Salt-induced growth reduction of plants is a well-known phenomenon which poses major problem in crop productivity in places where vast majority of land plants are affected by salt. In this report, studies were carried out to reveal the effect of salt injury on the cell division pattern in roots and the role of myo-inositol in preventing the salt-induced ion disequilibrium on the chromosome and DNA degradation in roots. Present study revealed induction of various chromosomal abnormalities on the… 

Cytogenetic effect of prolonged in vitro exposure of Allium cepa L. root meristem cells to salt stress

Differences of the action of excessive amounts of both tested salts at the cellular level were shown, as KCl induced higher frequencies of abnormalities during cell divisions, whereas NaCl showed more mitodepressive effect and more frequently led to the root meristem cell death.

Allium cepa root meristem cells under osmotic (sorbitol) and salt (NaCl) stress in vitro

Analysis of the action of iso-osmotic concentrations of NaCl (200 mM) and sorbitol (360 mM) showed stronger mitodepressive effects of salt stress in comparison to osmotic stress, which had a greater impact on cell shrinkage, while ionic stress perturbed cell functioning.

CYTOLOGICAL ANALYSIS OF ROOT TIPS AS A TOOL TO EVALUATE ABIOTIC STRESSES: AN APPLICATION WITH NaCl AND H2O2 TREATMENTS IN Allium cepa L

Usually, little attention is given to the consequences of abiotic stresses on cell division, cytological damage, and possible mutagenic and genotoxic effects. In this study, we tested a cytological

1 Salt stress induces non-CG methylation in coding regions 2 of barley seedlings ( Hordeum vulgare ) 3

Salinity can negatively impact crop growth and yield. Changes in DNA methylation are 29 known to occur when plants are challenged by stress and have been associated to the regulation of 30

Manipulation of inositol metabolism for improved plant survival under stress: a “network engineering approach”

It is proposed that engineering inositol metabolic network is a potential approach towards stress-tolerant transgenic crop plant generation and thus its exploitation in agricultural biotechnology is the call of time.

Salt Stress Induces Non-CG Methylation in Coding Regions of Barley Seedlings (Hordeum vulgare)

Identified markers have potential value as sentinels of salt stress and provide a starting point to allow understanding of the functional role of DNA methylation in facilitating barley’s response to this stressor.

Transcriptomic Profiling Analysis of Arabidopsis thaliana Treated with Exogenous Myo-Inositol

Investigation of differently expressed genes in one-month-old Arabidopsis seedling grown on MI free or MI supplemented culture medium showed that exogenous MI could alter gene expression and signaling transduction in plant cells, providing a systematic understanding of the functions ofExogenous MI in detail.

Interactive effect of potassium and spermidine protects growth, photosynthesis and chlorophyll biosynthesis in Vigna angularis from salinity induced damage by up-regulating the tolerance mechanisms

Pot experiments were conducted to evaluate the role of potassium (100 mg KCl / kg soil) and the spermidine (100 µM Spd) in regulation of growth, chlorophyll synthesis and photosynthesis in Vigna

Foliar Application of an Inositol-Based Plant Biostimulant Boosts Zinc Accumulation in Wheat Grains: A μ-X-Ray Fluorescence Case Study

There has been much interest in the incorporation of organic molecules or biostimulants into foliar fertilizers with the rationalization that these compounds will enhance the uptake, or subsequent

Salt Stress Induced Nuclear and DNA Degradation in Meristematic Cells of Barley Roots

Root growth of barley was inhibited by 200 raM NaCl, when 1 mM CaCl2 was present in the hydroponic culture solution, and nuclear degradation was accompanied by apoptosislike DNA fragmentation.

Salt stress-induced cell death in the unicellular green alga Micrasterias denticulata

Programmed cell death (PCD) is a key element in normal plant growth and development which may also be induced by various abiotic and biotic stress factors including salt stress. In the present study,

Salt Stress-induced Programmed Cell Death in Rice Root Tip Cells

It is concluded that salt can induce PCD in rice root tip cells, and it is proposed that in the early phase of riceroot tip cell PCD, salt stress-induced oxidative burst increased the antioxidant enzyme activity, which, in turn, scavenged the ROS and abrogated PCD.

Regulation of Cell-Specific Inositol Metabolism and Transport in Plant Salinity Tolerance

The model integrates the transcriptional control of a specialized metabolic pathway with physiological reactions in different tissues, which leads to a gradient of myo-inositol synthesis, supports root growth and sodium uptake and facilitates sodium sequestration and protecting photosynthesis.

Salt causes ion disequilibrium-induced programmed cell death in yeast and plants.

Evidence is presented that salt induces PCD in yeast and plants because of an ionic, rather than osmotic, etiology and both salt-sensitive mutants of yeast and Arabidopsis exhibit substantially more profound PCD symptoms, indicating that salt-induced PCD is mediated by ion disequilibrium.

Phosphoinositides and plant growth substance action.

The possibility that transient increases in the labelling of inositol phosphate fractions may be a result of increases in cytosolic Ca2+ levels needs to be addressed, and the possibility that polyphosphoinositidase activity to GTP-analogues may be involved is addressed.

Mannose induces an endonuclease responsible for DNA laddering in plant cells.

It appears that D-Man, a safe and readily accessible compound, offers remarkable features for the study of apoptosis in plant cells.

DNA fragmentation in cereal roots indicative of programmed root cortical cell death.

The characteristic DNA fragmentation found in the roots indicates programmed cell death with mechanistic similarities to apoptosis in wheat and barley, and appears to be more extensive in wheat than in barley roots.

Reduction in the level of intracellular myo-inositol in cultured soybean (Glycine max) cells inhibits cell division.

It is proposed that myo-inositol has a role in maintaining cell division in soybean callus tissue in suspension culture by making use of deoxyglucose to reduce intracellular levels ofMyo- inositol.

Adaptations to Environmental Stresses.

Investigating plants under stress can learn about the plasticity of metabolic pathways and the limits to their functioning, and questions of an ecological and evolutionary nature need investigation.
