We present here an innovative design of hydroponic rhizotrons (rhizoponics) adapted to Arabidopsis thaliana. The setup allows to simultaneously characterize the RSA and shoot development from seedling to adult stages, i.e. from seed to seed. This system offers the advantages of hydroponics such as control of root environment and easy access to the roots for measurements or sampling. Being completely movable and low cost, it can be used in controlled cabinets. We chose the case of cadmium treatment to illustrate potential applications, from cell to organ levels. [less ▲]

Roots are responsible for water and nutrient uptake and hence are critical to sustain the whole plant life cycle. This study aims at characterizing how root development is affected by flowering. We therefore focused on the effects of systemic signals produced in the leaves at floral transition, namely the proteins FLOWERING LOCUS T (FT) and TWIN SISTER OF FT (TSF), on root growth and branching. These proteins act in the shoot apical meristem as potent promoters of flowering [1] but their effects in other parts of the plant are still unknown. [less ▲]

Flowering in Arabidopsis thaliana is controlled by photoperiod. In long days, the mobile proteins FLOWERING LOCUS T (FT) and TWIN SISTER OF FT (TSF) are produced in the leaves and transported in the phloem toward the shoot apical meristem (SAM). In the SAM, FT and TSF interact with the transcription factor FD to activate the expression of genes responsible for floral meristem identity [1]. Since the formation of flowers and fruits is a costly and critical stage for the plant, it is expected to be supported by a well developed root system to insure the increase in plant’s needs. As a first step to understand the effects of flowering on root growth, we compared root development in long days, promoting flowering, and in short days (16h and 8h days, respectively). [less ▲]
