Regulatory mechanisms involved in cold acclimation response: a review

REVIEW : Post - translational regulation of cold acclimation response

A Review of the Mechanisms Involved in the Immunopathogenesis of SARS-CoV-2

Coronaviruses belong to the Coronaviridae family and three SARS-CoV, MERS-CoV and SARS-CoV-2 pathogens are found in this family, all of which cause respiratory disorders in human beings. SARS-CoV-2 is a RNA virus of approximately 80-160 nm in size and genomic size of approximately 27-35 kb which causes COVID-19. Symptoms of COVID-19 include fever, dry cough, fatigue and muscle weakness, shortne...

Are pectins involved in cold acclimation and de-acclimation of winter oil-seed rape plants?

BACKGROUND AND AIMS The hypothesis was tested that pectin content and methylation degree participate in regulation of cell wall mechanical properties and in this way may affect tissue growth and freezing resistance over the course of plant cold acclimation and de-acclimation. METHODS Experiments were carried on the leaves of two double-haploid lines of winter oil-seed rape (Brassica napus sub...

Major regulatory mechanisms involved in sperm motility

The genetic bases and molecular mechanisms involved in the assembly and function of the flagellum components as well as in the regulation of the flagellar movement are not fully understood, especially in humans. There are several causes for sperm immotility, of which some can be avoided and corrected, whereas other are related to genetic defects and deserve full investigation to give a diagnosi...

Putrescine is involved in Arabidopsis freezing tolerance and cold acclimation by regulating abscisic acid levels in response to low temperature.

The levels of endogenous polyamines have been shown to increase in plant cells challenged with low temperature; however, the functions of polyamines in the regulation of cold stress responses are unknown. Here, we show that the accumulation of putrescine under cold stress is essential for proper cold acclimation and survival at freezing temperatures because Arabidopsis (Arabidopsis thaliana) mu...
