MetabolomicsIntegrated microbiome and metabolome profiling reveals rhizosphere responses to chitosan application in tobacco
Chitosan is widely investigated as a plant biostimulant, but its effects on the rhizosphere microbiome and metabolome under field conditions remain poorly understood. Here, we evaluated the response of the tobacco (Nicotiana tabacum L.) rhizosphere to chitosan root-drench treatment by integrating ba...

MetabolomicsMolecular Omics Unveils the Antimicrobial Mechanism of UV-LED-Induced Chitosan Composite Film Against Penicillium itali-cum

Penicillium italicum (P. italicum) is a primary pathogen responsible for postharvest decay in citrus fruits, resulting in substantial economic losses. Chitosan and titanium dioxide and silver (CTS&TiO2&Ag) composite film solutions activated by combined UV and LED light represent innovativ...

TranscriptomicsTranscription profiling of Arabidopsis seedlings treated with chitosan
We treated Arabidopsis seedlings with chitosan and carried out a transcript profiling analysis (GeneChip microarrays) in order to identify genes and transcription factors regulated by chitosan. The results showed that jasmonate and defense responsive genes, camalexin and lignin biosynthetic genes we...

TranscriptomicsInsight into the response of Bacillus cereus towards the polysaccharide chitosan
Comparison of chitosan-treated B. cereus ATCC 14579 cells with non-treated B. cereus ATCC 14579 cells. 2 chitosans with similar molecular weight (Mw) but different degrees of acetylation (Fa) were used: chitosan B (Mw: 28.4 kDa, Fa: 0.16) (samples 1-3) and chitosan A (Mw: 36.0 kDa, Fa: 0.01) (sample...

TranscriptomicsChitosan-affected gene expression profiles in brain and stomach
Chitosan has been widely used in food industry as a weight-loss aid and a cholesterol-lowering agent. Previous studies have shown that chitosan affects metabolic responses and contributes to anti-diabetic, hypocholestermic, and blood glucose-lowering effects; however, the in vivo targeting sites and...

TranscriptomicsChitosan primes plant defence mechanisms against Botrytis cinerea including Avr9/Cf-9 rapidly-elicited genes
Current protection strategies against the fungal pathogen Botrytis cinerea rely on a combination of conventional fungicides and host genetic resistance. Defence elicitors can stimulate plant defence mechanisms through a phenomenon known as priming. Priming results on a faster and/or stronger express...

ProteomicsArabidopsis Col-0 and cerk1 treated with chitosan or water
Microbe-associated molecular pattern (MAMP)-triggered immunity (MTI) is the first layer of molecular defense encountered by pathogens when they attempt to infect plants. MTI is dependent on cell surface pattern-recognition receptors (PRR) which act upstream of mitogen-activated protein kinase (MAPK)...

ProteomicsThe moss Physcomitrella patens secretome peptides under chitosan treatment
Taking into account that immune signaling peptides are often species-specific and cannot be predicted based on similarity search, we performed mass spectrometry analysis of the P. patens secretomes. Since the moss P.patens is unable to perceive the known bacterial elicitors such as flagellin or elf1...
