Abstract

Among the wild-type ecotypes of Arabidopsis thaliana whose shape of inflorescence is categorized as raceme, the ecotype Landsberg harboring the erecta (er) mutation shows a corymb-like inflorescence, namely, a compact inflorescence with a flattened arrangement of flower buds at the tip. The fact that the ER gene encodes a receptor-like protein kinase implies the presence of a signaling cascade responsible for the inflorescence morphology of flowering plants. We report here the characterization of another mutant with a corymb-like inflorescence, named corymbosa2 (crm2), and the isolation of the CRM2 gene. While the er mutation causes a severe reduction in the length of pedicels, the crm2 mutation results in a significant delay in the initiation of internode elongation and in the development of flowers, despite having little effect on the timing of floral induction. Consequently, the number of flower buds is apparently increased at the tip of crm2 inflorescence. The crm2 er double mutant shows an additive phenotype. These results suggest that CRM2 and ER may act in different ways to generate wild-type inflorescence. The CRM2 gene was isolated by positional cloning and appears to encode a polypeptide with no significant homology t...Continue Reading

COVID-19

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

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.

Microbicide

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.
