Exposure of Arabidopsis to low temperatures results in cold acclimation where freezing tolerance is enhanced. To achieve a wider view of the role of transcriptome to biochemical changes that occur during cold acclimation, analyses of concurrent transcript and metabolite changes during cold acclimation was performed revealing the dynamics of selected(More)
Leaf senescence is a programmed developmental process governed by various endogenous and exogenous factors, such as the plant developmental stage, leaf age, phytohormone levels, darkness, and exposure to stresses. It was found that, in addition to its well-documented role in the enhancement of plant frost tolerance, overexpression of the(More)
Multiuser MIMO (MU-MIMO) is a new technology adopted in IEEE 802.11ac for enhancing downlink throughput. 802.11ac has an explicit feedback mechanism that enables very high quality channel feedback to be provided to the transmitter, but the overhead can be quite substantial. We propose a differential feedback method that significantly reduces this overhead(More)
Ethylene is commercially used for artificial degreening of early season grapefruits. The present study investigated the effect of degreening and storage period on Star Ruby grapefruit (Citrus paradisi Macf.) bioactive compounds. Freshly harvested grapefruits were degreened in commercial packing shed for 60h using 2ppm of ethylene at a constant temperature(More)
BACKGROUND The etiology of inflammatory bowel disease is believed to involve a shift in the microbiota toward more proinflammatory species. Crohn's disease (CD) usually manifests as one of three phenotypes, involving inflammation of the terminal ileum, the colon, or both. However, what determines the particular phenotype and the level of disease activity(More)
CBF1-3 (C-repeat binding factors) are transcriptional activators governing plant responses to low temperatures. Overexpression of CBF1-3 genes enhances plant frost tolerance, but also causes various pleiotropic effects regarding plant growth and development, mainly growth retardation, and delay of flowering and senescence. In a recent study, we reported(More)
A new natural derivative of the sulfated guanidinium zwitterionic toxin cylindrospermopsin, 7-epi-cylindrospermopsin, was recently isolated from the cyanobacterium Aphanizomenon ovalisporum (Forti). The toxicity of the molecule (LD50 ip 5 d), estimated by mouse bioassay, was 200 microg/kg mouse, a value similar to that of cylindrospermopsin. Treatment of(More)
In the early 1990s, infestations of midge larvae (Chironomidae, Chironomus sp.) were discovered in the potable water system of Tel Aviv, Israel. Control measures, such as draining and cleaning tanks, spraying water into the tank's air space, and electrocution traps of midge adults, were either inadequate or ineffective. In this system, monochloramine(More)
A pre-storage conditioning (CD) treatment of 16 degrees C for 7 d enhanced chilling tolerance of grapefruit and reduced the development of chilling injuries during storage at 5 degrees C. To gain a better understanding of the molecular mechanisms involved in the responses of citrus fruit to low temperatures, we performed genome-wide transcriptional(More)
The latest approach to control of midge larvae in drinking-water supplies is suppression of the planktonic 1st-stage larvae, by using 2 disinfectants, chloramine and copper sulfate. The median lethal concentration for 24-h exposure of the 1st-stage larvae of Chironomus luridus to chloramine and copper sulfate individually was 0.51 and 0.38 mg/liter,(More)
