Gene expression profile of rice root in response to macronutrient deficiency
Ontology highlight
ABSTRACT: Macronutrients are pivotal elements for proper plant growth and development. We performed microarray analysis of rice root under nitrogen (N), phosphorus (P), and potassium (K) deficiency conditions to obtain a global view of gene regulations associated with plant response to essential nutrients.

Project description:Macronutrients are pivotal elements for proper plant growth and development. We performed microarray analysis of rice leaves under nitrogen (N), phosphorus (P), and potassium (K) deficiency conditions in paddy field to obtain a global view of gene regulations associated with plant response to essential nutrients.
Project description:Macronutrients are pivotal elements for proper plant growth and development. We performed microarray analysis of rice shoot under nitrogen (N), phosphorus (P), and potassium (K) deficiency conditions to obtain a global view of gene regulations associated with plant response to essential nutrients. We performed microarray analysis of rice shoot under N, P and K deficiency conditions (1/4, 1/16 and 1/64 of normal concentration) and control for each nutrient. We collected a total of 36 microarray data corresponding to 12 samples with 3 replicates.
Project description:Phosphorus (P) are pivotal element for proper plant growth and development. We performed microarray analysis of rice root under phosphorus deficiency (-P) to obtain a global view of gene regulations associated with plant response to -P.
Project description:Nitrogen (N) and phosphorus (P) are pivotal element for proper plant growth and development. We performed microarray analysis of rice shoot and root after nitrogen deficiency (-N) treatment under phosphorus deficiency (-P) condition to obtain a global view of gene regulations associated with plant response to -N under -P condition.
Project description:Phosphorus is one of the most important macronutrients required for plant growth and development. The importance of phosphorylation modification in regulating phosphate (Pi) homeostasis in plants is emerging. We performed phosphoproteomic profiling to characterize proteins whose degree of phosphorylation is altered in response to Pi starvation in rice root.
Project description:Endophytic fungi are root-inhabiting fungi that can promote plant growth in a variety of ways. They can directly stimulate plant growth by producing phytohormones, such as auxin and gibberellins. They can also indirectly promote plant growth by helping plants to acquire nutrients, such as nitrogen and phosphorus, and by protecting plants from pests and pathogens.In this study, we used a proteomic approach to identify the proteins that are expressed in rice plants after they are treated with endophytic fungi. We found that the treatment with endophytic fungi resulted in the expression of a number of proteins involved in plant growth, nutrient acquisition, and defense. These results suggest that endophytic fungi can promote plant growth and improve plant resilience to stress.
Project description:Potassium is one of the essential macronutrients required for plant growth and development. It plays a major role in different physiological processes like cell elongation, stomatal movement, turgor regulation, osmotic adjustment, and signal transduction by acting as a major osmolyte and component of the ionic environment in the cytosol and subcellular organelles. We used whole genome microarrays to determine the transcriptomic profile of rice seedlings exposed to short-term K+ deficiency followed by K+ resupply.
Project description:Nitrogen (N) are pivotal element for proper plant growth and development. We performed microarray analysis of rice shoot under nitrogen deficiency (-N) to obtain a global view of gene regulations associated with plant response to -N.
