OTU5 tunes environmental responses by sustaining chromatin structure.

Phenotypic plasticity is dependent on the correct interpretation of environmental cues. We recently showed that the deubiquitinase OTU5 is required for orchestrating internal and external signals, tuning the morphogenesis of epidermal cells to the prevailing conditions. Homozygous otu5 mutants developed long and dense root hairs, resembling phosphate-deficient plants.

Differentially localized rice ethylene receptors OsERS1 and OsETR2 and their potential role during submergence.

Ethylene is gaseous plant hormone that controls a variety of physiologic activities. OsERS1 and OsETR2 are major ethylene receptors in rice that have been reported to have different regulatory functions. The GFP fused N-terminus of OsERS1 and OsETR2 showed differentially localization patterns when transiently expressed in onion epidermal cells.

Distinct role of Arabidopsis mitochondrial P-type pentatricopeptide repeat protein-modulating editing protein, PPME, in nad1 RNA editing.

The mitochondrion is an important power generator in most eukaryotic cells. To preserve its function, many essential nuclear-encoded factors play specific roles in mitochondrial RNA metabolic processes, including RNA editing. RNA editing consists of post-transcriptional deamination, which alters specific nucleotides in transcripts to mediate gene expression.
