Project description:A greenhouse experiment was conducted at the Federal University of Alagoas in Maceio, Brazil. One-eye sett of sugarcane was planted in 20 liters plant pots, arranged in a completely randomized design and cultivated for 5 months before water privation.

Project description:<p>While irrigation and fertilization are basic cultivation practices in poplar plantations on a global scale, the impact of these practices on the environment is not well understood. Here, we demonstrate that water-urea coupling and water-compound fertilizer coupling differentially impact soil ecosystems. We report that water-fertilizer coupling did not significantly alter taxonomic diversity indices (richness, evenness), but it did drive significant shifts in microbial community composition, reflected by changes in the relative abundance of specific taxa (e.g., core phyla) and their functional profiles. Water-urea coupling reduced Proteobacteria and Actinobacteria in non-rhizosphere soils while increasing Acidobacteria and Chloroflexi. In contrast, water-compound fertilizer coupling amplified Proteobacteria and Actinobacteria dominance in rhizosphere soils. Water-fertilizer coupling reshaped microbial composition and functional gene abundance linked to nitrogen and sulfur cycling, indicating a potential shift in microbial-mediated N and S transformation processes. Water-urea treatment enriched denitrification genes and dissimilatory nitrate reduction genes (napABC) in rhizosphere soil, while water-compound fertilizer treatment enhanced nitrification (amoABC, HAO) and denitrification gene abundance in both soils. For sulfur (S) cycling, water-urea treatment favored thiosulfate oxidation genes (SOX complex), whereas water-compound fertilizer treatment increased assimilatory sulfate reduction genes. Multi-omics integration linked these microbial dynamics to metabolic reprogramming—water-urea increased lipid and secondary metabolites in rhizosphere soils, while water-compound fertilizers elevated amino acid-associated metabolites in non-rhizosphere soils.</p>

Project description:Summary The expression profile of internodes from high brix plant was compared to internodes from low brix plants. Mature (In9), intermediate (In5) and immature internodes (In1) were collected from two different Progenies and immediately frozen in liquid nitrogen. Total RNA was extracted using Trizol. Progeny 1 was derived from two intra-specific polycrosses, one among Saccharum officinarum genotypes and the other combining Saccharum spontaneum genotypes. For each generation, 500 individuals were sampled for brix content and gene expression. The extreme segregants were selected for further analysis. The F3 hybrid individuals selected for molecular studies were planted in a field in single rows of 5 m using standard sugarcane cultivation practices. Brix readings and tissue samples were collected very early in the season, and in March of the following year, when plants were 10 months old. The soluble solids (brix) content of mature internodes of each sugarcane stalk was measured with a portable refractometer (N1 model, ATAGO, Japan). Individuals or pools of eight individuals had their tissues collected and RNA extracted. Progeny 2 was derived from a cross between two commercial varieties (SP80-180 x SP80-4966). Five hundred sugarcane F1 plants were field-grown. The stem sugar content from the different plants showed a normal distribution, and seven plants with extreme brix values were collected.

Keywords: Expression profiling by array Total RNA from internodes pool from high brix plants and low brix plants was hybridized to dual channel arrays. Internodes from the same stage of development and from the same progeny were compared. The quantification of each hybridization was submitted in two files, one for each slide side (technical replicates).

Project description:Plants and rhizosphere microbes rely closely on each other, with plants supplying carbon to bacteria in root exudates, and bacteria mobilizing soil-bound phosphate for plant nutrition. When the phosphate supply becomes limiting for plant growth, the composition of root exudation changes, affecting rhizosphere microbial communities and microbially-mediated nutrient fluxes. To evaluate how plant phosphate deprivation affects rhizosphere bacteria, Lolium perenne seedlings were root-inoculated with Pseudomonas aeruginosa 7NR, and grown in axenic microcosms under different phosphate regimes (330 uM vs 3-6 uM phosphate). The effect of biological nutrient limitation was examined by DNA microarray studies of rhizobacterial gene expression.

Project description:Carbon (C) and nitrogen (N) contents of grain-filling stage are keys item that determined the growth of rice, and also the quality of seed. Therefore, to elucidating the mechanism of C/N signaling in a seed is an important problem for crops whose seed is used as food like rice. The DNA microarray analysis with the rice seed which was performed the additional fertilizer at the time of heading, in order to clarify how C/N signal change of the rhizosphere in seed production stage affects a seed component on a gene expression level.
