Plants align flowering with optimal seasonal conditions to increase reproductive success. This process depends on modulating signalling pathways that respond to diverse environmental and hormonal inputs, thereby regulating the transition to flowering at the shoot apical meristem. In Arabidopsis, long-day photoperiods (LDs) stimulate the transcripti...

Apocarotenoids are ancient signaling molecules that have played crucial roles in biological communication and adaptation across evolutionary history. Originating in cyanobacteria, these molecules have diversified significantly in plants, where they contribute to stress perception, developmental regulation, and environmental responses. While some ap...

We describe transcriptional dynamics at the rice shoot apex by integrating time resolved single nuclei RNA-seq with bulk RNA-seq data. In rice, short days trigger floral transition and the transcriptional reprogramming of the shoot apex to become reproductive. We integrated time-resolved bulk RNA-seq with single nuclei RNA-seq analysis to gain a re...

Strigolactones are a class of phytohormones with various functions in plant development, stress responses, and in the interaction with (micro)organisms in the rhizosphere. While their effects on vegetative development are well studied, little is known about their role in reproduction. We investigated the effects of genetic and chemical modification...

The phytohormones strigolactones crosstalk with abscisic acid (ABA) in acclimation to osmotic stress, as ascertained in leaves. However, our knowledge about underground tissues is limited, and null in Arabidopsis. Namely, if strigolactones affect ABA transport across plasma membranes has never been addressed. We evaluated the effect of strigolacton...

The floral transition occurs at the shoot apical meristem (SAM) in response to favourable external and internal signals. Among these signals, variations in daylength (photoperiod) act as robust seasonal cues to activate flowering. In Arabidopsis, long-day photoperiods stimulate production in the leaf vasculature of a systemic florigenic signal that...

Water deficit conditions trigger the production of a chemical signal, the phytohormone abscisic acid (ABA), which coordinates multiple responses at different temporal and spatial scales. Despite the complexity of natural drought conditions, the modulation of ABA signaling could be harnessed to ameliorate the drought performances of crops in the fac...

Strigolactones (SLs) are carotenoid-derived phytohormones governing a wide range of physiological processes, including drought-associated stomatal closure. We have previously shown in tomato that SLs regulate the so-called after-effect of drought, whereby stomatal conductance is not completely restored for some time during recovery after a drought...

The convenient model Arabidopsis thaliana has allowed tremendous advances in plant genetics and physiology, in spite of only being a weed. It has also unveiled the main molecular networks governing, among others, abiotic stress responses. Through the use of the latest genomic tools, Arabidopsis research is nowadays being translated to agronomically...

Il report seguente simula gli indicatori relativi alla produzione scientifica in relazione alle soglie ASN 2018-2020 del proprio SC/SSD. Si ricorda che il superamento dei valori soglia (almeno 2 su 3) è requisito necessario ma non sufficiente al conseguimento dell'abilitazione. La simulazione si basa sui dati IRIS e presenta gli indicatori calcolat...

After quickly touching upon general aspects of strigolactones biology and functions, including structure, synthesis and perception, this review focuses on the role and regulation of the strigolactone pathway during osmotic stress, in light of the most recent research developments. We discuss available data on organ-specific dynamics of strigolacton...
