Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
Plant Tissue Culture02:57

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.
Transgenic Plants02:50

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Types of Genetic Transfer Between Organisms

Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

    Resumen

    La transferencia de genes en los cultivos mejora los rasgos deseables como la resistencia a las enfermedades. La tecnología de ADN recombinante expande las fuentes genéticas para variedades mejoradas de cultivos, combinando métodos tradicionales y modernos para el avance.

    Área de la Ciencia:

    • Genética vegetal y mejora de cultivos.

    Sus antecedentes:

    • La transferencia de genes de plantas tiene una larga historia en la mejora de las variedades de cultivos.
    • Los rasgos como la resistencia a las enfermedades, los insectos y el estrés se transfieren comúnmente de parientes silvestres.

    Objetivo del estudio:

    • Para resaltar el papel de la transferencia génica en la mejora de los cultivos.
    • Discutir el impacto de la tecnología de ADN recombinante en la expansión de los recursos genéticos para los cultivos.

    Principales métodos:

    • Utilizando métodos tradicionales para la manipulación genética de plantas.
    • Empleando técnicas de ADN recombinante para la transferencia de genes.

    Principales resultados:

    • Los métodos de ADN recombinante amplían significativamente el alcance de los recursos genéticos disponibles para la mejora de cultivos, que se extiende más allá del reino vegetal.
