OBSOLETE. The movement of a motile cell or organism in response to environmental oxygen on, within or near its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

OBSOLETE. The directed movement of a motile cell or organism in response to a specific chemical concentration gradient on, within or near its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The series of molecular signals generated as a consequence of any member of the BMP (bone morphogenetic protein) family binding to a cell surface receptor that contributes to the determination of lateral mesoderm left/right asymmetry.

Creation of the central hole of the embryonic heart tube by sealing the edges of an epithelial fold.

The chemical reactions and pathways resulting in the formation of a fatty acid which has a chain length greater than C22.

The process in which the anatomical structures of the outflow tract are generated and organized. The outflow tract is the portion of the heart through which blood flows into the arteries.

The process in which the muscular septum is generated and organized. The muscular septum is the lower part of the ventricular septum.

Catalysis of the reaction: S-adenosyl-L-methionine + histone H4 L-lysine (position 20) = S-adenosyl-L-homocysteine + histone H4 N6-methyl-L-lysine (position 20). This reaction is the addition of a methyl group onto lysine at position 20 of the histone H4 protein.

OBSOLETE. Covalent attachment of the ubiquitin-like protein NEDD8 (or equivalent protein) to another protein, as a part of NEDD8-dependant protein catabolism.

The synthesis of transfer RNA (tRNA) from a DNA template by RNA polymerase III (Pol III), originating at a Pol III promoter.

The process in which the membranous septum is generated and organized. The membranous septum is the upper part of ventricular septum.

The process in which the anatomical structures of the outflow tract septum are generated and organized. The outflow tract septum is a partition in the outflow tract.

The characteristic movement of a cell from the dorsal ridge of the neural tube towards the heart and that contributes to heart formation.

The morphogenetic process in which the heart cone is displaced to the left with respect to the vector of the anterior-posterior axis.

The process that gives rise to the embryonic heart tube by the cells of the heart field along a linear axis.

The process that gives rise to the embryonic heart tube. This process pertains to the initial formation of a structure from unspecified parts. The embryonic heart tube is an epithelial tube that will give rise to the mature heart.

The synthesis of small nuclear RNA (snRNA) from a DNA template by RNA Polymerase III (Pol III), originating at a Pol III promoter.

The synthesis of small nuclear RNA (snRNA) from a DNA template by RNA Polymerase II (Pol II), originating at a Pol II promoter.

The process in which the anatomical structures of the cardiogenic plate are generated and organized. The cardiogenic plate is the first recognizable structure derived from the heart field.

The synthesis of ribosomal RNA (rRNA) from a plastid DNA template, usually by a specific plastid RNA polymerase.
