Arabidopsis Thaliana

Project proposal: AIMS - Bioinformatics method to support gene identification and characterization in Arabidopsis thaliana - Evaluation and integration of the accuracy of the Arabidopsis database Introduction: Arabidopsis thaliana is a model plant for research and a variety of wisely plant biology It is used to study aspects. The database has plentiful information on plants, including fully sequenced and annotated genomic sequences, extensive expression data, functional characterization data.

Arabidopsis thaliana is a small plant commonly used to study how plants grow and develop. Matthew Jackson and her colleagues studied seedling stems of Arabidopsis thaliana using a combination of microscope and computer technology. Experiments showed that these two epidermal cells appear to have different effects. Although hair-forming cells form hair-like structures and take up nutrients from the external environment, their neighboring atrial blast cells provide a rapid way for these nutrients to be unloaded and elevated. This pattern is not present in some other plants, including digitalis and opium poppy. It suggests that it may be an adaptation of Arabidopsis thaliana plants that can help them grow up in the specific environment the plant faces.

In plants Arabidopsis thaliana, vernalization requires several months exposure to temperatures between 0 and 6 ° C. Recently, the temperature required for the spring treatment of Arabidopsis thaliana of southern Europe differs and it turned out that it reacts to the temperature exceeding 6 ℃. This suggests that plants in northern Europe preferentially spring in cold temperatures. Here, Susan Duncan and colleagues compared the vernalization of Arabidopsis thaliana plants (or "plasmas") collected from different regions of Sweden and the UK.

A large amount of new knowledge on plant function is born from the study of molecular genetics of model plants. For example, Arabidopsis thaliana, Arabidopsis thaliana, weed species of Brassicaceae. The genomic information or genetic information contained in this kind of gene is encoded by approximately 135 million base pairs of DNA and forms one of the smallest genomes of flowering plants. Arabidopsis thaliana is the first plant sequenced in 2000. Sequencing of other relatively small genomes, rice (Oryza sativa) and Brachypodium distachyon, makes them an important model species for understanding crop genetics, cytology and molecular biology. , Grasses and monocots
