Salicylic and Jasmonic Acid Synergism during Black Knot Disease Progression in Plums.

Black knot (BK) is a deadly disease of European () and Japanese () plums caused by the hemibiotrophic fungus Generally, phytopathogens hamper the balance of primary defense phytohormones, such as salicylic acid (SA)-jasmonic acid (JA) balance, for disease progression. Thus, we quantified the important phytohormone titers in tissues of susceptible and resistant genotypes belonging to European and Japanese plums at five different time points. Our previous results suggested that auxin-cytokinins interplay driven by appeared to be vital in disease progression by hampering the plant defense system.

Effects of Genotype and Modified Atmosphere Packaging on the Quality of Fresh-Cut Melons.

Marketing melons () as convenient fresh-cut products is popular nowadays. However, damage inflicted by fresh-cut processing results in fast quality degradation and food safety risks. The life of fresh-cut produce can be extended by a modified atmosphere (MA), either generated in a package by tissue respiration (a passive MA) or injected by gas flushing (an active MA).

Hormonal Interplay Leading to Black Knot Disease Establishment and Progression in Plums.

Black Knot (BK) is a deadly disease of European () and Japanese () plums caused by the hemibiotrophic fungus . After infection, the appearance of warty black knots indicates a phytohormonal imbalance in infected tissues. Based on this hypothesis, we quantified phytohormones such as indole-3-acetic acid, tryptophan, indoleamines (N-acetylserotonin, serotonin, and melatonin), and cytokinins (zeatin, 6-benzyladenine, and 2-isopentenyladenine) in temporally collected tissues of susceptible and resistant genotypes belonging to European and Japanese plums during of BK progression.
