TL;DR: The rice seed-storage protein glutelin promoter, GluB-1, was used to drive expression of the soybean gene specifically in developing, self-pollinated seeds (T1 seeds) of transgenic plants, as confirmed by reverse transcription PCR analysis.

TL;DR: Transgenic rice plants expressing mouse dominant T cell epitope peptides of Cry j I and Cry j II allergens of Japanese cedar pollen are developed as a fusion protein with the soybean seed storage protein glycinin for the induction of oral tolerance to pollen allergens.

TL;DR: The mean Fe concentration in leaves of ferritin over-expressing lines decreased to less than half of the non-transformant while that the plant biomasses and seed yields of the ferrit in-transformed lines were not significantly different from those of theNon-transformants, suggesting that accumulation of Fe in seeds of hyper-expression ferritIn rice did not always depend on the expression level of exogenousFerritin but may have been limited by Fe uptake and transport.

TL;DR: Results indicate that the GCN4 motif acts as an essential element determining endosperm-specific expression and that the AACA, ACGT and Prolamin-box are involved in quantitative regulation of the GluB-1 gene.

TL;DR: The isolated RPBF trans-activated several storage protein genes via an AAAG target sequence located within their promoters, and with methylation interference experiments the additional AAAG-like sequences in promoters of genes expressed in maturing seeds were recognized by the RPBF protein.
