Plant signal transduction occurs in response to nutrient element deficiency in plant vascular tissue. Recent works have shown that the vascular tissue is a central regulator in plant growth and development by transporting both essential nutritional and long-distance signaling molecules between different parts of the plant's tissues. Split-root and grafting studies have deciphered the importance of plants' shoots in receiving root-derived nutrient starvation signals from the roots. This review assesses recent studies about vascular tissue, integrating local and systemic long-distance signal transduction and the physiological regulation center. A substantial number of studies have shown that the vascular tissue is a key component of root-derived signal transduction networks and is a regulative center involved in plant elementary nutritional deficiency, including nitrogen (N), phosphate (P), and iron (Fe).
植物信号转导发生在植物维管组织对营养元素缺乏的响应过程中。最近的研究表明，维管组织通过在植物组织的不同部分之间运输必需的营养物质和长距离信号分子，成为植物生长和发育的核心调节者。分根和嫁接研究已经阐明了植物地上部分接收来自根部的营养饥饿信号的重要性。本综述评估了关于维管组织的最新研究，整合了局部和系统的长距离信号转导以及生理调节中心。大量研究表明，维管组织是根系衍生信号转导网络的关键组成部分，并且是参与植物基本营养缺乏（包括氮（N）、磷（P）和铁（Fe））的调节中心。
