Does oxygen affect ageing mechanisms of Pinus densiflora seeds? A matter of cytoplasmic physical state

D Gerna, D Ballesteros, E Arc, W Stöggl… - Journal of …, 2022 - academic.oup.com
During desiccation, the cytoplasm of orthodox seeds solidifies into an intracellular glass with
highly restricted diffusion and molecular mobility. Temperature and water content govern …

[PDF][PDF] Redox feedback regulation of ANAC089 signaling alters seed germination and stress response

…, E Nambara, M Godoy, JM Franco, R Solano, D Gerna… - Cell Reports, 2021 - cell.com
The interplay between the phytohormone abscisic acid (ABA) and the gasotransmitter nitric

Tailored media are key to unlocking the diversity of endophytic bacteria in distinct compartments of germinating seeds

D Gerna, D Clara, D Allwardt, B Mitter… - Microbiology …, 2022 - Am Soc Microbiol
Seeds offer an internal microbial niche, termed the endosphere, colonized by communities of
endophytic bacteria. To elucidate the functions of seed endophytes during germination and …

Hydrogen peroxide metabolism in interkingdom interaction between bacteria and wheat seeds and seedlings

D Gerna, T Roach, B Mitter, W Stöggl… - Molecular plant …, 2020 - Am Phytopath Society
In endophytes, the abundance of genes coding for enzymes processing reactive oxygen
species (ROS), including hydrogen peroxide (H 2 O 2 ), argues for a crucial role of ROS …

Redox poise and metabolite changes in bread wheat seeds are advanced by priming with hot steam

D Gerna, T Roach, E Arc, W Stöggl… - Biochemical …, 2018 - portlandpress.com
Fast and uniform germination is key to agricultural production and can be achieved by seed ‘priming’
techniques. Here, we characterised the responses of bread wheat (Triticum …

Changes in low-molecular-weight thiol-disulphide redox couples are part of bread wheat seed germination and early seedling growth

D Gerna, T Roach, W Stöggl, J Wagner… - Free Radical …, 2017 - Taylor & Francis
The tripeptide antioxidant glutathione (γ-l-glutamyl-l-cysteinyl-glycine; GSH) essentially
contributes to thiol-disulphide conversions, which are involved in the control of seed development…
