Towards Uncovering New Insights into Respiratory Inhibitor Fungicide Resistance in Molinia Fungal Plant Pathogens: Insights from a Mitogenomic Approach Full text
2025
Kübra Arslan | Muhammed Raşit Durak | Hilal Özkılınç
Mitochondrial genomes are key targets in controlling fungal plant pathogens and mediate adaptive responses like fungicide resistance. Respiratory inhibitor fungicides (RIs) are widely used against many fungal pathogens, including Monilia fructi cola and M. lax, which are casual agents of brown rot of stone fruits worldwide. Although resistance to RIs has been reported in these species, the genetic basis is not fully elucidated. and is hypothesized to involve mitochondrial genome variations. To explore this, mitogenomic variations was comprehensively analysed to assess the resistance responses of two Monilia species to three RIs, including two technical grade fungicides (bosclid and azoxystrobin) and, a commercial one (signum). Whole mitogenome data from sixteen isolates of two species with different resistance/susceptibility phenotypes were analysed for certain gene mutations, mitochondrial variants, heteroplasmy, and sequence kernel associations. The results indicated that commonly known mutations and low levels of heteroplasmy do not fully explain resistance. In Monilinia fructicola, the presence of multiple variants appears to contribute to resistance, however, no variant patterns corresponded significantly with resistance phenotype in M. laxa. Providing a broad perspective, this study serves as a valuable model and supports the potential of mitogenome-focused RI resistance research. These insights contribute to a better understanding of specific resistance responses, thereby supporting the development of more effective pathogen control strategies.

Microgreens have become popular due to the positive health and high nutritional value effects of the bioactive compounds they contain. This study aimed to determine the total phenolic, flavonoid and antioxidant contents of red radish and parsley microgreens and to evaluate their anticancer effects in chronic lymphocytic leukemia cells (CLL). After methanolic extraction of microgreens, DPPH, radical scavenging activity and total polyphenol and flavonoid content were analyzed spectrophotometrically. The effects of microgreens on MEC-1 and HG-3 CLL cell lines were determined by MTT method. The methanolic total flavonoid content of red radish and parsley microgreens were 2,562 mg/g RE and 1,306 mg/g RE, respectively; total polyphenol contents were 4,133 mg/g GAE and 1,851 mg/g GAE, respectively; DPPH radical scavenging activity were 701,423 µg/g GAE and 625,717 µg/g GAE, respectively. The IC50 concentrations were found 70 mg/ml and 75 mg/ml for parsley microgreen for MEC-1 and HG-3 cell lines, respectively; 65 mg/ml for red radish microgreen for MEC-1 cells, while more cell proliferation was observed at the doses applied for HG-3 cells. Higher antioxidant content was found in microgreen radish than in parsley. Methanolic microgreen extracts significantly reduced cell proliferation in CLL cell cultures at varying levels. Of interest in terms of potential antitumor effects, microgreen radish extracts, which are rich in polyphenol content, showed a proliferative effect on wild-type CLL cells. In conclusion, this study is important in terms of revealing the activities of various microgreens, particularly radish and parsley microgreens, and detailing their benefits on human health.

The study produced milk drink that is high in protein and energy from soy beans and tiger nuts blends as well as to assess the beverage qualitatively and customer acceptability using response surface methodology (RSM). The principal raw materials used were soybeans and tiger nut. They were processed into milk at different formulations without using chemical preservative. Sensory evaluation, pH, titratable acidity as well as proximate and mineral compositions were determined. The results showed that the minimum and maximum colour score varied from 4.4 to 5.0. The quadratic model for colour was found to be significant (p<0.05) in tiger nut inclusion. The model equation obtained for colour = 4.50 + 0.048*A + 0.098*B + 0.019*A2 + 0.12*B2 + 0.18*A*B where A = Soybeans, B = Tiger nut. Mouth feel model’s F-value of 7.35 indicates that it was significant (p<0.05). Model terms are considered important when the “Probability > F” value was less than 0.05. The model for quadratic equation for mouth feel was 7.290. +5.00 -0.091*A -0.19*B -0.14* A2 -0.44* B2 +0.45* A*B. The model for the quadratic equation for Taste = +3.90 +0.030*A +0.020* B +0.21*A2 +0.056*B2 +0.075*A*B adequate precision = 3.65, corrected R2 = 0.29, R2 = 0.59 and the predicted R2 = -1.94. It was observed the pH values decreases with storage days from day 0 to day 8 for samples A, I and Z. On day 12, the pH values increased for all the samples except for sample M. The Titratable acid increased as the pH decreased. On the 0 day, sample A had value of 20.8 while sample M was 23.33. However, sample I increased from 0, 4, 8 and 12 days (20.19, 20.20, 22.47 and 23.73) respectively. Sample M had the highest protein content (3.52%), followed by sample A (3.21%), sample I (3.01%) and sample Z (2.02%). Sample Z had the lowest fiber content (0.30%), next was sample I (O.43 %), sample A (0.51%), and sample M (0.54%). The range of moisture contents was 81.03 to 82.04%. Conclusively, optimizing soybeans at 100g/ml with 40 g/ml of tiger nut could help to improve the sensory attributes such as colour, taste, mouth feel, flavor and overall acceptance. The formulation could influence shelf stability of product, bridge protein in-balance and reduction in malnutrition level.

Promoting rooftop farming using suitable grow bag media is of utmost importance in densely populated cities like Lalitpur to sustain the human race. To assess the productivity and other economic characteristics of bell peppers, an experiment was conducted from Feb 2022 to Jun 2022 in different grow bag media on the premises of Vegetable Crop Development Centre, Khumaltar, Lalitpur. The experiment was conducted in Randomized Complete Block Design (RCBD), with four replications and five treatments with growing media: Coco peat: vermicompost (1:1), Soil: sand: FYM (Farmyard Manure) (1:1:1), Soil: Sand: FYM: Vermicompost (1.25:0.75:0.5:0.5), Soil: vermicompost (1:1), and Soil: ash: FYM (1:0.5:1) on the cultivar California Wonder. Growth parameters like plant height (47.865 cm), number of leaves (50.6), number of branches/plant (9.5), and stem diameter, and yield parameters like total fruit weight (1693.93 gm), average fruit weight (84.68 gm), number of fruits (42.75), fruit diameter (6.37 cm), and fruit length (7.22 cm) were observed during the experiment. The media consisting of T3 (Soil: Sand: FYM: Vermicompost (1.25:0.75:0.5:0.5)) proved to be statistically superior over the rest of the combinations for almost all aspects under investigation, whereas comparatively poor performance was observed in Coco peat: vermicompost (1:1) media. This study suggests that the grow bag media of Soil: Sand: FYM: vermicompost (1.25:0.75:0.5:0.5) gave the highest gross return and net return, with the highest B: C ratio (2.08) observed in the grow bag media of Soil: Sand: FYM (1:1:1).

The objective of this study was to evaluate the effects of palm oil, African walnut oil and their blends on hematological, inflammatory, and some oxidative stress markers in high fat diet (HFD) obese-induced Wistar rats. Obesity was induced for 60 days and treated for 28 days using edible oils [palm oil, African walnut oil, palm oil: African walnut oil (50:50) and palm oil : African walnut oil (60:40)] and orlistat (10 mg/Kg). Thereafter the animals were sacrificed, blood was collected for hematological studies and the preparation of the serum, while the organs harvested were used to prepare organ homogenates. Serum and organ homogenates were used for the evaluation of inflammation and oxidative stress markers. Results showed that the oils utilized were confirmed to be of high quality through their good stability indices (peroxide value: 2.52-3.87meq O2/Kg; p-anisidine value: 8.24-12.33, TOTOX value: 13.37-19.46,). Looking at the haematological study, animals that received the HFD presented the lowest (p<0.05) hematocrit and Platelet. PO:WO (50:50 and 60:40) significantly (p<0.05) decreased the granulocytes concentration in the blood of rats. PO:WO (50:50) significantly (p<0.05) increased the lymphocyte concentration while 100% PO increased the mid-size white blood cells level in the animals. Serum levels of inflammation markers were higher (p<0.05) in the negative control group (354.44-385.82 pg/mL) compared to the other groups (147.22-271.55 pg/mL). The analysis of oxidative stress parameters revealed that the administered oils and orlistat generally exhibited good protections compared to the normal and negative control groups, which might be due to the presence of omega-3 fatty acids and bioactives such as β-carotene and vitamin E which have good antioxidant and anti-inflammatory properties. It can be concluded that these oils have a role in protecting against obesity through their effects on oxidative stress, hematology, and inflammatory cytokines.
