Any process that activates or increases the frequency, rate or extent of the DNA-dependent transcription of a specific gene or genes. The regionalization process by which the posterior (abdominal) regions of the embryo are specified by the gap genes. The specifically regulated synthesis of RNA from DNA encoding a specific gene or set of genes by RNA polymerase II (Pol II), originating at a Pol II-specific promoter. In addition to RNA polymerase II and the general transcription factors, specific transcription requires one or more specific factors that bind to specific DNA sequences or interact with the general transcription machinery. The specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade. Any process that activates or increases the frequency, rate or extent of transcription from the RNA polymerase II promoter. Any process that increases the frequency, rate or extent of the specifically regulated synthesis of RNA from DNA encoding a specific gene or set of genes by RNA polymerase II (Pol II), originating at a Pol II-specific promoter. The activation of genes encoding transcription factors in the posterior region of an insect embryo by a combination of maternal regulatory signals and interactions among themselves; exemplified by the activation of expression of the Drosophila knirps gene. Any process that modulates the frequency, rate or extent of the specifically regulated synthesis of RNA from DNA encoding a specific gene or set of genes by RNA polymerase II (Pol II), originating at a Pol II-specific promoter. The regionalization process by which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism.
