Abstract Background Lateral root (LR) architecture determines the efficiency of nutrient absorption and anchors the plant. Internal auxin regulatory mechanisms that control the development of LR have been identified, but how external nutrients influence lateral root development remains elusive. Results We have characterized the functions of the FK506-binding proteins FKBP15-1 and FKBP15-2 in Arabidopsis. FKBP genes are mainly expressed in the vascular bundle of the root basal meristem region, and the FKBP proteins are localized to the endoplasmic reticulum. Co-IP and BIFC assays showed that FKBP15-1 and FKBP15-2 interact with the vacuolar invertase 2 (VIN2). Compared to Col-0 and the single mutants, the double mutant fkbp15-1fkbp15-2 had more LRs and LR initiation density, and possessed higher sucrose catalytic activity. Moreover, VIN2 can complement the phenotype of increased LRs in the fkbp15-1fkbp15-2 double mutant. Conclusion Our results indicate that FKBP15-1 and FKBP15-2 together participate in the control of LR numbers by regulating the enzyme activity of VIN2. Due to the activity of peptidylprolyl cis-trans isomerases owned by FKBP family proteins, our results provide a clue to further analysis the interplay between lateral root development and protein modification.

Lateral Root Development

Abstract Lateral roots are important to forage for nutrients due to their ability to increase the uptake area of a root system. Hence, it comes as no surprise that lateral root formation is affected by nutrients or nutrient starvation, and as such contributes to the root system plasticity. Understanding the molecular mechanisms regulating root adaptation dynamics towards nutrient availability is useful to optimize plant nutrient use efficiency. There is at present a profound, though still evolving, knowledge on lateral root pathways. Here, we aimed to review the intersection with nutrient signaling pathways to give an update on the regulation of lateral root development by nutrients, with a particular focus on nitrogen. Remarkably, it is for most nutrients not clear how lateral root formation is controlled. Only for nitrogen, one of the most dominant nutrients in the control of lateral root formation, the crosstalk with multiple key signals determining lateral root development is clearly shown. In this update, we first present a general overview of the current knowledge of how nutrients affect lateral root formation, followed by a deeper discussion on how nitrogen signaling pathways act on different lateral root-mediating mechanisms for which multiple recent studies yield insights.
