In the magazine Scientific Reports (IF = 4.379) published an article by the staff of the Laboratory of Plant Anatomy on the qualitative and quantitative analysis of the growth of intrusive cambium initials in the Robinia pseudoacacia L. The analysis of cross sections, performed tangential and radial reconstructions of secondary meristematic tissue, as well as measurements of the width of the tissue within which cell remodeling occurs, do not confirm the hypothesis often put forward in the literature that intrusive growth affects the growth of the circumference of the cambium cylinder. The results of the study are in agreement with the statement that symplastic growth (i.e., synchronous, coordinated tissue growth that does not lead to a change in contacts between individual cells) is responsible for the growth of the circumference of the cambium cylinder. Tissue analysis captured the moment of initial status transfer between neighboring cells belonging to the same radial row of cells. An explanation has been proposed that the change in initial cell status may be due to the current arrangement of mechanical stresses in meristematic tissue.
