| 1 | Engineered Cleistogamy in Camelina sativa for bioconfinement显示文摘Camelina sativa is a self-pollinating and facultative outcrossing oilseed crop.Genetic engineering has been used to improve camelina yield potential for altered fatty acid composition,modified protein profiles,improved seed and oil yield,and enhanced drought resistance.The deployment of transgenic camelina in the field posits high risks related to the introgression of transgenes into nontransgenic camelina and wild relatives.Thus,effective bioconfinement strategies need to be developed to prevent pollen-mediated gene f low(PMGF)from transgenic camelina.In the present study,we overexpressed the cleistogamy(i.e.f loral petal non-openness)-inducing PpJAZ1 gene from peach in transgenic camelina.Transgenic camelina overexpressing PpJAZ1 showed three levels of cleistogamy,affected pollen germination rates after anthesis but not during anthesis,and caused a minor silicle abortion only on the main branches.We also conducted field trials to examine the effects of the overexpressed PpJAZ1 on PMGF in the field,and found that the overexpressed PpJAZ1 dramatically inhibited PMGF from transgenic camelina to non-transgenic camelina under the field conditions.Thus,the engineered cleistogamy using the overexpressed PpJAZ1 is a highly effective bioconfinement strategy to limit PMGF from transgenic camelina,and could be used for bioconfinement in other dicot species. | Debao Huang Liwei Gao Jeremy McAdams Fangzhou Zhao Hongyan Lu Yonghui Wu Jeremy Martin Sherif MSherif Jayasankar Subramanian Hui Duan Wusheng Liu | 2023 | Horticulture Research2023，10，2： | 0 |
