Drought is the main cause of productivity losses in soybean plants, triggering physiological and biochemical responses, stomatal closure being essential to prevent water losses and thus mitigate the negative effects of drought. Abscisic acid (ABA) is the main molecule involved in stomatal closure under drought conditions along with nitric oxide ( NO). However, the role of NO in this process is not yet fully understood and contrasting findings about its role have been reported.

Water is usually the main limiting factor for soybean productivity worldwide and yet advances in genetic improvement for drought resistance in this crop are still limited. In the present study, we investigated the physiological and molecular responses to drought in two soybean contrasting genotypes, a slow wilting N7001 and a drought sensitive TJS2049 cultivars. Measurements of stomatal conductance, carbon isotope ratios and accumulated dry matter showed that N7001 responds to drought by employing mechanisms resulting in a more efficient water use than TJS2049.

mtDNA Amerindian polymorphisms were studied in 108 inhabitants of Montevideo, Uruguay, using PCR RFLP analysis. Amerindian haplogroups were found in 20.4% of the sample.

We studied HLA DQB1 allele frequencies and the relative risk (RR) of various genotypes in 72 type 1 diabetic patients and 40 control individuals in Uruguay. This is a tri-racial (Caucasian, Black and Indo-American) mixed population. The products of the polymerase chain reaction amplifications were hybridized with oligonucleotides by allele-specific oligonucleotide reverse or dot blot methods.
