The biochemistry of nitrogen mobilization: purine ring catabolism.
TLDR
The enzymatic route of purine ring catabolism has recently been completed by the discovery of several novel enzymes identified through comparative genome analyses as discussed by the authors, which has also emerged that catabolic intermediates, the ureides allantoin and allantoate, are likely to be involved in protecting plants against abiotic stress.About:

In Posidonia oceanica cadmium induces changes in DNA methylation and chromatin patterning
TL;DR: The data demonstrate that Cd perturbs the DNA methylation status through the involvement of a specific methyltransferase, linked to nuclear chromatin reconfiguration likely to establish a new balance of expressed/repressed chromatin.

Do plants need nitrate? The mechanisms by which nitrogen form affects plants
TL;DR: It is concluded that the form of N available to plants can affect their time and rate of seed germination, leaf expansion and function, dry matter partitioning between shoot and root, and root architecture.

Boosting Crop Yields with Plant Steroids
TL;DR: The potential and strategies for enhancing yield in crops by genetically altering sterol and BR metabolism and signaling or by exogenously applying BRs and known inhibitors of their pathways are discussed.

Plant Survival in a Changing Environment: The Role of Nitric Oxide in Plant Responses to Abiotic Stress
TL;DR: This review focuses on the current knowledge of the role of nitric oxide in adaptive plant responses to some specific abiotic stress conditions, particularly low mineral nutrient supply, drought, salinity and high UV-B radiation.

Transporters involved in source to sink partitioning of amino acids and ureides: opportunities for crop improvement
TL;DR: The partitioning of amino acids and ureides within the plant is described, and their importance for source and sink physiology discussed, and possibilities for genetic manipulation of organic nitrogen transporter activities to confer increases in crop productivity are explored.

High-Affinity Manganese Uptake by the Metal Transporter NRAMP1 Is Essential for Arabidopsis Growth in Low Manganese Conditions
TL;DR: It is demonstrated that NRAMP1 is a physiological manganese transporter in Arabidopsis and restores the capacity of the iron-regulated transporter1 mutant to take up iron and cobalt, indicating thatNRAMP1 has a broad selectivity in vivo.
