Map the molecules of plant science

cells of any organism contain complete genetic information, or a biological "blueprint" that encodes a sequence of so-called DNA nucleotide building blocks. But how do plants create all kinds of tissues? Like the leaves that convert light energy into chemical energy and produce oxygen, or the roots that absorb nutrients from the soil? The answer lies in the protein patterns of the cells in their respective tissues.
protein is the main molecule in each cell. They are biocatalysts that transmit signals within and between cells, form cell structures, and so on. Bernhard Kuster, professor of proteomics and bioanalytical analysis at the University of Technology In Munich, Germany, explains: "To form these protein patterns, it is not only what proteins are present in the tissue, but also the quantity. "For example, proteins associated with the mechanism of photoxynthy are found mainly in leaves and in seeds, but at 1,000 times lower levels.
team used bio-chemical and high-volume analysis methods to test the athropomorthic mustard model to find out more about its molecular composition. The paper was published recently in Nature.
40 years, this humble weed with small white flowers has been the "laboratory mouse" of plant biology. The fact that it is small and easy to grow, and that insights from basic research on athymethyst can often be transferred to crops, also makes athropophymesan an interesting target for plant breeding research.
researchers say most of the data is generated using liquid chromatography, a series mass spectromety, which analyzes thousands of proteins simultaneously in an experiment, while biometrics can help analyze large amounts of data. "For the first time, we have fully mapped all the proteins in the plant tissue of the athropomorthic mustard model. This gives us a new understanding of the complex biology of plants. Kuster said.
The results of all the studies are summarized in a virtual att chart that provides a preliminary answer to the question of how many of the 27,000 genes are proteins (> 18,000); All data is available free of charge in ProteomicsDB's online database.
future, researchers will turn their attention to crop analysis to study how proteomics change when plants are attacked by pests, or how plants adapt to climate change.
