Open AccessExogenous miRNAs induce post-transcriptional gene silencing in plants
Plants seem to take up exogenous RNA that was artificially designed to target specific genes, followed by activation of the RNA interference (RNAi) machinery. It is, however, not known whether plants use RNAs ...

Open AccessArabidopsis phenoty** reveals the importance of alcohol dehydrogenase and pyruvate decarboxylase for aerobic plant growth
Alcohol dehydrogenase (ADH) and pyruvate decarboxylase (PDC) are key to the establishment of the fermentative metabolism in plants during oxygen shortage. Most of the evidence that both ADH and PDC are require...

Universal stress protein HRU1 mediates ROS homeostasis under anoxia
Plant survival is greatly impaired when oxygen levels are limiting, such as during flooding or when anatomical constraints limit oxygen diffusion. Oxygen sensing in Arabidopsis thaliana is mediated by Ethylene Re...

Transcript profiling of chitosan-treated Arabidopsis seedlings
In nature, plants can recognize potential pathogens, thus activating intricate networks of defense signals and reactions. Inducible defense is often mediated by the detection of microbe or pathogen associated ...

Effect of sugars on auxin-mediated LeEXPA2 gene expression
The paper deals with the effect of sugars on LeEXPA2 expression in tomato (Lycopersicon esculentum) hypocotyl segments, which is a well-studied system for analysis of cell elongation. We tested the interactions b...

DjPiwi-1, a member of the PAZ-Piwi gene family, defines a subpopulation of planarian stem cells
Planarian regeneration, based upon totipotent stem cells, the neoblasts, provides a unique opportunity to study in vivo the molecular program that defines a stem cell. In this study, we report the identificati...

Identification of sugar-modulated genes and evidence for in vivo sugar sensing in Arabidopsis
Sugar status regulates mechanisms controlling growth and development of plants. We studied the effects of sucrose at a genome-wide level in dark-grown 4-day-old Arabidopsis thaliana seedlings, identifying 797 gen...

Glucose repression of α-amylase in barley embryos is independent of GAMYB transcription
The induction of α-amylase triggered by gibberellic acid in barley embryos is repressed by sugars. We investigated the effects of glucose on the gibberellin signal transduction pathway to localize the site of ...

Glucose modulates the abscisic acid-inducible Rab16A gene in cereal embryos
Glucose effects on the expression of the abscisic acid-inducible Rab16A gene were examined in rice and barley embryos. Glucose feeding to rice embryos negatively affects the endogenous abscisic acid content and r...
