Programmed cell death (PCD), the highly regulated dismantling of cells, is essential for plant growth and survival. PCD plays key roles in embryo development, formation and maturation of many cell types and tissues, and plant reaction/adaptation to environmental conditions. Reactive oxygen species (ROS) are not only toxic by products of aerobic metabolism with strictly controlled cellular level...
Mycotoxins are secondary fungal metabolites, toxic to humans, animals and plants. Among the hundreds of known mycotoxins, aflatoxins, citrinin, patulin, penicillic acid, tenuazonic acid, ochratoxin A, cytochalasins, deoxynivalenol, fumonisins, fusarin C, fusaric acid, and zearalenone are considered the types that most contaminate cereal grain. The majority of the mycotoxins in these groups are ...
Toxic plants such as Delphinium spp. (i.e., larkspur) are a significant cause of livestock losses worldwide. Correctly determining the causative agent responsible for the death of an animal, whether by disease, poisonous plant, or other means, is critical in developing strategies to prevent future losses. The objective of this study was to develop an alternative diagnostic tool to microscopy an...
Certain decorative indoor-plant cultivars are derived from toxic wild plant species. Native members of the Euphorbiaceae (spurge) contain highly irritating and tumor-promoting diterpene esters. Plant breeders and gardeners are constantly searching for less toxic cultivars of the popular Euphorbiaceae indoor plants. In this investigation, 22 commercial cultivars of Euphorbiaceae indoor plants we...
Lamb’s quarters goosefoot (with scientific name “Chenopodium album L.”) can absorb and purify heavy metals from environment. Cesium is one of pollutant and basic elements. Due to similarity to potassium, it can be absorbed by plants intensively. According to its absorption from the environment, cesium effect on anatomical and ontogenical structure of plant was studied. For this purpose, plant s...
The increasing spread of antibiotic-resistant pathogens has raised the interest in alternative antimicrobial treatments. In our study, the functionally active gram-negative bacterium bacteriophage CP933 endolysin was produced in Nicotiana benthamiana plants by a combination of transient expression and vacuole targeting strategies, and its antimicrobial activity was investigated. Expression of t...
Phytoremediation is an emerging technology that employs the use of higher plants for the cleanup of contaminated environments. Fundamental and applied research have unequivocally demonstrated that selected plant species possess the genetic potential to remove, degrade, metabolize, or immobilize a wide range of contaminants. Despite this tremendous potential, phytoremediation is yet to become a ...
The poisoning information database (PIDB) provides clinical toxicological information on commonly encountered toxic substances in Korea. The aim of this study was to estimate the coverage rate of the PIDB by comparing the database with the distribution of toxic substances that real poisoning patients presented to 20 emergency departments. Development of the PIDB started in 2007, and the number ...
Human activities have continuously increased the level of heavy metal ions circulating in the environment. It is important to understand the tolerance of plant species to high concentrations of heavy metals. Very little is known on the response of Eucalyptus species to Zn and Cu toxic concentrations Eucalyptus camaldulensis, E. microtheca, and E. occidentalis seeds were grown in silt and irriga...
Influence of Cadmium Toxicity on Rice Genotypes as Affected by Zinc, Sulfur and Nitrogen Fertilizers
Cadmium (Cd) is among the most widespread and toxic heavy metal in several part of the world. Its toxicity in soil is becoming a severe threat to living organism worldwide. It is one of the main pollutants in paddy fields near industrial areas and highly toxic to plant growth and development of the plants. Cd can be easily taken up by plants and enter the food chain. Therefore, precautionary me...
