Opis:
This text is an attempt to seek answers about field and its multi-sensory experience in research work and social activities. The work experience of Lab of Social Initiatives DYM was thus collected and described in order to define two categories of the field and the process of its perception.

Opis:
Flower structure in grasses is very unique. There are no petals or sepals like in eudicots but instead flowers develop bract-like structures - palea and lemma. Reproductive organs are enclosed by round lodicule that not only protects reproductive organs but also plays an important role during flower opening. The first genetic model for floral organ development was proposed 25 years ago and it was based on the research on model eudicots. Since then, studies have been carried out to answer the question whether this model could be applicable in the case of monocots. Genes from all classes found in eudicots have been also identified in genomes of such monocots like rice, maize or barley. What's more, it seems that miRNA-mediated regulation of floral organ genes that was observed in the case of Arabidopsis thaliana also takes place in monocots. MiRNA172, miRNA159, miRNA171 and miRNA396 regulate expression of floral organ identity genes in barley, rice and maize, affecting various features of the flower structure, ranging from formation of lemma and palea to the development of reproductive organs. A model of floral development in grasses and its genetic regulation is not yet fully characterized. Further studies on both, the model eudicots and grasses, are needed to unravel this topic. This review provides general overview of genetic model of flower organ identity specification in monocots and it's miRNA-mediated regulation.

Opis:
MicroRNAs are short molecules of 21-24 nt in length. They are present in all eukaryotic organisms and regulate gene expression by guiding posttranscriptional silencing of mRNAs. In plants, they are key players in signal transduction, growth and development, and in response to abiotic and biotic stresses. Barley (Hordeum vulgare) is an economically important monocotyledonous crop plant. Drought is the world's main cause of loss in cereal production. We have constructed a high-throughput Real-Time RT-qPCR platform for parallel determination of 159 barley primary microRNAs' levels. The platform was tested for two drought-and-rehydration-treated barley genotypes (Rolap and Sebastian). We have determined changes in the expression of primary microRNAs responding to mild drought, severe drought, and rehydration. Based on the results obtained, we conclude that alteration in the primary microRNA expression is relative to the stress's intensity. Mild drought and rehydration mostly decrease the pri-miRNA levels in both of the tested genotypes. Severe drought mainly induces the primary microRNA expression. The main difference between the genotypes tested was a much-stronger induction of pri-miRNAs in Rolap encountering severe drought. The primary microRNAs respond dynamically to mild drought, severe drought, and rehydration treatments. We propose that some of the individual pri-miRNAs could be used as drought stress or rehydration markers. The usage of the platform in biotechnology is also postulated.

Opis:
MicroRNAs are 19- to 24-nt-long single-stranded RNAs that are crucial regulators of gene expression which control plant development and response to environmental cues. We have analyzed microtranscriptomes of five barley developmental stages. Generally, during the barley development, miR168-3p and miR1432-5p levels increase while the 5'U-miR156-5p level decreases (with exception for the 2-week-old barley). We have identified two miR156-5p izomiRs (called 5'U-miR156-5p [20 nt] and 5'UU-miR156-5p [21 nt]), which were expressed differently during barley development. The 5' U-miR156-5p level decreased in 3-week-, 6-week-, and 68-day-old barley, when compared to the 1-week-old plants. Meanwhile, the 5' UU-miR156-5p level increased significantly in the 68-day-old barley plants. Moreover, only the 5' U-miR156 isomiR recognizes and guides unique transcription factor mRNAs from the Squamosa Promoter Binding Protein-Like (SPL) family. We identified many non-canonical microRNAs with changed expression levels during the barley development. Here, we present the profiles of microRNA expression characteristics for particular barley developmental stages. These analyses are accompanied by the experimental degradome analysis of miRNA targets.
