Here, we investigated the role of ethylene in high nitrate-induced change in root development in Arabidopsis thaliana using wild types and mutants defective in ethylene signaling (etr1, ein2) and nitr...
Background and Aims Root growth and development are closely dependent upon nitrate supply in the growth medium. To unravel the mechanism underlying dependence of root growth on nitrate, an examination...
Dietary nitrate supplementation positively affects cardiovascular function at rest and energy metabolism during exercise in humans and has recently also been reported to markedly enhance the in vitro ...
Encapsulation is a method used to protect material from certain undesirable environments, for controlled release at a more favorable time and place. Animal productivity would be enhanced if feed addit...
The objectives were to compare the ability of various rumen microbial fractions to reduce nitrate and to assess the effect of nitrate on in vitro fermentation characteristics. Physical and chemical me...
An in vitro study was conducted to determine the effect of nitrate-nitrogen used as a sole dietary nitrogen source on ruminal fermentation characteristics and microbial nitrogen (MN) synthesis. Three ...
The present study examined the effects of nitrate on the tadpoles of 2 ranid frogs (Nyctibatrachus major and Fejervarya limnocharis) studied under laboratory conditions. Tadpoles of these species were...
The influence of foliar GA3 application (0, 10-4, 10-5, or 10-6 M) on the responses of Nigella sativa L. to various levels of N fertilisation (0, 176, 264, 352, or 442 mg N pot-1) was analysed through...
Chinese fir (Cunninghamia lanceolata) has replant problem under field conditions and has been attributed to phenolic allelochemicals, which cause its autotoxicity. To determine the mechanism of inhibi...
The objective of the present study was to determine whether 1-4 galacto-oligosaccharides (GOS) and Candida kefyr combined with nitrate as manipulators could suppress rumen methanogenesis without nitra...
Experiments with pea (Pisum sativum L.) cv. Marat) in a phytotron chamber showed that the process of nitrate assimilation in pea organs depends on temperature in the zone of the roots and on the phase...
Nitrate reductase activity (NRA) was investigated in diferent parts of some Verbascum L. species ( Scrophulariaceae) collected from different altıtudes of Uludag Mountain, Bursa Turkey. NR activi...
