Nutritionally induced changes in endosperm of shrunken-1 and brittle-2 maize kernels grown in vitro
(Crop Science, 1996-07-01) [Artigo]
Although mineral nutrition affects maize (Zea mays L.) yield by controlling starch deposition in kernels, the mechanisms involved are largely unknown. Our objectives were to examine this relationship by nutritionally and ...
Effect of acute heat stress on heat shock protein 70 messenger RNA and on heat shock protein expression in the liver of broilers
(British Poultry Science, 1996-05-01) [Artigo]
1. The synthesis of heat shock protein 70 (Hsp70) mRNA and the expression of Hsp70 in the liver of broiler chickens submitted to acute heat stress (35 degrees C for 5 h) was investigated.2. Hsp70 expression was detected ...
Use of lipopolysaccharides to characterize Bradyrhizobium spp.
(Soil Biology and Biochemistry, 1996-09-01) [Artigo]
Three methods of extraction of lipopolysaccharide (LPS) were compared-the conventional hot phenol-water method with 40% phenol, a modified form of this method using 10% phenol, and the hot saline method. Good recovery of ...
