Along with the co-chaperonin GroES, the chaperonin GroEL plays an essential role in enhancing protein folding or refolding and in protecting proteins against misfolding and aggregation in the cellular environment. The XoGroEL gene (XOO_4288) from Xanthomonas oryzae pv. oryzae was cloned and the protein was expressed, purified and crystallized. The purified XoGroEL protein was crystallized using the hanging-drop vapour-diffusion method and a crystal diffracted to a resolution of 3.4 Å. The crystal belonged to the orthorhombic space group P212121 with 14 monomers in the asymmetric unit, with a corresponding VM of 2.7 Å(3) Da(-1) and a solvent content of 54.5%.

Background: Plant diseases caused by plant pathogens pose a great threat to biodiversity and food security, and the problem of drug resistance caused by traditional antibiotics and fungicides is becoming more and more serious. It is urgent to develop new antibacterial molecules with low toxicity and high efficiency. Marinoquinoline A is an alkaloid isolated from marine actinomycetes and has a variety of pharmacological activities.

Background: Rice is the main food crop for much of the population in China. Therefore, selecting and breeding new disease resistance and drought tolerance in rice is essential to ensure national food security. The utilization of heterosis has significantly enhanced rice productivity, yet many of the molecular mechanisms underlying this phenomenon remain largely unexplored.

OsMYB1 negatively mediates rice resistance to brown planthopper and rice blight. Additionally, OsMYB1 interacts with OsSPL14 and antagonizes its function by oppositely regulating downstream resistance-related genes. In their natural habitats, plants are concurrently attacked by different biotic factors.

Rice bacterial leaf blight, caused by pv (), is a significant threat to global food security. Although the microbiome plays an important role in protecting plant health, how the phyllosphere microbiome is recruited and the underlying disease resistance mechanism remain unclear. This study investigates how rice phyllosphere microbiomes respond to pathogen invasion through a comprehensive multiomics approach, exploring the mechanisms of microbial defense and host resistance.
