Birth and death evolution of polyphenol oxidase (PPO) gene family in Oryza species
Abstract Background Polyphenol oxidases (PPOs) are copper-containing enzymes that catalyze the oxidation of phenolic substrates to quinones. In cereal crops, PPOs contribute to both grain browning and defense responses. During domestication, multiple independent PPO mutations have been selected…

Both semi-dwarf and photoperiod-insensitive traits in rice were important for the Green Revolution
Abstract Background The semi-dwarf high-yielding rice (Oryza sativa) variety IR8 was the major modern line that gave rise to the “Green Revolution” in Asia approximately 60 years ago. Although the sd1 mutation in IR8 responsible for semi-dwarfism is well known, the sequence variation, evolutionary…

Colonization of three Sphagneticola species by Funneliformis mosseae under cadmium stress is beneficial to phosphatase activity and nutrient uptake in rhizosphere soil
Abstract Background Soil cadmium (Cd) contamination poses threats to ecosystems and human health, and the plant arbuscular mycorrhizal fungi (AMF) symbiotic system represents a promising green remediation strategy. However, the underlying mechanisms are complex and context-dependent, and systematic…

Colourful agrobiodiversity: morphology and phenology of bean landraces to face commodification of the commons in the southern Andes
Abstract In recent decades, agrobiodiversity has significantly declined due to genetic erosion. Conservation strategies in response include both ‘in situ’ and ‘ex situ’ methods, with a third approach called ‘in vivo’ conservation, standing out as a promising approach for conserving agrobiodiversity…

Identification of hotspots of crop wild relatives in Germany to promote their in situ conservation in a network of genetic reserves
Abstract Background Crop wild relatives (CWR) represent a valuable resource for ensuring food security. Although they are negatively affected by the loss of habitats due to climate change and land use change, they are underrepresented in conservation programmes. The establishment of genetic reserve…

From biophysical interaction to structural modeling: bi-terminal G and TGS domains drive rice OsYchF1-OsGAP1 complex formation
Abstract OsYchF1 belongs to the YchF subfamily in the Obg family of G proteins, and comprises a core G domain, an α-helical domain, and a TGS domain from the N-terminus to the C-terminus. The C2-domain Oryza sativa GTPase-activating protein (OsGAP1) binds to and accelerates the enzyme activity of…
