catalase/oryza sativa

Different rice (Oryza sativa L.) genotypes were subjected to high salinity and low temperature (150 mM NaCl and 13°C, respectively) for 0, 6, 24, 48, or 72 h. We evaluated the simultaneous expression of the genes OsCATA, OsCATB, and OsCATC, correlated gene expression with enzyme activity, and

Catalase is the major H(2)O(2)-scavenging enzyme in all aerobic organisms. From the cDNA sequences of three rice (Oryza sativa L.) genes that encode for predicted catalases (OsCatA, OsCatB, and OsCatC), complete ORFs were subcloned into pET21a and expressed as (His)(6)-tagged proteins in Escherichia

Stress induces the generation of Reactive Oxygen Species (ROS) that ultimately hampers the growth, development, and productivity of the plant. As an antioxidant enzyme, catalase converts hydrogen peroxide to water and keeps ROS level down to protect cells from stress-induced apoptosis. Here, a

Saliva plays an important role in host plant-phloem-feeding insect molecular interactions. To better elucidate the role of insect saliva, a series of experiments were conducted to establish if catalase from the salivary glands of the brown planthopper (BPH; Nilaparvata lugens Stål) was secreted into

Cadmium (Cd) is absorbed readily by rice plants and is transferred to humans when contaminated rice is consumed. Adding selenium (Se) to the plant nutrient solutions reduces the accumulation of Cd in the rice (Oryza sativa L.) seedlings. However, as the relevant underlying mechanism remains unclear,

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

Rice (Oryza sativa L.), a major staple food for billions of people, was assessed for its phytotoxicity of copper oxide nanoparticle (CuO NPs, size < 50 nm). Under hydroponic condition, seven days of exposure to 62.5, 125, and 250 mg/L CuO NPs significantly suppressed the growth rate of

The rice (Oryza sativa L.) catalase (EC 1.11.1.6) gene CatB is expressed in roots and cultured cells. We examined the promoter activity of its 5'-flanking region in a monocot and in two dicots. Transient expression assays in rice Oc and tobacco BY-2 suspension cell protoplasts showed that CatB's

We isolated and sequenced a genomic clone (CatA) encoding CAT-A catalase, a homologue of the maize catalase isozyme 3 (CAT-3) from rice (Oryza sativa L.). The 5'-upstream non-coding region had very low similarity with the maize Cat3 gene and possible cis elements and sequence motifs in the maize

NaCl and PEG stresses have negative impacts on seed germination and early seedling establishment in Oryza sativa. The present study was designed to ascertain the influence of different priming techniques (Hydro priming-HyP, Halo priming-HP, UV-B priming-UP) in enhancing oxidative and

We have utilized an efficient method to enrich cDNA libraries for novel genes and genes responsive to drought stress in rice (Oryza sativa L. subsp. indica). We separately constructed standard and normalized cDNA libraries from leaf tissue of rice seedlings grown under controlled drought stress.

Tourist elements comprise a group of transposable elements in plants. One of these elements, Tourist-OsaCatA(a Tourist C element), has been found in the 5; flanking region of a catalase gene, CatA, in rice (Oryza sativa). Using reverse transcriptase-PCR (RT-PCR) analyses of leaves, roots, flowers

The GST (glutathione S-transferase) and GST+CAT1 (catalase 1) of Suaeda salsa were introduced into a low temperature-sensitive rice cultivar (Oryza sativa cv. Zhonghua No.11) by Agrobacterium tumefaciens-mediated transformation under the control of cauliflower mosaic virus (CaMV) 35S promoter, and

Silicon (Si) has an important function in reducing the damage of environmental stress on plants. Acid rain is a serious abiotic stress factor, and Si can alleviate the stress induced by acid rain on plants. Based on these assumptions, we investigated the effects of silicon on the growth, root
