Summary
Chitooligosaccharide enhances plant resistance to various stresses like drought and pathogens without causing harm. This review details its mechanisms and future research directions for improved crop resilience.
Area of Science:
- Plant Science
- Biotechnology
- Agriculture
Background:
- Extreme environmental conditions can irreversibly damage plants, hindering agricultural production.
- Phytostimulants offer a method to enhance plant stress resistance without causing damage.
- Chitooligosaccharide (COS) is a notable phytostimulant with proven benefits for plant growth and stress tolerance.
Purpose of the Study:
- To review and summarize research on chitooligosaccharide-induced plant stress resistance.
- To classify and discuss the mechanisms of COS-induced resistance against various environmental stresses.
- To identify challenges and propose future research directions for COS applications in agriculture.
Main Methods:
- Literature review and synthesis of existing research on chitooligosaccharide.
- Classification of experimental findings on COS-induced resistance to pathogen, drought, low-temperature, and saline-alkali stresses.
- Analysis of the underlying molecular and physiological mechanisms.
Main Results:
- Chitooligosaccharide effectively primes plant defense mechanisms against a range of abiotic and biotic stresses.
- COS application promotes seed germination, plant growth, development, and photosynthesis.
- Specific mechanisms of COS-induced resistance vary depending on the stress type.
Conclusions:
- Chitooligosaccharide is a promising sustainable solution for improving plant stress tolerance and agricultural productivity.
- Further multidisciplinary research is needed to fully elucidate COS mechanisms and optimize its application.
- Addressing current challenges will pave the way for advanced applications of COS in plant science.

Adaptations that Reduce Water Loss
25.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
