Project description:This study provides a comparison of gene expression in two tomato cultivars, Moneymaker and M82, focusing on first internode and its innermost cell type pith—under two light conditions: white light with far-red supplementation (WL+FR) and the control condition of white light (WL). The samples were harvested at four time points leading to the point where internode elongation could be measured in response to WL+FR. The timepoints were 6, 24, 30, and 48 hours after treatment initiation.

Project description:To study the transcriptomic profile of wt and brc1 mutant axillary buds during the shade avoidance response, we simulated a canopy shade with a low R/FR light ratio. We treated plants with white light supplemented with far-red light (Red light = 29 μeinstein · m-2 seg-1, Far-Red light= 146 μeinstein · m-2 seg-1) for 8 hours. Control plants were left for 8 hours in white light (Red light = 29 μeinstein · m-2 seg-1, Far-Red light= 2.2 μeinstein · m-2 seg-1) . Six biological replicates of 7-8 plants were collected for each genotype and condition (wt WL, wt FR, brc1 WL, brc1 FR). Samples were compared wt WL vs wt FR and brc1 WL vs brc1 FR.

Project description:Arabidopsis is a shade avioding plant. Under simulated shade light with reduced red-to-far red (R:FR) ratio around 0.7, hypocotyls of Arabidopsis seedlings elongate, which is one of the typical shade avoidance responses.We discovered that when the R:FR ratio further decreases to around 0.1 (strong shade), the shade-induced elongation of hypocotyl is abolished and phytochrome A (phyA) mediates this response.In this study, we aim to examine the difference between shade and strong shade treatment and uncover the role of phyA in regulating the shade avoidance responses.

Project description:Plants grown under a canopy recognize changes in light quality and modify their growth patterns; this modification is known as shade avoidance syndrome. In leaves, leaf blade expansion is suppressed, whereas petiole elongation is promoted under the shade. However, the mechanisms that control these responses are largely unclear. Here, we demonstrated that both auxin and brassinosteroid (BR) are required for the normal leaf responses to shade. The microarray analysis of leaf blades and petioles treated with end-of-day far-red light (EODFR) revealed that almost half of the genes induced by the treatment in both parts were previously identified as auxin-responsive genes. Likewise, BR-responsive genes were overrepresented in the EODFR-induced genes. Hence, the auxin and BR responses were elevated by EODFR treatment in both leaf blades and petioles, although opposing growth responses were observed in these two parts. The analysis of the auxin-deficient doc1/big mutant and BR-deficient rot3/cyp90c1 mutant further indicates that auxin and BR were equally required for the normal petiole elongation response to the shade stimulus. In addition, the spotlight irradiation experiment revealed that phytochrome in leaf blades but not that in petioles regulated petiole elongation, which was probably mediated through regulation of the auxin/BR responses in petioles. On the basis of these findings, we conclude that auxin and BR cooperatively promote petiole elongation in response to the shade stimulus under the control of phytochrome in the leaf blade. The WT seedlings were grown for 19 days under continuous white light condition before experimental treatment with three light conditions. Seedlings were either maintained in white light for 2 h (WL), incubated in the dark condition for 2 h (D), or experienced a pulse irradiation of FR light before incubated in the dark condition for 2 h (FRD). Total RNAs were separately prepared from leaf blades and petioles after each light treatment. Three independent biological replicates were used.

Project description:Plants respond to changes in the red:far red ratio (R:FR) of incident light. A reduction in this ratio (increase in FR) results in the Shade Avoidance Response (SAR) with associated changes in gene expression. The Phyotchrome-Interacting Factors (PIFs) are bHLH transcription factors known to be involved in the SAR. An analysis of changes in gene expression in WT and quadruple pif1pif3pif4pif5 (pifq; Leivar et al., 2008 (PMID 19920208)) mutant seedlings in response to an increase in FR should identify primary targets of PIF signaling. We used microarrays to examine the SAR in WT (Columbia) and pifq mutant Arabidopsis seedlings. Arabidopsis WT and pifq mutant seeds were plated on GM medium without sucrose at room temperature. During this procedure, the seeds were routinely exposed to white light (WL) for a total of 1.5 hours after imbibition. Seeds were then stratified for 5 days at 4ºC in darkness, and then grown in WL (19 umol/m2/s, R/FR ratio of 6.48) for 2 days at 21°C (WL0 samples). Two-day-old WL-grown seedlings were then maintained in the same fluence rate of WL supplemented with far-red light (WL-FR, R/FR ratio of 0.006) for 1 (FR1), 3 (FR3) or 24 (FR24) hours before harvesting. Control seedlings were also maintained in parallel in the same fluence rate of WL for 24h (WL24) before harvesting. Three different biological replicates of each treatment were grown separately and extracted, processed, and analyzed independently.

Project description:Aim of the experiment is the identification of genes differentially regulated in phyA seedlings relative to wild type after prolonged exposure to low R/FR. To this end, gene expression changes were analysed in Arabidopsis wild-type and phyA knock-out mutant seedlings exposed to low R/FR light. The experiment was designed to enable comparison between the different genotypes exposed or not exposed to low R/FR light.

Project description:Orchid Dendrobium Sonia (Sonia) has wide demand in floral market throughout the world due to its vibrant coloured flowers, flowering recurrence and dense inflorescence. Effects of different monochromatic light qualities (red, far-red, blue, white) on different developmental and growth responses such as seed gemination, shoot and root growth, chlorophyll and carotenoid accumulation were studied in Sonia. Asymbiotic seed germination was the highest under blue or white light (80%, p<0.001) and least under far-red (55%, p<0.001) suggesting that it could either be controlled by an exceptional novel function of Cryptochrome 1 or the blue wavelengths perceived by PHYA or PHYB in Sonia. All analyses were done in 6-months-old plants till 1 year of age. Shoot length increased significantly in white or red light (3.7-fold, 3.5-fold respectively) while was least under far-red (decreased by 1.6-fold) indicating the major regulatory role of PHYB for shoot growth. Root growth in red in Sonia was more similar to hypocotyl adventitious root (HAR) formation genetically considering PHYB transcript expression. We suggest that the root growth (HAR) under red in Sonia is partly attributed to PHYB, negatively regulated with HY5 transcription factor and positively associated with auxin biosynthesis and accumulation gene BABY BOOM (BBM2) and efflux carriers such as LIKE AUXIN RESISTANT 2 and 3 (LAX2, LAX3). Highest chlorophyll content under far-red and blue might be a hyper-response of SAR under FR light in Sonia. Taxonomic tree analysis finds Sonia closer to Phalenopsis and Dendrobium catenatum Lindl. The three phytochromes and one cryptochrome sequences which were similar to PHYA, B, C and CRY1 respectively. CRY1 was retrieved with one more isoform CRY1_X2, with all these sequences more similar to those of Oryza.sativa. Further study can clarify the indicating reason of a probable gene loss which is evident from the absence of any sequence similar to CRY2 in root RNA isolates of Dendrobium Sonia.

Project description:This RNA-seq was designed to help gain understanding on the genetic program behind phytochrome developmental time dependent control of leaf 3 (L3) cell proliferation and expansion phases, to ultimately regulate organ growth. Briefly, Arabidopsis thaliana Col-0 plants were grown under a light : dark (LD) 12 h : 12 h photoperiod, at a 100 µmoles/m2/s fluence rate and 21 °C of constant temperature. Plants were then exposed to either daily End of Day (EoD) far-red (FR, 40µmoles/m2/s of FR light (730nm) for 10 minutes) from day 6 and harvested L3 primordia or blade tissue at days 13, 16 and 20, or EoD FR from day 18, sampling at day 20. Plant kept under white light (WL) conditions were used as controls.

Project description:This application is the second part of a BBSRC-funded grant to compare and contrast the plastid-signalling pathways disrupted by Norflurazon and far-red light treatment of Arabidopsis seedlings. The first application of this laboratory to GARNet's Affymetrix service (2002-08-25-17.41.49_McCormac) addressed the Norflurazon pathway; this application addresses the far-red pathway. The assembly of photosynthetic complexes in developing chloroplasts is critical to the establishment of the autotrophic plant. This requires light-mediated upregulation of both nuclear- and chloroplast-encoded genes. The expression of such photosynthetically-associated nuclear genes is also often dependant on a retrograde plastid signal which emanates from chloroplasts to modulate nuclear transcription. Extensive studies using the herbicide Norflurazon to knock-out the plastid signal (including this lab's previous Affymetrix application to GARNet) are identifying the affected gene sets. However, genetic studies have indicated the existence of more than one plastid signalling pathway. We have recently investigated a phytochrome A-mediated, far-red (FR) input pathway which blocks subsequent chloroplast development under white light (WL). This has also been found to inhibit the transcription of a small group of known nuclear-encoded plastidic proteins. Here we wish to establish how wide-reaching this FR-effect is on nuclear transcription, and will directly compare the affected gene groups with those identified from our earlier (and other's) studies with a Norflurazon treatment. In this array experiment we will compare RNA from seedlings grown in complete darkness (D) before transfer to WL, with that of seedlings preconditioned under a restricted wavelength FR source before exposure to WL. This comparison of FR- and Norflurazon-affected gene groupings will indicate whether the plastid signalling pathways are likely to be the same, overlapping or highly divergent. As well as wild-type seedlings, the gun1,gun5 mutant line is to be used as both these alleles are well established as alleviating the Norflurazon-inhibited pathway, but their affect on the FR-pathway is less clear. A single replicate of a phyA-null mutant line will also be included in order to differentiate between specific phytochromeA-mediated responses and other FR effects. It is envisaged that, in general, D- and FR-treated samples of the phyA mutant line will respond in the same way as each other and as the wild-type D-treated samples and, thus, the lack of a biological repeat in this case is not a major short-fall. The proposed experiment will consist of: wild-type: D-pretreated (x2 biological replicates) wild-type: FR-preconditioned (x2) gun1,gun5: D-pretreated (x2) gun1,gun5: FR-preconditioned (x2) phyA: D-pretreated (x1) phyA: FR-preconditioned (x1) Keywords: strain_or_line_design
