Dehydrins are highly hydrophilic proteins involved in playing key adaptive roles in response to abiotic stress conditions having dehydration as a common component. In the present study, a novel banana SK(3)-type dehydrin, MusaDHN-1, was identified and later characterized using transgenic banana plants to investigate its functions in abiotic stress tolerance. Expression profiling in native banana plants demonstrated that MusaDHN-1 was induced in leaves by drought, salinity, cold, oxidative and heavy metal stress as well as by treatment with signalling molecules like abscisic acid, ethylene and methyl jasmonate. Promoter analysis carried out by making a MusaDHN-1 promoter: β-glucuronidase fusion construct reconfirmed the abiotic stress inducibility of MusaDHN-1. Transgenic banana plants constitutively overexpressing MusaDHN-1 were phenotypically normal and displayed improved tolerance to drought and salt-stress treatments in both in vitro and ex vitro assays. Enhanced accumulation of proline and reduced malondialdehyde levels in drought and salt-stressed MusaDHN-1 overexpressing plants further established their superior performance in stressed conditions. This study is the first to report generation of transgenic banana plants engineered for improved drought and salt-stress tolerance.

Background: Lead, a pervasive and toxic environmental pollutant, of particular concern is its impact as a trigger for neurodegenerative diseases. Phoenix dactylifera (date palm), has garnered attention due to its pharmacological properties: antioxidant and anti-inflammatory, attributed to its rich flavonoid content. This assessed the therapeutic potentials of n-butanol fraction of P.

Background: Sleep deprivation leads to an increase in oxidative stress and activation of inflammatory response and both could increase the production and accumulation of toxic beta-amyloid in the hippocampus which is considered one of the molecular drivers of Alzheimer's pathogenesis and progression. Despite these findings, obtaining sleep is still challenging in our modern society that values work around the clock. Omega-3 fatty acids represents an active biological agent with vital antioxidant and anti-inflammatory activities that could protect memory in the face of insufficient sleep.

Bananas are Ecuador's second largest non-oil export product, and the quality of its fruit has established a strong presence in international markets. One-third of the world's banana exports originate from Ecuador. The Ecuadorian banana market is diversified, exporting fruit to various countries worldwide, making it a vital socio-economic and food security support for the country.
