Description
Translation elongation in Arabidopsis thaliana was studied using ribosome profiling. 3 biological replicates of young, immature leaves of Arabidopsis thaliana, Col-0, grown in short day conditions for 7 weeks were harvested. Ribosomal footprints were produced by digestion with MNase, the ribosomes were purified by centrifugation through a sucrose cushion and the RNA was isolated from the ribosome fraction. The 16-42 nt fraction was sequenced using Illumina’s HiSeq 4000.

Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
In depth temporal profiling of transcript changes at 10 time points during germination in Arabidopsis seed was carried out. The time course utilised, encompassed seed maturation, stratification, germination and post-germination and provided a global investigation into the tightly regulated, phasic changes that define seed germination.

Description
Transcriptomic analysis of gene expression during the differentiation of cell suspension cultures into tracheary elements using the biological system published by Pesquet et al., Current Biology (2010): tracheary element differentiation was triggered by externally supplying hormone-free habituated cell suspension cultures of Arabidopsis thaliana Col-0 with auxin, cytokinin and epibrassinolides; RNA samples extracted from 3 independent time-courses every 12h from 0h to 4 days were analyzed using ATH1 Arabidopsis Affymetrix micro-array

Description
Soil salinity increasingly causes crop losses worldwide. Although roots are the primary targets of salt stress, the signaling networks that facilitate metabolic reprogramming to induce stress tolerance are less understood than those in leaves. Here, a combination of transcriptomic and metabolic approaches was performed in salt-treated Arabidopsis thaliana roots, which revealed that the group S1 basic leucine zipper transcription factors bZIP1 and bZIP53 reprogram primary C- and N-metabolism. In particular, gluconeogenesis and amino acid catabolism are affected by these transcription factors. Importantly, bZIP1 expression reflects cellular stress and energy status in roots. In addition to the well-described abiotic stress response pathway initiated by the hormone abscisic acid (ABA) and executed by SnRK2 (Snf1-RELATED-PROTEIN-KINASE2) and AREB-like bZIP factors, we identify a structurally related ABA-independent signaling module consisting of SnRK1s and S1 bZIPs. Crosstalk between these signaling pathways recruits particular bZIP factor combinations to establish at least four distinct gene expression patterns. Understanding this signaling network provides a framework for securing future crop productivity.

Description
Sugars modulate expression of hundreds of genes in plants. Previous studies on sugar signaling, using intact plants or plant tissues, were hampered by tissue heterogeneity, uneven sugar transport and/or inter-conversions of the applied sugars. This, in turn, could obscure the identity of a specific sugar that acts as a signal affecting expression of given gene in a given tissue or cell-type. To bypass those biases, we have developed a novel biological system, based on stem-cell-like Arabidopsis suspension culture. The cells were grown in a hormone-free medium and were sustained on xylose as the only carbon source. The functional genomics approach was used to identify sugar responsive genes, which rapidly (within 1 h) respond specifically to low concentration (1 mM) of glucose, fructose and/or sucrose.
