2. 1. Biosynthesis, interactions, and structure of native lignin

   Author : Ioanna Sapouna; Lauren S. McKee; Francisco Vilaplana; Claudia Crestini; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lignin; biomass valorization; extraction; tissue culture; lignin nanoparticles; wood aerogels; lignin; biomassavalorisering; extraktion; vävnadsodling; lignin nanopartiklar; trä aerogeler; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. READ MORE

4. 2. Cellular Aspects of Lignin Biosynthesis in Xylem Vessels of Zinnia and Arabidopsis

   Author : Henrik Serk; Edouard Pesquet; Simon Hawkins; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; tracheary elements; xylem wood; post-mortem lignification; non-cell autonomous process; xylem parenchyma; endoreplication; reactive oxygen species; laccases; peroxidases; molecular cell biology; molekylär cellbiologi;

   Abstract : Lignin is the second most abundant biopolymer on earth and is found in the wood (xylem) of vascular land plants. To transport the hydro-mineral sap, xylem forms specialized conduit cells, called tracheary elements (TEs), which are hollow dead cylinders reinforced with lateral secondary cell walls (SCW).

5. 3. New regulators of xylem lignification in arabidopsis

   Author : Bernadette Sztojka; Hannele Tuominen; Simon Hawkins; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Xylem; lignin; Arabidopsis; secondary cell wall; transcriptional regulation; lignin-biosynthetic gene; S G lignin ratio;

   Abstract : The ability of land plants to grow upright, bear their own weight and withstand adverse environmental conditions is largely dependent on the secondary xylem tissues of the stem. The xylem cells acquire thick secondary cell walls which are composed of cellulose, hemicellulose and lignin. READ MORE

6. 4. Investigation of genes and proteins involved in xylan biosynthesis

   Author : Anders Winzell; Ines Ezcurra; Johan Edqvist; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Populus; xylan biosynthesis; hemicellulose; glycosyltransferase; GT43; IRX; glycoside hydrolase; GH10; Xyn10A; CAZy; transcription factor; MYB; wood formation; secondary cell wall; Arabidopsis; Molecular biology; Molekylärbiologi;

   Abstract : Wood formation or xylogenesis is a fundamental process for so diverse issues as industry, shelter and a sustainable environment. Wood is comprised of secondary xylem, rigid large cells with thick cell walls that are lignified. READ MORE

7. 5. Biosynthesis of capsaicinoids by recombinant Saccharomyces cerevisiae

   Author : Nina Muratovska; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capsaicinoids; nonivamide; baker’s yeast; Capsicum; Saccharomyces cerevisiae; Pseudomonas putida; lignin-derived substrates; vanillin aminotransaminase; reductive amination; vanillylamine; N-Acyltransferase; CoA-ligase; amide; whole-cell bioconversion; TRPV1 receptor; ion channel; calcium dye Fluo-4; flow cytometry;

   Abstract : Throughout history, people have used products from different microorganisms and plants for many medicinal and nutritional applications. Chilli peppers have been used for spicing up food, but also for their pharmacological properties. READ MORE
