An improved strategy to analyse strigolactones in complex sample matrices using UHPLC–MS/MS

Plant Methods, 2020
Background Strigolactones represent the most recently described group of plant hormones involved in many aspects of plant growth regulation. Simultaneously, root exuded strigolactones mediate rhizosphere signaling towards beneficial arbuscular ...

Dual Role of Gibberellin in Perennial Shoot Branching: Inhibition and Activation

Frontiers in Plant Science, 2020
Shoot branching from axillary buds (AXBs) is regulated by a network of inhibitory and promotive forces, which includes hormones. In perennials, the dwarfed stature of the embryonic shoot inside AXBs is indicative of gibberellin (GA) deficiency ...

The Cytokinin Status of the Epidermis Regulates Aspects of Vegetative and Reproductive Development in Arabidopsis thaliana

Frontiers in Plant Science, 2021
The epidermal cell layer of plants has important functions in regulating plant growth and development. We have studied the impact of an altered epidermal cytokinin metabolism on Arabidopsis shoot development.

Cell-surface receptors enable perception of extracellular cytokinins

Nature Communications, 2020
The main site of cytokinin perception in plant cells is thought to be the endoplasmic reticulum where most cytokinin receptors localise. Here via the use of bioactive probes that cannot enter plant cells and super-resolution microscopy, Antoniadi et al ...
