Seed Metabolome Analysis of a Transgenic Rice Line Expressing Cholera Toxin B-subunit


ABSTRACT: Rice (Oryza sativa L.) is a candidate crop for production of plant-based vaccines by genetic engineering technologies. MucoRice-CTB has been developed as a rice-seed-based vaccine against cholera by transgenic expression of modified cholera toxin B-subunit (CTB) under the RNA interference (RNAi)-mediated suppression of endogenous seed storage proteins. Here, we performed non-targeted metabolomic profiling of MucoRice-CTB to understand the overall effects of the genetic engineering on rice seed metabolism using gas chromatography/time-of-flight mass spectrometry.

Plant-based human vaccines have been actively developed in recent years, and rice (Oryza sativa L.) is one of the best candidate crops for their production and delivery. By expressing a modified cholera toxin B (CTB) subunit, we previously developed MucoRice-CTB, a rice-based vaccine against cholera, which is caused by infection of the intestine with the bacteria Vibrio cholerae. MucoRice-CTB lines have been extensively characterized by whole-genome sequencing and proteome analyses to evaluate t  ...[more]
