Aims: Melon Manis Terengganu, MMT is one of the economically important fruits in Terengganu, which contains numerous nutritional values and bioactive compounds that benefit human health. The major problem is MMT has been affected by Fusarium sp., which is the common fungus in the Cucurbitaceae family resulting in Fusarium wilt disease and lowering melon production. It may also affect the antioxidant value of MMT; however, limited study has been conducted on this issue. Hence, the objective of this study was to determine the non-enzymatic as well as enzymatic activities in response to Fusarium sp. (S2 and S4) infection. Methodology and results: In this study, MMT leaves were incubated in culture filtrate (CF) obtained from Murashige and Skoog (MS) liquid medium. The antioxidative responses were assayed at 0, 1, 3, 5, 7 and 9 days of treatment. In response to Fusarium infection, the ascorbic acid, α-tocopherol and carotenoid content were significantly stimulated at the early stages of the experiment and slowly reduced afterward. This current study also demonstrated that the CATspecific activities were initially induced in S2 CF-treated leaves. Similar APX and gPOD specific activity patterns were observed in both S2 and S4 CFs treatments. The APX and gPOD-specific activities were induced at the later stages of infection in S4 CF-treated leaves. Conclusion, significance and impact of study:The results revealed that enzymatic and non-enzymatic antioxidants worked together to fight against stress caused by the fungal infection, with the activation of the plant defense system.

A Review on Natural Antioxidants for Their Role in the Treatment of Parkinson’s Disease

The neurodegenerative condition known as Parkinson’s disease (PD) is brought on by the depletion of dopaminergic neurons in the basal ganglia, which is the brain region that controls body movement. PD occurs due to many factors, from which one of the acknowledged effects of oxidative stress is pathogenic pathways that play a role in the development of Parkinson’s disease. Antioxidants, including flavonoids, vitamins E and C, and polyphenolic substances, help to reduce the oxidative stress brought on by free radicals. Consequently, this lowers the risk of neurodegenerative disorders in the long term. Although there is currently no cure for neurodegenerative illnesses, these conditions can be controlled. The treatment of this disease lessens its symptoms, which helps to preserve the patient’s quality of life. Therefore, the use of naturally occurring antioxidants, such as polyphenols, which may be obtained through food or nutritional supplements and have a variety of positive effects, has emerged as an appealing alternative management strategy. This article will examine the extent of knowledge about antioxidants in the treatment of neurodegenerative illnesses, as well as future directions for research. Additionally, an evaluation of the value of antioxidants as neuroprotective agents will be provided.

“…The genotypes RGC 936 and HG-563 showed the lowest activity at 72 hapi. The accumulation of hydrogen peroxide in primary leaves around appressoria was reported to limit the fungal penetration and mediate defence activities [Barreto et al, 2007;Lehmann et al, 2015, Mahadik andMali (2018)].…”

Background: Leaf blight caused by Alternaria spp. is one of the serious concerns in guar production worldwide. Despite this, the interaction of host-pathogen and responses of different guar genotypes against necrotrophic fungus Alternaria is still not much explored. Methods: In the present investigation, six guar genotypes have been infected with Alternaria and observed differential responses by using various parameters, including biochemical assays, antioxidant activities (SOD, CAT, PO, GPx, APx PAL, β-1,3-glucanase enzyme, total phenolic content) and physiological parameters (chlorophyll content, carotenoid and photosynthetic yield-II). Result: After the pathogenicity of Alternaria there was a substantial shift in the biochemical activity in all the inoculated resistant genotypes compared to their respective controls. Moreover, a significant reduction was also observed up to 65% in terms of physiological performance, such as total chlorophyll content, carotenoids and photosynthetic yield-II content, after 14 days of pathogenicity. The genotypes RGC-1066 and RGC-936 showed relatively more resistance and RGC-936 showed relatively more susceptibility towards Alternaria infection. These findings also imply that host-pathogen interactions factors have a role in the differential expression of defence-related enzymes and antioxidant activities in response to Alternaria inoculation.
