In normal greenhouse condition, coda - transgenic wheat lines ( to ) had the same plant morphorlogy and pollen i2 - ki staining rate as untransformed control plant. after treating with 300 mm of 5 - fc, however, changes in configurations of spikelet, floret and anther have been observed in the transgenic lines but not in the control, and 50 % gus - positive lines displayed outside - opened glume, abnormal stamen, smaller and thinner anther, shorter filament, and failure of selfing. in parts of 5 - fc - treated transgenic lines, the pollen staining rate by i2 - ki was much lower than that of untransformed control
溫室栽培的轉基因小麥苗( t _ 0 )未噴5 - fc處理時植株外部形態和花粉碘-碘化
鉀染色的著色率與未轉基因的對照沒有差異;用300mm的5 - fc處理后,發現有50 gus陽性株
系與對照有明顯的區別,表現為小穗穎殼外張,花絲短縮,花藥發育不良,較小、黃白色且花粉粒少,自花不授粉,無外來花粉授粉則不結實。
