Our long-range objectives are to understand and, as feasible, predict the distribution and abundance of pelagic organisms, particularly in regard to their physical environment and its changes. The objective of the proposed research is to identify the mechanism that controls onset of dormancy in open-ocean copepods and thus explain spatial and temporal variation in dormancy response. Specificall...

• Seed dormancy controls germination and plays a crucial role in the life cycle of plants. Chromatin modifications are involved in the regulation of seed dormancy; however, little is known about the underlying mechanism. • KYP/SUVH4 is required for histone H3 lysine 9 dimethylation. Mutations in this gene cause increased seed dormancy. KYP/SUVH4-overexpressing Arabidopsis plants show decreased ...

The development of seed dormancy is an aspect of seed maturation, the last stage of seed development. To isolate mutants of Arabidopsis thaliana that are affected in this process, we selected directly for the absence of dormancy among freshly harvested M2 seeds. The screen yielded two mutants exhibiting a reduced dormancy, rdo1 and rdo2, that are specifically affected in dormancy determined by ...

Seed germination under the appropriate environmental conditions is important both for plant species survival and for successful agriculture. Seed dormancy, which controls germination time, is one of the adaptation mechanisms and domestication traits [1]. Seed dormancy is generally defined as the absence of germination of a viable seed under conditions that are favorable for germination [2]. The...

A 33-year-old patient with hypokalaemia associated with severe myopathy following liquorice ingestion is described. Potassium depletion was confirmed by total body potassium measurements and myopathy was established by electromyography and enzyme studies. The potential hazard of chronic liquorice consumption even as a sweet is illustrated by this case.

The number of patients with Alzheimer’s disease (AD), and/or behavioral and psychological symptoms of dementia (BPSD) has been markedly increasing all over the world, and has become a social and health problem. Furthermore, it has been recently established that the diabetic condition is a major risk factor for the development of dementia. Second-generation antipsychotics have been used, but som...

The flavor volatile compounds of dried red cashew flowers, cashew leaf-buds, cashew leaves and licorice roots as well as flavored herb teas were analyzed by gas chromatography-mass spectrophotometry (GC-MS). It was found that terpenes, including α-pinene, α-phellandrene and β-phellandrene were the main volatiles in the cashew leaf-buds and leaves. The major volatile compounds of the red cashew ...

Numerous viruses cause latent infections in humans, and reactivation often results in pain and suffering. While vaccines for several of these viruses are available or currently being studied in clinical trials, and antiviral therapies have been successful in preventing or treating active infection, therapy to eradicate latent infection has lagged behind. A new study reported in this issue of th...

Reproductive meristems and embryos display dormancy mechanisms in specialized structures named respectively buds and seeds that arrest the growth of perennial plants until environmental conditions are optimal for survival. Dormancy shows common physiological features in buds and seeds. A genotype-specific period of chilling is usually required to release dormancy by molecular mechanisms that ar...
