TL;DR: Direct evidence is reported that enzymes of starch metabolism (amylopectin synthesis) are regulated by protein phosphorylation and indicate a wider role for protein phosphORYlation and protein–protein interactions in the control of starch anabolism and catabolism.

TL;DR: The focus will be directed toward various aspects of water deprivation and salinity response efficiency in Poaceae, given the importance of the plant cell wall in sensing environmental constraints and in mediating a response to abiotic stress.

TL;DR: In barley, western blots confirmed that P2-G6PDH protein was induced in the roots by nitrogen, and the changes measured in cytosolic G 6PDH seem correlated to more general cell growth processes, and do not appear to be directly involved in glutamate synthesis.

TL;DR: Investigation of the expression, occurrence and activity of glucose 6 phosphate dehydrogenase, the key-enzyme of the Oxidative Pentose Phosphate Pathway, in tomato plants exposed to short- and long-term drought stress shows significant increase in total activity, and results clearly suggest that abscissic acid (ABA) pathway and signaling cascade (protein phosphatase 2C PP2C) could be strictly related to increased G6PDH expression and activities.

TL;DR: It is concluded that growth of cryophilic algae at low temperature is favoured by elevated photosynthesis and respiration rates, but that it could be limited by a high respiration : photosynthesis ratio.
