Introducen un gen en cultivos para reducir el uso de insecticidas

Universidad Nacional del Litoral - Facultad de Bioquímica y Ciencias Biológicas

Al alojar un gen de girasol en una planta de experimentación, científicos obtuvieron cultivos que son menos atacados por los insectos. Ese mismo transgén ya había mostrado conferir tolerancia a la sequía.

Stress during Pregnancy and the Expression of Genes

Universidad Nacional de San Martín - Instituto de Investigaciones Biotecnológicas

A research team led by PhD Marcela Brocco studies how the stress suffered by a mother during pregnancy can influence the son’s expression of genes, increasing the probability of having depression or drug abuse tendencies in the future. In an interview with Argentina Investiga the specialist gives details about the research.

Fly’s Heart: Study of its Genes to Treat Cardiac Diseases

Universidad Nacional del Noroeste de la Provincia de Buenos Aires - Escuela de Ciencias Agrarias, Naturales y Ambiantales

The insect’s organ is similar to the human’s. That is why researchers analyze the genes which cause diseases like arrhythmias and heart failure in flies with the objective of going on studying the way to prevent cardiac diseases in humans. “We are the only ones who have analyzed the genetics associated to this fly’s cardiovascular physiology”, remarked one of the researchers.

Yerba mate: Discovery and Characterization of all Its Genes

Universidad Nacional de Misiones - Facultad de Ciencias Exactas, Químicas y Naturales

Researchers from Misiones determined that yerba contains 32,355 genes. The result of the study will permit to know in depth its nutritional properties, antioxidant, antiage and anti-inflammatory effect. It is the first step towards the genome sequencing.

Genes that Regulate Embryonic Development

Rolando Rivera Pomar was awarded a prize in Germany for his scientific work in the area of development genetics. Vinegar fly was his investigation’s axis. In an interview with Argentina Investiga, the specialist considered that “in the last years, the Argentinean scientific system has reached a perception that science and knowledge are important because they contribute to common welfare”.

Dallisgrass: Genome Sequencing of this Argentinean Native Grass

Universidad de Buenos Aires - Facultad de Agronomía

It is a species adapted to different environments, tolerant to excessive humidity and drought. The research also silenced genes like lignin, which could generate big productive improvement, as every percentage unit of reduction of this compound could mean an improvement of 21% in the production of milk or meat.
