Fine genetic mapping of the TuNI locus causing systemic veinal necrosis by turnip mosaic virus infection in Arabidopsis thaliana.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
In the pathosystem of turnip mosaic virus (TuMV) and Arabidopsis thaliana, two distinct symptoms (mosaic symptom and veinal necrosis) were observed that were dependent upon the combination of the TuMV isolate and the Arabidopsis ecotype. The Col-0 ecotype developed mosaic symptoms after infection
Reactive oxygen species from chloroplasts contribute to 3-acetyl-5-isopropyltetramic acid-induced leaf necrosis of Arabidopsis thaliana.

3-Acetyl-5-isopropyltetramic acid (3-AIPTA), a derivate of tetramic acid, is responsible for brown leaf-spot disease in many plants and often kills seedlings of both mono- and dicotyledonous plants. To further elucidate the mode of action of 3-AIPTA, during 3-AIPTA-induced cell necrosis, a series of

Hybrid necrosis in plants arises from conflict between divergent alleles of immunity genes contributed by different parents, resulting in autoimmunity. We investigate a severe hybrid necrosis case in Arabidopsis thaliana, where the hybrid does not develop past the cotyledon stage and dies three
Novel allelic variants in ACD6 cause hybrid necrosis in local collection of Arabidopsis thaliana.

Hybrid necrosis is a common type of hybrid incompatibility in plants. This phenomenon is caused by deleterious epistatic interactions, resulting in spontaneous activation of plant defenses associated with leaf necrosis, stunted growth and reduced fertility in hybrids. Specific combinations of
Different mechanisms for Arabidopsis thaliana hybrid necrosis cases inferred from temperature responses.

Temperature is a major determinant of plant growth, development and success. Understanding how plants respond to temperature is particularly relevant in a warming climate. Plant immune responses are often suppressed above species-specific critical temperatures. This is also true for intraspecific

Genetic and molecular analyses of an Arabidopsis thaliana mutant with necrotic cotyledons from the collection of insertion mutants obtained earlier were conducted. The mutation under study showed incomplete dominance and represented a single insertion of the T region of pLD3 vector used for
Arabidopsis thaliana deficient in two chloroplast ascorbate peroxidases shows accelerated light-induced necrosis when levels of cellular ascorbate are low.

Arabidopsis chloroplasts have a multi-layered defense against hydrogen peroxide (H(2)O(2)) that includes a stromal and thylakoid ascorbate peroxidase (sAPX and tAPX). Single and double null mutants in SAPX and TAPX (sapx and tapx) were each crossed with ascorbate deficient vtc2. The single, double

Recently we have cloned and characterized a novel, oxidative stress-induced Arabidopsis thaliana gene (oxy5), and showed that expression of oxy5 protects bacterial cells from death caused by oxidative stress. As oxidative stress is one pathway of TNF cytotoxicity, we investigated whether the encoded

Necrosis plays a fundamental role in plant physiology and pathology. When plants or plant cell cultures are subjected to abiotic stress they initiate rapid cell death with necrotic morphology. Likewise, when plants are attacked by pathogens, they develop necrotic lesions, the reaction known as
HpaP sequesters HrpJ, an essential component of Ralstonia solanacearum virulence that triggers necrosis in Arabidopsis.

The Gram-negative bacterium Ralstonia solanacearum, the causal agent of bacterial wilt, is a worldwide major crop pathogen whose virulence strongly relies on a type III secretion system (T3SS). This extracellular apparatus allows the translocation of proteins, called type III effectors
The P3 protein of turnip mosaic virus can alone induce hypersensitive response-like cell death in Arabidopsis thaliana carrying TuNI.

Strains TuR1 and TuC of Turnip mosaic virus (TuMV) induce different symptoms on Arabidopsis thaliana ecotype Landsberg erecta (Ler); plants infected with TuR1 develop systemic necrosis, while TuC causes mosaics. We previously found that the Ler systemic necrosis was controlled by a single dominant

ABSTRACT Botrytis cinerea is a necrotrophic fungus that infects over 200 plant species. Previous studies showed that host cells collapse in advance of the hyphae, suggesting secretion of toxins or elicitors. We have partially characterized elicitor activity from intercellular fluid extracted from

Alternanthera mosaic virus (AltMV) triple gene block 3 (TGB3) protein is involved in viral movement. AltMV TGB3 subcellular localization was previously shown to be distinct from that of Potato virus X (PVX) TGB3, and a chloroplast binding domain identified; veinal necrosis and chloroplast

In this study, mRNA profiles generated from cDNA microarrays were used to identify gene expression changes in Arabidopsis thaliana ecotype Shahdara infected with Tobacco mosaic virus (TMV). Shahdara is a susceptible TMV host, permitting rapid accumulations of virus in both inoculated and systemic

Cellular redox status plays critical roles in cell division and differentiation, but the underlying mechanism is unclear. Here we explored the effect of redox status on stem cell identity in distal stem cells (DSCs) of Arabidopsis thaliana roots. Treatment with the reductive reagent glutathione
