Resumen
La comprensión del desarrollo de los corales requiere datos completos de expresión génica. Este estudio proporciona un transcriptoma del desarrollo para Acropora millepora y una herramienta interactiva para analizar los cambios en la expresión génica durante el crecimiento y asentamiento de los corales.
Área de la Ciencia:
- Biología Marina
- Biología del Desarrollo
- Genómica
Sus antecedentes:
- Los corales formadores de arrecifes (Scleractinia) son ecológicamente vitales, pero los mecanismos moleculares de su desarrollo son poco conocidos.
- La falta de datos transcriptómicos completos y conjuntos de datos complejos dificultan el análisis del desarrollo de los corales.
Objetivo del estudio:
- Generar un transcriptoma del desarrollo completo para Acropora millepora.
- Desarrollar una herramienta interactiva para visualizar la expresión génica durante el desarrollo de los corales.
Principales métodos:
- Perfil de expresión génica en 26 etapas de la vida de Acropora millepora, desde huevos hasta pólipos juveniles.
- Desarrollo de una herramienta interactiva en línea utilizando R-Shiny para la visualización simultánea de datos de expresión génica a gran escala.
Principales resultados:
- Se observaron cambios transcripcionales importantes durante la gastrulación y la adquisición de competencia.
- La inducción del asentamiento de corales no provocó cambios inmediatos en la expresión génica, pero se produjo una transición significativa de 3 a 6 horas después de la inducción.
Conclusiones:
- El conjunto de datos del transcriptoma del desarrollo y la herramienta de análisis proporcionados tienen como objetivo acelerar la comprensión del desarrollo de los corales.
- Se dispone de una herramienta interactiva en línea para facilitar el análisis de datos de expresión génica de corales.

02:58Properties of Transition Metals
29.8K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

02:31Phase Transitions
23.1K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

01:58Cooperative Allosteric Transitions
8.7K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

02:39Phase Transitions: Vaporization and Condensation
21.2K
The physical form of a substance changes on changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. Vaporization occurs when the thermal motion of the molecules overcome the intermolecular forces, and the molecules (at the surface) escape into the gaseous state. When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules...

02:33Phase Transitions: Sublimation and Deposition
20.1K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

02:39Phase Transitions: Melting and Freezing
15.1K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...
