Any process that stops, prevents or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter [goid 122] [evidence ISS]; The initiation of the activity of the inactive enzyme JUN kinase by phosphorylation by a JUN kinase kinase (JNKK) [goid 7257] [evidence ISS]; The process whose specific outcome is the progression of an embryo from its formation until the end of its embryonic life stage. The end of the embryonic stage is organism-specific. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant [goid 9790] [pmid 8797820] [evidence TAS]; The establishment, maintenance and elaboration of the dorsal/ventral axis [goid 9950] [evidence ISS]; The process whereby relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate [goid 30154] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of Wnt receptor signaling pathway activity [goid 30178] [evidence ISS]; The selective interaction of a transcription factor with specific molecules in the cytoplasm, thereby inhibiting its translocation into the nucleus [goid 42994] [pmid 8797820] [evidence TAS]; Any process that stops, prevents or reduces the frequency, rate or extent of DNA binding, selective interaction with deoxyribonucleic acid [goid 43392] [evidence ISS]
