Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae
New Phytologist, EarlyView.Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

New Phytologist, EarlyView.Cytokinin–phyB signaling modulates PSII photochemistry during prolonged darkness. Summary Cytokinins (CKs) delay dark‐induced senescence, but how they tune photosynthetic function in darkness remains unclear. We investigated the effects of classical aromatic CK benzylaminopurine and CK‐derived compound 1‐(2‐methoxyethyl)‐3‐(1,2,3‐thiadiazol‐5‐yl)urea ...

SlMYB17 Antagonises the SlCBF Pathway to Negatively Regulate Tomato Chilling Tolerance
Plant Biotechnology Journal, EarlyView.ABSTRACT Low temperature is a significant environmental constraint, impeding the extensive cultivation of tropical plants. Here, we identify the transcription factor SlMYB17 as an important negative regulator of tomato chilling tolerance. Overexpression of SlMYB17 significantly reduced chilling tolerance, whereas slmyb17 mutants exhibited enhanced ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Ethylene is a key gaseous phytohormone that plays crucial roles in regulating plant growth, development and stress responses. However, ethylene‐associated biosynthetic and transcriptional regulatory mechanisms governing cold‐adaptation responses in plants remain poorly understood.

Phytochrome A Regulates Carbon Flux in Dark Grown Tomato Seedlings
Frontiers in Plant Science, 2019 Phytochromes comprise a small family of photoreceptors with which plants gather environmental information that they use to make developmental decisions, from germination to photomorphogenesis to fruit development.
