Role of the Plasma Membrane in Freezing Injury and Cold Acclimation
TL;DR: An attempt is made to explore the nature of freezing injury of plants on which to formulate a mechanism(s) of injury and how the biochemical changes occurring during cold acclimation can be accurately assessed.

Changes in leaf ultrastructure and carbohydrates in Arabidopsis thaliana L. (Heyn) cv. Columbia during rapid cold acclimation
Z. Ristic,E. N. Ashworth +1 more
TL;DR: It is suggested that cold acclimation in Arabidopsis thaliana induces changes in both plasma membrane properties and carbohydrate composition, and these structures are proposed to be called membraglobuli.

Do plant cells secrete exosomes derived from multivesicular bodies
TL;DR: The recent studies have revealed that MVBs and paramural vesicles proliferate when cell wall appositions are rapidly deposited beneath fungal penetration attempts or during plugging of plasmodesmata between hypersensitive cells and their intact neighboring cells, indicating a potential secretion of exosome-like vesicle into the extracellular space by fusion of MVBs with the plasma membrane.

Cambial ultrastructure and biochemistry: changes in relation to vascular tissue differentiation and the seasonal cycle
TL;DR: Detailed studies of nucleic acid metabolism during the seasonal cycle showed that the nuclei of dormant cells were blocked in the G1 phase as expected from previous results with apical meristems.

Developmental and stress regulation of RCI2A and RCI2B, two cold-inducible genes of arabidopsis encoding highly conserved hydrophobic proteins.
TL;DR: RCI2A and RCI2B are regulated at transcriptional level during plant development and in response to different environmental stimuli and treatments, indicating that they must be regulated by both environmental factors and developmental cues.
