Cells are separated from their external environment by a membrane barrier, which ensures that certain ions, metabolic intermediates, and macromolecules, such as proteins, remain within the cell. However, life is not possible without exchange of material information with
Summary Cytoplasmic male sterility (CMS) in higher plants has been mainly studied cultivated species. In most cases, pollen abortion is linked to the presence of an additional mitochondrial polypeptide leading organelle dysfunction reproductive tissues. wild beet, both CMS and hermaphrodite coexist natural populations. The G cytoplasm widely distributed along Western European coast, previous genetic studies have demonstrated that this confers beet. present study, we identified two mutations...
The tagging-via-substrate approach designed for the capture of mammal prenylated proteins was adapted to Arabidopsis cell culture. In this way, are in vivo tagged with an azide-modified farnesyl moiety and captured thanks biotin alkyne Click-iT® chemistry further streptavidin-affinity chromatography. Mass spectrometry analyses identified four small GTPases ASG2 (ALTERED SEED GERMINATION 2), a protein previously associated seed germination gene network. is conserved plants displays unique...
In plants, the ABC transporter PDR (pleiotropic drug resistance) subfamily is composed of approximately 15 genes, few which have been analyzed. We identified NtPDR3, a Nicotiana tabacum gene belonging to cluster for no functional data was previously available. NtPDR3 found be induced in suspension cells treated with methyl jasmonate, salicylic acid, 1-naphthalene acetic or cembrene, macrocyclic diterpene. agreement identification putative iron deficiency element transcription promoter...
Abstract Rho of Plant (ROP) GTPases function as molecular switches that control signaling processes essential for growth, development, and defense. However, their role in specialized metabolism is poorly understood. Previously, we demonstrated inhibition protein geranylgeranyl transferase (PGGT-I) negatively impacts the biosynthesis monoterpene indole alkaloids (MIA) Madagascar periwinkle (Catharanthus roseus), indicating involvement prenylated proteins signaling. Here, show through...
Abstract Ducos et al. report that the farnesylated protein ASG2 is Arabidopsis ortholog of human WDCT1, which controls fat accumulation. Both proteins harbor.. (Altered Seed Germination 2) a prenylated in thaliana participates to abscisic acid signaling and proposed act as substrate adaptor for DDB1 (DNA damage-binding 1)-CUL4 (Cullin 4) E3 ubiquitin ligase complex. harbors WD40 TetratricoPeptide Repeat (TPR) domains, resembles well-conserved animal gene called ADP (antiobesity factor...
ATP binding cassette (ABC) proteins constitute one of the largest families transporters. In Arabidopsis thaliana, over 100 genes encoding ABC transporters have been identified. Here, we described expression pattern AtABCC13/MRP11, a member multidrug resistance associated protein MRP/ABCC subfamily, previously uncharacterized. The histochemical analysis transgenic harboring AtABCC13 promoter-β-glucuronidase gene fusion shows that was specifically with vascular bundles. Moreover, displayed...
Protein farnesylation is a post-translational modification regulated by the ERA1 (Enhanced Response to ABA 1) gene encoding β-subunit of protein farnesyltransferase in Arabidopsis. The era1 mutants have been described for over two decades and exhibit severe pleiotropic phenotypes, affecting vegetative flower development. We further investigated development quality seeds. While ovary contains numerous ovules, plant produces fewer seeds but larger heavier, with higher contents modified fatty...

Abstract Domain of unknown function 239 (DUF239) is a conserved sequence found in the catalytic site Neprosins which are specific secreted prolyl endopeptidases Nepenthes genus. participate nitrogen cycle by digesting preys trapped pitcher these carnivorous plants. Apart from that, DUF239s have been poorly documented We identified 50 genes containing DUF239‐coding sequences Arabidopsis genome that distributed across six distinct phylogenetic clusters. The chromosomal distribution suggests...
