Herbivorous turtle ants obtain essential nutrients from a conserved nitrogen-recycling gut microbiome. [PDF]
, 2018 Nitrogen acquisition is a major challenge for herbivorous animals, and the repeated origins of herbivory across the ants have raised expectations that nutritional symbionts have shaped their diversification.

The Plant Journal, Volume 103, Issue 6, Page 2193-2210, September 2020., 2020 SUMMARY Potato (Solanum tuberosum L.) is one of the world's most important crops, but it is facing major challenges due to climatic changes. To investigate the effects of intermittent drought on the natural variability of plant morphology and tuber metabolism in a novel potato association panel comprising 258 varieties we performed an augmented block ...

Enzymic Degradation of Allantoate in Developing Soybeans [PDF]
Plant Physiology, 1985 A Mn(2+)-dependent enzymic breakdown of allantoate has been detected in crude and partially purified extracts of developing soybeans. The products detected were CO(2), NH(3), glyoxylate, labile glyoxylate derivatives, and low levels of urea. Urea is initially produced at less than 10% the rate of urease-independent CO(2) release indicating that the ...

The Basic Proteins of Bovine Allantoic Fluid [PDF]
Biology of Reproduction, 1987 This paper reports the separation of highly cationic proteins (i.e. pI greater than 9.0) of bovine allantoic fluid and their possible pathogenic properties. Experimentally, polycations and cationic proteins of pI greater than 10 induced intravascular coagulation and hemolysis, as well as precipitation of fibrinogen and proteinuria.

Metagenomics reveals sediment microbial community response to Deepwater Horizon oil spill [PDF]
, 2014 The Deepwater Horizon (DWH) oil spill in the spring of 2010 resulted in an input of ∼4.1 million barrels of oil to the Gulf of Mexico; >22% of this oil is unaccounted for, with unknown environmental consequences.

Characterization of the gene cluster involved in allantoate catabolism and its transcriptional regulation by the RpiR-type repressor HpxU in Klebsiella pneumoniae [PDF]
, 2013 Bacteria, fungi, and plants have metabolic pathways for the utilization of nitrogen present in purine bases. In Klebsiella pneumoniae, the genes responsible for the assimilation of purine ring nitrogen are distributed in three separated clusters.
