Rescue of syringyl lignin and sinapate ester biosynthesis in Arabidopsis thaliana by a coniferaldehyde 5-hydroxylase from Eucalyptus globulus.

Prijava / prijava
CONCLUSIONS
The gene coding for F5H from Eucalyptus globulus was cloned and used to transform an f5h -mutant of Arabidopsis thaliana , which was complemented, thus verifying the identity of the cloned gene. Coniferaldehyde 5-hydroxylase (F5H; EC 1.14.13) is a cytochrome P450-dependent monooxygenase
Light, the circadian clock, and sugar perception in the control of lignin biosynthesis.

Prijava / prijava
Experiments were undertaken to investigate some of the mechanisms that may function to regulate lignin biosynthesis (lignification) in Arabidopsis thaliana. Northern blot analyses revealed that several genes encoding enzymes involved in the synthesis of lignin monomers displayed significant changes
PIRIN2 suppresses S-type lignin accumulation in a non-cell-autonomous manner in Arabidopsis xylem elements.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
PIRIN (PRN) genes encode cupin domain containing proteins that function as transcriptional co-regulators in humans but that are poorly described in plants. A previous study in xylogenic cell cultures of Zinnia elegans suggested a role for a PRN protein in lignification. This study aimed to identify
Patterned deposition of xylan and lignin is independent from the secondary wall cellulose of Arabidopsis xylem vessels.

Prijava / prijava
The secondary cell wall (SCW) of xylem vessel cells provides rigidity and strength that enables efficient water conduction throughout the plant. To gain insight into SCW deposition, we mutagenized Arabidopsis thaliana VASCULAR-RELATED NAC-DOMAIN7-inducible plant lines, in which ectopic protoxylem
The chromatin-modifying protein HUB2 is involved in the regulation of lignin composition in xylem vessels

Prijava / prijava
PIRIN2 (PRN2) was earlie rreported to suppress syringyl (S)-type lignin accumulation of xylem vessels of Arabidopsis (Arabidopsis thaliana). In the present study we report yeast-two hybrid results supporting the interaction of PRN2 with HISTONE MONOUBIQUITINATION2 (HUB2) in Arabidopsis. HUB2 has
Pinoresinol reductase 1 impacts lignin distribution during secondary cell wall biosynthesis in Arabidopsis.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Pinoresinol reductase (PrR) catalyzes the conversion of the lignan (-)-pinoresinol to (-)-lariciresinol in Arabidopsis thaliana, where it is encoded by two genes, PrR1 and PrR2, that appear to act redundantly. PrR1 is highly expressed in lignified inflorescence stem tissue, whereas PrR2 expression
The overexpression of the pine transcription factor PpDof5 in Arabidopsis leads to increased lignin content and affects carbon and nitrogen metabolism.

Prijava / prijava
PpDof 5 is a regulator of the expression of glutamine synthetase (GS; EC 6.3.1.2) genes in photosynthetic and non-photosynthetic tissues of maritime pine. We have used Arabidopsis thaliana as a model system to study PpDof 5 function in planta, generating transgenic lines overexpressing the pine
Expression of brown-midrib in a spontaneous sorghum mutant is linked to a 5'-UTR deletion in lignin biosynthesis gene SbCAD2.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Brown midrib (bmr) mutants in sorghum (Sorghum bicolor (L.) Moench) and several other C4 grasses are associated with reduced lignin concentration, altered lignin composition and improved cell wall digestibility, which are desirable properties in biomass development for the emerging lignocellulosic
Gene silencing of BnTT10 family genes causes retarded pigmentation and lignin reduction in the seed coat of Brassica napus.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Yellow-seed (i.e., yellow seed coat) is one of the most important agronomic traits of Brassica plants, which is correlated with seed oil and meal qualities. Previous studies on the Brassicaceae, including Arabidopsis and Brassica species, proposed that the seed-color trait is correlative to
Multiform biosynthetic pathway of syringyl lignin in angiosperms.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
To clarify the pathway for biosynthesis of sinapyl alcohol in angiosperms, tracer experiments using stable isotopes were performed on robinia ( Robinia pseudoacacia L.), oleander ( Nerium indicum Mill.), magnolia ( Magnolia kobus DC.) and Arabidopsis thaliana (L.) Heynh. Precursors used in the
Correlations between lignin content and structural robustness in plants revealed by X-ray ptychography.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Lignin is a heterogeneous aromatic polymer responsible for cell wall stiffness and protection from pathogen attack. However, lignin represents a bottleneck to biomass degradation due to its recalcitrance related to the natural cell wall resistance to release sugars for fermentation or further
A polyclonal antibody directed against syringylpropane epitopes of native lignins.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
With a view to visualizing the ultrastructural distribution of syringyl lignins in secondary plant cell walls, a polyclonal antibody raised from a synthetic DHP polymer consisting only of syringyl propane units was prepared. To test the reactivity of the antiserum, a mini-dot-blot immunoassay
Overexpression of a heterologous sam gene encoding S-adenosylmethionine synthetase in flax (Linum usitatissimum) cells: Consequences on methylation of lignin precursors and pectins.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
The Arabidopsis thaliana sam1 gene encoding S-adenosylmethionine synthetase (EC 2.5.1.6) was transferred to flax (Linum usitatissimum) cells via Agrobacterium tumefaciens. This enzyme catalyses the conversion of methionine to S-adenosylmethionine (SAM), the major methyl group donor in living cells.
Image analysis of stress-induced lignin deposition in Arabidopsis thaliana using the macro program LigninJ for ImageJ software.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
In vascular plants, lignin is deposited during morphogenesis but also under stress conditions. Assessing the degree of stress-induced lignin deposition is complicated because it occurs locally and irregularly in plant tissues. In this study, we developed a macro program, LigninJ, for the open-source
Effects of hypergravity environment on lignin formation in Arabidopsis.

Prijava / prijava
Lignin and the secondary wall formation are essential for evolution of land plants. In this study, effects of hypergravity environment on the morphology of the secondary wall and the lignin content were examined in Arabidopsis thaliana. Xylem vessels showed intense staining with phloroglucinol-HCl
