Temporal and spatial assessment of defense responses in resistant and susceptible cabbage varieties during infection with Xanthomonas campestris pv. campestris

Effects of 1-MCP and exogenous ethylene on fruit ripening and antioxidants in stored mango

“…Samples from every treatment were taken at intervals for ACC concentration and ACO activity assay. Bars indicate standard deviation of the mean (n = 3) treatment may be attributed to the blockage of ethylene receptor compared with exogenous ethylene treatment, which prevents downstream ethyleneinduced effects (Sisler and Serek 1997 (Foyer et al 1997). H 2 O 2 played an important role in regulating the ripening or senescence course of fruits and vegetables (Hodges and Forney 2000).…”

The possible involvement of peroxidase in defense of yellow lupine embryo axes against Fusarium oxysporum

“…In the course of the pathogenplant interaction, peroxidases are key enzymes in the detoxification systems, involved in scavenging reactive oxygen forms, whose increased generation is closely associated with the induction of plant defense reactions (Gay and Tuzun, 2000). They are also involved in the oxidation of isophenols to forms that are more toxic towards the pathogens (Takahama and Hirota, 2000) and in the cross-linking of cell wall proteins and lignification of cell walls (Gay and Tuzun, 2000;Lagrimini and Rothstein, 1987). This may limit the penetration of pathogen toxins into the cells and thus the spread of the infection (Lurie et al, 1997).…”

Heterosis for superoxide dismutase, peroxidase and catalase enzymes in the head of single cross-hybrids of cabbage (Brassica oleracea var. capitata)

“…* Significant at P < 0.05) improve crop stand, tolerance to stresses, diseases and pests, and shelf life of head. It is well established that the inherent antioxidant systems would help to scavenge the detrimental effects of ROS and contribute towards stress tolerance (Bowler et al 1992;Zambounis et al 2002;Yiu and Tseng 2005), extension of shelf life of produce and inhibition of senescence and ageing (Zhuang et al 1995;Toivonen and Sweeney 1998;She et al 2003), tolerance to black rot (Gay and Tuzun 2000), etc.…”
