In rice biotechnology advances have been made in genetic transformation, with significant results in breeding elite varieties of japonica and indica subspecies. In order to review the methods and agricultural uses of genetic engineering applied to rice, calves were used several words in English in some of the databases of scientific journals available in the National Libraries National University of Colombia (SINAB), selecting papers published between 2000 and 2011. Based on this initial review, it addition to some articles published at earlier dates, which were considered relevant because they involved significant methodological changes. Since it was able to produce the first transgenic rice plant in the late 80's, several protocols for gene transfer have been used successfully achieving the genetic modification of more than 60 rice cultivars. For this transformation systems have been used both direct and indirect. There have been significant changes in the crop traits such as resistance to biotic (insects, fungi, bacteria, viruses, nematodes), tolerance to abiotic (salinity, drought, high and low temperatures, immersion), improved features agronomic (nutritional quality, yield, nutrient use, herbicide tolerance).

Palavras-chave : Rice; transgenic crops; biotic factor; abiotic factor.
