“…The effects of rare sugars have recently been investigated. For example, D-allose and Dpsicose have been shown to induce disease resistance in rice and lettuce (Kano et al, 2010;2013;Ishida et al, 2012). Ishida et al (2011) demonstrated that D-tagatose reduced the flower-setting node order of morning glories, and accelerated flower bud differentiation in strawberries.…”

Plant materials and growth conditions Tomatoes (Solanum lycopersicum L., cv. Momotaro 8; Takii Seed Co., Ltd., Japan) were grown in a greenhouse with acrylic panels. The temperature was maintained within the range 15 35°C. Tomato plugs were grown in rockwool cubes (75 mm 75 mm 65 mm, Delta 4G, Grodan, Netherlands) and transplanted to rockwool slabs (900 mm 195 mm 75 mm; Grotop Master 2075 A1W, Grodan, Netherlands) when the first truss was visible. The plants were fertilized with a half-strength Otsuka-A solu

“…The high levels of D-psicose in DPs suggest a need of sugar for constructing apoplast polysaccharides. It is obvious that this anabolic behavior inhibits respiration and regulate plant growth, a fact frequently associated to stress resistance induction by D-psicose (Kudo et al 2010;Ishida et al 2012). Nevertheless, the presence of psicose was also associated to the mother vitroplant as this metabolite was not detected in M2 DPs.…”

“…The only monosaccharide signi cantly accumulated in DPs was D-psicose. This is a rare hexose that inhibits the enzymes related to the hydrolysis of higher saccharides (Hossain et al 2015) and has been associated with an increase in plant sugar content (Ishida et al 2012). The high levels of D-psicose in DPs suggest a need of sugar for constructing apoplast polysaccharides.…”

BackgroundMicropropagation techniques allow the mass production of pathogen-free banana plants but can cause somaclonal variations (SV) such as dwarfism. Changes in the metabolite profile during micropropagation of true-to-type (normal) and dwarf banana plants have not been described. Normal and dwarf banana Musa AAA cv. “Williams” were micropropagated and the metabolite profile of vitroplants was assessed at the proliferation, rooting and greenhouse-acclimatization phases of tissue culture. Metabolites from 10 dwarf and 10 normal meristems from each micropropagation phase were extracted and detected by gas chromatography coupled to mass spectrometry (GC-MS). Principal component analysis (PCA) and test of statistical significance were applied to detect differentially expressed metabolites. ResultsThe PCA showed a clear grouping of the dwarf plants (DPs) separated from the normal plants (NPs) in the rooting and acclimatization phases. In the proliferation phase, L-sorbose was significantly more abundant in DPs when compared to NPs. In the rooting phase, the aerial parts of the DPs showed significantly higher levels of 2-Keto-d-gluconic and citric acids but lower levels of fructose when compared to NPs. The meristems of DPs from the acclimatization phase showed significantly higher levels of D-galactose, gulonic acid and D- galacturonic acid but lower levels of mannose and L-fucose when compared to the NPs. Some molecules, such as L-glutamin and uridin were only detected in NPs from this phase. ConclusionsResults suggest the presence of oxidative stress and changes in the constitution of the apoplast at the different stages potentially affecting cell shape and phenotypic traits in DPs.

“…2 Despite their limited accessibility, rare ketoses offer a lot of potential for applications in pharmaceutical, medicinal, food, and synthetic chemistry. 3 For example, D-psicose has about 70% of the sweetness but only 0.3% of the energy calories of sucrose. 4 It can also inhibit hepatic lipogenous enzyme activity, helping reduce abdominal fat accumulation.…”

L-rhamnulose (6-Deoxy-L-arabino-2-hexulose) and L-fuculose (6-Deoxy-L-lyxo-2-hexulose) were prepared from L-rhamnose and L-fucose by a two-step strategy. In the first reaction step, isomerization of L-rhamnose to L-rhamnulose, or L-fucose to L-fuculose was combined with a targeted phosphorylation reaction catalyzed by L-rhamnulose kinase (RhaB). The by-products (ATP and ADP) were selectively removed by silver nitrate precipitation method. In the second step, the phosphate group was hydrolyzed to produce L-rhamnulose or L-fuculose with purity exceeding 99% in more than 80% yield (gram scale).
