“…In previous studies, the value of chlorophyll a in the mistletoe has been shown to be significantly lower than hosts. The invasion of parasite in the mango (host) has also been reported to alter the ratio between chlorophyll a and b, probably affecting the photosynthetic efficiency [9,12,30,31]. In our study, chlorophyll a content of mistletoe was found to be higher than chlorophyll b wihile Oyetunji and Edagbo [18] showed that both host (Citrus, Irvingia) and African mistletoe (Tapinanthus bangwensis) have higher chlorophyll b contents.…”

Abstract:In this study, leaf proportional water content, chlorophyll a and b, total chlorophyll, carotenoid, proline, total amino acid, ascorbic acid, glucose, fructose and sulphydryl group (SH) were determined in both Viscum album ssp. album and its hosts. Physiological alterations in soft-core fruits such as Ankara pear, Braeburn apple and hawtorn when infected with Viscum album ssp. album were investigated. While proportional water content of V. a. ssp. album was found higher than all fruit trees with or without V. album (control), its chlorophyll a content was lower than only control and two hosts (Braeburn apple and Ankara pear). Chlorophyll b content, on the other hand, was similar in all experimental groups for Ankara pear and hawthron whereas, in Braeburn apple, it was significantly higher in control. As for the total chlorophyll and carotenoid contents of V.a. ssp. album, in Breaburn and Ankara pear, they were found less than the controls and hosts whilst in hawthorn, the values were variable. Although proline content of V. a. ssp. album was higher compared to their controls and hosts, total amino acid, reduced and total ascorbic acid, glucose, fructose and sulphydryl acid in V. a. ssp. album were determined to be lower than all uninfected fruits (control).

“…plantarum GR53 treatment attenuated that consequence. Thimmaiah (1999) and Chatterjee and Ghosh (2008) suggested that the inhibition of phenolic compounds synthesis in plants during pathogen infection indicates the susceptibility of plants. The lower level of phenolic content in R. solani-infected Chinese cabbage plants revealed that this cultivar was susceptible to R. solani induced disease.…”

The fungus Rhizoctonia solani is one of the causal agents of numerous diseases that affect crop growth and yield. The aim of this present investigation was to identify a biocontrol agent that acts against R. solani and to determine the agent's protective effect through phytohormones and antioxidant regulation in experimentally infected Chinese cabbage plants. Four rhizospheric soil bacterial isolates GR53, GR169, GR786, and GR320 were tested for their antagonistic activity against R. solani. Among these isolates, GR53 significantly suppressed fungal growth. GR53 was identified as Bacillus amyloliquefaciens subsp. plantarum by phylogenetic analysis of the 16S rDNA sequence. The biocontrol activity of B. amyloliquefaciens subsp. plantarum GR53 was tested in Chinese cabbage plants under controlled conditions. Results showed that R. solani inhibited plant growth (length, width, fresh and dry weight of leaves) by reducing chlorophyll and total phenolic content, as well as by increasing the levels of salicylic acid, jasmonic acid, abscisic acid, and DPPH scavenging activity. By regulating the levels of these compounds, the co-inoculation of B. amyloliquefaciens subsp. plantarum GR53 heightened induced systemic resistance in infected Chinese cabbage, effectively mitigating R. solani-induced damaging effects and improving plant growth. The results obtained from this study suggest that B. amyloliquefaciens subsp. plantarum GR53 is an effective biocontrol agent to prevent the damage caused by R. solani in Chinese cabbage plants.

“…These results suggest that the presence of PWV can affect the content of antioxidant molecules in rinds. It is well established that the profile of phenolic compounds can vary in plants infected by fungal pathogens, insects and viruses (Chatterjee & Ghosh, 2008;Lattanzio, Lattanzio, & Cardinal, 2006). PWV currently affects passion fruit plants in Brazil, where it is the most economically important viral disease of this tropical fruit crop.…”

The antioxidant activity of methanol extracts from Passiflora edulis and Passiflora alata pulp, and P. edulis rinds, healthy or infected with the passion fruit woodiness virus (PWV), was investigated using the oxidant activities of the neutrophil and the neutrophil granule enzyme myeloperoxidase (MPO), both playing key roles in inflammation. The reactive oxygen species produced by stimulated neutrophils were evaluated by lucigenin-enhanced chemiluminescence (CL) and the activity of purified MPO was measured by SIEFED (Specific Immunological Extraction Followed by Enzymatic Detection), a technique for studying the direct interaction of a compound with the enzyme. The rind extracts of P. edulis possessed higher and dose-dependent inhibitory effects on CL response and on the peroxidase activity of MPO than total pulp extracts from both passion fruit species. The quantification of isoorientin in the extracts showed a correlation with their antioxidant activity, suggesting the potential of P. edulis rinds as functional food or as a possible source of natural flavonoids.
