Abstract

Arabinogalactan proteins (AGPs) are abundant complex macromolecules involved in both reproductive and vegetative plant growth. They are secreted at pollen tube tips in Lilium longiflorum. Here, we report the effect of the (beta-D-glucosyl)3 Yariv phenylglycoside, known to interact with AGPs, on pollen tube extension in several plant species. In Annona cherimola the Yariv reagent clearly inhibited pollen tube extension within 1-2 h of treatment, as demonstrated previously for L. longiflorum, but had no effect on Lycopersicon pimpinellifolium, Aquilegia eximia, and Nicotiana tabacum. With the monoclonal antibody JIM13 we also examined these same species for evidence that they secreted AGPs at their pollen tube tips. Only A. cherimola showed evidence of AGPs at the pollen tube tip as does lily. The Yariv reagent causes arrest of tube growth in both A. cherimola and lily, but its removal from the medium allows regeneration of new tip growth in both species. We show that the site of the new emerging tip in lily can be predicted by localization of AGP secretion. Labeling with JIM13 appeared on the flanks of the arrested tip 1 h after removal of the Yariv reagent from the growth medium. After 4 h, many of the Yariv reagent-treated pol...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.
