New male sterile mutant in cucumber (Cucumis sativus L.) : inheritance, genetic relationship to other mutants and sex types, and response to chemical and environmental factors

Creator:

Zhang, Qi (Qi Qun), 1956-

Abstract:

A new male sterile (MS) mutant was found in 1988 in an inbred line of cucumber (Cucumis sativus L.) in the greenhouse of Sunseeds Company. The mutant is characterized by normal corolla in both male and female flowers, normal fertility in the female, and absence of pollen in otherwise normal-appearing...

Maintenance of normal vegetative growth via attenuation of barnase as an agent of floral tissue ablation in Populus

Creator:

Wei, Hao

Abstract:

To reduce the environmental impacts caused by gene flow from transgenic trees, reproductive sterility genes have been developed that use a floral regulatory element linked to a cell toxin. This results in dysfunction or ablation of floral tissues, causing sterility. However, floral promoters often permit low levels of expression in...
