Ribosome biogenesis is essential for cellular function and involves rRNA synthesis, rRNA processing and modification, and ribosomal protein assembly. Ribosome biogenesis factors and small nucleolar RNA assist these events. Ribosomal maturation takes place in the nucleolus, the nucleoplasm, and the cytosol in a coordinated and controlled manner. For example, some ribosomal proteins are thought to be assembled in the cytoplasm based on the observations in Saccharomyces cerevisiae. Here, we used cellular fractionation to demonstrate that cleavage of the 20S intermediate, the precursor to mature 18S rRNA, does not occur in the nucleoplasm of Arabidopsis thaliana. It most likely occurs in the cytoplasm. Further, we verified the proposed localization of RPS10e, RPS26e, and RPL24a/b in the nucleus and RPP1 in the nucleolus of A. thaliana by ribosome profiling, immunofluorescence, and analysis of the localization of GFP fusion proteins. Our results suggest that the order of events during ribosomal protein assembly in the ribosome biogenesis pathway differs between plants and yeast.

Conventional data transmission via cable or electromagnetic waves reaches their limits in harsh or hard-to-reach environments. For example in bore hole inspection, cables can break and electromagnetic waves cannot pass different earth layers. Actual studies showing that guided waves are a possible instrument for cable less data transmission. The known technique works with frequencies below 100 kHz for a wave propagating of long distances and known time delays. This concept limits the data transmission rate to e.g. 250 bit/s at a 2m long steel pipe. Other cable less developments are also known in so-called "wall to wall" communication by means of ultrasonic sound waves. Here, frequencies of 1 MHz are used to transmit data in the order of 550 bit/s through one wall with opposing transducers. In our approach we are using guided waves with a center frequency of 1 MHz. Furthermore a sweep mode is used instead of the pulse position modulation (PPM). Thus, it is possible to be independent of a known transmitter and receiver position and thereby the knowledge of the time delay. Thereby, in contrast to the already known technology it is possible to use a two-dimensional arbitrary surface for data communication. At a first experiment, a data transmission distance of 20 cm at a 3 mm glass plate was build. One single-phase transducer is used as transmitter and two different transducers as receiver to show the independence of position of the receiver. Wave reflections at the edges of the glass plate and dispersion of the guided wave could also be eliminated by the here used algorithm of identifying the biggest amplitude of the received signal. Thereby a transmission rate of 1,5 kBit/s with good SNR could be observed.

BACKGROUND: Pollen development is central for plant reproduction and is assisted by changes of the transcriptome and proteome. At the same time, pollen development and viability is largely sensitive to stress, particularly to elevated temperatures. The transcriptomic and proteomic changes during pollen development and of different stages in response to elevated temperature was targeted to define the underlying molecular principles. RESULTS: The analysis of the transcriptome and proteome of Solanum lycopersicum pollen at tetrad, post-meiotic and mature stage before and after heat stress yielded a decline of the transcriptome but an increase of the proteome size throughout pollen development. Comparison of the transcriptome and proteome led to the discovery of two modes defined as direct and delayed translation. Here, genes of distinct functional processes are under the control of direct and delayed translation. The response of pollen to elevated temperature occurs rather at proteome, but not as drastic at the transcriptome level. Heat shock proteins, proteasome subunits, ribosomal proteins and eukaryotic initiation factors are most affected. On the example of heat shock proteins we demonstrate a decoupling of transcript and protein levels as well as a distinct regulation between the developmental stages. CONCLUSIONS: The transcriptome and proteome of developing pollen undergo drastic changes in composition and quantity. Changes at the proteome level are a result of two modes assigned as direct and delayed translation. The response of pollen to elevated temperature is mainly regulated at the proteome level, whereby proteins related to synthesis and degradation of proteins are most responsive and might play a central role in the heat stress response of pollen.

The monitoring of liquid-filled tubes with respect to the formation of soft deposition layers such as biofilms on the inner walls calls for non-invasive and long-term stable sensors, which can be attached to existing pipe structures. For this task a method is developed, which uses an ultrasonic clamp-on device. This method is based on the impact of such deposition layers on the propagation of circumferential guided waves on the pipe wall. Such waves are partly converted into longitudinal compressional waves in the liquid, which are back-converted to guided waves in a circular cross section of the pipe. Validating this approach, laboratory experiments with gelatin deposition layers on steel tubes exhibited a distinguishable sensitivity of both wave branches with respect to the thickness of such layers. This allows the monitoring of the layer growth.
