Soluble sugar levels affect a diverse array of plant developmental processes. For example, exposure to high levels of glucose or sucrose inhibits early seedling development of Arabidopsis thaliana (L.) Heynh. Media-shift experiments indicate that Arabidopsis seedlings lose their sensitivity to the inhibitory effects of high sugar levels on early development within approximately two days after t...

Haloarcula sp. CBA1115, isolated from non-purified solar salts from South Korea, is a halophilic archaeon belonging to the family Halobacteriaceae. Here, we present the complete genome sequence of the strain Haloarcula sp. CBA1115 (4,225,046bp, with a G+C content of 61.98%), which is distributed over one chromosome and five plasmids. A comparison of the genome sequence of Haloarcula sp. CBA1115...

Seed germination, emergence and crop growth are often constrained by multiple environmental stress under field condition limiting productivity. priming, a age old inexpensive technique, consisting of soaking seeds in priming agent prior to sowing, has been applied different crops conditions with varying degrees success. To understand the significance this potentially transformative agronomic st...

We hypothesized that TRPV4, a member of the transient receptor family of ion channels, functions as a sensory transducer for osmotic stimulus-induced nociception. We found that, as expected for a transducer molecule, TRPV4 protein is transported in sensory nerve distally toward the peripheral nerve endings. In vivo single-fiber recordings in rat showed that hypotonic solution activated 54% of C...

Several bacterial response regulator proteins (CheY, NRI, PhoB, and OmpR) become phosphorylated in vitro when incubated with acetyl phosphate. In the presence of high levels of acetyl phosphate and Mg2+, CheY reached steady state phosphorylation in less than 30 s; NRI and PhoB reached steady state more slowly (t1/2 to steady state of 1.5 and > 15 min, respectively). A simple method was develope...

Because of the increased concern over use of human body fluids in physiology teaching laboratories, we developed an exercise in renal function that utilizes laboratory rats. The purpose is to demonstrate the role of the kidneys in the homeostatic control of extracellular fluid volume, plasma ionic concentrations, and osmolarity. Three treatment groups are utilized: a volume-expanded (access to ...

In this paper we critically review anatomic, electrophysiological, physiological, and behavioral evidence for neural receptors in the liver. Several lines of evidence suggest that the afferent innervation of the liver may be substantial, although few anatomic studies have directly addressed the question of an hepatic sensory supply. On the other hand, there is convincing functional evidence for...
