Effects of vitamin pre-sowing treatment on sweet maize seedlings irrigated with saline water
Provedor de dados: Acta Agronómica
Autores: Pradi-Vendruscolo,Eduardo; Seleguini,Alexander.
Abstract Salinity stress represents an obstacle for the production of plants of commercial interest, including sweet maize. Among the techniques used to suppress the effects caused by excess salts in the soil is the exogenous application of vitamins. Thus, the objective of this study was to evaluate the effect of the pre-sowing treatment of sweet maize seeds in solutions of thiamine, niacin and these two vitamins combined on the development of the plants irrigated with saline water. The treatments were composed by the 24 h pre-sowing treatment with water, thiamine solution (thiamine 100 mg L-1), niacin solution (niacin 100 mg L-1) and a combined solution with these two vitamins (thiamine 50 mg L-1 + niacin 50 mg L-1) irrigated with saline water. A control...

Vitamin B1 and B6 in the malaria parasite: requisite or dispensable?
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Wrenger,C.; Knöckel,J.; Walter,R.D.; Müller,I.B.
Vitamins are essential compounds mainly involved in acting as enzyme co-factors or in response to oxidative stress. In the last two years it became apparent that apicomplexan parasites are able to generate B vitamers such as vitamin B1 and B6 de novo. The biosynthesis pathways responsible for vitamin generation are considered as drug targets, since both provide a high degree of selectivity due to their absence in the human host. This report updates the current knowledge about vitamin B1 and B6 biosynthesis in malaria and other apicomplexan parasites. Owing to the urgent need for novel antimalarials, the significance of the biosynthesis and salvage of these vitamins is critically discussed in terms of parasite survival and their exploitation for drug...
