Inhibition of rhizobial cheaters by the host Medicago truncatula involves repression of symbiotic functions and induction of defense

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1458-1474, November 2025.
Summary In symbiotic plant–microbe interactions, the host invests considerable amounts of resources in the microbial partner. If the microbe does not reciprocate with a comparable symbiotic benefit, it is regarded as a cheater. The host responds to cheaters with negative feedback mechanisms (sanctions) to prevent fitness deficits resulting from being ...

Breeding for plant‐based proteins in pulse and legume crops: Perspectives, challenges and opportunities

open access: yesCrop Science, Volume 65, Issue 4, July/August 2025.
Abstract The consumption of plant proteins is increasing worldwide as a viable alternative to animal‐derived proteins in the marketplace. The projected increase in global population to at least 10 billion by 2050 is placing greater pressure on the food supply, particularly due to the rising demand for large‐scale protein production.

Chemical basis of nitrogen recovery through the ureide pathway: formation and hydrolysis of S-ureidoglycine in plants and bacteria

open access: yes, 2010
While some organisms, including humans, eliminate oxidized purines to get rid of excess nitrogen, for many others the recovery of the purine ring nitrogen is vital.

CONSEQUENCES OF PURINE DEGRADATION INHIBITION INDUCED BY ALLOPURINOL ON GROWTH, NITROGENOUS COMPOUNDS AND CARBOHYDRATES IN YAM BEAN (Pachyrhizus erosus Urban) [PDF]

open access: yes, 2017
Allopurinol effects on Xanthine dehydrogenase (XDH) and uricase, the key enzymes of conversion of fixed nitrogen in ureides (allantoin and allantoate), exporting forms of ammonia from nodules to leaves, where investigated on growth, amino-compounds and ...

Gene Context Analysis Reveals Functional Divergence between Hypothetically Equivalent Enzymes of the Purine–Ureide Pathway

open access: yes, 2016
A major problem of genome annotation is the assignment of a function to a large number of genes of known sequences through comparison with a relatively small number of experimentally characterized genes.

Arginine metabolism is a biomarker of red blood cell and human aging

open access: yesAging Cell, Volume 24, Issue 2, February 2025.
Reisz et al. examined age‐related changes in erythrocyte metabolism using 15,700 specimens from 13,757 individuals across four cohorts, including healthy donors and sickle cell disease patients. The study identifies alterations in arginine metabolism associated with chronological age, linking them to erythrocyte function, vesiculation, and post ...

Linking the key physiological functions of essential micronutrients to their deficiency symptoms in plants

open access: yesNew Phytologist, Volume 242, Issue 3, Page 881-902, May 2024.
Summary In this review, we untangle the physiological key functions of the essential micronutrients and link them to the deficiency responses in plants. Knowledge of these responses at the mechanistic level, and the resulting deficiency symptoms, have improved over the last decade and it appears timely to review recent insights for each of them.
