En este artículo se pretende de forma muy general explicar qué es una planta transgénica, cómo se construye, es decir, que pasos hay que dar hasta obtenerla y qué aplicaciones tienen. Veremos, entre otras, aplicaciones agrícolas, como la producción de plantas resistentes a herbicidas, y aplicaciones industriales como la producción de vacunas u otros compuestos de interés terapéutico. Finalmente analizaremos alguno de los aspectos polémicos y el rechazo que la construcción de plantas transgénicas ha generado.

Pectin is a collection of polysaccharides, which play an important role in controlling the pore size of the plant cell wall, regulating cell-cell adhesion, and providing a source of signalling molecules that elicit a range of cellular responses. Apart from this, pectins are of interest because they are an attractive hydrocolloid for various food applications. The kind and distribution of decorative groups in the pectic molecules largely determines for which application a particular pectin is most suitable. After the extraction of starch from potato tubers, a by-product is obtained, which is relatively rich in pectin. However, the quality of these pectins is poor compared to that from other sources such as citrus and apple. Rather than trying to change the structural cha.racteristics of potato pectin post-harvest, we have embarked on achieving this in the potato plant itself. This paper summarises the structural features of pectin, the distribution of various peetic epitopes in tuber cell walls, the enzymes involved in its biosynthesis and degradation, and strategies employed to alter its fine structure in planta.
