Physicochemical modeling of the phytochrome-mediated photothermal sensing
Scientific Reports, 2019 Light and temperature cues share many common signaling events towards plant photothermal morphogenesis. Particularly, the red (R)/far-red (FR)-absorbing phytochrome photoreceptors also function as temperature sensors, suggesting that light and ...

SlMYB17 Antagonises the SlCBF Pathway to Negatively Regulate Tomato Chilling Tolerance
Plant Biotechnology Journal, Volume 24, Issue 6, Page 4378-4392, June 2026.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, Volume 24, Issue 6, Page 4317-4341, June 2026.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.

Evidence that phytochrome functions as a protein kinase in plant light signalling
Nature Communications, 2016 Phytochromes regulate plant responses to environmental light conditions but despite extensive research the initial events in phytochrome signaling remain uncertain. Here, Shin et al.

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize
Plant Biotechnology Journal, Volume 24, Issue 6, Page 4415-4432, June 2026.ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Time‐ and space‐resolved transcriptional regulation in Arabidopsis thaliana
Plant Biology, Volume 28, Issue 4, Page 1005-1015, June 2026.Transcript abundance patterns in time and space of kinases, E3 ligases and transcription factors in Arabidopsis thaliana demonstrate ample room for dynamic and specific regulation of metabolism and stress responses. Abstract General metabolism and responses to internal or external signals are tightly regulated in plants.

Frontiers in Plant Science, 2014 Light perception by photoreceptors impacts plastid transcription, development, and differentiation. This photoreceptor-dependent activity suggests a mechanism for photoregulation of gene expression in the nucleus and plastid that serves to coordinate ...

Transcription of photosynthetic genes in the plant chloroplast: lessons from bacteria
The Plant Journal, Volume 126, Issue 5, June 2026.SUMMARY The RNA polymerase that transcribes photosynthetic genes in the plant chloroplast is the largest known transcription enzyme across all domains of life, comprising 21 subunits of bacterial and eukaryotic origin. Recent structural analyses revealed that the core polymerase, inherited from the cyanobacterial ancestor of the chloroplast, is encased
