The genus Oryza is of utmost importance to human civilization as two of its species became agronomically productive and widely cultivated, and also because wild rice is a treasure trove of beneficial alleles that can be used for crop improvement. Most of the wild rice genotypes are known for their stress tolerance several times more than the domesticated rice varieties. In this study, we aimed to carry out an exhaustive genomic survey to identify glyoxalase I (GLYI) and glyoxalase II (GLYII) genes across the 11 rice genomes sequenced so far.

Non-structural protein 1 (Nsp1) is a key component of the infectious process caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2), responsible for the COVID-19 pandemic. Our previous data demonstrated that Nsp1 can degrade both RNA and DNA in the absence of the ribosome, a process dependent on the metal ions Mn, Ca, or Mg (Salgueiro et al., SARS-CoV2 Nsp1 is a metal-dependent DNA and RNA endonuclease.

Fructose occurs in foods and as a metabolite in vivo. It can be degraded, leading to the formation of reactive carbonyl compounds, which may influence food properties and have an impact on health. The present study performed an in-depth qualitative and quantitative profiling of fructose degradation products.
