The process whose specific outcome is the progression of the sinoatrial (SA) node over time, from its formation to the mature structure. The SA node is part of the cardiac conduction system that controls the timing of heart muscle contraction. It relays electrical signals to the AV node.

The series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway is induced by the cell cycle regulator phosphoprotein p53, or an equivalent protein, in response to the detection of DNA damage, and ends when the execution phase of apoptosis is triggered.

The process whose specific outcome is the progression of the atrioventricular (AV) node over time, from its formation to the mature structure. The AV node is part of the cardiac conduction system that controls the timing of ventricle contraction by receiving electrical signals from the sinoatrial (SA) node and relaying them to the His-Purkinje system.

The process whose specific outcome is the progression of the cardiac conduction system over time, from its formation to the mature structure. The cardiac conduction system consists of specialized cardiomyocytes that regulate the frequency of heart beat.

The process in which the anatomical structure of the endocardium is generated and organized. The endocardium is an anatomical structure comprised of an endothelium and an extracellular matrix that forms the innermost layer of tissue of the heart, and lines the heart chambers.

OBSOLETE. The series of events required to receive a stimulus indicating DNA damage has occurred and convert it to a molecular signal.

Catalysis of the hydroxylation of an ecdysteroid at carbon position 2.

Catalysis of the hydroxylation of an ecdysteroid at carbon position 22.

OBSOLETE. The movement of nucleosomes along a DNA fragment.

An enzyme complex which in humans and yeast consists of at least five proteins; for example, the complex contains GAA1, GPI8, PIG-S, PIG-U, and PIG-T in human, and Gaa1p, Gab1p, Gpi8p, Gpi16p, and Gpi17p in yeast. Catalyzes the posttranslational attachment of the carboxy-terminus of a precursor protein to a GPI-anchor.

An immature spore undergoing development. The spore usually consists of nucleic acid, prospore membrane(s) that encase the nucleic acid, and ultimately a cell wall that covers the membrane(s). This type of spore is observed in ascospore-forming fungi.

A cell or part of the cell that constitutes an early developmental stage of a spore, a small reproductive body that is highly resistant to desiccation and heat and is capable of growing into a new organism, produced especially by certain bacteria, fungi, algae, and nonflowering plants.

The process in which an organism reduces the flow of fluid within its host's vascular system, the vessels and tissue that carry or circulate fluids, such as blood, lymph or sap, through the body of an animal or plant. The host is defined as the larger of the organisms involved in a symbiotic interaction.

OBSOLETE. The responsive adjustment of an organism to the osmotic conditions in or around its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The process in which an organism reduces the flow of fluid within the host xylem, the tissue in plants that carries water and nutrients up from the roots to the shoot and leaves. 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 on, within or near its host organism towards a lower level of a physical stimulus involved in energy generation, such as light, oxygen, and oxidizable substrates. 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 on, within or near its host organism towards a higher level of a physical stimulus involved in energy generation, such as light, oxygen, and oxidizable substrates. 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 the environment of its host organism in response to physical parameters involved in energy generation, such as light, oxygen, and oxidizable substrates. The host is defined as the larger of the organisms involved in a symbiotic interaction.

OBSOLETE. The responsive adjustment of an organism to the pH conditions in or around its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.
