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.
Heterotrimeric G-proteins regulate plant growth and development as master regulators of signaling pathways. In legumes with indeterminate nodules (e.g.

Background And Aims: Recent findings indicate that Nod factor signalling is tightly interconnected with phytohormonal regulation that affects the development of nodules. Since the mechanisms of this interaction are still far from understood, here the distribution of cytokinin and auxin in pea (Pisum sativum) nodules was investigated. In addition, the effect of certain mutations blocking rhizobial infection and subsequent plant cell and bacteroid differentiation on cytokinin distribution in nodules was analysed.
