Symplastic transport participation of auxins during plant development

The appropriate organogenesis of plants during their life cycle promotes their development and adaptation to different environmental conditions. Various phytohormones regulate plant development but auxin, called Indole-3-Acetic Acid (IAA), is one of the most important. IAA is synthesized in the aeri...

Various phytohormones regulate plant development but auxin, called Indole-3-Acetic Acid (IAA), is one of the most important. IAA is synthesized in the aerial part of plant and is mobilized to the demanding tissues by a rapid transport using the phloem and by the polar auxin transport (PAT). Recently, it has been shown that auxins also are mobilized by a symplastic transport (ST) through plasmodesmata (PD), which opening or closing is regulated by the callose degradation or deposition respectively. The objective of the present work was to deepen the analysis on the participation of symplastic transport of auxins during plant development, as well in the callose degradation or deposition, in the closing or opening of the PD, that regulates the development of some organs of Arabidopsis thaliana. The intervention of PDLP5 proteins is decisive for the callose deposition in the PD, which regulates the auxin distribution and impacts root formation, especially at the lateral roots. The participation of TS is important to develop the auxin activity, which favors root formation, necessary for the improvement plant nutrient absorption. This knowledge can be used to improve development plants of agronomic interest. La apropiada organogénesis de las plantas, durante su ciclo de vida, propicia su desarrollo y la adaptación a diferentes condiciones ambientales. Diversas fitohormonas regulan el desarrollo vegetal, pero la auxina denominada ácido indol-3-acético (AIA) es una de las más importantes. El AIA se sintetiza en la parte aérea de la planta y se moviliza a los tejidos demandantes por un transporte rápido que utiliza el floema y por el transporte polar de auxinas (TPA). Recientemente, se ha demostrado que las auxinas también se movilizan mediante el transporte simplástico (TS) a través de los plasmodesmos (PD), cuya apertura o cierre está regulada respectivamente por la degradación o la deposición de la callosa. El objetivo del presente trabajo fue profundizar en los avances sobre la participación del transporte simplástico de las auxinas durante el desarrollo vegetal, así como la degradación o deposición de la callosa, en el cierre o apertura de los PD, para regular el desarrollo de algunos órganos de Arabidopsis thaliana. La intervención de las proteínas PDLP5 es determinante para la deposición de la callosa en los PD, lo que regula la distribución de la auxina e impacta en la formación radicular, especialmente en las raíces laterales. La participación del TS es importante para desarrollar la actividad de las auxinas, lo cual favorece la formación radicular, necesaria en la mejora de absorción de nutrientes de las plantas. Este conocimiento puede ser utilizado para mejorar las plantas de interés agronómico.
