In this research the effect of ethinyl estradiol on somatic embryogenesis of Medicago sativa was investigated. Seeds were grown in vitro on MS medium containing 2,4-D, Kin and NAA for callus induction. Plant regeneration media with 14 different combinations of auxin, cytokinin and ethinyl estradiol were provided. Three to four-week old celli and stem or hypocotyl segments of Medicago sativa wer...
Eddy covariance and static chambers are different-scale methods for monitoring agricultural N2O that, when used together on heterogeneous agricultural landscapes, can help identify flux sources and sinks and evaluate the effect of management interventions on landscape-scale N2O emissions. This study compared the N2O flux data obtained by eddy covariance and static chambers during a short-term N...
This study investigated the vitamin contents and health benefits of nine wild plants consumed as food, medicine, or animal feed in around Elazığ Malatya, Turkey. The introduced Rheum ribes, Gundelia tournefortii, Tragopogon reticulatus, Urtica dioica, Asphodelus aestivus, Medicago sativa, Nasturtium officinale, Mentha pulegium, Capsella pastoris. results showed that were common ingredients Turk...
The mutagenic effects of low-energy ions have been identified by genetic studies for decades. Due to the short penetration distance of ions, however, the underlying mechanism(s) is still not quite clarified. Recently, increasing data have been accumulated concerning the existence and manifestation of radiation induced bystander/abscopal effects in vivo in the whole-organism environment. In this...

An adenylate cyclase activity in Medicago sativa L. (alfalfa) roots was partially characterized. The enzyme activity remains in the supernatant fluid after centrifugation at 105,000 g and shows in crude extracts an apparent Mr of about 84,000. The enzyme is active with Mg2+ and Ca2+ as bivalent cations, and is inhibited by EGTA and by chlorpromazine. Calmodulin from bovine brain or spinach leav...
The composition of phosphorus-containing compounds of intact lyophilized alfalfa tissue has been determined, in part, by solid-state (31)P nuclear magnetic resonance. The tissue (Medicago sativa L., cv Regen S; and some of its crosses) was grown in culture under both nonregenerating and regenerating conditions, the latter enhanced by the addition of specific amino acids. Analysis of the (31)P n...
The nodule cysteine-rich (NCR) groups of defensin-like (DEFL) genes are one of the largest gene families expressed in the nodules of some legume plants. They have only been observed in the inverted repeat loss clade (IRLC) of legumes, which includes the model legume Medicago truncatula. NCRs are reported to play an important role in plant-microbe interactions. To understand their diversity we a...
