Project description:The microbial community and enzymes in fermented rice using defined microbial starter, containing Rhizopus oryzae, Saccharomycopsis fibuligera, Saccharomyces cerevisiae and Pediococcus pentosaceus, play an important role in quality of the fermented rice product and its biological activities including melanogenesis inhibitory activity. The microbial metaproteome revealed large-scale proteins expressed by the microbial community to better understand the role of microbiota in the fermented rice.

Project description:In this work, we used a functional gene microarray approach (GeoChip) to assess the soil microbial community functional potential related to the different wine quality. In order to minimize the soil variability, this work was conducted at a “within-vineyard” scale, comparing two similar soils (BRO11 and BRO12) previously identified with respect to pedological and hydrological properties within a single vineyard in Central Tuscany and that yielded highly contrasting wine quality upon cultivation of the same Sangiovese cultivar

Project description:In compatible interactions, biotrophic microbial phytopathogens rely on the supply of carbon and nitrogen assimilates by the colonized host tissue. Successful biotrophs need to reprogram host metabolism, which also involves the stimulation of assimilate export from living host cells into the plant-pathogen interface at the infection site. In rice and cassava, SWEET sucrose transporters, are induced by bacterial TAL (transcriptional activator-like) effectors to establish compatibility. A pathogen-specific transcriptional induction of SWEET transporters has also been observed in Arabidopsis leaves upon microbial challenge. Here, we have assessed the question, whether the phloem localized AtSWEET11 and AtSWEET12 transporters represent susceptibility factors in the interaction of Arabidopsis with the fungal hemibiotroph Colletotrichum higginsianum (Ch). Compared to wild type, sweet11/sweet12 double mutants exhibited priming of the SA pathway in mock conditions.

Project description:Tibet is one of the most threatened regions by climate warming, thus understanding how its microbial communities function may be of high importance for predicting microbial responses to climate changes. Here, we report a study to profile soil microbial structural genes, which infers functional roles of microbial communities, along four sites/elevations of a Tibetan mountainous grassland, aiming to explore potential microbial responses to climate changes via a strategy of space-for-time substitution. Using a microarray-based metagenomics tool named GeoChip 4.0, we showed that microbial communities were distinct for most but not all of the sites. Substantial variations were apparent in stress, N and C cycling genes, but they were in line with the functional roles of these genes. Cold shock genes were more abundant at higher elevations. Also, gdh converting ammonium into urea was more abundant at higher elevations while ureC converting urea into ammonium was less abundant, which was consistent with soil ammonium contents. Significant correlations were observed between N-cycling genes (ureC, gdh and amoA) and nitrous oxide flux, suggesting that they contributed to community metabolism. Lastly, we found by CCA, Mantel tests and the similarity tests that soil pH, temperature, NH4+–N and vegetation diversity accounted for the majority (81.4%) of microbial community variations, suggesting that these four attributes were major factors affecting soil microbial communities. Based on these observations, we predict that climate changes in the Tibetan grasslands are very likely to change soil microbial community functional structure, with particular impacts on microbial N cycling genes and consequently microbe-mediated soil N dynamics.

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.

Compared to wild type, sweet11/sweet12 double mutants exhibited priming of the SA pathway in mock conditions. To investigate transcriptional changes in C. higgsinanum infected leaves, five-week old Arabidopsis plants were spray infected with 2 Mio. conidia/ ml 1h before lights off and fully expanded leaves of wild type Col-0 and the sweet11/sweet12 double mutant were harvested in three situations: 1) immediately before treatment, 2) from mock treated plants (sprayed with water) at 2.5 days post treatment and 3) from C. higginsianum inoculated leaves during biotrophic colonization at 2.5 days post treatment
