How does it feel?
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.

A class of chemicals that produce many of the colours of petals also regulates root response in White Lupins
Flavonoids help fine-tune a lupin's response to low phosphorus availability.
Wounds divert auxin flow like “rocks in a stream”
The hormone auxin confers stem cell identity on cells surrounding the wound to enable healing.

Understanding the connections between plant hormones and cellulose synthesis in plants: still a great unknown!
Wang and colleagues review the relationships between key phytohormone classes and cellulose deposition in plant systems.

New insights on the role of cytokinin in nodule formation
Cytokinins may have a role in controlling both bacterial accommodation and tissue differentiation related to nodule formation.
Auxin redistribution modifies maize root proliferation
We know that maize roots chase after phosphorus, but how? Xin Wang and colleagues have been investigating what purpose the hormone auxin has in controlling root proliferation. Their work could help better understand how...

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.
Strigolactones interact with other plant hormones in many situations
Strigolactones are interesting phytohormones in their own right, but Luke Omoarelojie and colleagues say we should be looking at cross-talk with other hormones too.
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...

Potential involvement of root auxins in drought tolerance by modulating nocturnal and daytime water use in wheat
The ability of wheat genotypes to save water by reducing their transpiration rate (TR) at times of the day with high vapour pressure deficit (VPD) has been linked to increasing yields in terminal drought environments...
Auxin transport and stem vascular reconnection – has our thinking become canalized?
The presence of a polar auxin transport stream has long been correlated with the differentiation and patterning of vascular cells across vascular plants. As our understanding of auxin transport and vascular development...
Abscisic acid inhibits hypocotyl elongation acting on gibberellins, DELLA proteins and auxin
Hypocotyl elongation of Arabidopsis seedlings is influenced by light and numerous growth factors. Light inhibits hypocotyl elongation (photomorphogenesis), whereas elongation is promoted in the dark (skotomorphogenesis)...

Subsidiary cell formation in Poaceae stomatal complexes
Polarisation and asymmetrical division generating the Poaceous subsidiary cells constitutes a very attractive model for the study of local intercellular stimulation. Auxin operates as an inductive stimulus while PIN...
