Plasmodesmata (PDs) are microscopic channels that connect virtually every plant cell to its neighbors. They also provide a route for molecules to access the phloem for systemic movement throughout the plant. In this report, I review recent findings that broaden the potential impact of these channels, by revealing their contribution to auxin movement and as potential sites of receptor signaling. These discoveries should prompt a reassessment of symplasmic connectivity and its importance to plant development, defense, and physiology.
胞间连丝(PDs)是连接几乎每个植物细胞与其相邻细胞的微观通道。它们还为分子进入韧皮部提供了一条途径,以便在整个植物中进行系统性移动。在本报告中,我回顾了最近的研究发现,这些发现揭示了这些通道对生长素移动的贡献以及作为受体信号传导的潜在位点,从而拓宽了这些通道的潜在影响。这些发现应该促使人们重新评估共质体连接及其对植物发育、防御和生理学的重要性。
