Un estudio de investigadores del Centro Nacional de Biotecnolog\u00eda del CSIC indica que \u201cLos mismos genes que se activan ante la falta de nutrientes, inducen el estado durmiente de las yemas en las plantas para detener la formaci\u00f3n de nuevas ramas\u201d.<\/p>\n

El trabajo ha sido publicado en la revista Frontiers in Plant Science, una revista cient\u00edfica revisada por expertos que cubre todos los aspectos de la bot\u00e1nica.\"yemas<\/a><\/p>\n

Seg\u00fan los investigadores, esta respuesta se parece mucho a la de cualquier otra c\u00e9lula animal, vegetal o de levadura que tenga poco az\u00facar disponible. Si hay pocos nutrientes, la c\u00e9lula detiene su crecimiento.<\/p>\n

\u201cEn yemas axilares, esta respuesta gen\u00e9tica ocurre incluso antes de que el az\u00facar sea escaso \u2013explica Pilar Cubas, investigadora del CNB-CSIC y autora principal del trabajo\u2013. Es suficiente que la planta anticipe una situaci\u00f3n en la que sufrir\u00e1 un ayuno de az\u00facar (d\u00edas cortos, mucha luz infrarroja, etc.) para que las yemas entren en modo ahorro y traten de no gastar m\u00e1s de lo estrictamente necesario\u201d.<\/p>\n

Que las yemas de la planta detengan temporalmente su crecimiento permite su supervivencia en casos de escasez de nutrientes, agua o luz, esto ocurre en plantas le\u00f1osas que desde que pierden su follaje en oto\u00f1o no vuelven a brotar hasta primavera.<\/p>\n

Dicho estudio ha contado con la colaboraci\u00f3n de expertos en el desarrollo de plantas y bioinform\u00e1ticos, que han identificado genes comunes que inducen este estado durmiente de las yemas de las diferentes especies.<\/p>\n

\u201cAhora estamos tratando de entender c\u00f3mo se relacionan la percepci\u00f3n de las se\u00f1ales que permiten a las plantas anticipar tiempos de escasez de carbono y energ\u00eda, con las respuestas del modo ahorro que se encienden en la yema axilar en esa situaci\u00f3n\u201d, explica Cubas.<\/p>\n
