They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative...
After phloem loading, the sieve element-companion cell (SE–CC) complex moves sucrose from source to sink, and subsequent phloem unloading is crucial for assimilate allocation20,21. In plants that utilize an apoplasmic phloem unloading mode, the plasma membrane-localized Sugar Will Eventually be Exp...
Unless otherwise stated, an MS medium (Sigma, USA) without organic components, supplemented with 3% sucrose and 1% agar, and at a pH of 5.8 was applied for growing the wild-type and transgenic lines under sterile conditions at 23 °C with a 16-h light period. Identification of the T-...
There is described a process for the synthesis of a sucrose-6-ester comprising: (A) reacting a mixture comprising sucrose and a polar aprotic solvent with an organotin-based acylation promoter, while adding a solvent capable of removing water by co-distillation, and removing water by co-...
The composition of minimal salt medium per litre was: Na2HPO4 (2.0 g), KH2PO4 (1.0 g), ammonium oxalate (4.25 g), MgCl2 (0.4 g) and sucrose (50 mM). Trace elements composition for 1 L was: KI (0.05 g), LiCl (0.05 g), MnCl2·4H2O (0.8 g), H3BO3 (0.5 g), ZnCl2 (0.1 ...
Thirty-five injured larvae were transferred to a piece of wet filter paper dampened by minimum hemolymph-like solution (70 mM NaCl, 5 mM KCl, 1.5 mM CaCl2, 20 mM MgCl2, 10 mM NaHCO3, 5 mM trehalose, 115 mM sucrose, 5 mM Hepes, pH 7.2) (Stewart et al., 1994) in 35-mm plastic...
Find the empirical formula of a compound containing 40.6% carbon, 5.1% hydrogen and 54.2% oxygen. What is the empirical formula for acetic acid? What is the empirical formula for sucrose? What represents the empirical formula for A3B9? What is the empirical formula for propene, C3H6? What is...
an electrostatic interaction between both of them. In the presence of bacteria, invertase is released from the complex, as the cationic PEI-AgNPs bind to the anionic surface of bacteria, thus releasing invertase. The enzyme is then active to convert sucrose into glucose, a change that is ...
For immunohistochemistry, dissected gonads were fixed in 4% paraformaldehyde, cryo- preserved in 30% sucrose overnight at 4 °C and then embedded in Tissue-Tek OCT compound (Sakura Finetek), oriented, and stored at − 80 °C. Cryosections were cut at a thickness of 12 µ...
Compound (Sakura Finetek) for 30 min in a dark environment to replace the sucrose, and then embedded in O.C.T. at − 20 °C. Ten-micrometre brain sections were cut using a cry- ostat (Thermo SME, USA). The sections were stained by 4′ ,6-diamidino-2-phenylindole, and...
