Project description:au07-05_groundworms - groundworms - Do earthworms affect plant growth through signal molecules? - Plants were grown in a sandy soil from the Centre de Recherche en Ecologie Expérimentale et Prédictive (CEREEP, France), in the presence or absence of earthworms. Soil was dried and sieved at 2 mm before to be put in the pots. There was 2 levels of treatment (presence or absence of earthworms in the soil), and 5 plants per treatments.

Project description:The take-all disease caused by the soilborne fungus Gaeumannomyces graminis var tritici (Ggt) is one of the most-studied and widespread root diseases worldwide. Here, we investigated the ability of the earthworm Aporrectodea caliginosa to induce take-all disease tolerance in Triticum aestivum. In a greenhouse experiment, plants were grown in a sandy soil. Plants were inoculated or not with Ggt and in the presence or absence of earthworms. There was 4 levels of treatment (plants only, inoculated with Ggt, inoculated with earthworms or inoculated with earthworms and Ggt), and 2-3 plants per treatments.

Project description:Genome-wide transcriptome analysis was performed to understand the expression pattern of transcriptomes in tolerant and susceptible subtropical maize genotypes under waterlogging stress condition. Waterlogging stress causes yield reduction in maize (Zea mays). It is important to dissect the genetic circuits that underlie the plant responses to waterlogging. So, the experiment was designed with the following objectives: to understand the expression pattern of transcriptomes in the tolerant and the susceptible genotypes under waterlogging stress; to identify DEGs functioning in important pathways underlying adaptive traits; to co-map bin locations of the transcriptomes with already known QTLs for waterlogging and find synteny with other species; and to generate gene co-expression networks to study cohorts of genes expressed together in modules and functional cluster, while comparing the two genotypes. Two tropical maize (Zea mays L.) inbred lines, HKI1105 (tolerant) and V-372 (susceptible), were used for our experiment. The genotypes were sown in plastic pots filled with loam soil with sandy texture. The plants were watered daily to soil capacity until the application of stress at 28 days after sowing. To impose waterlogging condition, the perforation in the bottom of the pots (35 cm in height) was sealed and the stress treatment was given by watering the pots (5 cm standing water) for seven continuous days. To allow for recovery from stress, the perforations of the pots were unsealed for proper drainage of excess water. The root samples from both genotypes were collected on the 28th, 32nd, 35th and 42nd day after sowing, which represented control, moderate stress, severe stress and post-stress recovery stages, respectively. Two biological replications were used for each comparison.

Project description:Drought-responsive genes in soybean leaves were successfully identified using Affymetrix Soybean Gene 1.0 ST arrays on leaves samples of reproductive-stage soybean plants. R1 soybean plants planted in pots were imposed drought by withholding water for 5 days until the soil moisture content dropped to 5%, and 3rd trifoliates (now at the R2 stage) were collected for expression profiling.

Project description:The experiment was carried out during two vegetation seasons from 25th of April to 10th of September. Two Polish potato cultivars, the drought-tolerant Gwiazda and drought-sensitive Oberon were used. Selected tubers with transverse diameters of 3 - 4 cm were pre-sprouted for 2 weeks before planting. Plants were grown in a vegetation hall in pots filled with a thin layer of gravel on the bottom and the universal vegetable soil substrate ‘Hollas’ (Agaris Polska Ltd., Poland) produced from peat with the addition of chalk at a pH range of 5.5-6.5. Additionally, in phase 20 of the BBCH-scale of plant development, MIS-3 (Intermag) fertilizer was applied. Water content (WC) in volumetric basis in soil pots was measured according Black (1965). Weather conditions during the years of study were monitored using a Weather Campbell Station (Campbell Scientific Inc.) located in close proximity, and a thermohygrograph placed between pots. Meteorological data of air temperature, the photosynthetically active radiation, and humidity were comparable in the years of study and favorable for potato development. Three weeks after the initiation of the tuberisation phase (56 DAP), plants were divided into 3 groups, each consisting of 6 plants. The first group of plants was subjected to soil drought (remained without irrigation, day/night temperature 22°C/18°C), the second one to high temperature (day/night temperature 38°C/25°C) and the third one was watered according to needs and at optimal temperature (control plants, day/night temperature 22°C/18°C). Stress application lasted 14 days and finished at 70 DAP. During this period, plants were placed in phytotron equipped with six Hortilux Schreder Lamps with Philips light bulbs of 1600 W each. Air humidity was in the range 65-70%. WC under 14 days of soil drought reached 30% (v/v), and remained 80% (v/v) in control and high temperature conditions. During the recovery period, after 14 days of stress treatment, WC reached control levels. Plant root material for proteomic research was collected on the 14th day of stress treatment (70 DAP).

Project description:Arabidopsis plants were grown in plastic pots filled with peat moss for 3 weeks (principal growth stage 1.07-1.08) under a 16 h light/8 h dark regimen (40 ± 10 ?mol photons/m2/s) at 22 C.Dehydration treatment: The 3-week-old plants were grown for 2 or 3 days without watering. To obtain accurate results, we carefully raised single plants in Petri dishes, each containing an equal amount of soil. Soil moisture contents were calculated from soil dry weight. Untreated; the soil moisture content was 84.3%. Under dehydration, on the second day, the soil moisture content was 51.1%. Under dehydration, on the third day, the moisture content was 11.6%.

Project description:It has long been recognized that species occupy a specific ecological niche within their ecosystem. The ecological niche is defined as the number of conditions and resources that limit species distribution. Within their ecological niche, species do not exist in a single physiological state but in a number of states we call the Natural Operating Range. In this paper we link ecological niche theory to physiological ecology by measuring gene expression levels of collembolans exposed to various natural conditions. The soil-dwelling collembolan Folsomia candida was exposed to 26 natural soils with different soil characteristics (soil type, land use, practice, etc). The animals were exposed for two days and gene expression levels were measured. The main factor found to regulate gene expression was the soil type (sand or clay), in which 18.5% of the measured genes were differentially expressed. Gene Ontology analysis showed animals exposed to sandy soils experience general stress, affecting cell homeostasis and replication. Multivariate analysis linking soil chemical data to gene expression data revealed that soil fertility influences gene expression. Land-use and practice had less influence on gene expression; only forest soils showed a different expression pattern. A variation in gene expression variation analysis showed overall low variance in gene expression. The large difference in response to soil type was caused by the soil physicochemical properties where F. candida experiences clay soils and sandy soils as very different from each other. This collembolan prefers fertile soils with high organic matter content, as soil fertility was found to correlate with gene expression and animals exposed to sandy soils (which, in general, have lower organic matter content) experience more general stress. Finally, we conclude that there is no such thing as a fixed physiological state for animals in their ecological niche and the boundary between the ecological niche and a stressed state depends on the genes/pathways investigated.
