Influence of Enhanced Synthesis of Exopolysaccharides in Rhizobium ruizarguesonis and Overproduction of Plant Receptor to these Compounds on Colonizing Activity of Rhizobia in Legume and Non-Legume Plants and Plant Resistance to Phytopathogenic Fungi.
Curr Microbiol
October 2024
Rhizobial exopolysaccharides (EPS) may provide stabilization of membranes against external factors, as well as improved surface adhesion, but their role in interaction with legume and non-legume plants is still far from understanding. In this work, the transcriptional regulator RosR of Rhizobium ruizarguesonis, which regulates the synthesis of EPS, was overproduced in a pHC60 plasmid and expressed in the RCAM 1026 strain. This resulted in an improved production of EPS by this recombinant strain.

Article Synopsis
- Chitooligosaccharides (COs) are biodegradable and non-toxic, making them potential agents for plant protection, but their exact mechanisms of action are still unclear.
- This study used RNA sequencing to investigate the transcriptional changes in pea roots after treatment with CO8-DA, identifying 886 differentially expressed genes that suggest the involvement of calcium signaling and MAPK pathways in the plant's response.
- The research also highlights specific MAPKKKs, PsMAPKKK5 and PsMAPKKK20, which appear to work together in the signaling pathway activated by CO8-DA and are essential for improving the plant's resistance to pathogenic fungi.
Objectives: To review available health and nutrition claims for infant formula products in multiple countries and to evaluate the validity of the evidence used for substantiation of claims.

Setting: Public facing and healthcare professional facing company owned or company managed formula industry websites providing information about products marketed for healthy infants delivered at full term in 15 countries: Australia, Canada, Germany, India, Italy, Japan, Nigeria, Norway, Pakistan, Russia, Saudi Arabia, South Africa, Spain, the United Kingdom, and the United States in 2020-22.
Article Synopsis
- Regulation of plant hormonal status is crucial for nodule formation in legumes, but the genetic and hormonal networks involved in nodule differentiation are not well understood.
- Researchers explored the effects of cytokinin on nodule development using pea mutants with impaired rhizobial infection, finding that cytokinin increased nodule size and stimulated bacterial release.
- A transcriptome analysis identified key regulatory factors, including CCS52, EFD, SYMREM, and others, which play roles in nodule differentiation, confirmed through real-time PCR testing after cytokinin treatment.
Heterotrimeric G-proteins regulate plant growth and development as master regulators of signaling pathways. In legumes with indeterminate nodules (e.g.
