AI Article Synopsis

  • A fragment of the prohibitin (Phb) gene was isolated and its expression in wild-type and mutant Arabidopsis thaliana seeds was analyzed, revealing high abundance of Phb mRNA in wild-type seeds.
  • The 3' untranslated region of the Phb gene exhibits notable features that may contribute to mRNA stability.
  • The study found that Phb in Arabidopsis does not interact with certain proteins (retinoblastoma-related protein or E2F) as seen in mammals, suggesting a different role in cell cycle regulation during seed germination.

Article Abstract

A fragment encoding a partial sequence of a prohibitin (Phb) gene was isolated. The expression of Phb mRNA and protein in seeds of wild type and mutant Arabidopsis thaliana is presented. Phb mRNA is abundant in wild-type seeds; thus, it may have sequence or structural characteristics responsible for this stability. The 3' untranslated region sequence of a Phb gene has interesting features. We found that Arabidopsis Phb does not interact with a retinoblastoma-related protein or E2F in a yeast two-hybrid system, thus suggesting that the plant protein may have not conserved such interaction, described for mammalian Phb. The possible role of Phb in cell cycle regulation during germination is discussed.

Gamete killers are genetic loci that distort segregation in the progeny of hybrids because the killer allele promotes the elimination of the gametes that carry the sensitive allele. They are widely distributed in eukaryotes and are important for understanding genome evolution and speciation. We had previously identified a pollen killer in hybrids between two distant natural accessions of Arabidopsis thaliana.

Functional conservation and divergence of arabidopsis VENOSA4 and human SAMHD1 in DNA repair.

Heliyon

January 2025

Instituto de Bioingeniería, Universidad Miguel Hernández, Campus de Elche, 03202, Elche, Spain.

The human deoxyribonucleoside triphosphatase (dNTPase) Sterile alpha motif and histidine-aspartate domain containing protein 1 (SAMHD1) has a dNTPase-independent role in repairing DNA double-strand breaks (DSBs) by homologous recombination (HR). Here, we show that VENOSA4 (VEN4), the probable ortholog of SAMHD1, also functions in DSB repair by HR. The loss-of-function mutants showed increased DNA ploidy and deregulated DNA repair genes, suggesting DNA damage accumulation.

Until recently, the lack of three-dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the role of the endoplasmic reticulum (ER). In this study, we perform three-dimensional reconstructions of serial FIB/SEM stacks and anaglyphs derived from volume rendering, cryo-scanning electron microscopy (cryo-SEM) and state-of-the-art electron microscopy immobilisation and imaging techniques.

Recent advancements in fluorescence-based biosensor technologies have enabled more precise and accurate Förster Resonance Energy Transfer (FRET) imaging within Agrobacterium-mediated plant transformation systems. However, the application of FRET imaging in plant tissues remains hindered by significant challenges, particularly the time-intensive process of generating transgenic lines and the complications arising from tissue autofluorescence. In contrast, protoplast-based FRET imaging offers a rapid and efficient platform for functional screening and analysis, making it an essential tool for plant research.

N-degrons are amino-terminal degradation signals. Non-acetylated first residues with bulky side chains were the first discovered N-degrons. In yeast, their ability to destabilize a protein depends on ubiquitin ligase Ubr1, which has a binding site for basic first residues, the UBR box, and one for hydrophobic first residues, the N domain.
