The R2R3-type protein IbMYB1 is a key regulator of anthocyanin biosynthesis in the storage roots of sweet potato [Ipomoea batatas (L.) Lam]. Previously, we demonstrated that IbMYB1 expression stimulated anthocyanin pigmentation in tobacco leaves and Arabidopsis. Here, we generated dual-pigmented tra

Plastid engineering provides several advantages for the next generation of transgenic technology, including the convenient use of transgene stacking and the generation of high expression levels of foreign proteins. With the goal of generating transplastomic plants with multiresistance against both p

BACKGROUND: Plants respond differently to mechanical wounding and herbivore attack, using distinct pathways for defense. The versatile sweet potato sporamin possesses multiple biological functions in response to stress. However, the regulation of sporamin gene expression that is activated upon mecha

… In this study, the vacuolar sorting signal (VSS) of sporamin was fused to the heavy (H) and light (L) chains of a mouse monoclonal antibody (mAb), and the mAb was produced in suspension-cultured tobacco BY2 cells. … These results suggest that the sporamin signal peptide fused to mAb acts as a VSS and leads to the increase in the amount of Man_3FucXylGlcNAc_2, which is the main N-glycan structure in vacuoles. …
