Sugarcane transcriptome - Phosphate starvation

ABSTRACT: Rooted sugarcane plantlets, originated from in vitro meristem culture (genotype SP80-3280, CTC, Brazil), were greenhouse acclimatized by initial cultivation on 1/20th strength Hoagland and Arnon (1950) nutrient solution. Nutrient solutions were aired from an oil-less compressor and replaced every 7 days, increasing nutrient concentration to ¼ strength in 3 weeks. Plants were then individually transferred to 2.8 L pots filled with fresh ¼ strength nutrient solution. After one week, half of the plants were transferred to fresh solution containing 250 µM Pi, while the other half was transferred to nutrient solution deprived of phosphate (Pi), with H2PO4 being replaced by H2SO4 (Muchhal et al., 1996). Roots from six plants from each treatment (0 and 250 µM Pi) were harvested 6, 12, 24 and 48 h after exposure to phosphate starvation and immediately frozen in liquid nitrogen. For each time point and each treatment, root samples were aggregated in three pools of two samples each. Extraction of total RNA was performed separately on each sample pool.

Proteome analyses of low phosphorus responses in Stylosanthes guianensis leaves

Project description:The seeds of stylo (Stylosanthesis guianensis) genotype T277 were germination for 3 days and then precultured in half-strength Hoagland solution containing 250 μM KH2PO4 for 10 days. Subsequently, Stylo seedlings were treated with 250 μM KH2PO4 (High-Pi) or 5 μM KH2PO4 (Low-Pi) in fresh half-strength Hoagland solution. The leaf samples were harvested after 18 days of treatments for the label-free proteomic analysis. There were three biological replicates in each treatment.

Identification of differentially regulated genes in Populus deltoides subjected to copper stress using 4.6K cDNA arrays

Project description:cDNA macroarray expression profiling was carried out in poplar roots in order to identify genes regulated in response to exposition to copper stress. For this purpose, plants of a Populus deltoides clone grown in a hydroponic system during four weeks were incubated in a nutrient solution (Hoagland's modiefied salt, ¼ strength) supplemented with copper (0 µM (control), 30 µM and 60 µM). Roots were sampled at 12 and 24 h after exposition in a time-course experiment.

Low P stress transcriptome of control rice variety (Dongjin-byeo) and NtPT1-trasngenic rice (PT 1-7-8)

Project description:To understand expression of candidate gene located on QTLs for phosphate sensitivity traits under low P using NtPT1-transgenic rice with increased Pi uptake efficiency and gene expression profile at the V3-stage seedling through the 60K Rice Whole Genome Microarray Uniformly germinated seedlings were transferred to a hydroponic system filled with aerated standard solution (normal P, 320 M Pi) and grown for 2 weeks in a glasshouse at 25°C/18°C (day/night) under a natural photoperiod (about 16 h). The composition and concentration of each element in the standard solution were as follows: N (1.43 mM), P (0.32 mM), K (0.51 mM), Ca (0.75 mM), Mg (1.64 mM), Fe (59.37 μM), B (18.92 μM), Mn (9.50 μM), Mo (0.10 μM), Zn (0.15 μM), Cu (0.16 μM), and citric acid (70.72 μM) (Yoshida et al., 1976). Some of the two-week-old seedlings were transferred to the low P solution (the same nutrient solution containing 32 M Pi) over a period of 5 days to expose them to P-deficiency condition. Control plants were maintained in the standard solution for the entire period.

Transcription profiling of Arabidopsis roots from plants grown in nutrient solutions with various concentrations of nitrate and sucrose

Project description:We used Arabidopsis thaliana Col-0 for all experiments. The plants were grown hydroponically on nutrient solution as described previously [Plant J 1999, 18(5):509-519]. Briefly, plants were grown on sand, placed in custom-designed styrofoam rafts, in a growth chamber (EGC, Chagrin Falls, OH, USA) at 22°C with 60 mmol photons m-2s-1 light intensity and 8 h/16 h light/dark cycles. The seeds were initially germinated in tap water. After one week, the water was replaced with a complete nutrient solution [Plant J 1999, 18(5):509-519]. All the experiments were performed with 6 week old plants. Nutrient solutions were renewed weekly and on the day before the experiments. For treatments, individual rafts were transferred to containers with 300mL of nutrient solution supplemented with various concentrations of nitrate (as a mix of 2/1 KNO3/Ca(NO3)2) and/or sucrose. The N-free nutrient solutions contained 0.25 mM K2SO4 and 0.25 mM CaCl2 instead of KNO3 and Ca(NO3)2. Plants were transferred to treatments media at the beginning of the light period and were harvested 8h afterwards. Roots and leaves were harvested separately and quickly frozen in liquid N2.

Differential gene expression patterns in potassium-starved and Caesium-treated plants

Project description:At high concentrations ceasium (Cs) is toxic to plant growth. This toxic effect may occur when Cs blocks potassium (K) uptake mechanisms in plants. Consequently, plants starved of K and plants exposed to toxic concentrations of Cs should have similar gene expression patterns. To test this hypothesis, Arabidopsis will initially be grown on agar containing 1/10 MS salts before being transferred to either 1/10 MS nutrient solution (control plants), 1/10 MS nutrient solution containing 2 mM Cs, or 1/10 MS nutrient solution with no K. Roots and shoot will then be harvested seven days after transfer and used to challenge ATH1 GeneChips.

Transcriptome profiling in two maize inbreds differing in cold-sensitivity.

Project description:We investigated effect of severe cold on transcriptome changes in two inbred maize lines, chilling-sensitive ETH-DL3 and chilling-tolerant ETH-DH7. Kernels were germinated in wet sand in darkness at 25C. Seedlings were transferred to growth chamber (day/night temperature 24/22C, photoperiod 14/10 h, light 250 umol quanta x m-2 x s-1) and grow in pots containing Knop's nutrient solution supplemented with Hoagland's micro-nutrients. After full development of the 3rd leaf (fully developed ligular region) plants were used in experiment. The experiment was begun at the start of the dark period. Half of the plants were transferred to cold chamber (day/night temperature 8/6C, photoperiod 14/10 h, light 250 umol quanta x m-2 x s-1) other half served as control (day/night temperature 24/22C, other parameters was the same as for cold treatment). After dark period (10h) and 200 minutes of light period samples were taken. Each sample consisted of the middle part of the 3rd leaf blade, pooled from three plants and frozen in liquid nitrogen. The experiment was replicated four times with two replications dye swapped.
