Gamma-Aminobutyric acid (GABA) accumulates in plants following exposure to heavy metals. To investigate the role of GABA in cadmium (Cd) tolerance and elucidate the underlying mechanisms, GABA (0, 25 and 50 µM) was applied to Cd-treated maize plants. Vegetative growth parameters were improved in
Water shortage limits plant growth and development by inducing physiological and metabolic disorders, while arbuscular mycorrhizal (AM) symbiosis can improve plant adaptation to drought stress by altering some metabolic and signaling pathways. In this study, root growth and levels of some
Objective: To investigate the expression of gamma-aminobutyric acid type A receptor beta3 subunit (GABRB3) on cleft palate in C57BL/6J mice induced by 2,3,7,8-tetrachlorodibenzo- p-dioxin (TCDD). Methods: Sixty C57BL/6J pregnant mice on gestation day (GD) 10.5 were divided into two
The current study investigated the γ-aminobutyric acid (GABA) levels and GABA metabolic enzymes (GABA transaminase (GABA(T)) and glutamate decarboxylase (GAD)) activities at 2 and 4 h after treatment, using a high-performance liquid chromatography with ultraviolet detectors and colorimetric assay,
Salt stress induced Gamma-aminobutyric acid (GABA) accumulation in maize plants. The germination of maize seeds was inhibited seriously by NaCl treatment, while exogenous GABA reduced the inhibition of NaCl on the seeds germination. Effects on SOD, POD and CAT activity of GABA were detected. 1-2
The importance of magnesium (Mg) for plant growth is well-documented. Silicon (Si)-mediated alleviation of mineral deficiencies has been also reported in a number of plant species; however, there is no report on the relevance of Si nutrition in plants grown in Mg-deficient condition. Therefore, in
Currently, imidacloprid (IMI) is the first insecticide and the second agrochemical highly applied all over the world. Here, we report on the impacts of IMI on neurobehavioral performance, oxidative stress, and apoptotic changes in the brain in either adult or adolescent rats. Forty male rats (adult
We studied the influence of metabolites of gamma-aminobutyric shunt of the tricarboxylic acid cycle on the activities of aconitate hydratase (EC.4.2.1.3) as well as NAD- and NADP-specific isocitrate dehydrogenases (EC.1.1.1.41 and EC.1.1.1.42, respectively) using purified enzyme preparations from
Arbuscular mycorrhizal fungi as an important soil microbe have been demonstrated to mitigate the harmful effects of stress on plants. However, little is known about the molecular mechanisms underlying the AM symbiotic response to low temperature. Here, differentially expressed genes (DEGs) in the
BACKGROUND
In contrast to animals and lower plants such as mosses and ferns, sperm cells of flowering plants (angiosperms) are immobile and require transportation to the female gametes via the vegetative pollen tube cell to achieve double fertilization. The path of the pollen tube towards the female
The neurotoxic insecticide chlordecone was administered orally to "young" (4-6 wk old) and "old" (6 mo old) mice in a dose of 25 mg/kg X d in 10 ml/kg corn oil. Age-matched control mice received 10 ml/kg X d corn oil. The acute (24 h after a single dose) and subchronic (24 h after 8 daily doses)
One hundred and fifty-six strains isolated from corn (Zea mays L.), forage paddy rice (Oryza sativa L.), sorghum (Sorghum bicolor L.) and alfalfa (Medicago sativa L.) silages prepared on dairy farms were screened, of which 110 isolates were considered to be lactic acid bacteria (LAB) according to
