Improving crop tolerance to environmental stresses is of paramount importance to global food security. To protect themselves from abiotic stress, plants translate environmental inputs into internal signals through...

Actin cytoskeleton, plant growth and development in Arabidopsis root hair mutant der1-3
The DER1 (deformed root hairs1) locus encodes a major vegetative actin (ACTIN2) in Arabidopsis thaliana. Mutations in DER1 lead to impaired root hair development. However, the role of this gene in overall plant...

Cell cycle duration in the root apical meristem (RAM) of angiosperms
In plant studies it is essential to determine cell cycle duration (T). Zhukovskaya et al. have previously proposed an exponential model evaluating T in the root apical meristem (RAM) based on the dynamics of root...
Cress Kung-Fu
Cress seeds exude a nutrient for other plants into the soil, but is this a sneaky way of protecting the cress seedlings from competition?

From genes to networks: genetic control of root growth (Invited Review)
This review first describes the root system and then presents fundamental work that has shed light on the basic regulatory principles of root growth and development.

Auxin, thioredoxin reductase, denitrosylation and root growth
Auxin is the main phytohormone controlling root development in plants. Correa-Aragunde et al. grow seedlings of Arabidopsis thaliana treated with auxin with or without thioredoxin reductase (NTR) inhibitors and find...
Strigolactones and adventitious root formation in rice
Strigolactones (SLs) and their derivatives are plant hormones that have recently been identified as regulating root development. Sun et al. study adventious roots (ARs) in SL-deficient (d10) and SL-insensitive (d3)...
Enhancing the acid-soil tolerance of durum wheat
A fragment of the 4D chromosome containing TaALMT1, introgressed into an elite durum cultivar, shows that the fragment enhances root growth in acid soil.
Use it or lose it, for a plant’s sense of gravity?
Gravitropism is the ability of a plant to turn in response to gravity. Roots have gravitropism, bending to turn down and stems negative gravitropism to turn up. But what happens if you remove a plant’s ability to...
Don’t ignore the roots… or the soil!
Lab experiments are all well and good, but they do have their limitations. It is necessary to study plants outside, in the field – or rather below the surface! This theme was explored at the UKPSF conference by Nick...

Localized N supply inhibits auxin transport in roots
Localized N supply inhibits auxin transport in roots Roots typically respond to localized nitrate patch in soils by enhancing lateral root growth. Using maize, Zea mays, grown in a split-root system, Liu et al...
