Specification of the borders of central gap gene expression mediated largely by the effects of other gap genes; in insects this is exemplified by knirps repression of Kruppel. The regionalization process that specifies organ primordium boundaries resulting in a restriction of organogenesis to a limited spatial domain and keeping the organ separate from surrounding tissues. Specification of the borders of terminal gap gene expression mediated largely by the effects of other gap genes. The process by which the limits of an anatomical structure are generated. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The process that gives rise to a rhombomere boundary. This process pertains to the initial formation of a boundary delimiting a rhombomere. Rhombomeres are transverse segments of the developing rhombencephalon that are lineage restricted, express different genes from one another, and adopt different developmental fates. Rhombomeres are numbered in anterior to posterior order. Specification of the borders of posterior gap gene expression mediated largely by the effects of other gap genes; in insects this is exemplified by hunchback and tailless repression of knirps. The formation and development of the equator that forms the boundary between the photoreceptors in the dorsal sector of the eye and those in the ventral sector, dividing the eye into dorsal and ventral halves. The process by which anatomical structures are generated and organized. Morphogenesis pertains to the creation of form. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. Formation of a lineage restriction boundary within a developing tissue which does not correspond to some morphological barrier. The process whose specific outcome is the formation of the hindbrain-spinal cord boundary. The formation of the narrow stripe of cells that lies between the prospective dorsal and ventral thalami. This boundary contains signals that pattern the prethalamic and thalamic territories of the future mid-diencephalon.
