Seedling temperature responses in Arabidopsis RRS-7

ABSTRACT: Plants have the capacity to sense and respond to even small changes in ambient temperature. Numerous thermomorphogenic responses can be observed in Seedlings including elongation of the hypocotyl, petioles and the primary root while leaf blade areas are reduced. Main objective of the experiment was the assessment of tissue-specific transcriptome responses in Arabidopsis seedlings exposed to elevated ambient temperatures, 5 days old Arabidopsis seedlings grown at 20°C in LD were shifted for 3 or 24h to 28°C. Control plants were kept at 20°C. At time of harvest, cotyledons and roots were dissected and collected separately from the hypocotyl. To minimize circadian effects, plant material was grown in several successive batches and harvested only for a period of 30 min per timepoint on several consecutive days. Shifts and harvest was performed at midday to late afternoon (see ZT in overall design).

Transcriptional reprogramming and stimulation of leaf respiration by elevated CO2 concentration is diminished, but not eliminated, under limiting nitrogen supply.

Project description:Transcriptional reprogramming and stimulation of leaf respiration by elevated CO2 concentration is diminished, but not eliminated, under limiting nitrogen supply. Arabidopsis plants were grown in either ambient (370 ppm) or elevated (750 ppm) CO2 with either ample N supply or limiting N supply. Leaf tissue was harvested from youngest most fully expanded leaves 35 days after plant germination at either midday or midnight.

Ethylene-independent Promotion of Photomorphogenesis by Cytokinin Requires a Functional Cytokinin and Light Signaling Pathway.

Project description:The transition of skotomorphogenesis to photomorphogenesis is induced by the perception of light and is characterized by the inhibition of hypocotyl elongation and opening of cotyledons. Although it is known that the plant hormone cytokinin, when applied in high concentrations, inhibits hypocotyl elongation in the dark-grown Arabidopsis plants, it is unclear to what extent this response is the result of cytokinin alone or cytokinin-induced ethylene production. We show that treatment of etiolated seedlings in presence of ethylene inhibitors (eg. AgNO3) or treatment of the ethylene-resistant mutant ein2, resulted in a significant inhibition of hypocotyl elongation. This indicates that cytokinin induced de-etiolation is largely independent of ethylene and suggests a close connection between the cytokinin two component system and the light singalling networks. We show that this cytokinin signal is mainly mediated through the cytokinin receptor ARIBIDOPSIS HISTIDIN KINASE 3 (AHK3) and the ARABIDOPSIS RESPONSE REGULATORS 1 (ARR1) in combination with ARR12. Interestingly, mutation of COP1, DET1 and CIN4/COP10 renders plants insensitive to cytokinin and these factors are indispensable for the transcriptional response during cytokinin induced de-etiolation which indicates that a functional light signaling pathway is essential for this cytokinin response. In addition, the cytokinin effect on hypocotyl elongation is highly dependent on the ambient light conditions where higher light intensities causes a switch in the response to CK from an inhibitor to a promoter of hypocotyl elongation.

Analyses of phyB-regulated genes by RNA-seq

Project description:The phytochrome family consists of five numbers (phyA-phyE) in Arabidopsis, of which phyB is the best characterized and shown to play a major role in mediating red light inhibition of hypocotyl elongation. In order to reveal the molecular basis for phyB-mediated red light signaling to promote photomorphogenesis, we analyzed the gene expression profile of red light-grown WT and phyB mutant seedlings by high throughput sequencing.

Growth temperature response in Arabidopsis

Project description:Moderate increases in the ambient temperature promote hypocotyl growth in Arabidopsis, and this response is totally dependent on the proper activity of the auxin, gibberellin, and brassinosteroid pathways. We have analyzed global the changes in gene expression that occur in Arabidopsis seedlings after a moderate increase in the growth temperature (20ÂºC to 29ÂºC for 2 hours). In order to understand how the different hormone pathways affect this growth response, the same transcription profiling analysis was conducted in seedlings deficient in each hormone. Keywords: Growth condition We performed three replicas of each sample category: wild type mock-treated, wild type PAC-treated, wild type NPA-treated, and det2-1 mutants. Samples transferred from 20ÂºC to 29ÂºC of replicas #2 and #3 were labelled with Cy3, whereas those kept at 20ÂºC were Cy5-labelled. Samples of replica #1 were reversed-labelled.
