Suspension cultures of Acer pseudoplatanus L. cells grown for 15 days in medium (T. Murashige and F. Skoog. 1962. Physiol. Plant. 15: 473-497) contained 3% sucrose, 1 mg/l 6-benzylaminopurine (BA), and 0.1 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D), referred to here as normal media, removed newly added myo-inositol-2-(3)H up to 100 mg/l in 24 hours and utilized up to 20% of this cyclitol for pectin biosynthesis. When the BA content of the growth medium was raised 10-fold, uptake of myo-inositol was drastically reduced and very little was available for pectin biosynthesis. Neither cell growth as measured by packed cell volume or by dry weight, nor monomer composition of pectic polysaccharides was affected by the increased level of cytokinin. Increasing, 2,4-d 10-fold instead of BA had little or no effect on myo-inositol uptake, although it did reduce the amount of myo-inositol utilized for pectin biosynthesis. Cells grown 15 days in normal media failed to remove added myo-inositol if 3% d-glucose was included. The net result was similar to that found in cells grown in the high BA condition. If a trace amount of d-galactose-1-(14)C was supplied to cells after 15 days of growth in normal, high BA, or high 2,4-d media, there was n...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
