Project description:Intercropping is a vital technology in resource-limited agricultural systems with low inputs. Peanut/maize intercropping enhances iron (Fe) nutrition in calcareous soil. Proteomic studies of the differences in peanut leaves, maize leaves and maize roots between intercropping and monocropping systems indicated that peanut/maize intercropping not only improves Fe availability in the rhizosphere but also influences the levels of proteins related to carbon and nitrogen metabolism. Moreover, intercropping may enhance stress resistance in the peanut plant (Xiong et al. 2013b). Although the mechanism and molecular ecological significance of peanut/maize intercropping have been investigated, little is known about the genes and/or gene products in peanut and maize roots that mediate the benefits of intercropping. In the present study, we investigated the transcriptomes of maize roots grown in intercropping and monocropping systems by microarray analysis. The results enabled exploration differentially expressed genes in intercropped maize. Peanut (Arachis hypogaea L. cv. Luhua14) and maize (Zea mays L. cv. Nongda108) seeds were grown in calcareous sandy soil in a greenhouse. The soil was enhanced with basal fertilizers [composition (mg·kg−1 soil): N, 100 (Ca (NO3)2·4H2O); P, 150 (KH2PO4); K, 100 (KCl); Mg, 50 (MgSO4·7H2O); Cu, 5 (CuSO4·5H2O); and Zn, 5 (ZnSO4·7H2O)]. The experiment consisted of three cropping treatments: peanut monocropping, maize monocropping and intercropping of peanut and maize. After germination of peanut for 10 days, maize was sown. Maize samples were harvested after 63 days of growth of peanut plants based on the degree of Fe chlorosis in the leaves of monocropped peanut. The leaves of monocropped peanut plants exhibited symptoms of Fe-deficiency chlorosis at 63 days, while the leaves of peanut plants intercropped with maize maintained a green color.

Project description:Intercropping is a sustainable agricultural practice widely used around the world for enhancing resource use efficiency. However, short crops often grow in shade condition underneath the canopy of tall crops. Soybean is one of the most important oil crops and usually is planted in intercropping patterns. However, little is known about the acclimation responses of soybean leaves to shade in intercropping condition at the transcriptome level.

Project description:The prevention or delay of brain senescence would enhance the quality of life for older persons. We investigated the effects of soybean extracts in senescence-accelerated (SAMP10) mice. This mouse is a model of brain senescence with a short life span, cerebral atrophy and cognitive dysfunction. Mice were fed a diet containing soybean extracts from 1 to 12 months of age. The effects of green and yellow soybean extracts were compared with a control diet without soybean extracts. Cognitive functions were higher in aged mice fed green soybean than age-matched control mice and mice fed yellow soybean. We further investigated transcriptome of the SAMP10 hippocampus indicated that expression levels of 36 genes were significantly higher and 19 genes were lower in mice that ingested green soybean than in mice that ingested yellow soybean. Some of the evidences were reconfirmed by real time PCR analysis; the levels of Cdh1 and Ptgds mRNA were significantly higher and that the level of Aplp1 was significantly lower in aged SAMP10 mice fed green soybean than mice ingested yellow soybean and control mice. Additionally, the amount of amyloid beta 40 and 42 was lower in the insoluble fraction of aged SAMP10 mice fed green soybean than control mice and mice fed yellow soybean, although the levels of amyloid beta 40 and 42 in the soluble fraction were not different. Lipocalin-type prostaglandin D2 synthase (L-PGDS) has been proposed as the endogenous amyloid beta - chaperone, suggesting that amyloid aggregation was lower in mice fed green soybean than control mice and mice fed yellow soybean. These results indicate that the intake of green soybean improved cognitive function in aged mice, and suppressed amyloid beta accumulation. Green soybean might help healthy aging of the brain in older persons.

Mice were fed a CE-2 diet containing 3.0% soybean extracts taken from both yellow and green soybean species, from 1 to 12 months of age. Total RNA was extracted from the stored hippocampus for DNA microarray analysis.
