Metabolism of Purine Alkaloids and Xanthine in Leaves of Maté ()
Natural Product Communications, 2015 Accumulation and metabolism of purine alkaloids in leaves of maté ( Ilex paraguariensis ) were investigated. In winter, leaves accumulated caffeine but not theobromine, indicating that caffeine is the end product of purine alkaloid synthesis in maté.

Journal of Agronomy and Crop Science, Volume 211, Issue 1, January 2025.ABSTRACT Legumes are among the most utilised agronomic plant species due to their symbiotic association with N2‐fixing bacteria. Since N2 fixation entails high ATP cost, salt stress disrupts N2 fixation in the symbiont, but increases the production of osmolytes and antioxidant systems in the host plant.

Soybean genomics research community strategic plan: A vision for 2024–2028
The Plant Genome, Volume 17, Issue 4, December 2024.Abstract This strategic plan summarizes the major accomplishments achieved in the last quinquennial by the soybean [Glycine max (L.) Merr.] genetics and genomics research community and outlines key priorities for the next 5 years (2024–2028). This work is the result of deliberations among over 50 soybean researchers during a 2‐day workshop in St Louis,

Plant, Cell &Environment, Volume 47, Issue 12, Page 5511-5526, December 2024.Abstract Nitrogen (N) nutrition impacts on primary carbon metabolism and can lead to changes in δ13C of respired CO2. However, uncertainty remains as to whether (1) the effect of N nutrition is observed in all species, (2) N source also impacts on respired CO2 in roots and (3) a metabolic model can be constructed to predict δ13C of respired CO2 under ...
