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

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

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.

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

Cloning and characterization of elongation specific endo-1,4-beta-glucanase (cel1) from Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

The isolation of an elongation-specific endo-1,4-beta-glucanase-cel1 from Arabidopsis thaliana was made possible by the fact that considerable homology exists between different endo-1,4-beta-glucanase (EGase) genes from different plants. Degenerate primers were synthesized based on two conserved

Extreme Thermophilic Enzyme CelB-m Efficiently Degrades the Cellulose in Transgenic Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Agricultural and forestry wastes abundant in the plant biomass are an important resource of green energy. However, little is known about how to exploit efficiently the resource. In this study, we isolated the CelB gene that encodes the extremely thermophilic cellulose-degrading enzyme from

Identifying Stable Fragments of Arabidopsis thaliana Cellulose Synthase Subunit 3 by Yeast Display.

Numai utilizatorii înregistrați pot traduce articole

Determining structures of large, complex proteins remains challenging, especially for transmembrane proteins, as the protein size increases. Arabidopsis thaliana cellulose synthesis complex is a large, multimeric complex located in the plant cell membrane that synthesizes cellulose microfibrils in

A novel method for regenerating plants from mesophyll protoplasts of Arabidopsis thaliana line WS.

Numai utilizatorii înregistrați pot traduce articole

A procedure has been developed for the successful regeneration of plants from mesophyll protoplasts of Arabidopsis thaliana line WS. The protocol is an improved version of that of Damm and Willmitzer (1988).The main changes in original procedure are as follows: (1) A mixture of Cellulase Y-C (0.5%)

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

Numai utilizatorii înregistrați pot traduce articole

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

Expression of endo-1,4-beta-glucanase (cel1) in Arabidopsis thaliana is associated with plant growth, xylem development and cell wall thickening.

Numai utilizatorii înregistrați pot traduce articole

Arabidopsis thaliana CEL1 protein was detected in young expanding tissues. Immunostaining revealed that CEL1 accumulated mostly in xylem cells. The primary, as well as the secondary xylem showed considerable CEL1 staining. CEL1 was also observed in young epidermal cells, in which the thicker lateral

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

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

Causal Enzymology and Physiological Aspects May Be Accountable to Membrane Integrity in Response to Salt Stress in Arabidopsis thaliana Lines.

Numai utilizatorii înregistrați pot traduce articole

Apart from their significance in the protection against stress conditions, the plant cell membranes are essential for proper development of the diverse surface structures formed on aerial plant organs. In addition, we signal that membrane remodeling and integrity are function of some of causal

Arabidopsis thaliana KORRIGAN1 protein: N-glycan modification, localization, and function in cellulose biosynthesis and osmotic stress responses.

Numai utilizatorii înregistrați pot traduce articole

Plant cellulose biosynthesis is a complex process involving cellulose-synthase complexes (CSCs) and various auxiliary factors essential for proper orientation and crystallinity of cellulose microfibrils in the apoplast. Among them is KORRIGAN1 (KOR1), a type-II membrane protein with multiple
