Journal of soil science and plant nutrition, Год журнала: 2023, Номер 24(1), С. 54 - 73

Опубликована: Дек. 26, 2023

Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

Comparative Efficacy of Trichoderma harzianum and Pseudomonas putida in Mitigating Verticillium Wilt of Brassica napus

ABSTRACT Verticillium dahliae is a devastating pathogen that causes wilt of Brassica napus . This study investigated the application Pseudomonas putida and Trichoderma harzianum as biocontrol agents against V. , their impact on growth B. was studied. In vitro, dual‐culture assays revealed significant mycelial inhibition by both T. (96%) P. (83%). For in vivo studies, fungus ( ) directly introduced into ‐infested soil, seeds were sown (T + VD). inoculation with bacteria, primed –infested soil (P Both treatments significantly improved physiological parameters (seed germination, root length, shoot relative water content chlorophyll contents) decreased electrolyte leakage oxidative burst (malondialdehyde, H 2 O ). These also increased concentrations osmolytes (proline sugar content) enhanced enzymatic activities (catalase, peroxidase superoxide dismutase). After 21 days control treated plants (inoculated only or displayed no wilting symptoms. dahliae– inoculated severe symptoms wilting, lower leaves turned yellow showed curling. Treatment T VD almost disease symptoms, while treatment P exhibited negligible Histological analysis colonisation vascular system treatments. findings successfully demonstrated significance for controlling

Clubroot, a devastating soil borne disease affecting 30%∼50% of Brassicaceae crops worldwide, lacks effective control measures. In the present study, we explored potential melatonin (MT) and copper oxide nanoparticle (CuO-NPs) in mitigating clubroot severity Brassica rapa ssp. pekinensis. Following 18 h priming with MT, CuO-NPs, or both seeds were grown controlled environment using synthetic potting mix. Inoculated Plasmodiophora brassicae spores on 5th day, followed by drench phyto-nano treatment week interval. Plants assessed for various health growth indices including disease, biometrics, photosynthesis, reactive oxygen species (ROS), antioxidant enzyme activity, hormones genes expression at onset secondary infection established protocols. Statistical analysis employed ANOVA Fisher's LSD significance assessment (P < 0.05). Our results revealed that seed MT (50 μMol/L) CuO-NPs (200 mg/L), drenching significantly reduced incidence (38%) index (57%), compared to treatments. This synergistic effect was associated enhanced plant (shoots: 48% roots: 59%). treated showed robust defenses, increased superoxide dismutase (SOD (25/29%)), catalase (CAT (83/55%)), ascorbate peroxidase (APX (83/46%)) activity shoots/roots, respectively, infected control. Notably, salicylic acid jasmonic levels doubled plants, while stress hormone abscisic (ABA) decreased 80% roots 21% shoots. Gene corroborated these findings, showing combined activated defense (SOD, APX CAT) 1.9-7.2-fold upregulated signaling JAZ1 (7.8-fold), MYC2 (3.9-fold) SABP2 (36-fold). Conversely, ABA biosynthesis (ABA1 NCED1) downregulated up 7.2-fold, resistance NPR1, PRB1 PDF1.2 dramatically 6.3-fold plants. Overall, our approach reduces B. via improved ROS scavenging, coordinated hormonal regulation pathogen response genes. study offers promising strategy developing measures against susceptible cruciferous crops.

New Trichoderma Strains Suppress Blue Mold in Oranges by Damaging the Cell Membrane of Penicillium italicum and Enhancing Both Enzymatic and Non-Enzymatic Defense Mechanisms in Orange Fruits

Horticulturae, Год журнала: 2024, Номер 10(10), С. 1076 - 1076

Опубликована: Окт. 8, 2024

Blue mold disease, caused by Penicillium italicum (P. italicum), presents a significant challenge to orange fruits (Citrus sinensis L.) and other citrus crops globally. Biological control, particularly Trichoderma species, offers promising alternative synthetic fungicides. Therefore, this study aimed isolate, identify, evaluate the antagonistic activities of two isolates against P. italicum. These were molecularly identified assigned accession numbers PP002254 PP002272, respectively. Both demonstrated antifungal activity in dual culture assays. Moreover, filtrates (CFs) longibrachiatum harzianum PP002272 suppressed mycelial growth 77.22% 71.66%, Additionally, CFs reduced severity blue on 26.85% 53.81%, compared 100% control group. Scanning electron microscopy revealed that treated hyphae shrunken disfigured. Enzyme (catalase, peroxidase, polyphenol oxidase, phenylalanine ammonia-lyase) oranges increased, along with total soluble phenolics flavonoids. Conversely, malondialdehyde (MDA) levels decreased fruits. findings suggest T. could be effective biocontrol agents for managing postharvest diseases.
