Little has been known about the tube cells in the blades, especially the thin-walled tissues of the ligaments. Recently, German and American researchers used single-cell sequencing for the first time to conduct a comprehensive analysis of the athropomorthytic mustard leaf tube cells. The paper was published in Plant Cells.
researchers successfully isolated plant cells for the first time and created a map that contains all the regulated RNA molecules of the leaf tube system to determine the role of different cells by analyzing metabolic pathways.
systems of plants play a key role in transporting solutes from the production area to the storage or use area. Sugars and amino acids are transported from the leaves to the roots and seeds through the ligaments.
the ligament is part of the vitulation plant tissue and consists of sieve elements (where the actual shift occurs), as well as the accompanying cells and thin-walled cells of the ligament. The veins are made up of at least 7 different cell types that play a specific role in transport, metabolism and signaling.
addition, the team confirmed for the first time that sugar and amino acid transporteres have been found in thin-walled cells in the ligaments, which transport these compounds from the production area to the tube system. These compounds are then entered into the sieve elements through a second group of transporters and then output from the blades.
researchers say the analysis provides new insights into the role and relationship between leaf tube systems and individual leaf cell types. Collaborations among working groups have made it possible to use new methods to gain insight into important cells in plant pathways for the first time, thus laying the foundation for a better understanding of plant metabolism.
