Altered apoplastic ascorbate redox state in tobacco plants via ascorbate oxidase overexpression results in delayed dark-induced senescence in detached leaves.

Numai utilizatorii înregistrați pot traduce articole

Ascorbate oxidase (AO) is an apoplastic enzyme that uses oxygen to catalyse the oxidation of ascorbate (AA) to dehydroascorbate (DHA) via the unstable radical monodehydroascorbate (MDHA). Here, we report that transgenic tobacco plants (Nicotiana tabacum L. cv. Xanthi) with an in vivo lowered

Movement Protein of Cucumber Mosaic Virus Associates with Apoplastic Ascorbate Oxidase.

Numai utilizatorii înregistrați pot traduce articole

Plant viral movement proteins facilitate virion movement mainly through interaction with a number of factors from the host. We report the association of a cell wall localized ascorbate oxidase (CsAO4) from Cucumis sativus with the movement protein (MP) of Cucumber mosaic virus (CMV). This was

cDNA cloning and gene expression of ascorbate oxidase in tobacco.

A cDNA clone for ascorbate oxidase (AAO) has been isolated from a cDNA library of tobacco (Nicotiana tabacum) cells. The identity of the amino acid sequence deduced from tobacco AAO cDNA to that from pumpkin AAO cDNA was 68%, which was much lower than the identity (80%) between pumpkin and cucumber

Cloning and Functional Analysis of the Promoter of an Ascorbate Oxidase Gene from Gossypium hirsutum.

Apoplastic ascorbate oxidase (AO) plays significant roles in plant cell growth. However, the mechanism of underlying the transcriptional regulation of AO in Gossypium hirsutum remains unclear. Here, we obtained a 1,920-bp promoter sequence from the Gossypium hirsutum ascorbate oxidase (GhAO1) gene,

Expansion of transgenic tobacco protoplasts expressing pumpkin ascorbate oxidase is more rapid than that of wild-type protoplasts.

When pumpkin (Cucurbita spp., cv. Ebisu Nankin) ascorbate oxidase cDNA was introduced into cultured cells of tobacco BY-2 (Nicotiana tabacum L. cv. Bright Yellow No. 2) by Agrobacterium-mediated transformation, the transgenic cells expressed and secreted the recombinant pumpkin ascorbate oxidase

Ascorbate oxidase-dependent changes in the redox state of the apoplast modulate gene transcript accumulation leading to modified hormone signaling and orchestration of defense processes in tobacco.

Numai utilizatorii înregistrați pot traduce articole

The role of the redox state of the apoplast in hormone responses, signaling cascades, and gene expression was studied in transgenic tobacco (Nicotiana tabacum) plants with modified cell wall-localized ascorbate oxidase (AO). High AO activity specifically decreased the ascorbic acid (AA) content of

Altered stomatal dynamics in ascorbate oxidase over-expressing tobacco plants suggest a role for dehydroascorbate signalling.

Numai utilizatorii înregistrați pot traduce articole

Control of stomatal aperture is of paramount importance for plant adaptation to the surrounding environment. Here, we report on several parameters related to stomatal dynamics and performance in transgenic tobacco plants (Nicotiana tabacum L., cv. Xanthi) over-expressing cucumber ascorbate oxidase

Over-expression of ascorbate oxidase in the apoplast of transgenic tobacco results in altered ascorbate and glutathione redox states and increased sensitivity to ozone.

Numai utilizatorii înregistrați pot traduce articole

Transgenic tobacco ( Nicotiana tabacum L. cv. Xanthi) plants expressing cucumber ascorbate oxidase (EC.1.10.3.3) were used to examine the role of extracellular ascorbic acid in mediating tolerance to the ubiquitous air pollutant, ozone (O(3)). Three homozygous transgenic lines, chosen on the basis

Effect of ascorbate oxidase over-expression on ascorbate recycling gene expression in response to agents imposing oxidative stress.

Numai utilizatorii înregistrați pot traduce articole

Ascorbate oxidase (AO) is a cell wall-localized enzyme that uses oxygen to catalyse the oxidation of ascorbate (AA) to the unstable radical monodehydroascorbate (MDHA) which rapidly disproportionates to yield dehydroascorbate (DHA) and AA, and thus contributes to the regulation of the AA redox

The function of ascorbate oxidase in tobacco.

Numai utilizatorii înregistrați pot traduce articole

The function of the apoplastic enzyme ascorbate oxidase (AO) was investigated in tobacco (Nicotiana tabacum). The abundance of AO mRNA was up-regulated by light. Cytosolic ascorbate peroxidase (APX1) transcripts were also highest in the light. In contrast, L-galactono-gamma-lactone dehydrogenase,

Characterization of a pollen-specific cDNA clone from Nicotiana tabacum expressed during microgametogenesis and germination.

Numai utilizatorii înregistrați pot traduce articole

This report describes the isolation and characterization of a cDNA clone representing a gene specifically expressed in pollen. A cDNA library was constructed against mRNA from mature pollen of Nicotiana tabacum. It was screened differentially against cDNA from mRNA of leaf and of pollen. One clone,

A Novel Gene, OZONE-RESPONSIVE APOPLASTIC PROTEIN1, Enhances Cell Death in Ozone Stress in Rice.

Numai utilizatorii înregistrați pot traduce articole

A novel protein, OZONE-RESPONSIVE APOPLASTIC PROTEIN1 (OsORAP1), was characterized, which was previously suggested as a candidate gene underlying OzT9, a quantitative trait locus for ozone stress tolerance in rice (Oryza sativa). The sequence of OsORAP1 was similar to that of ASCORBATE OXIDASE (AO)

Redox Control of Aphid Resistance through Altered Cell Wall Composition and Nutritional Quality.

Numai utilizatorii înregistrați pot traduce articole

The mechanisms underpinning plant perception of phloem-feeding insects, particularly aphids, remain poorly characterized. Therefore, the role of apoplastic redox state in controlling aphid infestation was explored using transgenic tobacco (Nicotiana tabacum) plants that have either high (PAO) or low
