Characteristics related to grain quality and starch viscosity were investigated in three independent japonica transgenicrice lines expressing a Protox gene from Bacillus subtilis and compared to the control. In this study, we found that there were nosignificant diferences between the transgenic lines and the control. All the transgenic lines were comparable in grain size, millingquality, appearance quality and physicochemical properties to the control that were derived from. The viscosity of the starch,breakdown values and setback value of the transgenic lines had similar to those of the control. In addition, textural properties ofposition of rice and properties of starch that determine the quality of rice and texture properties of cooked rice might provide usefulinformation for transgenic rice to rice breeder.

Thrips are known as cell-feeding sucking pests, but little information is available on which and how much of each subcellular fraction they ingest. In this study, the ingested amounts of nuclei and plastids in two representative thrips species (the western flower thrips, Frankliniella occidentalis, and the garden thrips, Frankliniella intonsa) along with two reference sucking pests (the two-spotted spider mite, Tetranychus urticae, a cell feeder, and the brown planthopper, Nilaparvata lugens, a sap feeder) were quantified by quantitative PCR using phytoene desaturase and rubisco as respective marker genes following feeding. The ingested amounts of plastids were significantly greater than those of nuclei in the thrips and mite species. In the thrips species, however, the fold differences in ingested amount between the two fractions were substantially lower than their original ratio in intact plant cells, suggesting that thrips ingest nuclei more selectively than plastids. Unlike the thrips species, the ratio between nuclei and plastids increased in T. urticae. In contrast to these cell-feeding insects, no subcellular fraction was detected in N. lugens. These findings suggest that transgenic expression of foreign hairpin RNA in the nucleus would deliver a substantial amount of target molecules to cell-feeding sucking pests, but not sap-feeding pests, when employing ingestion RNA interference-based control strategies.
