Plants might not feel pain as such, but they need a way to get damage signals around their body. A new study uncovers some of the process.

Resistance to the herbicide 2,4-D is complex in wild radish
Resistance to 2,4-D in wild radish is complex and appears to vary in its mechanism from one population to the next, but new research suggests that lower receptivity at the plasma membrane is part of the answer.

Hormone-metabolic interactions in adventitious roots
Adventitious roots are roots that form after the plant embryo has grown. They’re the roots that can grow out of stems when you make plant cuttings. Adventitious root formation is a bottleneck for the survival of...

Synthetic auxin resistance in wild radish is still an enigma
Guest author Danica Goggin finds wild radish is a problem weed in many agricultural regions. It is also very good at concealing its herbicide resistance strategies from inquisitive researchers. But with the introduction...

It’s the taste of flesh* that makes a Sundew salivate**
If you want to get a Sundew to feed on its prey, it has to do more than just wriggle.

Dual role of reactive oxygen species in seed physiology (Review)
Reactive oxygen species (ROS) are considered to be detrimental to seed viability. However, recent studies have demonstrated that ROS have key roles in seed germination particularly in the release of seed dormancy and...

Organelle-originated ROS and endoplasmic reticulum responses
Ozgur et al. induce the formation of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes of Arabidopsis thaliana and find that relatively low concentrations of ROS are more effective for...
Peroxisomes and regulation of ROS/RNS signalling (Review)
Sandalio and Romero-Puertas review the metabolism of reactive oxygen and nitrogen species (ROS and RNS) in peroxisomes and their contribution to the regulation of plant development and acclimation to stress conditions.
“Roger that!” Do plants have sound perception skills?
A wide range of abilities have long been attributed to the animals (within pluricellular organisms of the living world) to animals only: the ability to move, to stimulate an organ repetitively and very quickly, to...

Mastoparan-induced programmed cell death in Chlamydomonas
Under stress-promoting conditions unicellular algae can undergo programmed cell death (PCD), but the mechanisms are poorly understood. Yordanova et al. expose Chlamydomonas reinhardtii to the G-protein activator...
Molecular control of legume nodulation (Botanical Briefing)
Legume plants enter into symbiotic relationships with soil bacteria in order to obtain nitrogen to sustain plant growth. The nodulation associated with this is regulated in response to both internal developmental...
SI-mediated actin alterations in pollen (Review)
Self-incompatibility (SI) is generally controlled by the S-locus, and comprises allelic pollen and pistil S-determinants. Poulter et al. review and discuss our current understanding of the cytoskeletal alterations...
Networks, systems biology and data analysis
In my research, I always seem to be somewhere near the extremes of having too much data or not having enough data to address the questions I am asking. Even in experimental design, there seems to be a similar...

Microarray-analysis for components of salinity-stress tolerance
Microarray-analysis for components of salinity-stress tolerance Thiourea has been demonstrated to impart salinity-stress tolerance to seedlings of mustard, Brassica juncea. Srivastava et al. perform a genome-wide...
