Root border cells (RBC) formerly called dead sloughed root cap cells are live cells released to soil by the growing root from the outermost cap layer. They differ from root tip cells in morphology, pattern of synthesized proteins and function. The number of RBC produced by a given root during a 24-h period is conserved at the family level. Production and RBC release from the root cap is controlled by endo- genous signals and many environmental factors. Metabolites synthesized by RBC released from the root cap and exported from cells include polysaccharides which facilitate penetration of the soil by the cap, proteins (enzymes and biocides), factors controlling plant and microbial cell division, and attractants for bacteria, fungi and nematodes. The above-mentioned properties of RBC indicate that they are a significant factor affecting the composition and structure of the rhizospheric microbial community and also are involved directly or indirectly in interaction between plants and soil microorganisms.
