use of sucrose in plants

I am trying to infect a plant with Agrobacterium rhizogenes and the protocol it mentions the use of MgCl 2. The sucrose is produced by photosynthesis that turn into specialized cells in the veins of their leaves. Thus, the structure of a sucrose molecule, its physical and chemical properties, and its uses are discussed briefly in this article. So I would like to know the role of MgCl 2 in this procedures. In other plants a much lower hexose-to-sucrose ratio was found. Once the sucrose has reached the sink, it can either be hydrolysed directly (into glucose + fructose) for energy or alternatively used to synthesise polymers such as starch and cellulose. Sucrose moves from sources (e.g. Consumption of sucrose increased from the 19th century onwards, partly due to its widespread use in the agri-food industry. Sucrose will then be transported into the phloem by plant cells, the special vascular tissue intended for sugar transport. The sucrose is produced by photosynthesis that turn into specialized cells in the veins of their leaves. Table sugar is sucrose, synthesised by plants such as sugar cane and sugar beet. Plants use an ekectrogenic pump, a proton pump and a con transport protein to load sucrose. In chemical terms, sucrose is a disaccharide (‘double’ sugar) formed from a glucose molecule and a fructose molecule. Finally, the use of a neurofuzzy logic technology allowed us to deduce the best plant growth conditions (2.3% sucrose and 122–130 µmol m −2 s −1), taking in account all the parameters measured, required for the highest quality of acclimatized plantlets to be obtained and increased our understanding of the interactions and the role of the main factors involved in plant acclimation. root) via phloem, which is a plant vascular system that transports photosynthates around the plant. Inside the cells, sucrose is converted back to glucose and fructose. So plants uses the sucrose as a medium to transfer energy. These experiments were conducted using the facilitated-exudation technique introduced by King and Zeevaart (1974), in which ethylenediaminetetraacetic acid (EDTA) is used to prevent the sieve tubes of … Furthermore, the use of transgenic plants specifically impaired in sucrose transporter expression has provided strong evidence that SUT1 transporter function is required for phloem loading. leaf) to a sinks (e.g. So plants transfer glucose and fructose in the form of sucrose in order to: Increase energy storage Plants use an ekectrogenic pump, a proton pump and a con transport protein to load sucrose. Being a complex structure, sucrose is not as much reactive as glucose. Energy is yielded when it is needed. Physiological analyses of these plants demonstrate that sucrose transporters are essential components of the sucrose translocation pathway at least in potato and tobacco. Thanks!
