Alternative Splicing Plays a Major Role in Plant Response to Cold Temperatures

/in , /by

Plants in temperate regions experience near-freezing temperatures that allow them to develop a cold response prior to freezing. This cold acclimation process involves changes to chromatin structure, transcription, RNA processing, translation, post-translational modifications and protein stability. Genome-wide studies of cold acclimation have largely focused on changes to transcription. Several pathways are known to undergo changes […]

Autophagy: Both Friend and Foe in Pseudomonas Infection

/in , , /by

Eukaryotes use two major systems for getting rid of unwanted proteins: the ubiquitin proteasome system and autophagy. The proteasome degrades ubiquitinated proteins. Autophagosomal vesicles encapsulate cellular waste and either deliver it to the vacuole or fuse with a lysosome. Animal cells use autophagy for pathogen defense; however, some pathogens have evolved to exploit autophagy to […]
