Project description:Sugarcane one-eyed seed sets obtained from a variety sensitive to drought conditions (cv. SP90-1638, CTC, Brazil) were cultivated on moist sand for 15 days. The plants were transferred to pots containing moist sand and were irrigated with Hoagland’s solution (Hoagland and Arnon, 1950). Regular watering was maintained for 90 days and suppressed after this period for the experimental group. Leaves were collected 24 h, 72 h and 120 h after exposure to drought conditions for the control and experimental groups. Samples were collected and immediately frozen in liquid nitrogen. Leaves from six plantlets were used for each time point. Extraction of total RNA was performed separately on each sample pool. Keywords: time course of stress response

Keywords: time course of stress response RNA from experimental sample and from its respective control sample (untreated plants) was used for hybridization to dual channel arrays. Two biological replicates were used for each experimental point. The quantification of each hybridization was submitted in two files, one for each slide side (technical replicates).

Project description:Cuttings from Razegui cultivar were cultivated in sand for 2 months according to the method we have described previously (Azri et al. 2020). Then grapevine plantlets were further grown in pots containing sand/peat mixture (2/1, v/v), in a controlled greenhouse (16 h light/8 h dark at PAR 300 μmol m-2 s-1 photoperiod, 24 °C day/20 °C night temperature and 65-75% relative humidity). They were watered daily with tap water and supplemented once a week with 100 mL of Gibeaut’s nutrient solution (Gibeaut et al. 1997). Drought stress was applied according to our previously described procedure (Azri et al. 2020): plants with 10-15 leaves were either irrigated daily with water (control) or non-irrigated at all (water deficit). After 4 time points (day 0, 4, 8 and 16) of water deficit, the 4th fully-developed leaf was harvested and used for physiological analyses. Three independent biological experiments were performed consisting each in 2 treatments (control and water deficit) and 3 plants per time point and treatment. Proteomic analysis was performed on the 5th fully developed leaves at the time point 16 days of drought treatment. Irrigated and non-irrigated leaves were harvested immediately in liquid nitrogen and stored at - 80 °C until analysis. Three biological replicates were carried out for each treatment.

Project description: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.

Project description:To find out the genotype specific differentially expressed genes in response to N source Two contrasting Indica rice genotypes namely, Nidhi and Panvel 1 were used. Arnon Hoagland medium with either nitrate or urea were used as fertilizer sources. Two N doses, normal (15 mM of N) was used as control while low (1.5mM of N) was used as test.

Project description:The response to moderate and heavy drought of two Solanum tuberosum ssp. Andigena varieties, Sullu (NP 03.03) and SA 2563 (NP 03.01), planted in rain- and soil water protected fields in the Peruvian highlands are compared. Previous experiments indicate that Sullu has a greater capacity for yield maintenance under drought than SA 2563. Both clones have similar morphological properties, vegetative periods and rooting depths, so it can be assumed that the cause for increased drought tolerance of clone NP 03.03 is rather due to physiological or biochemical mechanisms, than to drought escape by deep rooting or earliness. Sullu and SA 2563 were planted in a random block design with 5 plants per bloc and 7 repetitions per treatment. Treatments: (1) drought stress, (2) irrigated control The plants were drip-irrigated in both treatments until tuberization (until day 84 after planting). Subsequently, the irrigation was stopped in the drought field, but continued in the control field. The soil moisture content in the control field was kept near field capacity. Planting date: October 05 2004 Start of drought treatment (during tuberization, 84 days after planting): December 28 2004 First sampling (soil water potential: -0.3 mPa 114 days after planting): January 27 2005 Second sampling (soil water potential –0.6 MPa, 134 days after planting): February 15 2005 Harvest: March 19 2005 (165 days after planting) The experimental design includes gene expression analysis in leaves, roots and stolons at two time points, when soil water potential reaches -0.3 and –0.6 MPa. Gene expression changes will be set in relation with physiological and agronomical data obtained in the same experiment. Keywords: Direct comparison

Project description:Rice (Oryza sativa), the major staple food crop is being cultivated under varying ecosystems ranging from irrigated lowland to rainfed upland environments. Improvement in the rice production under drought prone unfavourable environment depends on the development of drought tolerant genotypes which needs thorough understanding of physiological and molecular events behind the tolerance mechanism. There is considerable genetic variation for drought tolerance mechanism within the cultivated gene pool. To understand the diversity of drought response, two indica rice genotypes namely, i) Apo, an up-land drought tolerant indica veriety from Philippines and ii) IR64, a popular high yielding drought susceptible genotype were selected for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under control and drought stressed conditions during vegetative phase.

Project description:Barley1 GeneChip was used to investigate transcriptome changes associated with boron (B) toxicity in a sensitive barley cultivar (Hordeum vulgare L. cv. Hamidiye). Eight day old aseptically grown seedlings were subjected to 5 or 10 mM boric acid (B(OH)3) treatments for 5 days and expression profiles were determined with DNA microarrays using total RNA from leaf tissues. Surface sterilized seeds were aseptically germinated and grown on half strength Hoagland’s solution (Hoagland and Arnon, 1950) (pH 5.8) solidified with Phytagel® for 8 days at 23±2ºC with 16 h light (400 µmol m–2 s–1) and 8 h dark photo-cycle with 70% relative humidity. Seedlings were transferred to sterile hydroponic cultures for B treatment, which was applied immediately after transfer as half strength Hoagland’s solution containing either 5 mM B(OH)3 (5B) or 10 mM B(OH)3 (10B) for another 5 days under the same physical conditions. Control (C) groups were transferred to half strength Hoagland’s solution without extra B(OH)3. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Mehmet Tufan OZ.
