| dc.description | The cultivation of Oryza sativa rice is one of the most important foods in the world. At this time, the demand for rice is expected to increase by 40% by 2030. Demand that could only be satisfied by increasing the current cultivated area, or the colonization of new areas for the production of the crop. This, without incurring the different biotic and abiotic factors that in themselves reduce production. One way to increase production in the same crop area is biotechnology tools. These contribute from the 70s to the present. Genetic improvement produces new improved varieties that contribute to reducing the economic risks of the planted crop. Its benefit is reflected in the environment until it provides adaptability characteristics in soils and environments where the crop does not develop naturally. This bibliographic review work consists of indicating which are the main biotechnological tools, and which is the most used in the genetic improvement of plants. The main biotechnological tools used for the production of O. sativa rice plants are tissue culture, (organogenesis and embryogenesis), transgenic, and cisgenic. These last two propagation tools include genes from outside or within the plant species that contribute to better adaptability of the rice plant to the normal conditions to which they develop, making them tolerant and producing greater productivity. | es_ES |

| dc.description.abstract | El cultivo del arroz Oryza sativa es uno de los alimentos más importantes en todo el mundo. En este momento, se espera que la demanda de arroz aumente un 40% para el año 2030. Demanda que sólo se podría satisfacerse al incrementar el área cultiva actual, o la colonización para nuevas áreas destinas a la producción del cultivo. Esto, sin incurrir en los diferentes factores biótico y abiótico que por si merman la producción. Una forma de incrementar la producción en la misma área de cultivo están las herramientas de biotecnología. Estas contribuyen desde los años 70 hasta la actualidad. El mejoramiento genético logar nuevas variedades mejoradas que contribuyen a disminuir los riesgos económicos del cultivo plantado. Su beneficio se ve reflejado en al ambiente hasta dotar de características de adaptabilidad en suelos y ambiente donde el cultivo no se desarrolla de forma natural. Este trabajo de revisión bibliográfica consiste en indicar cuales son las principales herramientas biotecnológicas, y cuál es la más usadas en el mejoramiento genético de plantas. Las principales herramientas biotecnológicas utilizadas para la producción de plantas de arroz O. sativa están la de cultivo de tejidos, (organogénesis y la embriogénesis) la Trasngénia, la cisgénia. Estas dos últimas herramientas de propagación incluyen genes de fuera o dentro de las especies de la planta que contribuyen a una mejor adaptabilidad de la planta del arroz a las condiciones normales a las que se desarrollan tornándolas tolerantes y produciendo mayor productividad. | es_ES |
