The Characteristics of Ultrastructure in the First Generation of Hot Pepper Seeds from Recoverable Satellite

To investigate the characteristics of change of hot pepper (Capsicum annuum L.) generation from seeds carried by recoverable satellite, we observed the ultrastructure of leaf mesophyll cells and pollen in the first generation (KL06-102hd) and ground control (KL06-102) with an electron microscope (EM). Seven primers amplified a total of thirty-six sites in genomic DNA of KL06-102 and KL06-102hd by random amplified polymorphic DNA (RAPD), of which eighteen sites were polymorphic. The results showed that the ultrastructure of the leaf mesophyll cells and the pollen grains in KL06-102hd changed. Perhaps these results suggested that space environment can induce the changes of hot pepper plant.
