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 ...

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.

Phytochrome A Protects Tomato Plants From Injuries Induced by Continuous Light

Frontiers in Plant Science, 2019
Plants perceive and transduce information about light quantity, quality, direction and photoperiod via several photoreceptors and use it to adjust their growth and development.

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.

The role of the seed coat in the light sensivity in Raphanus sativus L. cv. redondo gigante seeds O papel do tegumento na sensibilidade à luz em sementes de Raphanus sativus L. cv. redondo gigante

Acta Botânica Brasílica, 1997
The role of the seed coat in the light sensitivity of seeds of Raphanus sativus L. cv. redondo gigante was analysed by germination tests of intact and naked seeds. Far-red light caused high inhibition of seed germination, while under white and red lights

The short-lived MATα2 transcriptional regulator is ubiquitinated in vivo [PDF]

, 1991
The substrates of ubiquitin-dependent proteolytic pathways include both damaged or otherwise abnormal proteins and undamaged proteins that are naturally short-lived. Few specific examples of the latter class have been identified, however.

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.

Effects of Light and Wounding on Jasmonates in Rice phyAphyC Mutants

Plants, 2014
Jasmonates (JA) are lipid-derived plant hormones. They have been shown to be important regulators of photomorphogenesis, a developmental program in plants, which is activated by light through different red and blue light sensitive photoreceptors. In rice,

Large-effect flowering time mutations reveal conditionally adaptive paths through fitness landscapes in Arabidopsis thaliana. [PDF]

, 2019
Contrary to previous assumptions that most mutations are deleterious, there is increasing evidence for persistence of large-effect mutations in natural populations.
