Phloem specialisation
Webb26 okt. 2024 · Also referred to as cell differentiation, cell specialization is the process wherein “ general ” or “ common ” cells evolve to form specific cells that have specific functions. This process is very much prevalent and most important during embryological development. During adulthood, cells called stem cells become specialized to replace ... WebbWe found that cellular specification is mediated near the stem cell niche by PHLOEM EARLY DOF (PEAR) transcription factors. However, the PEAR dependent differentiation …

Webb28 mars 2024 · Phloem is the other type of transport tissue; it transports sucrose and other nutrients throughout the plant. Xylem and phloem give vascular plants their classification; they are the vascular tissues that transport substances throughout the plant. Function of … WebbThe mechanisms that allow cells in the plant meristem to coordinate tissue-wide maturation gradients with specialized cell networks are critical for indeterminate growth. Here, we reconstructed the protophloem developmental trajectory of 19 cells from cell birth to terminal differentiation at single cell resolution in the Arabidopsis root.
