The study of eukaryotic tRNA processing has given rise to an explosion of new information
and insights in the last several years. We now have unprecedented knowledge of each step …

tRNA biology has come of age, revealing an unprecedented level of understanding and
many unexpected discoveries along the way. This review highlights new findings on the …

Compartmentation of the eukaryotic cell requires a complex set of subcellular messages,
including multiple retrograde signals from the chloroplast and mitochondria to the nucleus …

Sulfur amino acid biosynthesis in Saccharomyces cerevisiae involves a large number of
enzymes required for the de novo biosynthesis of methionine and cysteine and the recycling …

Cells respond to salt stress by osmolyte synthesis and by increase of K+ uptake and Na+
efflux at the plasma membrane and of Na+ accumulation at the vacuole. This cellular level of …

Plants are generally well adapted to a wide range of environmental conditions. Even though
they have notably prospered in our planet, stressful conditions such as salinity, drought and …

The halobacteria are the only organisms that are tolerant of salinity at the molecular level. All
other bacteria, all fungi, all plants, and all animals avoid the need for salt tolerance for most …

The maintenance of appropriate intracellular concentrations of alkali metal cations,
principally K+ and Na+, is of utmost importance for living cells, since they determine cell …

Adaptation to changes in extracellular salinity is a critical event for cell survival. Genome-
wide DNA chip analysis has been used to analyze the transcriptional response of yeast cells …

Industrialized world is exposing living organisms to different chemicals and metals such as
lithium (Li). Due to their use in common household items to industrial applications, it is …
