“…Total soluble phenols together with PPO appear to play a role in resistance to CLCuD, since these compounds were present in considerably higher levels in leaves of CLCuBuV-inoculated cotton plants of resistant genotypes. This is supported by the work of Li and Steffens (2002), Thipathi and Verma (1975), Kumar et al (1991), and Ngadze et al (2012).…”

Leaf curl disease caused by Cotton Leaf Curl Burewala virus (CLCuBuV) has been recognized as serious threat to cotton in Indian subcontinent. However, information about cotton-CLCuBuV interaction is still limited. In this study, the level of phenolic compounds, total soluble proteins, and malondialdehyde (MDA) and the activities of phenylalanine ammonia-lyase (PAL), peroxidase (POX), catalase (CAT), proteases, superoxide dismutase (SOD), and polyphenol oxidase (PPO) were studied in leaves of two susceptible (CIM-496 & NIAB-111) and two resistant (Ravi and Co Tiep Khac) cotton genotypes. Disease symptoms were mild in the resistant genotypes but were severe in highly susceptible genotypes. The results showed that phenolic compounds, proteins, PAL, POX, CAT, proteases, SOD, PPO, and MDA play an active role in disease resistance against CLCuBuV. The amount of total phenols, proteases, MDA, and PPO was significantly higher in leaves of CLCuBuV-inoculated plants of both resistant genotypes as in non-inoculated plants, and decreased in CLCuBuV-inoculated plants of both susceptible genotypes over their healthy plants. POX, protein content, SOD, and PAL activities showed lower values in resistant genotypes, while they decreased significantly in susceptible genotypes as compared to the noninoculated plants except PAL, which showed non-significant decrease. CAT was found to be increased in both susceptible and resistant genotypes with maximum percent increase in resistant genotype Ravi, as compared to non-inoculated plants. The results showed significantly higher concentrations of total phenols and higher activity of protease, MDA, SOD, and PPO in resistant genotype Ravi after infection with CLCuBuV, suggesting that there is a correlation between constitutive induced levels of these enzymes and plant resistance that could be considered as biochemical markers for studying plant-virus compatible and incompatible interactions.

“…They have antibacterial effects and inhibit growth of soft rot bacteria (Ghanekar et al, 1984;Kumar et al, 1991). Chlorogenic acid is produced as a defense in potatoes in response to infection or injury (Ghanekar et al, 1984).…”

“…Chlorogenic acid is produced as a defense in potatoes in response to infection or injury (Ghanekar et al, 1984). Caffeic acid is known to inhibit the growth of soft rot bacteria (Kumar et al, 1991). The combination of caffeic acid and chlorogenic acid may significantly inhibit infection by soft rot pathogens (Ghanekar et al, 1984;Kumar et al, 1991).…”

“…Phenolics may function by directly inhibiting bacterial growth, by inhibiting wall-degrading enzymes, or as precursors in the formation of physical barriers such as lignin. Kumar et al (1991) showed an inverse relationship between percentage tuber rotting of six cultivars and total phenolics after incubating naturally infected tubers in a well ventilated room at temperatures varying between 26 and 37 ~ (these temperatures are higher than that favoring accumulation of high levels of sesquiterpene phytoalexins). Kumar et al (1991) also showed that high levels of nitrogen fertilizer increased the susceptibility of tubers to rotting, although this increase in susceptibility was not associated with a significant decrease in total phenolics.…”
