Nanoencapsulation with proteoliposomes from natural membranes has been proposed
as a carrier for the highly efficient delivery of mineral nutrients into plant tissues. Since Boron
deficiency occurred frequently in crops, and is an element with low movement in tissues, in this work,
nanoencapsulated B vs free B was applied to in vitro sweet potato plants to investigate the regulation
of B transporters (aquaporins and specific transporters). Additionally, an metabolomic analysis was
performed, and mineral nutrient and pigment concentrations were determined. The results showed
high increases in B concentration in leaves when B was applied as encapsulated, but also Fe and
Mn concentration increased. Likewise, the metabolomics study showed that single carbohydrates of
these plants could be related to the energy need for increasing the expression of most NIP aquaporins
(NIP1;2, NIP1;3; NIP4;1, NIP4;2, NIP5;1, NIP6;1, and NIP7) and boron transporters (BOR2, BOR4 and
BOR7;1). Therefore, the results were associated with the higher mobility of encapsulated B into leaves
and the stimulation of transport into cells, since after applying encapsulated B, the aforementioned
NIPs and BORs increased in expression.
