Morphology of lateral root development (Invited Review)
doi:10.1093/aob/mct231
When exposed to physiological or mechanical stresses, roots show an extraordinary capacity to adapt by regulating growth rates, which are eventually manifested as morphogical responses. Szymanowska-Pułka (pp. 1643–1654) reviews various morphological aspects of lateral branching in roots, including events occurring during the formation of a lateral root and different types of defects that can occur in the morphology of primordia in both wild-type plants and mutants. Lateral root formation is also discussed in terms of mechanics, in which the primordium is considered as a physical object undergoing deformation, and characterized with specific mechanical properties.

Auxin, environmental signals and root development (Review)
doi:10.1093/aob/mct229
Significant progress is being made towards a full understanding of the roles played by auxin (IAA) in plant growth and development. Kazan (pp.1655–1665 ) reviews the role of IAA as an integrator of environmental signals, and highlights recent findings on how plants utilize IAA signalling and transport to modify their root system architecture when responding to diverse biotic (e.g. pathogenic and beneficial microbes and nematodes) and abiotic (salt, cold, moisture, acidity and soil nutrient status) rhizosphere signals. Understanding the molecular mechanisms involved in auxin–environment interactions can assist the development of crops better adapted to stressful environments.
