Mechanism for the captation of nutrients in plants- unknown to date

oning. That is, for these first 90 minutes, the saccharose penetrates using the transporter mechanism while, parallely, the endocitosis phenomenon is activated to form microvesicles. Subsequently, the cell starts to capture huge quantities of saccharose through endocitosis.

The results of the research has shown, moreover, that only saccharose is capable of initiating endocitosis, given that, in the trials undertaken with substances similar to saccharose, such as glucose or fructose, the fact that none of these triggered the process could be confirmed.

Moreover, given that endocitosis is involved in the acquisition of substances for their subsequent conversion into "end products" (such as starch, oils, celluloses, etc.), basic knowledge of this mechanism provides great tips for the rational design of experiments aimed at enhancing vegetable species in the interest of humanity.

One of the great questions thrown up by the fact that saccharose pick-up is produced via endocitosis is, fundamentally, to find out if the saccharose captured through endocitosis is that involved in starch production. If this is the case, it will be necessary to discover what are the genetic and molecular mechanisms involved in the process, in order to improve the plant varieties. For example, in order to increase starch production in potato or maize, endocitosis would have to be encouraged through the stimulation of the genes involved in the formation of the vesicles ?a hypothesis that is currently being verified.
