Abstract

The present work was carried out to evaluate how plant growth and cultural practices influence the amount and composition of cuticular waxes on leaves of rose cultivars. The total amount of cuticular wax per leaf area was higher for rose cultivar Apollo Parade than for Charming Parade. Both cultivars had waxes dominated by alkanes, with the major alkanes being the C31 and C33 homologues. Primary alcohols were the next most abundant constituent class, with C26 as the dominant homologue. Compared with Charming Parade, Apollo Parade had higher proportions of its total wax load as primary alcohols but lower acids and aldehydes. The proportion of alkanes in the total load on these cultivars was similar. Commercially produced roses are routinely treated with paclobutrazol (PBZ) to retard growth. PBZ treatments caused a 10% increase in total wax load and changes in the proportions of certain wax constituents within 11 days of application. Notable was an increase in the total proportion of acids in the total load 25 days after PBZ application, primarily because of increased C28 acids. An alternative method of retarding plant growth is production of roses under limited water availability. When Apollo Parade roses experienced periods of ...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.
