The miR319/bHLH094 Module Regulates Creeping Bentgrass Thermotolerance by Modulating Auxin Biosynthesis and Signalling Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT MicroRNA319 (miR319) has been demonstrated to regulate plant development and responses to stress such as drought and salt. However, its role in thermotolerance, particularly in cool season grasses, remains unclear. Here we report that miR319 plays a negative role in heat tolerance of creeping bentgrass (Agrostis stolonifera).

Transcription Profiling of Potato Leaves in Response to Heat Stress at Single‐Cell Resolution

Plant Biotechnology Journal, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) is a globally important food crop with considerable nutritional and economic value. Heat stress significantly inhibits potato plant growth and tuber development, constraining the sustainable development of the potato industry. Currently, studies on the cellular‐level mechanisms underlying heat adaptation in potato

Light-induced structural changes in a monomeric bacteriophytochrome

Structural Dynamics, 2016
Phytochromes sense red light in plants and various microorganism. Light absorption causes structural changes within the protein, which alter its biochemical activity.

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 ...

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.

A Hierarchical VvbHLH30‐VvERF70‐VvACS2 Module Orchestrates Ethylene Biosynthesis and Cold Adaptation in Grapevine

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.

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
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

Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Time‐ and space‐resolved transcriptional regulation in Arabidopsis thaliana

Plant Biology, EarlyView.
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.
