TLDR
The results showed that the highest concentration of aqueous extracts reduced the mitotic index, the seed germination and the root development of lettuce, and the extracts have also induced chromosome aberrations and cellular death in the roots cells of L. sativa.Abstract:
The lemon grass, Cymbopogon citratus (DC) Stapf, is an important species of Poaceae family commonly used in the folk medicine in many countries. The aim of this study was to investigate the cytotoxic and genotoxic effects of aqueous extracts from C. citratus leaves on Lactuca sativa (lettuce) root tip meristem cells by cytogenetic studies that have never been done before for lemon grass extracts. For this, lettuce seeds were treated for 72h with different concentrations of lemon grass aqueous extracts (5; 10; 20 and 30 mg/mL). The percentage of germination, root development and cellular behavior were analyzed, and the results showed that the highest concentration of aqueous extracts reduced the mitotic index, the seed germination and the root development of lettuce. The extracts have also induced chromosome aberrations and cellular death in the roots cells of L. sativa.read more

TL;DR: The essential oils were found to induce oxidative stress evidenced by the generation of reactive oxygen species, and with the exception of geraniol, induction of apoptosis was confirmed at higher concentrations of the test substances.

TL;DR: Both essential oils and citral caused morphological changes in adult specimens and Mortalities of larval and newly-hatched larvae to adult periods were dose-dependent for the two both oils as for monoterpene citral, reaching 90%.

TL;DR: Understanding the genotoxicity of M. aeruginosa extracts can help determine a possible link between contamination by aquatic cyanobacteria and high risk of primary liver cancer found in some areas as well as establish water level limits for compounds not yet studied.

TL;DR: It is shown that in soybean cells, PCD-activating oxidative stress induced a set of cysteine proteases, and a new role for proteinase inhibitor genes as modulators of PCD in plants is proposed.

Mark L. Gonzalgo,Peter A. Jones +1 more
TL;DR: Two major mechanisms by which DNA methylation may lead to aberrant cell cycle control are investigated: through the generation of transition mutations via deamination-driven events resulting in the inactivation of tumor suppressor genes, or by altering levels of gene expression through epigenetic effects at CpG islands.

TL;DR: The potent inhibitory effects on CYP4502B1 suggest that MYR, and other monoterpenes, interfere with the metabolism of xenobiotics which are substrates for this isoenzyme.
