Project description:The purpose of this study is to analyze maize shoots growth under negative pressure to stabilize soil water content，Maize plants were subjected to two irrigation treatments. The first treatment was soil moisture dry-wet cycles, which was obtained using drip irrigation (control, DW). The second treatment was negative pressure to stabilize soil water content treatment (SW), which was obtained using the negative pressure irrigation (NPI) system.

Project description:Transcriptome analysis was performed on the rhizome tissues of Atractylodes macrocephala under different treatments. The four treatments were: sterile water irrigation alone, FS root irrigation, FS and AM201 root irrigation, and FS combined with methyltobuzin (TM) root irrigation. And the differential genes between AM201 and FO groups were identified and compared, which helps to reveal the resistance mechanism of AM201 to Atractylodes macrocephala root rot disease

Project description:Drought is one of the most serious abiotic stresses, under which the crop yield is significantly reduced. Elite winter wheat cultivar Henong 341 (Triticum aestivum L.) was grown in experimental fields of China Hebei province (116°37′23″E, 37°41′02″N) Two different treatment conditions were designed: rain-fed (no water irrigation) and well-watered (water irrigation) conditions at jointing and flowering stages. Each treatment included three biological replicates and each plot was 25m2. In this study, a comprehensive phosphoproteomic analysis of developing grains of 26th day after flowering (DAF) in Chinese bread wheat cultivar Henong 341 under well-watered and water-deficit conditions was performed by means of TiO2 enrichment, LC/MS/MS analysis, and Label-free peptide-intensity quantification. Under well-watered conditions, a total of 590 unique phosphopeptides corresponding to 603 nonredundant phosphorylation sites, representing 471 phosphoproteins, were identified. While under water deficit, 63 unique phosphopeptides, corresponding to 61 phosphoproteins, were found to be differently regulated in phosphorylation status compared to well-watered conditions (≥2 fold intensities).

Project description:A cultivation facility that can assist users in controlling the soil water condition is needed for accurately phenotyping plants under drought stress in an artificial environment. Here we report the Internet of Things (IoT)-based pot system controlling optional treatment of soil water condition (iPOTs), an automatic irrigation system that mimics the drought condition in a growth chamber. The Wi-Fi-enabled iPOTs system allows water supply from the bottom of the pot, based on the soil water level set by the user, and automatically controls the soil water level at a desired depth. The iPOTs also allows users to monitor environmental parameters, such as soil temperature, air temperature, humidity, and light intensity, in each pot. To verify whether the iPOTs mimics the drought condition, we conducted a drought stress test on rice varieties and near-isogenic lines, with diverse root system architecture, using the iPOTs system installed in a growth chamber. Similar to the results of a previous drought stress field trial, the growth of shallow-rooted rice accessions was severely affected by drought stress compared with that of deep-rooted accessions. The microclimate data obtained using the iPOTs system increased the accuracy of plant growth evaluation. Transcriptome analysis revealed that pot positions in the growth chamber had little impact on plant growth. Together, these results suggest that the iPOTs system represents a reliable platform for phenotyping plants under drought stress.

Project description:Six months old seed grown under well-watered greenhouse conditions were used in the current study. The seedlings of the two wild emmer wheat genotypes were vernalized on a moist germination paper (Hofman Manufacturing, Inc, Jefferson, OR, USA) for three weeks in the dark at 4oC, followed by three days acclimation at 24oC. Seedlings were then transplanted into 5L pots containing a mixture of pure quartz sand and peat (4:1 v/v), supplemented with a slow release fertilizer (2 g/L, Osmocote® Standard 14-14-14, Scotts-Sierra Horticulture, Marysville, OH, USA) and by a weekly application of 100 ml/pot of 0.5X Murashigi and Skoog growth solution (Sigma Chemical Co., St Louis, MO, USA). Pots were placed in a screen-house under natural winter conditions (December to February; 5-18°C) in Haifa, Israel (Mt. Carmel; 35o01′ E, 32o45′ N; 480 m above sea level) for 10 weeks and irrigated daily by a drip irrigation system. Three weeks prior to application of terminal drought stress, the pots were transferred to a controlled environment greenhouse (22/18 oC; 12 h day/12 h night) in order to prevent rainfall during the drought experiment. Five pots per genotype served as biological replicates, plants of three pots of each genotype/treatment were used for transcriptome study whereas two additional pots were used for quantitative PCR analysis (altogether five biological replicated of were used for quantitative real time PCR). Three individual plants were grown in each pot, one plant was used for measurements of leaf relative water content (RWC) (Barrs and Weatherley 1968), whereas the other two plants were used for sampling of flag leaf tissue for RNA extraction. Terminal drought stress (D) was applied at inflorescence emergence stage (Zadoks 50-60), (Zadoks et al. 1974), after emergence of 1-2 spikes in all biological replicates of both genotypes. The time from transplanting to inflorescence emergence stage was not significantly different between genotypes (70 days in the S genotype and 72 days in the R genotype). Drought stress application initiated after irrigation with excess amount of water in order to assure that all pots start the experiment at the same soil water capacity. Drought stress was imposed by withholding water for eight days until stress symptoms (i.e. leaf rolling and wilting symptoms) were visible in plants of both genotypes. Stress symptoms were more visible in the S genotype, however, leaf relative water content (RWC), measured after eight days of drought stress was low but was not significantly different between the two genotypes (49.68%±1.48 in the R genotype and 53.34%±1.83 in the S genotype). The well-watered control (C) plants were irrigated daily by ample amount of water. Flag leaf tissues of drought-stressed plants and well-watered control plants were harvested, immediately frozen in liquid nitrogen, and stored at -80ºC for RNA extraction. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Krugman Tamar.

Project description:Soil fungal diversity under nitrogen and irrigation

Project description:NPI enriched more down-regulation genes involved in starch and sucrose metabolism, phenylpropanoid biosynthesis, amino sugar and nucleotide sugar metabolism, glycolysis/gluconeogenesis pathway, leading to restricted root growth. Three GO terms including channel activity, water transport, and water channel activity caused a high degree of gene enrichment. Thirteen genes related to water absorption and transport such as ZM00001D003006, ZM00001D014285 et al. were highly up-regulated, which might be the key genes for the significant increase in water use efficiency of maize under negative pressure irrigation.

Project description:After a standard cultivation program of six weeks, tomato plants (Solanum lycopersicum L.) cultivar MicroTom were grown under different conditions of atmospheric humidity and soil irrigation. The atmospheric humidity was adjusted to 40% and 80%, respectively. To regulate soil moisture, all potted plants were substrate saturated watered once a week. Furthermore, only a group of these plants was irrigated to assure optimally growing conditions (optimal watering conditions), whereas a second group had to cope with little water supply (no watering conditions). Mature green fruits were investigated (fruit developmental category II). Samples contained exclusively the fruit peel, which was removed with a scalpel to a depth of approximately 1 mm. After sampling point the plant material was immediately frozen in liquid nitrogen and stored at -80 C until use.
