Project description:rs08-02_nad. Dark and light. Establish which transcripts are affected by changes in NAD concentration, and whether this depends on light/dark. Three genotypes: Two lines of Arabidopsis transformed to overexpress QPRT, an enzyme involved in NAD synthesis (NadC4.11 and NadC15.3) and a third control line transformed with an empty vector (162). Leaf discs from the two lines of the QPRT+ plants were incubated with quinolinate, the QPRT substrate, to boost leaf NAD. Discs from the empty vector control were incubated on a buffer withour quinolinate. The experiment was performed in the light and the dark. The aim is to compare the QPRT+ quinolinate samples with the empty vector samples, both for the sample series generated in the light and that generated in the dark. Keywords: treated vs untreated comparison

Project description:TMV-resistant (N), -susceptible (n), and enhanced susceptible mutant sun1-1 (N) tomato were grown in asceptic conditions in growth chambers (25º, 16hr/8hr light dark). 4-5 week old tomato were treated with TMV leaf sap or mock leaf sap, and leaf tissue was collected after 3, 9, and 27 hours. RNA was isolated from each sample (leaf tissue from one plant/one treatment/one timepoint), using standard TIGR protocols, and 25ug of total RNA was labeled using TIGR indirect labeling protocols. The experiment was repeated three times. Keywords: Direct comparison

Project description:When Arabidopsis seedlings are grown in the dark, their shoot meristem remains in a repressed state and does not develop leaves. The tight control of leaf development by light provides the opportunity to analyse a fundamental plant developmental process in its very early stages. We have observed that activation of photoreceptors in dark-grown seedlings leads to a rapid and dramatic increase in mitotic activity in and around the shoot meristem. Cotyledons also exhibit an induction of cell cycle activity by light, but this consists of endoreduplication and occurs later. Many other processes take place upon induction by light, including the development of the photosynthetic apparatus and the synthesis of sunscreens, but these processes are expected to take place in both the leaf primordia and the cotyledons. We have used this information to carry out a whole transcriptome analysis of shoot meristem activation and early stages of leaf development by light. For this we dissected the shoot apical regions from seedlings grown in the dark or 1, 2, 6, 24, 48 or 72 h after transfer to light. We also dissected cotyledons from equivalent seedlings grown in the dark or 1 or 6 h after transfer to light. From these samples we obtained RNA used for hybridisations against the ATH1 GenChip.

Project description:We performed expression profiling experiments on two-week old rice leaf tissues grown in light and dark condition with the rice 47k array. Four biological replicates and a dye-swap were used. To generate more consistent results on light vs dark response in rice, biological replicates were prepared from 4 different varieties such as Kitaake, Nipponbare, Tapei309 and IR24 because individual genetic background can affect to expression profile (Townsend et al., 2003). Gene expression was assayed by probing the microarray with pooled Cy3 and Cy5 labeled cDNAs derived from 0.5-1.0ug high quality mRNA prepared from leaf samples. Keywords: Direct comparison

Project description:We investigated chilling response of seedlings of three inbred maize lines: chilling tolerant S68911, chilling-sensitive S160 and moderate chilling-sensitive S50676. Kernels were germinated in wet sand in darkness at 25C. Seedlings were transferred to growth chamber (photoperiod 14/10h, temperature 24, light 250 umol quanta x m-2 x s-1), grown till the third-leaf stage and used in experiment. Chilling treatment started at the start of the dark period and lasted 38h (10h dark, 14h light,10h dark, 4h light). Growth conditions was as previously described but temperature was set to 14 (light/dark). At the same time control plants were grown as previously described. There were three biological replications of hybridization scheme.

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:To find the miRNAs that may be involved in dark-induced leaf senescence, we identified miRNAs by microarray platform using Arabidopsis thaliana leaves from both whole darkened plants (DPs) and individually darkened leaves (IDLs). Control, IDLs and DPs were treated for 2, 4 or 6 d in the same climate chambers (16 h light/8 h dark, 250 mmol m-2 s-1).

Project description:Basal leaf removal has been widely practiced to increase cluster sunlight exposure, control berry rot and eventually improve grape berry quality. Early leaf removal performed in cool region appeared to benefit the accumulation of norisoprenoids and monoterpenes. However, effects of this canopy management and leaf moving on volatile profiles and transcriptome of grape berry in warm region characterized with strong sunshine and arid climate were paid less attention. To cope with multiple possible effects caused by global warming, researches in warm region are urgently needed to provide a guide for adjusting the sunlight exposure treatment to adapt the climate change.In Manas county of Xinjiang province, sunlight exposure treatments performed in this study resulted in decreased β-carotene and lutein, which mainly responsible for the reduced norisoprenoids in ripening grapes. Substrate competition due to the up-regulation of VvTPS-a and VvNCED3 may contribute to the decreased concentration of monoterpenes in exposed berries. The notable increased C6 alcohols in the grape berries treated by leaf removal applied at veraison (LR-V), was mainly attribute to the enhanced substrate availability of linoleic acid and linolenic acid together with the higher expression of VvLOXO and VvADH1. Free C6 aldehyde was reduced by half leaf removal applied at veraison (HLR-V), leaf moving at veraison (LM-V) and leaf removal applied at berry pepper-corn size (LR-PS). Moreover, transcriptomic analysis indicated that both LR-V and LM-V treated grape berry implemented multiple stress-mitigation strategies to acclimate the improved sunlight exposure. Interestingly, photosynthesis-related genes in grape berry were primarily up-regulated by LR-V as a consequence of carbohydrate source removal rather than improved sunlight exposure. Weighted gene co-expression network analysis (WGCNA) suggested that the genes encoding malate synthase and 3-oxoacyl-(acyl carrier protein) reductase show a significant correlation with the accumulation of C6 alcohol.
