\"Cuando<\/p>\n

Un estudio de la Universidad Hebrea <\/b>de Jerusal\u00e9n identific\u00f3 que las plantas <\/b><\/span>redirigen az\u00facares<\/b><\/span> hacia los tejidos heridos<\/b> tras una lesi\u00f3n, un mecanismo que concentra glucosa en la zona da\u00f1ada y ayuda a sostener la reparaci\u00f3n y la <\/b>regeneraci\u00f3n<\/b><\/span>, inform\u00f3 el portal especializado en ciencia Phys.org<\/i>. <\/p>\n

Cuando una planta sufre un da\u00f1o \u2014ya sea por una tormenta, un animal o las tijeras de un jardinero\u2014 enfrenta un desaf\u00edo inmediato: c\u00f3mo llevar suficiente energ\u00eda a la zona herida<\/b> para reconstruir el tejido perdido. El hallazgo aporta una explicaci\u00f3n sobre c\u00f3mo la planta decide d\u00f3nde enviar sus recursos energ\u00e9ticos<\/b>, tanto ante da\u00f1os f\u00edsicos como ante situaciones de estr\u00e9s ambiental.<\/b><\/p>\n

La investigaci\u00f3n, publicada en PNAS,<\/i> tambi\u00e9n identific\u00f3 varios genes <\/b>que participan en el transporte y el metabolismo <\/b>de esos az\u00facares, y observ\u00f3 respuestas gen\u00e9ticas similares en otro tipo de regeneraci\u00f3n. Esa coincidencia, de acuerdo con el portal, sugiere que el mecanismo podr\u00eda actuar en m\u00faltiples formas de reparaci\u00f3n de heridas vegetales<\/b>.<\/p>\n

El trabajo fue dirigido por la estudiante de doctorado Rotem Matosevich<\/b> y el profesor Idan Efroni <\/b>de la Universidad Hebrea. Los investigadores siguieron el movimiento del az\u00facar dentro de plantas vivas con un sensor fluorescente adaptado llamado Glifon<\/b>, que permiti\u00f3 ver en tiempo real d\u00f3nde se acumulaba la glucosa<\/b> a medida que el tejido volv\u00eda a crecer.<\/p>\n

\"La<\/p>\n

De la fotos\u00edntesis a la herida: el recorrido del az\u00facar<\/h2>\n

Para estudiar el proceso, el equipo analiz\u00f3 la regeneraci\u00f3n de ra\u00edces en Arabidopsis thaliana<\/b>, una peque\u00f1a planta con flor ampliamente usada en investigaci\u00f3n biol\u00f3gica. Los resultados mostraron que la regeneraci\u00f3n depend\u00eda de los az\u00facares producidos por fotos\u00edntesis <\/b>y que una oferta limitada pod\u00eda ralentizar la reparaci\u00f3n.<\/p>\n

Matosevich resumi\u00f3: \u201cQuer\u00edamos entender no solo si los az\u00facares son necesarios para la regeneraci\u00f3n, sino tambi\u00e9n d\u00f3nde se acumulan y c\u00f3mo se mueven<\/b> a trav\u00e9s de los tejidos da\u00f1ados\u201d.<\/p>\n

El estudio distingui\u00f3 adem\u00e1s el papel de distintos az\u00facares<\/b> tras la lesi\u00f3n. Aunque la regeneraci\u00f3n depend\u00eda de que la sacarosa <\/b>llegara desde tejidos fotosint\u00e9ticos ubicados en otras partes de la planta, la que se acumulaba cerca de la herida era la glucosa<\/b>.<\/p>\n

La raz\u00f3n es que la sacarosa no ingresa directamente a la zona da\u00f1ada sino que se convierte en glucosa en el espacio apopl\u00e1stico<\/b> \u2014la red de paredes celulares y canales por donde circulan sustancias entre c\u00e9lulas\u2014, desde donde las c\u00e9lulas adyacentes a la herida la absorben <\/b>de inmediato. Ese proceso no es una respuesta tard\u00eda: ocurre antes de que comience la reparaci\u00f3n, creando un sumidero proactivo<\/b> que atrae carbohidratos hacia la zona da\u00f1ada.<\/p>\n

Esta acumulaci\u00f3n de glucosa en torno a la herida muestra c\u00f3mo la planta alimenta la reparaci\u00f3n: usa az\u00facares generados por fotos\u00edntesis, los redistribuye despu\u00e9s de la herida y los concentra junto al tejido da\u00f1ado mientras avanza la regeneraci\u00f3n.<\/p>\n

\"Las<\/p>\n

Respuesta gen\u00e9tica: energ\u00eda hacia el tejido da\u00f1ado<\/h2>\n

Experimentos adicionales mostraron que la herida activa con rapidez genes implicados en el transporte y el metabolismo del az\u00facar. Esos genes redirigen recursos energ\u00e9ticos hacia el \u00e1rea afectada<\/b>, en especial cuando el az\u00facar escasea.<\/p>\n

\u201cNuestros resultados sugieren que la lesi\u00f3n va acompa\u00f1ada de un cambio r\u00e1pido y localizado<\/b> en el transporte de az\u00facar<\/b>\u201d, dijo Efroni. \u201cEntender c\u00f3mo las plantas asignan recursos durante la regeneraci\u00f3n puede ayudarnos a comprender mejor c\u00f3mo se coordinan el crecimiento y la reparaci\u00f3n<\/b>\u201d.<\/p>\n

Los autores, conforme al portal, plantean que estos resultados podr\u00edan ayudar a entender c\u00f3mo los cultivos <\/b>se recuperan de da\u00f1os f\u00edsicos <\/b>causados por viento, granizo, plagas, maquinaria agr\u00edcola o podas de rutina. Tambi\u00e9n podr\u00edan aportar informaci\u00f3n sobre la respuesta de las plantas a sequ\u00eda, calor o suelos pobres<\/b>, situaciones en las que los recursos energ\u00e9ticos se vuelven limitados.<\/p>\n

Adem\u00e1s del hallazgo biol\u00f3gico, el estudio present\u00f3 una herramienta para visualizar c\u00f3mo se mueven los az\u00facares<\/b> en plantas vivas. Los investigadores sostienen que ese m\u00e9todo podr\u00eda servir en trabajos futuros para examinar c\u00f3mo las plantas distribuyen energ\u00eda<\/b> durante el crecimiento, el estr\u00e9s y la recuperaci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
