In Clostridium thermocellum, a thermophilic anaerobic bacterium able to rapidly ferment cellulose to ethanol, pyruvate kinase (EC 2.7.1.40) is absent based on both the genome sequence and enzymatic assays. Instead, a new pathway converting phosphoenolpyruvate to pyruvate via a three-step pathway involving phosphoenolpyruvate carboxykinase, NADH-linked malate dehydrogenase, and NADP-dependent ma...

To find the protective role of exogenous nitric oxide (NO) on salinity-stressed rice seedlings, a CRD-based factorial experiment with three replications was conducted in Agronomy Laboratory of the Faculty of Agricultural Sciences, University of Guilan, in 2012. The experimental design consisted of healthy and vigorous seedlings of two rice cultivars, Khazar and Goohar, the last already known as...

1. A specific method is described for the measurement of angiotensin I converting enzyme activity in plasma with 125 I-labelled angiotensin I used as substrate. 2. Converting enzyme activity in plasma from fifteen normal subjects, eleven patients with sarcoidosis, twelve patients with chronic obstructive pulmonary disease and three patients with shock lung was assayed by this technique. 3. Pati...

When drought occurs during the maize-filling period, probability of yield decline increases. Abscisic acid (ABA) plays a regulatory role in physiological and metabolic activities plant development. However, its effect on antioxidant system maize leaves grain-filling stage is unclear. Maize plants (Zhengdan958) were used as an experimental material, ABA was sprayed stage. The placed under condit...

In lysosomal diseases, enzyme deficiency is caused by misfolding of mutant protein with abnormal steric structure that expressed gene mutation. Chaperone therapy a new molecular therapeutic approach primarily for diseases. The misfolded digested rapidly or aggregated to induce endoplasmic reticulum stress. As result, the catalytic activity lost. following sequence events results in chaperone ac...

Serotonin is a well-known agent that plays various roles in animals, and little known plants. In this study, the effect of exogenous serotonin was tested on Brassica napus L. (rapeseed) under salt stress. The results revealed application 200 µmol/L had best protection salinity. Exogenous effectively alleviated growth inhibition seedlings caused by salinity, significantly promoted accumulation f...

High electrical conductivity (EC) in cultivation systems with the recirculating nutrient solutions can affect plant growth and development. This study aimed to investigate effect of salicylic acid (SA) on selected physiological biochemical parameters sweet pepper (Capsicum annum L.) growing aeroponically at standard high concentrations nutritive solutions. Four experimental variants were tested...

Salt stress, particularly short-term salt stress, is among the most serious abiotic factors limiting plant survival and growth in China. It has been established that exogenous spermidine (Spd) stimulates plant tolerance to salt stress. The present study utilized two zoysiagrass cultivars commonly grown in China that exhibit either sensitive (cv. Z081) or tolerant (cv. Z057) adaptation capacity ...
