The orange box shows a top view of the shoot tip at higher magnification, with the shoot meristem in the center (indicated by the yellow line), surrounded by flower buds of increasing age.

The shoot apical meristem contains multipotent stem cells and produces primordia that develop into all the above ground organs of a plant. Latest Research and Reviews ...

Plants regenerate using pluripotent callus tissues and initiating the de novo formation of shoot apical meristem (SAM). However, the mechanisms governing the efficiency of regeneration are unclear.

The shoot apical meristems are not only tiny, (0.1 to 0.3 mm diameter), but are normally hidden from view by the very young leaves emerging from the base of the meristem.

One microRNA gene, shown in green, is specifically activated by Arabidopsis thaliana Meristem Layer 1 (ATML1) in the outermost layer of a plant shoot apex. This microRNA determines the concentration ...

This process involves the de novo (or new) formation of a shoot apical meristem (SAM) that gives rise to lateral organs, which are key for the plant's reconstruction.
