Abstract

The present study reports the presence of folate binding proteins (FBPs) in the plants, coriander and Arabidopsis, and their contributions toward folate enhancement. After observing that salicylic acid (SA) enhanced the accumulation of folates in coriander, a study was conducted in Arabidopsis, where twofold increase in folates occurred in foliage upon SA treatment. For obtaining insights into genes involved in SAinduced folate accumulation, microarray data of responsive genes in Arabidopsis were screened. Based on the expression profiles, 19 genes were further analysed by qPCR. The results revealed that folate biosynthetic genes were largely down-regulated, whereas a gene of a putative folate-binding protein (FPB) was upregulated, which correlated with a significant increase of FPBs in foliage. This new information on a plant FBP appears useful for metabolic engineering of a wide range of crops to enhance the content and stability of the folates during post-harvest storage.
