    Abstract/Description
    En este artículo se revisa el estado del conocimiento sobre el metabolismo del almidón en las plantas superiores y específicamente los mecanis­mos de control y regulación de las rutas de síntesis y degradación. Se considera que para obtener almidones, mediante manipulación genética, es necesario conocer los mecanismos bioquímicos que intervienen en la formación del gránulo de almidón y las enzimas participantes. Se discuten los mecanismos de la regulación hormonal y circadiana de los azúcares y la genética individual de las principales enzimas implicadas. Se revisan en particular los métodos empleados en la caracterización bioquímica y fisico química y el estado del conocimiento actual de la producción de almidones modificados. = Regulation of starch biosynthesis in higher land plants: new avenues for modifying starch. This article reviews current knowledge of starch metabolism in higher plants, and especially the control and regulation of the biosynthetic and degradative pathways. The possibility of designing starches for industrial uses by genetic manipulation requires understanding of the biochemical mechanism of starch granule formation and the control of enzymes and protein complexes. The regulation by hormones, sugars and circadian rhythms is discussed as well as the genetic of key enzymes of this pathway. In particular, the review focuses on the methods for biochemical and physiochemical starch and production of modified starches.
