Project description:Two potato cultivars, Russet Burbank and Bionta, were inoculated with three different endophytes containing different AHL types. The impact of the endophytes to the different cultivars was measured by gene expression analysis with a customized microarray B. phytofirmans type strain PsJN was originally isolated as a contaminant from surface-sterilized, Glomus vesculiferum-infected onion roots (Nowak et al., 1998), whereas strain P6 RG6-12 was isolated from the rhizosphere of a grassland in the Netherlands (Salles et al., 2006). This strain was selected based on its similarity to strain PsJN based on 16S rRNA gene homology, and similar phenotypic features. Both strains were generally cultivated on King's medium (King et al., 1954). For the mutant AHL to the strain B. phytofirmans PsJN a quorum quenching approach as described by Wopperer et al., 2006 was employed. Plasmid pMLBAD-aiiA, which contains aiiA, the Bacillus sp. 240B1 lactonase gene, was transferred to B. phytofirmans PsJN by triparental mating as described by de Lorenzo and Timmis (1994). 2 cultivars, 3 endophytes
Project description:Citrus disease resistance breeding has been advanced to introduce CTV resistance of trifoliate orange to citrus. Because the quality of the fruit of trifoliate ogate was low, backcross with citrus was necessary. In the case of citrus, it takes several years from flowering to obtaining next-generation seeds. Therefore, we generated transformants for the early flowering genes (citrus FLOWERING LOCUS T: CiFT) using CiFT co-expression vector construct and promoted generation. In Japan, it is difficult to plant transformants in the field. Therefore, it was decided to select null segregant lacking transgene from backcross progenies. In order to prove that the transgene has been completely removed, it is necessary to prove that no vector conract is present on the genome. Tthis matter was proved by CGH analysis.
Project description:Fruit ripening in Citrus is not well understood at the molecular level. Knowledge of the regulatory mechanism of citrus fruit ripening at the post-transcriptional level in particular is lacking. Here, we comparatively analyzed the miRNAs and their targeted genes in a spontaneous late-ripening mutant, ?Fengwan? sweet orange (MT) (Citrus sinensis L. Osbeck), and its wild-type counterpart ('Fengjie 72-1', WT). Using high-throughput sequencing of small RNAs and RNA degradome tags, we identified 107 known and 21 novel miRNAs, as well as 225 target genes. A total of 24 miRNAs (16 known miRNAs and 8 novel miRNAs) were shown to be differentially expressed between MT and WT. The expression pattern of several key miRNAs and their target genes during citrus fruit development and ripening stages was examined. Csi-miR156k, csi-miR159 and csi-miR166d suppressed specific transcription factors (GAMYBs, SPLs and ATHBs) that are supposed to be important regulators involved in citrus fruit development and ripening. In the present study, miRNA-mediated silencing of target genes was found under complicated and sensitive regulation in citrus fruit. The identification of miRNAs and their target genes provide new clues for future investigation of mechanisms that regulate citrus fruit ripening.

Project description:Analysis of effect of long-term cryopreservation on peripheral blood mononuclear cells at gene expression level. The hypothesis tested in the present study was that long-term cryopreservation has an influence on the transcriptome profile of peripheral blood mononuclear cells. Results indicated remarkable changes in expression patterns upon cryopreservation of PBMCs, with decreasing signal intensities over time. Total RNA obtained from isolated peripheral blood mononuclear cells of melanoma patients cryopreserved in liqiud nitrogen from 20 to 60 months.
