Project description:Plant roots located in the upper soil layers are prone to experience high temperatures. To gain insight into the effect of high temperature on root development and functioning, we exposed five-day-old Arabidopsis thaliana seedlings grown on agar plates to 30 °C for 48 hours, and compared the gene expression profile in the root tip with that from seedlings that remained at 22 °C.

Project description:Maintenance of the root-meristem is determined by polar auxin transport (PAT) and asymmetric cell division (ACD). We find that flavonoids scutellarin and scutellarein, which both have 6-hydroxyl group that differs in its structure from all known-flavonoid PAT inhibitors, promote PAT and ACD in Arabidopsis thaliana root tip, and increase root length. We used microarrays to detail the global programme of gene expression under scutellarin and mock (DMSO) treatment and identified distinct classes of genes regulated by scutellarin.

Project description:Cyanide is stoichiometrically produced as a co-product of the ethylene biosynthesis pathway, and it is detoxified by the b-cyanoalanine synthase enzyme. The molecular and phenotypical analysis of T-DNA insertional mutants of the mitochondrial b-cyanoalanine synthase CYS-C1 suggests that discrete accumulation of cyanide is not toxic for the plant and does not alter mitochondrial respiration rates, but does act as a strong inhibitor of root hair development. The cys-c1 null allele is defective in root hair formation and accumulates cyanide in root tissues. The root hair defect is phenocopied in wild type plants by the exogenous addition of cyanide to the growth medium and is reversed by the addition of hydroxocobalamin. Hydroxocobalamin not only recovers the root phenotype of the mutant, but also the formation of ROS at the initial step of the root hair tip. Transcriptional profile analysis of the cys-c1 mutant reveals that cyanide accumulation acts as a repressor signal for several genes encoding enzymes involved in cell wall rebuilding and the formation of the root hair tip, as well as genes involved in ethylene signaling and metabolism. Our results demonstrate that mitochondrial b-cyanoalanine synthase activity is essential to maintain a low level of cyanide for proper root hair development.

Project description:Previous transcript profiling of the Arabidopsis LRIS only occurred after 2 and 6 hours of NAA treatment (Himanen et al., 2004, Vanneste et al., 2005, De Smet et al., 2008). Here, we extended the time-course of the Arabidopsis LRIS to capture the expression during primordium formation. Therefore, we first characterized lateral root primordium development in the Arabidopsis LRIS, and performed staging in different regions of the root. We observed a slight loss of the synchronization in higher parts of the root. Nevertheless at 1 to 2 mm distance from the root tip, different stages of primordia were highly synchronously induced, and stage I, II and III primordia could be observed at 12, 18 and 24 hours after NAA treatment, respectively. We therefore sampled the 1 to 2 mm region from the root tip at 0, 12, 18 and 24 hours in the Arabidopsis LRIS, to sample stage I, II and III primordia, respectively.

Project description:Canonical auxin signalling starts with auxin binding to the receptor complex, followed by modulation of gene transcription and protein abundance (Tan et al., 2007; Chapman and Estelle, 2009; Slade et al., 2017). However, recent studies also showed an alternative mechanism in roots involving intra-cellular auxin perception, but not transcriptional reprogramming (Fendrych et al., 2018). Despite knowledge on effects of auxin on Arabidopsis root growth at the protein and phosphorylation level is increasing (Zhang et al., 2013; Mattei et al., 2013; Slade et al., 2017), it still remains incomplete. To address this gap in our knowledge, we explored the impact of auxin on the root tip proteome and phosphoproteome.
