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. The results suggested auxin-cytokinins interplay driven by appears to be vital in disease progression by hampering the plant defense system. Taken together, our results indicate the possibility of using the phytohormone profile as a biomarker for BK resistance 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.

Melanin, a widespread pigment found in many taxa, is widely recognized for its high refractive index, ultraviolet (UV) protection, radical quenching ability, metal binding, and many other unique properties. The aforementioned characteristic traits make melanin a potential candidate for biomedical, separation, structural coloration, and space applications. However, the commercially available natural (sepia) and synthetic melanin are very expensive, limiting their use in various applications.

Plums are affected by a cancerous disease called "black knot disease" caused by the fungus . It affects both Japanese () and European () plums equally. To understand the spread of the disease, histological analysis was performed in two different European plum cultivars (susceptible and tolerant).
