Resumen

Las plagas de áfidos Myzus persicae utilizan pares de proteínas efectoras, Mp1 y Mp58, que interactúan para formar complejos. Estos complejos se unen al anfitrión VPS52, impactando las interacciones entre plantas e insectos y revelando la coevolución dentro de las especies.

Área de la Ciencia:

Las interacciones entre plantas e insectos.
Biología molecular La biología molecular.
La bioquímica es la bioquímica.

Sus antecedentes:

Los agentes patógenos y de plagas manipulan los procesos de las plantas durante la infección.
La mayoría de los estudios se centran en las proteínas efectoras individuales, descuidando las interacciones potenciales.
Nuestro trabajo previo identificó el par de genes vinculados Mp1 y Mp58 en Myzus persicae.

Objetivo del estudio:

Investigar la relación funcional entre los efectores Mp1 y Mp58.
Para determinar si Mp1 y Mp58 interactúan y forman complejos.
Para explorar la conservación evolutiva y la especificidad de la especie de esta interacción.

Principales métodos:

Ensayos de interacción in plant y in vitro.
Análisis de la formación de complejos oligoméricos.
El análisis del ortólogo en Rhopalosiphum padi.
Los ensayos de coinmunoprecipitación identifican socios vinculantes como el VPS52.

Principales resultados:

Mp1 y Mp58 interactúan in planta e in vitro, formando un complejo oligomérico.
Los ortólogos Rp1 y Rp58 de Rhopalosiphum padi también interactúan, pero no entre especies.
El complejo Mp1-Mp58 se une a la proteína 52 asociada a la clasificación de proteínas vacuolares del huésped (VPS52).
El complejo Mp1-Mp58-VPS52 se localiza en estructuras parecidas a vesículas.

Conclusiones:

Los efectores de áfidos pueden formar complejos funcionales, añadiendo complejidad al diálogo molecular planta-insecto.
La coevolución de pares de efectores es específica de la especie, con diversificación entre especies de pulgones.
La comprensión de los complejos efectores es crucial para estudiar las interacciones insecto-planta y los repertorios de efectores.

Protein Complexes with Interchangeable Parts

Protein Complexes with Interchangeable Parts

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Mechanism of Conjugation

Mechanism of Conjugation

Bacterial conjugation is a mechanism of horizontal gene transfer that enables the exchange of genetic material between bacterial cells through direct contact. This process is facilitated by a donor cell carrying a conjugative plasmid, which encodes genes necessary for pilus formation, DNA replication, and transfer. The conjugative plasmid plays a central role in initiating and executing the transfer of genetic material.The tra region of the conjugative plasmid encodes proteins responsible for...

Mechanism of Filopodia Formation

Mechanism of Filopodia Formation

Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

Protein Translocation Machinery on the ER Membrane

Protein Translocation Machinery on the ER Membrane

The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the...

Anaphase Promoting Complex

Anaphase Promoting Complex

The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

Rab Proteins

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
