In this study, the metabolic adjustments performed by maize (Zea mays L) seminal roots exposed to 10 or 100 mM NaCl or 16% (w/v) PEG at pre-emergence are compared, focusing on the proteomic changes after metal exposure.
In this study, the physiological phenotyping, RNA sequencing, widely targeted metabolomics, and phytohormone profiling were used to examine the responses of maize seedlings to progressive PEG-induced osmotic stress and their recovery after PEG removal.
RNA-directed DNA methylation (RdDM) in Arabidopsis thaliana depends on the synthesis of non-coding RNAs by nuclear RNA polymerase E (NRPE or Pol V) 1-3, but the mechanism by which Pol V is targeted is unknown. Here we show that genome-wide Pol V association with chromatin redundantly requires the ...
DNA methylation is a mechanism of epigenetic gene regulation and genome defense conserved in many eukaryotic organisms. In Arabidopsis, the DNA methyltransferase DRM2 controls RNA-directed DNA methylation in a pathway that also involves the plant specific RNA Polymerase V (Pol V). The Arabidopsis ge...
Time course of the transcriptome of desiccation-sensitive 2.7-2.9 mm-long radicles of Medicago truncatula seeds at different time points during incubation in a polyethylene glycol (PEG) solution at -1.7 MPa and 10°C, resulting in a gradual re-establishment of desiccation tolerance. Gene profiling wa...
Sour passion fruit (Passiflora edulis Sims) has economic and social relevance and is an alternative crop mainly for family farming agriculture. The use of micropropagation by somatic embryogenesis offers scale-up clonal propagation with high phytosanitary quality. The aim of this work was to evaluat...
