RESUMEN

La importancia de las pectinas en diversos procesos del desarrollo vegetal ha sido ampliamente estudiada recientemente. Las características de la pared celular, tal como rigidez o relajación, dependen en gran medida del grado de metil esterificación de las pectinas. En particular, los constantes cambios estructurales de uno de los componentes de la pectinas, los homogalacturonanos, a consecuencia de la actividad de pectin metil esterasas y poligalacturonasas y de las proteínas que inhiben estas enzimas, generan cambios locales en las características mecánicas de la pared celular que son fundamentales para el desarrollo vegetal. Estos procesos han sido ampliamente descritos durante el crecimiento del polen y en la formación de primordios en el meristemo apical de Arabidopsis thaliana.
