Osmopriming-associated genes in Poincianella pyramidalis

Environmental and Experimental Botany, 2021
Osmopriming of seeds can increase seed vigour, allowing faster germination and field emergence, especially under adverse field conditions. The restricted imbibition during priming treatments reactivates metabolism although germination will be prevented.

Influence of arbuscular mycorrhizal fungi density on growth and metabolism of Handroanthus serratifolius (Vahl) S.O. Grose seedlings

Physiologia Plantarum, Volume 175, Issue 6, November/December 2023., 2023
Abstract Studies on the relationship between Handroanthus serratifolius and arbuscular mycorrhizal fungi (AMF) are limited in the literature. The influence of AMF spore density on plant development is fundamental information to determining the degree of benefits in this relationship. Therefore, the objective of this study was to investigate the effects

The Beneficial Role of Natural Endocrine Disruptors: Phytoestrogens in Alzheimer’s Disease

Oxidative Medicine and Cellular Longevity, Volume 2021, Issue 1, 2021., 2021
Alzheimer’s disease (AD) is the most common form of dementia with a growing incidence rate primarily among the elderly. It is a neurodegenerative, progressive disorder leading to significant cognitive loss. Despite numerous pieces of research, no cure for halting the disease has been discovered yet.

The Flavonoid Agathisflavone from Poincianella pyramidalis Prevents Aminochrome Neurotoxicity

Neurotoxicity Research, 2020
Flavonoids have been suggested to protect dopaminergic neurons in Parkinson's disease based on studies that used exogenous neurotoxins. In this study, we tested the protective ability of agathisflavone in SH-SY5Y cells exposed to the endogenous neurotoxin aminochrome.
