Abiotic stress tolerance of plants is a very complex trait and involves multiple physiological and biochemical processes. Thus, the improvement of plant stress tolerance should involve pyramiding of multiple genes. In the present study, we report the construction and application

Catalytic RNA molecules (ribozymes) have often been used for the testing of interactions of antibiotics with ribonucleic acids. We showed that the impact of capreomycin and hygromycin B on delta ribozyme catalysis might change dramatically, from stimulation to inhibition, depending

Somatic hypermutation (SHM) requires not only the expression of activation-induced cytidine deaminase, but also transcription in the target regions. However, how transcription guides activation-induced cytidine deaminase in targeting SHM to the Ig genes is not fully understood. Here, we found

Using a yeast two-hybrid screen, we isolated a gene from Schizosaccharomyces pombe, whose product interacts with Mpg1, a GDP-mannose-1-phosphate guanylyltransferase involved in the maintenance of cell wall integrity and glycosylation. We have designated this gene mpg2 based on its similarity

Aminoglycoside antibiotics were among the first antibiotics discovered and used clinically. Although they have never completely fallen out of favor, their importance has waned due to the emergence of other broad-spectrum antibiotics with fewer side effects. Today, with the dramatically
The evolution of low mutation rates in experimental mutator populations of Saccharomyces cerevisiae.

Current biology : CB, 22(13), 1235-1240 (2012-06-26)
Mutation is the source of both beneficial adaptive variation and deleterious genetic load, fueling the opposing selective forces than shape mutation rate evolution. This dichotomy is well illustrated by the evolution of the mutator phenotype, a genome-wide 10- to 100-fold

Concise and efficient syntheses of the aminocyclitol cores of hygromycin A (HMA) and methoxyhygromycin (MHM) have been achieved starting from readily available myo-inositol. Reductive cleavage of myo-inositol orthoformate to the corresponding 1,3-acetal, stereospecific introduction of the amino group via the

The genus Mycobacterium (M.) comprises highly pathogenic bacteria such as M. tuberculosis as well as environmental opportunistic bacteria called non-tuberculous mycobacteria (NTM). While the incidence of tuberculosis is declining in the developed world, infection rates by NTM are increasing. NTM

Long-term plasticity can differ from short-term in recruiting the growth of new synaptic connections, a process that requires the participation of both the presynaptic and postsynaptic components of the synapse. How does information about synaptic plasticity spread from its site

Linear ubiquitination is a novel type of ubiquitination that plays important physiological roles in signalling pathways such as tumour necrosis factor (TNF) signalling. However, little is known about the regulatory mechanisms of linear ubiquitination, except the well-described enzymatic regulators E3

Whereas short-term (minutes) facilitation at Aplysia sensory-motor neuron synapses is presynaptic, long-term (days) facilitation involves synaptic growth, which requires both presynaptic and postsynaptic mechanisms. How are the postsynaptic mechanisms recruited, and when does that process begin? We have been investigating
