Agriculture-relevant microorganisms are considered to produce secondary metabolites during processes of competition with other micro- and macro-organisms, symbiosis, parasitism or pathogenesis. Many different strains of the genus Trichoderma, in addition to a direct activity against phytopathogens, are well-known producers of secondary metabolites and compounds that substantially affect the met...

Various field experiments were conducted during the 1997 and 1998 cotton season involving macro and micronutrient fertilization. A total of six experiments were conducted at various locations in Arizona. Each of the field experiments studied the effects of different nutrients and nutrient combinations on both Upland and Pima varieties. The purpose of these experiments were to evaluate Universit...

The ability to use different food sources is likely to be under strong selection if organisms are faced with natural variation in macro-nutrient (protein, carbohydrate and lipid) availabilities. Here, we use experimental evolution to study how variable dietary protein content affects adult body composition and developmental success in Drosophila melanogaster. We reared flies on either a standar...

Recent evidence suggests that establishment of a healthy gut microbiota shortly after birth is important to achieve optimal growth and development of children. Being born into a resource-poor environment presents challenges to the establishment of a healthy gut microbial flora in the newborn. Among these challenges are births that occur at home, traditional pre-lacteal feeding of newborns leadi...

We use the adjoint of a global model of coupled oceanic cycles of carbon, phosphorus and iron to comprehensively and efficiently map the sensitivity of global biological productivity and air-sea carbon fluxes to local perturbations of the atmospheric iron source sustained for a decade or more. Modeled productivity and carbon flux are found to be most sensitive to enhanced iron sources in high n...

The influences of environmental (macro) conditions and those on the cell level are treated from the point of view of heatand mass-transfer in microbial systems. The effects considered are (i) consumption of substrates, (ii) output of products, (iii) production of heat and (iv) aggregation, as far as concerns direct influence on the microenvironment. The other properties which may have indirect ...

Micro-nutrient Fortification of Food T he High-level Expert Forum from FAO’s 192 Member Nations will discuss, deliberate and take important decisions during the World summit scheduled in Rome around the mid November 2009, the strategies to ensure that everyone has enough to eat both today and tomorrow. During last week of October AIIMS New Delhi is organising An International Workshop on Micron...
