ABSTRACT Plants recognize a variety of environmental molecules, thereby triggering appropriate responses to biotic or abiotic stresses. Substances containing microbes-associated molecular patterns (MAMPs) and damage-associated (DAMPs) are representative inducers pathogen resistance damage repair, thus treatment healthy plants with such substances can pre-activate plant immunity cell repair functions. In this study, the effects DAMP/MAMP oligosaccharides mixture (Oligo-Mix) derived from wall (cello-oligosaccharide xylo-oligosaccharide), fungal (chitin-oligosaccharide) were examined in cucumber. Treatment cucumber Oligo-Mix promoted root germination growth, along increased chlorophyll contents leaves. also induced typical defense as MAP kinase activation callose deposition Pretreatment enhanced disease leaves against pathogenic fungi Podosphaera xanthii (powdery mildew) Colletotrichum orbiculare (anthracnose). induction hypersensitive death around infection site pathogens, which inhibited further conidial formation pathogens on RNA-seq analysis revealed that upregulated genes associated structural reinforcement, stresses defense. These results suggested has beneficial growth cucumber, making it promising biostimulant for agricultural application.

Pattern-Triggered Immunity (PTI) in plants is activated upon recognition by Pattern Recognition Receptors (PRRs) of Damage- and Microbe-Associated Molecular Patterns (DAMPs MAMPs) from or microorganisms, respectively. An increasing number identified DAMPs/MAMPs are carbohydrates plant cell walls microbial extracellular layers, which perceived PRRs, such as LysM Leucine Rich Repeat-Malectin (LRR-MAL) receptor kinases (RKs).

Mechanical forces can affect chemical reactions in a way that thermal cannot do, which may have variety of applications. In biomass conversion, the selective conversion cellulose and chitin is grand challenge because they are top two most abundant resources recalcitrant materials insoluble common solvents. However, recent works clarified mechanical enable depolymerization these polysaccharides, leading to production corresponding monomers oligomers.
