“…Pinoresinol is reduced through lariciresinol to secoisolariciresinol and eventually oxidized to matairesinol (Suzuki and Umezawa 2007). Coniferyl alcohol and p-coumaryl alcohol are the major building units of conifer lignin, a heterogeneous polymer deposited during cell differentiation and secondary cell wall formation (Marjamaa et al 2007;Wagner et al 2012).…”

The biosynthetic potential for six lignans accumulation in two lines of Taxus x media hairy roots was investigated. The cultures of KT and ATMA hairy root lines were supplemented with precursors: coniferyl alcohol (CA 1, 10 or 100 µM) and/or l-phenylalanine (100 µM PHEN) and/or methyl jasmonate (100 µM MeJa). Moreover the two-phase in vitro cultures supported with perfluorodecalin (PFD) as a gas carrier and in situ extrahent were used. The hairy root lines differed in lignan production profiles. In the control untreated cultures KT roots did not accumulate secoisolariciresinol and lariciresinol while ATMA roots did not accumulate matairesinol. In ATMA roots the treatment with CA (1 or 10 µM) resulted in the production of lariciresinol and secoisolariciresinol whereas solely lariciresinol was present after 100 µM CA application. Elicitation with 1 µM CA and MeJa yielded with hydroxymatairesinol aglyca and lariciresinol glucosides with their highest content 37.88 and 3.19 µg/g DW, respectively. The stimulatory effect of simultaneous treatment with 1 µM CA, PHEN and MeJa on lignan production was observed when the cultures were supplemented with PFD-aerated or degassed. In ATMA root cultures these applied conditions were the most favourable for matairesinol content which amounted to 199.86 and 160.25 µg/g DW in PFD-aerated and PFD-degassed supported cultures, respectively. In KT root cultures solely, hydroxymatairesinol and coniferin/CA content was enhanced with their highest yield 59.29 and 134.60 µg/g DW in PFD-aerated and PFD-degassed cultures, respectively.

“…These lignified thickenings have a reticulate, spiral, annular, scalariform, or pitted pattern, which is one of their most characteristic morphological features (Fukuda 1992;Höfte 2010). The patterned deposits of secondary wall in TEs primarily consist of polysaccharides (cellulose microfibrils and hemicelluloses) and lignin, a complex aromatic polymer (Turner et al 2007;Wagner et al 2012). These cell wall components result in a structure of great strength and resistance to degradation (Lacayo et al 2010).…”

“…Lignification and lignin manipulations performed with angiosperms and conifers have been reviewed by Boerjan et al (2003) and Wagner et al (2012) respectively. Sato et al (1997) isolated and characterised a novel peroxidase gene, ZPO-C, whose expression and function are closely associated with lignification during Zinnia TE differentiation.…”

“…Ito and Fukuda (2002) achieved the transformation of cultured Z. elegans cells with the Z. elegans endonuclease 1 (ZEN1) gene using a particle bombardment method. Pinus radiata xylogenic cell cultures can be transformed biolistically using a particle gun and subsequently used for testing of genes related to cell differentiation and cell-wall formation (Möller et al 2003;Wagner et al 2012). This cell culture system is very useful for functional genomics as it allows silencing and over-expression of candidate genes.…”

This review summarises two key aspects of in vitro plant tracheary element (TE) culture systems: establishment of in vitro TE systems and methods for analysing TEs, based on examples of in vitro TE systems in angiosperms and gymnosperms. A comparison between different TE systems suitable for various species and recent research studies are also presented along with a presentation of the issues and future challenges underlying in vitro TE systems.

Lignin ist ein reichlich vorhandenes Biopolymer mit hohem Kohlenstoffgehalt und hoher Aromatizität. Trotz seines Potenzials als Rohstoff für die Kraftstoffherstellung und die chemische Industrie ist Lignin noch immer das am wenigsten genutzte Biopolymer der Lignocellulose. Zur effektiven Aufwertung von Lignin ist eine sorgfältige Feinabstimmung mehrerer vorgeschalteter Prozessstufen (d. h. Biotechnik von Lignin, Abtrennung von Lignin und katalytische Umwandlung von Lignin in der Anfangsphase) und mehrerer nachgeschalteter Prozessstufen (d. h. Depolymerisation und Verwertung von Lignin) erforderlich, die den Einsatz und das Zusammenwirken eines breiten Spektrums wissenschaftlicher Disziplinen erfordert. Dieser Aufsatz liefert eine Analyse der neuesten Fortschritte bei der Verwertung von Lignin “vom Anfang bis zum Ende”. Besonderes Augenmerk liegt auf dem verbesserten Verständnis der Biosynthese und Struktur von Lignin, den Unterschieden in Struktur und chemischer Bindung zwischen nativen und technischen Ligninen, den neu aufkommenden Verfahren der katalytischen Verwertung und den Zusammenhängen zwischen Ligninstruktur und Katalysatorleistung.
