Match Algorithms for Scientific Names in FlorItaly, the Portal to the Flora of Italy

open access: yesPlants, 2021
Scientific names are not part of everyday language in any modern country, and their input as strings in a query system can be easily associated with typographical errors.

Neoteny of the European plane tree [PDF]

open access: yesArchives of Biological Sciences, 2012
The neoteny of 64-day-old European plane tree autovegetative progeny is described, starting from the fact that sexual maturity in the juvenile stage of tree development is a rare and significant process by which the period of synthesis of new lower ...

On a Non-Discrete Concept of Prokaryotic Species

open access: yesMicroorganisms, 2020
The taxonomic concept of species has received continuous attention. A microbial species as a discrete box contains a limited number of highly similar microorganisms assigned to that taxon, following a polyphasic approach.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
