“…Chitosan induces PRPs, especially chitinase and glucanase, in several crops, including grape (V. vinifera L.; Trotel-Aziz et al, 2006), pear (Pyrus pyrifolia (Burm. f.) Nakai; Meng et al, 2010), papaya (C. papaya L.; Ali et al, 2012;Hewajulige et al, 2009), peach (Prunus persica (L.) Batsch; Ma et al, 2013), tomato (Sathiyabama et al, 2014), dragon fruit (Hylocereus undatus (Haworth) Britton & Rose; Ali et al, 2014), and coconut (Cocos nucifera L.; Lizama-Uc et al, 2007). The increase in glucanase or chitinase levels was associated with the increased disease resistance, suggesting that the chitosan-induced disease resistance was potentially based on the induction of these enzymes.…”

“…Most notably this includes chitinases, but also includes glucanases [68] peroxidases, polyphenoloxidases [124] and MAP-kinases [132]. Protease inhibitors are also produced [118]; presumably to limit the activity of the pathogen's own enzymes involved in attack.…”

Abstract:In recent decades, a greater knowledge of chitin chemistry, and the increased availability of chitin-containing waste materials from the seafood industry, have led to the testing and development of chitin-containing products for a wide variety of applications in the agriculture industry. A number of modes of action have been proposed for how chitin and its derivatives can improve crop yield. In addition to direct effects on plant nutrition and plant growth stimulation, chitin-derived products have also been shown to be toxic to plant pests and pathogens, induce plant defenses and stimulate the growth and activity of beneficial microbes. A repeating theme of the published studies is that chitin-based treatments augment and amplify the action of beneficial chitinolytic microbes. This article reviews the evidence for claims that chitin-based products can improve crop yields and the current understanding of the modes of action with a focus on plant-microbe interactions.

“…As cell culture systems are relatively easy to manipulate by empirical means, these can provide a better control of external factors that can interfere with the metabolic activities, and thus advantageous over studies on in vivo plant-pathogen interactions (Stratmann et al, 2000). In the recent past, many elicitorinduced cell cultures of different plant species were used as model systems to understand plant-pathogen interactions both at biochemical and molecular levels (Lizama-Uc et al, 2007;Shein et al, 2003).…”
