The effect of rutin and gallic acid on growth, phytochemical and defense gene activation of rice (Oryza sativa L.) was investigated. The seeds of rice were primed with different concentrations of rutin and gallic acid (10-60 µg mL-1) to explicate the effect on germination on water agar plates.

Soil acidification is the main problem in the current rice production. Here, the effects of low pH on the root growth, reactive oxygen species metabolism, plasma membrane functions, and the transcript levels of the related genes were investigated in rice seedlings (Oryza sativa L.) in a hydroponic

OBJECTIVE The purpose of the current study is to investigate the influence of germinated giant embryonic rice consumption on the lipid metabolism and antioxidant system in rats fed a high-cholesterol diet. METHODS Four groups of rats were given a diet containing 1 g cholesterol/kg for 5 weeks. The

Redox homeostasis may be defined as the dynamic equilibrium between electrophiles and nucleophiles to maintain the optimum redox steady state. This mechanism involves complex reactions, including nuclear factor erythroid 2-related factor 2 (Nrf2) pathway, activated by oxidative stress in order to

Nitric oxide cytotoxicity arises from its rapid conversion to peroxynitrite (ONOO(-)) in the presence of superoxide, provoking functional changes in proteins by nitration of tyrosine residues. The physiological significance of this post-translational modification is associated to tissue injury in

Arsenic (As) contamination in rice is at alarming level as majority of rice growing regions are As contaminated such as South East Asia. Restricting the As in aerial parts of rice plant may be an effective strategy to reduce As contamination in food chain. Sulfur (S), an essential element for plant

To estimate the preventive potential of Japanese rice bran (Oryza sativa japonica) against the oxygen radical-related chronic diseases such as cardio-vascular diseases and cancer, antioxidative and antigenotoxic activities of the rice bran extracts were analyzed by using assay systems for lipid

'Violet Nori' is a new spontaneous growing violet rice variety showing a peculiar violet color in its fresh leaves as well. In this paper, the antioxidant properties and the content of total phenols, radical scavengers, and anthocyanins in 'Violet Nori' caryopses, flour, and leaves are explored and

BACKGROUND Brown rice (BR) and germinated brown rice (GBR) are considered as prime sources of carbohydrate and bioactive compounds for more than half of the populations worldwide. Several studies have reported on the proteomics of BR and GBR; however, the proteomic profiles related to the synthesis

An excess of reactive oxygen species (ROS) can cause severe oxidative damage to cellular components in photosynthetic cells. Antioxidant systems, such as the glutathione (GSH) pools, regulate redox status in cells to guard against such damage. Dehydroascorbate reductase (DHAR, EC 1.8.5.1) catalyzes

Ricegrass juice (Oryza sativa L.) was introduced as a functional food as the consumption of sprouts or seedlings has been claimed to provide high nutritive value. Selenium (Se) is a trace mineral that plays a key role in the human antioxidation scheme. Supplementation of Se into plants is one

Whole rice (WR) products with low phytic acid (PA) content and enhanced bio-functional components were obtained by the combination of germination and extrusion processes. Germination conditions (24 h - 35 °C), with a previous soaking process (24 h - 20 °C), were chosen according to the remnant PA

Priming is one of the mechanisms for the induction of the antioxidant defense system and various stress-responsive proteins which help plants to survive under various abiotic stresses. Based on the observation that the rice seedlings primed with UV-B (low dose of UV-B irradiation-6 kJm^-2)
