Differences in the timing of cell death, differentiation and function among three different types of ray parenchyma cells in the hardwood Populus sieboldii × P. grandidentata
2012
Overview
Differences in the timing of cell death, differentiation and function among three different types of ray parenchyma cells in the hardwood Populus sieboldii × P. grandidentata which form uniseriate and homocellular rays were examined and clarified. Ray parenchyma cells died within 5 years, and the disappearance of nuclei from ray parenchyma cells did not occur successively from the pith side, even within individual radial cell lines of a given ray. Cell death occurred earliest in contact cells, which were connected to adjacent vessel elements through pits, in the fourth annual ring from the cambium. Cell death occurred next in intermediate cells, which were located within the same cell lines as contact cells but were not adjacent to vessel elements, in the fourth annual ring from the cambium. Finally, isolation cells, which were located within the other cell lines of a given ray, died in the fifth annual ring from the cambium. Secondary wall thickenings in contact cells and intermediate cells were initiated before those in isolation cells in the current year’s xylem. Most starch grains were localized in intermediate cells, and there were more lipid droplets in contact cells and intermediate cells than in isolation cells. In addition, the largest quantities of protein were found in contact cells. Our results indicate that the position within a ray and neighboring short-lived vessel elements might affect the timing of cell death and differentiation and, thus, the function of long-lived ray parenchyma cells in Populus sieboldii × P. grandidentata.
