• The main difference between these two types of meristem, apart from the obvious disparity between the objective organ, is the verticillate (or whorled) phyllotaxis, that is, the absence of stem elongation among the successive whorls or verticils of the primordium.
• Genes including STM (shoot meristemless) and CUC (cup-shaped cotyledon) are involved in defining the borders of the newly formed primordium.
• Pistil primordium differentiation stage: The pistil primordia beginning to differentiate is indicated by the multiple round bulges in the upper region of the meristem.
• In the mouse gonadal primordium, the genital ridge, which forms from intermediate mesoderm, becomes morphologically distinct at E10.
• However, the situation is more complex, since comparative embryology shows that the length axis of the neural tube (the primordium of the brain) has three internal bending points, namely two ventral bendings at the cervical and cephalic flexures (cervical flexure roughly between the medulla oblongata and the spinal cord, and cephalic flexure between the diencephalon and the midbrain), and a dorsal (pontine or rhombic flexure) at the midst of the hindbrain, behind the cerebellum.
• Tbx4 is specifically expressed in the visceral mesoderm of the lung primordium and governs multiple processes during respiratory tract development such as initial endodermal bud development, respiratory endoderm formation, and septation of the respiratory tract and esophagus.
• The parental cirri are resorbed by the cell during division and the cirri of both daughter cells are produced de novo from cirral anlagen and the oral ciliature of the opisthe daughter cell is generated de novo through the formation of an oral primordium at the posterior end of the cell.
• Anatomical differences start as early as the primordium (immature organ), where the shape of the root cap within primordia differs between belowground crown roots and aboveground brace roots.
