Enhancement of growth by expression of poplar cellulase in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

To study the role of cellulose and cellulase in plant growth, we expressed poplar cellulase (PaPopCel1) constitutively in Arabidopsis thaliana. Expression increased the size of the rosettes due to increased cell size. The change in growth was accompanied by changes in biomechanical properties due to

The antibiotic peptaibol alamethicin from Trichoderma permeabilises Arabidopsis root apical meristem and epidermis but is antagonised by cellulase-induced resistance to alamethicin.

BACKGROUND Trichoderma fungi live in the soil rhizosphere and are beneficial for plant growth and pathogen resistance. Several species and strains are currently used worldwide in co-cultivation with crops as a biocontrol alternative to chemical pesticides even though little is known about the exact

A long-wavelength fluorescent substrate for continuous fluorometric determination of cellulase activity: resorufin-beta-D-cellobioside.

Numai utilizatorii înregistrați pot traduce articole

A simple and reliable continuous assay procedure for measurement of cellulase activity from several species using the new substrate resorufin-beta-D-cellobioside (Res-CB) has been developed. The product of enzyme reaction, resorufin, exhibits fluorescence emission at 585 nm with excitation at 571 nm

An Arabidopsis thaliana cDNA homologous to cellulase.

A cDNA containing an ORF encoding a protein homologous to cellulase has been isolated from an Arabidopsis cDNA library.

Two cellulases involved in litchi fruit abscission are directly activated by an HD-Zip transcription factor LcHB2.

Cellulases play important roles in the shedding of plant organs. However, little is yet known about the functions of cellulase genes during the process of organ abscission. Abnormal fruitlet abscission is a severe problem in the production of litchi, an economically important fruit widely grown in

Exogenous Cellulase Switches Cell Interdigitation to Cell Elongation in an RIC1-dependent Manner in Arabidopsis thaliana Cotyledon Pavement Cells.

Numai utilizatorii înregistrați pot traduce articole

Pavement cells in cotyledons and true leaves exhibit a jigsaw puzzle-like morphology in most dicotyledonous plants. Among the molecular mechanisms mediating cell morphogenesis, two antagonistic Rho-like GTPases regulate local cell outgrowth via cytoskeletal rearrangements. Analyses of several cell

Multiple endo-1,4-beta-D-glucanase (cellulase) genes in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

The plant cell wall is modified in coordination with almost all plant developmental processes. Modifications in the cell wall are thought to be mediated by cell wall hydrolases, including those encoded by a large family of genes specifying endo-1,4-beta-D-glucanases (EC 3.2.1.4), which participate

Toxic misfolding of Arabidopsis cellulases in the secretory pathway of Pichia pastoris.

Numai utilizatorii înregistrați pot traduce articole

Plants produce a large number of cellulases that are either secreted or anchored in the plasma membrane where they likely function in various aspects of cellulose synthesis, modification and degradation during plant growth and development. Very few of these enzymes have been characterized in any

Root cap specific expression of an endo-beta-1,4-D-glucanase (cellulase): a new marker to study root development in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

The sloughing of root cap cells from the root tip is important because it assists the growing root in penetrating the soil. Using a promoter-reporter (GUS) and RT-PCR analysis, we identified an endo-beta-1,4-glucanase (AtCel5) of Arabidopsis thaliana that is expressed exclusively in root cap cells

The Cellulase KORRIGAN Is Part of the Cellulose Synthase Complex.

Numai utilizatorii înregistrați pot traduce articole

Plant growth and organ formation depend on the oriented deposition of load-bearing cellulose microfibrils in the cell wall. Cellulose is synthesized by a large relative molecular weight cellulose synthase complex (CSC), which comprises at least three distinct cellulose synthases. Cellulose synthesis

Nucleotide polymorphisms in a pine ortholog of the Arabidopsis degrading enzyme cellulase KORRIGAN are associated with early growth performance in Pinus pinaster.

Numai utilizatorii înregistrați pot traduce articole

We have carried out a candidate-gene-based association genetic study in Pinus pinaster Aiton and evaluated the predictive performance for genetic merit gain of the most significantly associated genes and single nucleotide polymorphisms (SNPs). We used a second generation 384-SNP array enriched with

Early elicitor induction in members of a novel multigene family coding for highly related RING-H2 proteins in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

We describe the identification and structural characterization of a novel family of Arabidopsis genes related to ATL2 which encode a variant of the RING zinc finger domain, known as RING-H2. Analysis of genes selected by us and of sequences from Arabidopsis stored in databases permitted the

Callus cultures of Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

Protoplasts are plant cells lacking cell walls. They can be generated from stationary callus cultures derived from Arabidopsis thaliana seedlings. After treatment of the callus with cellulase and pectinase, protoplasts are inoculated with viral RNAs using polyethylene glycol. After various times

Controlled expression of pectic enzymes in Arabidopsis thaliana enhances biomass conversion without adverse effects on growth.

Numai utilizatorii înregistrați pot traduce articole

Lignocellulosic biomass from agriculture wastes is a potential source of biofuel, but its use is currently limited by the recalcitrance of the plant cell wall to enzymatic digestion. Modification of the wall structural components can be a viable strategy to overcome this bottleneck. We have

Synergistic effects of 2A-mediated polyproteins on the production of lignocellulose degradation enzymes in tobacco plants.

Numai utilizatorii înregistrați pot traduce articole

Cost-effective bioethanol production requires a supply of various low-cost enzymes that can hydrolyse lignocellulosic materials consisting of multiple polymers. Because plant-based enzyme expression systems offer low-cost and large-scale production, this study simultaneously expressed β-glucosidase
