Project description:Improvement of phosphorus (P) uptake by crops is a prerequisite for sustainable agriculture. Rice (Oryza sativa L.) PHOSPHORUS-STARVATION TOLERANCE 1 (OsPSTOL1) increases root growth and total P uptake. Here, a biogeographic survey of rice demonstrates OsPSTOL1 loss in a subset of japonica rice after the temperate-tropical split and frequent absence in paddy varieties of east Asia. OsPSTOL1 absence or loss-of-function alleles prevail in landraces from regions with fertilizer use and controlled irrigation, suggesting it is an adaptive genetic variant in low nutrient rainfed ecosystems. OsPSTOL1 is a truncated member of a family of multi-module kinases associated with microbial interactions. We demonstrate that ectopic expression of OsPSTOL1 in wheat (Triticum aestivum L.) increases shoot and root growth under low P conditions, promotes root plasticity, and hastens induction of the low P response pathway. OsPSTOL1’s influence on adaptive root development in wheat validates its potential for broad utilization in crop improvement.

Project description:Purpose: To understand the effects of two different chemical forms of iron fertilizer on cadmium accumulation Methods:Cultivation and treatment for three weeks of dwarf Polish wheat seedlings by hydroponics, in triplicate, qRT–PCR validation was performed using TaqMan and SYBR Green assays Results: Iron fertilizer can effectively reduce cadmium concentration in plants Conclusions: Our study represents the different chemical forms of iron fertilizer have different mitigation effects on cadmium. The transcriptome gata showed that iron fertilizer have changed the cadimium metabolism

Project description:Paddy rice with husk can be availbale for chicken dietary resource instead of yellow corn. Ingestion of paddy rice potentially affects on gastrointestinal physiology and function including digestion/absorption of nutrients and gut barrier function such as mucosal immunity, but the details of changes is unknown. To obtain insight into the physiological modifications in the small intestine of chickens fed paddy rice, we conducted a comprehensive analysis of gene expression in small intestine by DNA microarray. In the paddy rice group, a total of 120 genes were elevated >1.5-fold in the paddy rice group, whereas a total of 159 genes were diminished < 1.5-fold. Remarkably, the gene expression levels of IGHA (immunoglobulin heavy chain α), IGJ (immunoglobulin J chain), and IGLL1 (immunoglobulin light chain λ chain region), which constitute immunoglobulin A, decreased 3 to 10 times in the paddy rice group.

Project description:Microbes play key roles in diverse biogeochemical processes including nutrient cycling. However, responses of soil microbial community at the functional gene level to long-term fertilization, especially integrated fertilization (chemical combined with organic fertilization) remain unclear. Here we used microarray-based GeoChip techniques to explore the shifts of soil microbial functional community in a nutrient-poor paddy soil with long-term (21 years).The long-term fertilization experiment site (set up in 1990) was located in Taoyuan agro-ecosystem research station (28°55’N, 111°27’E), Chinese Academy of Sciences, Hunan Province, China, with a double-cropped rice system. fertilization at various regimes.
