Cell Signaling in Plants01:25

Cell Signaling in Plants

6.1K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Riboswitches01:56

Riboswitches

9.6K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

9.8K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Types of RNA01:23

Types of RNA

72.6K
Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Transcriptional Regulation: Riboswitches01:23

Transcriptional Regulation: Riboswitches

592
Riboswitches are RNA elements that regulate gene expression by altering their secondary structures in response to specific effector molecules. These elements, located in the leader regions of certain mRNAs, act as transcriptional regulators by toggling between alternative conformations to control downstream gene expression. Riboswitch-mediated regulation is a precise mechanism for modulating biosynthetic pathways, as exemplified by the riboflavin biosynthesis pathway in Bacillus...

Translational Regulation01:29

Translational Regulation

544
Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

Area of Science:

  • Plant Biology
  • Molecular Biology
  • Immunology

Background:

  • RNA-binding proteins (RBPs) are crucial regulators of RNA metabolism.
  • RBPs orchestrate post-transcriptional reprogramming during plant immune responses, a process termed 'RBP-mediated immunity'.
  • The study of RBPs in plant immunity is rapidly advancing due to new global profiling and imaging techniques.

Purpose of the Study:

  • To discuss the regulatory roles of RBPs in the RNA lifecycle, focusing on post-transcriptional processes.
  • To explore how RBP functions modulate the plant immunological profile against cellular pathogens.
  • To review RBP-mediated susceptibility and inform crop breeding for disease resistance.

Main Methods:

  • Review of existing literature on specific RBPs and plant immunity.
  • Analysis of insights from global profiling approaches, including protein-RNA interactions, ribosomal profiling, and metabolic profiling.
  • Examination of advanced imaging techniques for RNA and protein localization.

Main Results:

  • RBPs play a central role in plant immune responses by regulating RNA post-transcriptionally.
  • Pathogens can target RBPs, representing a vulnerability in plant defense.
  • Emerging evidence highlights RBP-mediated susceptibility in plants.

  • Knowledge of immune-related RBPs can guide plant breeding strategies.
  • Harnessing RBP regulation can lead to crops with enhanced disease resistance.
  • Understanding RBP-mediated immunity is key to improving plant defense mechanisms.
