Light and temperature signals are integrated through a phyB-dependent gene regulatory network in rice.

Angiosperms are the most dominant land plant flora and have colonised most of the terrestrial habitats, thriving in different environmental conditions, among which light and temperature play a crucial role. In the eudicot Arabidopsis thaliana, light and temperature are integrated into a phytochrome B (phyB)-dependent signalling network that regulates development. However, whether this signal integration controls the development in other angiosperm lineages and if phyB is a conserved hub of this integratory network in angiosperms is unclear.

Endless forms most frustrating: disentangling species boundaries in the group (), with the description of six new species and a key to the group.

Oceanic islands have been recognized as natural laboratories in which to study a great variety of evolutionary processes. One such process is evolutionary radiations, the diversification of a single ancestor into a number of species that inhabit different environments and differ in the traits that allow them to exploit those environments. The factors that drive evolutionary radiations have been studied for decades in charismatic organisms such as birds or lizards, but are lacking in lichen-forming fungi, despite recent reports of some lineages showing diversification patterns congruent with radiation.

Exploring the Phytochemical Composition and the Bioactive Properties of Malbec and Torrontés Wine Pomaces from the Calchaquíes Valleys (Argentina) for Their Sustainable Exploitation.

Hydroalcoholic extracts from Malbec and Torrontés wine pomaces ( L.) originating from the high-altitude vineyards of Argentina's Calchaquí Valleys were characterized. Total phenolics, hydroxycinnamic acids, orthodiphenols, anthocyanins, non-flavonoid phenolics, total flavonoids, flavones/flavonols, flavanones/dihydroflavonols, and tannins were quantified through spectrophotometric methods, with the Malbec extract exhibiting higher concentrations in most of phytochemical groups when compared to Torrontés.

Charting the evolutionary path of the SUMO modification system in plants reveals molecular hardwiring of development to stress adaptation.

SUMO modification is part of the spectrum of Ubiquitin-like (UBL) systems that give rise to proteoform complexity through post-translational modifications (PTMs). Proteoforms are essential modifiers of cell signaling for plant adaptation to changing environments. Exploration of the evolutionary emergence of Ubiquitin-like (UBL) systems unveils their origin from prokaryotes, where it is linked to the mechanisms that enable sulfur uptake into biomolecules.
