In all eukaryotes, the response to heat stress (HS) is dependent on the activity of HS transcription factors (Hsfs). Plants contain a large number of Hsfs, however, only members of the HsfA1 subfamily are considered as master regulators of stress response and thermotolerance. In Solanum lycopersicum, among the four HsfA1 members, only HsfA1a has been proposed to possess a master regulator function. We performed a comparative analysis of HsfA1a, HsfA1b, HsfA1c and HsfA1e at different levels of regulation and function. HsfA1a is constitutively expressed under control and stress conditions, while the other members are induced in specific tissues and stages of HS response. Despite that all members are localized in the nucleus when expressed in protoplasts, only HsfA1a shows a wide range of basal activity on several HS-induced genes. In contrast, HsfA1b, HsfA1c, and HsfA1e show only high activity for specific subsets of genes. Domain swapping mutants between HsfA1a and HsfA1c revealed that the variation in that transcriptional transactivation activity is due to differences in the DNA binding domain (DBD). Specifically, we identified a conserved arginine (R107) residue in the turn of β3 and β4 sheet in the C-terminus of the DBD of HsfA1a that is highly conserved in plant HsfA1 proteins, but is replaced by leucine and cysteine in tomato HsfA1c and HsfA1e, respectively. Although not directly involved in DNA interaction, R107 contributes to DNA binding and consequently the activity of HsfA1a. Thus, we demonstrate that this variation in DBD in part explains the functional diversification of tomato HsfA1 members.

Different genes coding for one ribosome biogenesis factor are differentially expressed and are likely under the control of distinct transcription factors, which contributes to the regulatory space for ribosome maturation. Maturation of ribosomes including rRNA processing and modification, rRNA folding and ribosome protein association requires the function of many ribosome biogenesis factors (RBFs). Recent studies document plant-specific variations of the generally conserved process of ribosome biogenesis. For instance, distinct rRNA maturation pathways and intermediates have been identified, the existence of plant specific RBFs has been proposed and several RBFs are encoded by multiple genes. The latter in combination with the discussed ribosome heterogeneity points to a possible function of the different proteins representing one RBF in diversification of ribosomal compositions. Such factor-based regulation would require a differential regulation of their expression, may be even controlled by different transcription factors. We analyzed the expression profiles of genes coding for putative RBFs and transcription factors. Most of the genes coding for RBFs are expressed in a comparable manner, while different genes coding for a single RBF are often differentially expressed. Based on a selected set of genes we document a function of the transcription factors AtMYC1, AtMYC2, AtbHLH105 and AtMYB26 on the regulation of different RBFs. Moreover, on the example of the RBFs LSG1 and BRX1, both encoded by two genes, we give a first hint on a differential transcription factor dependence of expression. Consistent with this observation, the phenotypic analysis of RBF mutants suggests a relation between LSG1-1 and BRX1-1 expression and the transcription factor MYC1. In summary, we propose that the multiple genes coding for one RBF are required to enlarge the regulatory space for ribosome biogenesis.

Regulation of two GTPases Toc159 and Toc34 in the translocon of the outer envelope of chloroplasts

The GTPases Toc159 and Toc34 of the translocon of the outer envelope of chloroplasts (TOC) are involved in recognition and transfer of precursor proteins at the cytosolic face of the organelle. Both proteins engage multiple interactions within the translocon during the translocation process, including dimeric states of their G-domains. The units of the Toc34 homodimer are involved in the recognition of the transit peptide representing the translocation signal of precursor proteins. This substrate recognition is part of the regulation of the GTPase cycle of Toc34. The Toc159 monomer and the Toc34 homodimer recognize the transit peptide of the small subunit of Rubisco at the N- and at the C-terminal region, respectively. Analysis of the transit peptide interaction by crosslinking shows that the heterodimer between both G-domains binds pSSU most efficiently. While substrate recognition by Toc34 homodimer was shown to regulate nucleotide exchange, we provide evidence that the high activation energy of the GTPase Toc159 is lowered by substrate recognition. The nucleotide affinity of Toc34G homodimer and Toc159G monomer are distinct, Toc34G homodimer recognizes GDP and Toc159G GTP with highest affinity. Moreover, the analysis of the nucleotide association rates of the monomeric and dimeric receptor units suggests that the heterodimer has an arrangement distinct from the homodimer of Toc34. Based on the biochemical parameters determined we propose a model for the order of events at the cytosolic side of TOC. The molecular processes described by this hypothesis range from transit peptide recognition to perception of the substrate by the translocation channel.
