“…For some phenolics and condensed tannins, a potential role in the O 3 tolerance has been claimed (Haikio et al 2009;Kontunen-Soppela et al 2007). Furthermore, in accordance with an increased level in phenolics, the induction of the shikimate and phenylpropanoid pathways shared by the flavonoid, anthocyanin, tannin, stilbene and lignin biosynthesis has been well documented under O 3 exposure (see Cabané et al 2012 for review). For some tree species that emit large amounts of VOCs, it is also interesting to consider the potential role of these compounds like antioxidants, as found for isoprene in poplar (Loreto et al 2001) and for monoterpenes in oak (Loreto et al 2004).…”

Abstract& Key message Ozone, one of the major atmospheric pollutants, alters tree growth, mainly by decreasing carbon assimilation and allocation to stems and roots. To date, the mechanisms of O 3 impact at the cellular level have been investigated mainly on young trees grown in controlled or semi-controlled conditions. In the context of climate change, it is necessary to introduce a valuable defence parameter in the models that currently predict O 3 impact on mature trees and the carbon sequestration capacity of forest ecosystems.

“…The authors reported also the presence of coniferin/CA in cell extracts obtained from CA treated cultures whereas in our studies coniferin/ CA was not detected in root cultures subjected to CA or CA, PHEN and MeJa treatments. Phenylpropanoids were reported to play an important role in plant response to abiotic (Cabane et al 2012) and biotic stresses (Dixon et al 2002;Naoumkina et al 2010) and the biosynthesis of CA was found to be induced as a result of wounding . Anterola et al (2002) reported that CA and p-coumaryl alcohol biosynthesis were enhanced with providing cell cultures of Pinus taeda with saturating amounts of PHEN and Cabane et al (2012) concluded that effective stimulation of phenylpropanoid pathway takes place when PHEN availability from the shikimate pathway is sufficient.…”

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.

“…[5,41,99,[145][146][147][148][149][150][151] The response of these pathways to abiotic stresses is crucial for understanding the full biological role of lignin in the plant. [5,145] Effects of abiotic stress can be analysed either by individually introducing stresses,e .g., growing the plant in amedium with high salinity), [150,152] or by monitoring how the plants perform in ag reenhouse setting vs.i nf ield trials. [153] Recent review literature provides ac omparison of the impacts of biotic and abiotic stress on plant fitness when transferring from ac ontrolled greenhouse environment to field trials.…”

Paving the Way for Lignin Valorisation: Recent Advances in Bioengineering, Biorefining and Catalysis

Lignin is an abundant biopolymer with a high carbon content and high aromaticity. Despite its potential as a raw material for the fuel and chemical industries, lignin remains the most poorly utilised of the lignocellulosic biopolymers. Effective valorisation of lignin requires careful fine‐tuning of multiple “upstream” (i.e., lignin bioengineering, lignin isolation and “early‐stage catalytic conversion of lignin”) and “downstream” (i.e., lignin depolymerisation and upgrading) process stages, demanding input and understanding from a broad array of scientific disciplines. This review provides a “beginning‐to‐end” analysis of the recent advances reported in lignin valorisation. Particular emphasis is placed on the improved understanding of lignin's biosynthesis and structure, differences in structure and chemical bonding between native and technical lignins, emerging catalytic valorisation strategies, and the relationships between lignin structure and catalyst performance.
