Transcription profiling of Arabidopsis thaliana phytochrome interacting factors 4 and 5 redundantly limit seedling de-etiolation in continuous far-red light.

Project description:Phytochromes are red/far red photosensors regulating numerous developmental programs in plants. Among them phytochrome A (phyA) is essential to enable seedling de-etiolation in continuous far-red (FR) light a condition mimicking the environment under a dense canopy. The ecological relevance of this response is demonstrated by the high mortality rate of phyA mutants germinating in deep vegetational shade. phyA signaling involves a direct interaction of the photoreceptor with members of the bHLH transcription factor family, PIF1 and PIF3 (Phytochrome Interacting Factor). Here we investigated the involvement of PIF4 and PIF5 in phyA signaling and found that they redundantly control de-etiolation in FR light. The pif4pif5 double mutant is hypersensitive to low fluence rates of FR light. This phenotype is dependent on FR light perception by phyA but does not rely on alterations of the phyA level. Our microarrays analysis shows that PIF4 and PIF5 are part of an inhibitory mechanism repressing the expression of some light-responsive genes in the dark and are also needed for full expression of several growth-related genes in the light. Unlike PIF1 and PIF3, PIF4 and PIF5 are not degraded in response to FR light indicating that they are light-regulated by a different mechanism. Our genetic analysis suggests that this is achieved through the sequestration of these PIFs by the closely related bHLH transcription factor HFR1 (long Hypocotyl in FR light). Experiment Overall Design: he pif4pif5 double mutant were compared to wild-type plants when kept in the dark or subjected to 1 or 24 hours of 0.5 or 5 Âµmol/m2/s far-red light respectively.

Identification of rice ethylene-response mutants and characterization of mhz2 and mhz8 in distinct ethylene response and yield trait regulation

Project description:Ethylene plays major roles in adaptive growth of rice plants in water-saturated soil; however, ethylene signaling in rice is largely unclear. Here, we report identification and characterization of ethylene-response mutants based on distinct ethylene-response phenotypes of dark-grown rice seedlings. The seeds were soaked in tap-water and germinated at 37Â°C in the dark for two days (change the water daily). For ethylene treatment, we reduced the amount of water to 1.5-1.7cm below the seeds.Three-day old seedlings were treated with ethylene (10 ppm) for 8 hours at 28Â°C in the dark. Seedling grown in the air was used as control. We isolated RNA from roots and shoots of wild-type and mutant.

Transcription profiling of Arabidopsis phyA and phyB mutants, and wild type plants, grown in the dark

Project description:Phytochromes mediate a profound developmental shift when dark-grown seedlings are exposed to light. Here we show that a subset of genes is up regulated in phytochrome B (phyB) mutants even before dark-grown seedlings are exposed to light. Most of these genes bear the RY cis motif, which is a binding site of the transcription factor ABSCISIC ACID INSENSITIVE 3 (ABI3), and the phyB mutation also enhanced ABI3 expression. These changes in transcriptome have physiological consequences as seedlings of the abi3 mutant showed enhanced responses to pulses of far-red light, while ABI3 overexpressers exhibited the opposite pattern. Seedlings of the wild type derived from seeds germinated in full darkness showed enhanced expression of genes bearing the RY cis motif and reduced responses to far-red light. We propose that, via changes in ABI3 expression, light, perceived mainly by phyB in the seed, generates a downstream trans-developmental phase signal that pre-conditions the seedling to its most likely environment. , ,
