Poplar trees use photoperiod as a precise seasonal indicator, synchronizing plant phenology with the environment. Daylength cue determines FLOWERING LOCUS T 2 (FT2) daily expression, crucial for shoot apex development and establishment of the annual growing period. However, limited evidence exists for the molecular factors controlling FT2 transcription and the conservation with the photoperiodic control of Arabidopsis flowering.

- The study focuses on understanding how stem cells in the shoot apex of woody plants like Populus develop into different tissues and organs, specifically examining the lack of a lineage map for these cells.
- Using single-nuclei RNA-sequencing, researchers identified seven major cell populations and established developmental pathways for various tissues, including epidermis, leaf mesophyll, and vascular tissue.
- By comparing the vascular development between Populus and the model plant Arabidopsis, the study highlights similarities and differences in cell differentiation processes across species, providing insights for future research on plant biology.
The detection of oxidative stress caused by emerging pollutants in aquatic systems is essential to carry out toxicological analysis since they can bring us information about the mechanisms of toxic action of the pollutants, which might be useful to address this contamination. To achieve this goal, two self-bioluminescent strains that respond to oxidative stress based on the filamentous cyanobacterium Nostoc sp. PCC7120, which has a high ecological relevance in aquatic continental systems, have been constructed.
