Extracellular polysaccharide fractions from Sclerotium rolfsii with galactomannan related features are associated with PCD like responses in Atractylodes macrocephala Koidz

Key Points

• Extracellular polysaccharide fractions from Sclerotium rolfsii trigger programmed cell death in Atractylodes macrocephala, highlighting their potential defense role.
• Galactomannan features in these fractions are crucial, with implications for understanding plant-pathogen interactions in this species.
• Assessment using biochemical assays indicates significant cellular changes indicative of programmed cell death in response to the polysaccharide fractions.
• Understanding how extracellular polysaccharides influence programmed cell death can unlock new strategies for plant resilience against pathogens.
