Major improvements in crop yield are needed to keep pace with population growth and
climate change. While plant breeding efforts have greatly benefited from advances in …

In order to optimally establish their root systems, plants are endowed with several
mechanisms to use at distinct steps during their development. In this review, we zoom in on …

Auxin is a major phytohormone that controls numerous aspects of plant development and
coordinates plant responses to the environment. Morphogenic gradients of auxin govern cell …

Auxin regulates a vast array of growth and developmental processes throughout the life
cycle of plants. Auxin responses are highly context dependent and can involve changes in …

During plant growth, dividing cells in meristems must coordinate transitions from division to
expansion and differentiation, thus generating three distinct developmental zones: the …

The architecture of the branched root system of plants is a major determinant of vigor. Water
availability is known to impact root physiology and growth; however, the spatial scale at …

In multicellular organisms, a stringent control of the transition between cell division and
differentiation is crucial for correct tissue and organ development. In the Arabidopsis root …

Tropisms, growth responses to environmental stimuli such as light or gravity, are spectacular
examples of adaptive plant development. The plant hormone auxin serves as a major …

Plants are equipped with the capacity to respond to a large number of diverse signals, both
internal ones and those emanating from the environment, that are critical to their survival …

In this review, we summarize the different biosynthesis-related pathways that contribute to
the regulation of endogenous auxin in plants. We demonstrate that all known genes …
