The apoplast route for phloem loading occurs when protons are actively transported out of companion cells, creating a proton gradient that allows sucrose co-transport with protons into companion cells.
La ruta apoplástica para la carga del floema ocurre cuando los protones son transportados activamente fuera de las células acompañantes, creando un gradiente de protones que permite la co-transportación de sacarosa con protones hacía las células acompañantes.
