Project description:Ginsenosides are a class of natural product triterpene saponins and almost exclusively in the plant genus Panax which has a long history of use as dietary supplements. Pharmacological research demonstrated that ginsenosides have multiple bioactivities. Ginsenoside is produced at high levels within Panax japonicus, and we have performed Lable-free quantitaion analysis of multiple tissues from this species in order to investigate the biosynthetic genes required for producing ginsenoside.

Project description:Salvia is an important genus from the Lamiaceae with approximately 1000 species distributed globally. Several Salvia species are commercially important because of their medicinal and culinary properties. We report the construction of the first fingerprinting array for Salvia species enriched with polymorphic and divergent DNA sequences and demonstrate the potential of this array for fingerprinting several economically important members of this genus.

Project description:Hyperthermophilic bacteria of the genus Thermotoga are known to utilize a wide range of simple and complex polysaccharides. T. maritima's transcriptional response to a variety of mono- and poly-saccharides was previously studied to assign functions to genes involved in carbohydrate uptake and utilization. To compare and contrast closely-related members of the Thermotoga genus, a four-species microarray was developed by expanding a whole genome T. maritima array to include unique genes from three other species (T. neapolitana, T. petrophila, and T. sp. RQ2). This multi-species array was used to investigate the diversity of the genus, specifically the response of each of the four species to a mixture of polysaccharides (galactomannan, glucomannan, xylan, pectin, lichenan, and carboxymethyl cellulose).

Project description:Nitrogen is one of the essential elements for plant growth. NH4+ and NO3- are two major forms of absorbing element N for higher plants. In this study we found that the growth of Panax notoginseng is inhibited when only adding ammonium nitrogen fertilizer, and adding nitrate fertilizer can alleviate the toxicity caused by ammonium. We use RNA-seq to identify genes that are related to the alleviated phenotypes after introducing NO3- to Panax notoginseng roots under NH4+ stresses. Twelve RNA-seq profiles in four sample groups, i.e., control, samples treated with NH4+, samples treated with NO3- only, and treated with both NH4+ and NO3- were obtained and analyzed to identify deregulated genes in samples with different treatments. ACLA-3 gene is downregulated in NH4+ treated samples, but is upregulated in samples treated with NO3- and with both NH4+ and NO3-, which is further validated in another set of samples using qRT-PCR. Our results suggest that unbalanced metabolism of nitrogen and nitrogen is the main cause of ammonium poisoning in roots of Panax notoginseng, and NO3- may significantly upregulate the activity of ACLA-3 which subsequently enhances the citrate cycle and many other metabolic pathways in Panax notoginseng root. These potentially increase the integrity of the Panax notoginseng roots. Our results suggest that introducing NO3- fertilizer is an effective means to prevent the occurrence of toxic ammonium in Panax notoginseng root.

Project description:Phylogenetic, microbiological and comparative genomic analysis was used to examine the diversity among members of the genus Caldicellulosiruptor with an eye towards the capacity of these extremely thermophilic bacteria for degrading the complex carbohydrate content of plant biomass. Seven species from this genus (C. saccharolyticus, C. bescii (formerly Anaerocellum thermophilum), C. hydrothermalis, C. owensensis, C. kronotskyensis, C. lactoaceticus, and C. kristjanssonii) were compared on the basis of 16S rRNA phylogeny and cross-species DNA-DNA hybridization to a whole genome C. saccharolyticus oligonucleotide microarray. Growth physiology of the seven Caldicellulosiruptor species on a range of carbohydrates showed that, while all could be cultivated on acid pre-treated switchgrass, only C. saccharolyticus, C. besci, C. kronotskyensis, and C. lactoaceticus were capable of hydrolyzing Whatman No. 1 filter paper. Two-dimensional gel electrophoresis of the secretomes from cells grown on microcrystalline cellulose revealed that species capable of crystalline cellulose hydrolysis also had diverse secretome fingerprints. The two-dimensional secretome of C. saccharolyticus revealed a prominent S-layer protein that appears to be also indicative of highly cellulolytic Caldicellulosiruptor species, suggesting a possible role in cell-substrate interaction. These growth physiology results were also linked to glycoside hydrolase and carbohydrate-binding module inventories for the seven bacteria, deduced from draft genome sequence information. These preliminary inventories indicated that the absence of a single glycoside hydrolase family and carbohydrate binding motif family appear to be responsible for some Caldicellulosiruptor species’ diminished cellulolytic capabilities. Overall, the genus Caldicellulosiruptor appears to contain more genomic and physiological diversity than previously reported, and is well suited for biomass deconstruction applications.
