The Cys-Arg/N-end rule pathway is a general sensor of abiotic stress in flowering plants (2017)
Journal Article

Abiotic stresses impact negatively on plant growth, profoundly affecting yield and quality of crops. Although much is known about plant responses, very little is understood at the molecular level about the initial sensing of environmental stress. In...

First hints of new sensors (2017)
Journal Article

A mechanism by which plants detect and respond to oxygen starvation has been known for some years. Three recent papers suggest that we haven’t been seeing the full picture.

Community recommendations on terminology and procedures used in flooding and low oxygen stress research (2017)
Journal Article

Apart from playing a key role in important biochemical reactions, molecular oxygen (O2) and its by-products also have crucial signaling roles in shaping plant developmental programs and environmental responses. Even under normal conditions, sharp O2... Read More about Community recommendations on terminology and procedures used in flooding and low oxygen stress research.

Hypoxia response in Arabidopsis roots infected by Plasmodiophora brassicae supports the development of clubroot (2016)
Journal Article

Background The induction of alcohol fermentation in roots is a plant adaptive response to flooding stress and oxygen deprivation. Available transcriptomic data suggest that fermentation-related genes are also frequently induced in roots infected w...

Dormant and after-ripened Arabidopsis thaliana seeds are distinguished by early transcriptional differences in the imbibed state (2016)
Journal Article

Seed dormancy is a genetically controlled block preventing the germination of imbibed seeds in favorable conditions. It requires a period of dry storage (after-ripening) or certain environmental conditions to be overcome. Dormancy is an important see... Read More about Dormant and after-ripened Arabidopsis thaliana seeds are distinguished by early transcriptional differences in the imbibed state.

From start to finish: amino-terminal protein modifications as degradation signals in plants (2016)
Journal Article

The amino- (N-) terminus (Nt) of a protein can undergo a diverse array of co- and posttranslational modifications. Many of these create degradation signals (N-degrons) that mediate protein destruction via the N-end rule pathway of ubiquitin-mediated...

The wheat Phs-A1 pre-harvest sprouting resistance locus delays the rate of seed dormancy loss and maps 0.3 cM distal to the PM19 genes in UK germplasm (2016)
Journal Article

The precocious germination of cereal grains before harvest, also known as pre-harvest sprouting, is an important source of yield and quality loss in cereal production. Pre-harvest sprouting is a complex grain defect and is becoming an increasing chal...

Oxygen Sensing Coordinates Photomorphogenesis to Facilitate Seedling Survival (2015)
Journal Article

Successful emergence from the soil is essential for plant establishment in natural and farmed systems. It has been assumed that the absence of light in the soil is the preeminent signal perceived during early seedling development, leading to a distin...

Group VII ethylene response factors coordinate oxygen and nitric oxide signal transduction and stress responses in plants (2015)
Journal Article

The group VII ethylene response factors (ERFVIIs) are plant-specific transcription factors that have emerged as important regulators of abiotic and biotic stress responses, in particular, low-oxygen stress. A defining feature of ERFVIIs is their cons... Read More about Group VII ethylene response factors coordinate oxygen and nitric oxide signal transduction and stress responses in plants.

Multi-omics analysis identifies genes mediating the extension of cell walls in the Arabidopsis thaliana root elongation zone (2015)
Journal Article

Plant cell wall composition is important for regulating growth rates, especially in roots. However, neither analyses of cell wall composition nor transcriptomes on their own can comprehensively reveal which genes and processes are mediating growth an...

Enhanced waterlogging tolerance in barley by manipulation of expression of the N-end rule pathway E3 ligase PROTEOLYSIS6 (2015)
Journal Article

© 2016 Society for Experimental Biology, Association of Applied Biologists and John Wiley & Sons Ltd. Increased tolerance of crops to low oxygen (hypoxia) during flooding is a key target for food security. In Arabidopsis thaliana (L.) Heynh., the N...

Promotion of testa rupture during garden cress germination involves seed compartment-specific expression and activity of pectin methylesterases (2015)
Journal Article

Pectin methylesterase (PME) controls the methylesterification status of pectins and thereby determines the biophysical properties of plant cell walls, which are important for tissue growth and weakening processes. We demonstrate here that tissue-spec...

Large-scale identification of gibberellin-related transcription factors defines Group VII ERFs as functional DELLA partners (2014)
Journal Article

Barley has two peroxisomal ABC transporters with multiple functions in ?-oxidation (2014)
Journal Article

In oilseed plants, peroxisomal ?-oxidation functions not only in lipid catabolism but also in jasmonate biosynthesis and metabolism of pro-auxins. Subfamily D ATP-binding cassette (ABC) transporters mediate import of ?-oxidation substrates into the p...

Mechanical constraints imposed by 3D cellular geometry and arrangement modulate growth patterns in the Arabidopsis embryo (2014)
Journal Article

Morphogenesis occurs in 3D space over time and is guided by coordinated gene expression programs. Here we use postembryonic development in Arabidopsis plants to investigate the genetic control of growth. We demonstrate that gene expression driving th...

Nitric oxide sensing in plants is mediated by proteolytic control of Group VII ERF transcription factors (2014)
Journal Article

Nitric oxide (NO) is an important signaling compound in prokaryotes and eukaryotes. In plants, NO regulates critical developmental transitions and stress responses. Here, we identify a mechanism for NO sensing that coordinates responses throughout de...

Homeostatic response to hypoxia is regulated by the N-end rule pathway in plants (2011)
Journal Article

Plants and animals are obligate aerobes, requiring oxygen for mitochondrial respiration and energy production. In plants, an unanticipated decline in oxygen availability (hypoxia), as caused by roots becoming waterlogged or foliage submergence, trigg...
