400, Hawaii 5-0, Nitragin 128A12, and Nitragin 128C53) and one other effective strain, Nitragin 175P1, were strain specific. NZP 5400, Hawaii 5-0, and Nitragin 128A12 were selec...

Although microbial communities have varying degrees of exposure to environmental stresses such as chemical pollution, little is known on how these communities respond to environmental disturbances and how past disturbance history affects these community-level responses. To comprehensively understand the effect of organophosphorus insecticide application on microbiota in soils with or without in...

The study examined the effects of two methods processing de-hulled sunflower seed meal (SFM) from same batch seeds. Sunflower was fed to broilers as (MSFM) or after it had been pelleted (PSFM) at 75 °C and 360 kPa pressure pass through a 3 mm mesh. Three diets were prepared, namely balancer feed (BF) containing 200 g/kg MSFM PSFM. They 30 pens (two birds each) with male Ross 308 broilers, 8 21 ...

Seed heteromorphism observed in many halophytes is an adaptive phenomenon toward high salinity. However, the relationship between heteromorphic seed germination and germination-related hormones under salt stress remains elusive. To gain an insight into this relationship, the roles of gibberellins (GAs) and abscisic acid (ABA) in regulating germination of Suaeda salsa dimorphic brown and black s...

ified organisms (GMOs) drew thousands of protesters in dozens of countries around the world. The synchronized events were called the March against Monsanto, a reference to the agribusiness company based in St. Louis, Missouri, that has pioneered the crop biotechnology industry. Many GMO opponents view Monsanto as an evil Goliath that is messing with nature, crushing small farmers, and poisoning...

Cytochrome P450 monooxygenases (P450s) are enzymes known to metabolize a wide variety of compounds including insecticides. Their overexpression leading to enhanced insecticide detoxification could result in insecticide resistance in insects. The increased mRNA expression of two P450 genes, CYP6P7 and CYP6AA3, has been previously observed in laboratory-selected deltamethrin-resistant Ano...

Sheep with oesophageal fistulas were used in sham-feeding experiments to assess how sham intakes were affected by (a) physical form of straw (finely and coarsely ground; ground and pelleted), (b) type of food (straw pellets v. lucerne (Medicago sativa) hay pellets) and (c) additions of monosodium glutamate (MSG) with or without NaCl to the various straw diets. Normal animals were also fed on di...
