AI Article Synopsis

  • The internal modification N(6)-methyladenosine (m(6)A) in plant messenger RNAs was first identified in the 1970s but had fallen out of focus until recent studies revived interest in its significance.
  • New research highlights that mRNA methylation is crucial for normal development in Arabidopsis, showing that many of its mRNAs undergo methylation.
  • The review discusses recent advancements in understanding the epitranscriptome and raises future questions about its role in gene regulation that have not yet been fully explored.

Article Abstract

The most prevalent internal modification of plant messenger RNAs, N(6)-methyladenosine (m(6)A), was first discovered in the 1970s, then largely forgotten. However, the impact of modifications to eukaryote mRNA, collectively known as the epitranscriptome, has recently attracted renewed attention. mRNA methylation is required for normal Arabidopsis development and the first methylation maps reveal that thousands of Arabidopsis mRNAs are methylated. Arabidopsis is likely to be a model of wide utility in understanding the biological impacts of the epitranscriptome. We review recent progress and look ahead with questions awaiting answers to reveal an entire layer of gene regulation that has until recently been overlooked.

Modulation of stomatal development and movement is a promising approach for creating water-conserving plants. Here, we identified and characterized the PagHCF106 gene of poplar (Populus alba × Populus glandulosa). The PagHCF106 protein localized predominantly to the chloroplast, and the PagHCF106 gene exhibited tissue-specific expression pattern.

Suppressing Tymovirus replication in plants using a variant of ubiquitin.

RNA viruses have evolved numerous strategies to overcome host resistance and immunity, including the use of multifunctional proteases that not only cleave viral polyproteins during virus replication but also deubiquitinate cellular proteins to suppress ubiquitin (Ub)-mediated antiviral mechanisms. Here, we report an approach to attenuate the infection of Arabidopsis thaliana by Turnip Yellow Mosaic Virus (TYMV) by suppressing the polyprotein cleavage and deubiquitination activities of the TYMV protease (PRO). Performing selections using a library of phage-displayed Ub variants (UbVs) for binding to recombinant PRO yielded several UbVs that bound the viral protease with nanomolar affinities and blocked its function.

The Tapetum Determinant 1 (TPD1) family proteins are known to play a crucial role in the regulation of reproduction in plants, including Cenchrus americanus (pearl millet). However, members of TPD1 family proteins have not been fully identified. The current study aims to identify and characterize the TPD1 family proteins in Cenchrus americanus (L.

Oxidative stress is a major threat to plant growth and survival. To understand how plants cope with oxidative stress, we carried out a genetic screen for Arabidopsis (Arabidopsis thaliana) mutants with altered response to hydrogen peroxide (H2O2) in root growth. Herein, we report the characterization of one of the hypersensitive mutants obtained.

In the leucine (Leu) biosynthesis pathway, homeostasis is achieved through a feedback regulatory mechanism facilitated by the binding of the end-product Leu at the C-terminal regulatory domain of the first committed enzyme, isopropylmalate synthase (IPMS). In vitro studies have shown that removing the regulatory domain abolishes the feedback regulation on plant IPMS while retaining its catalytic activity. However, the physiological consequences and underlying molecular regulation on Leu flux upon removing the IPMS C-terminal domain remain to be explored in plants.
