Scanning electron microscopy observation of the nectaries in the transgenic plants and their control in B. rapa ssp. chinensis var. parachinesis. ac are wild types, dg are pCAMBIA transgenic plants, hi are pCAMBIA-BcNS transgenic plants. The arrow in H refers to the forking of the nectary development. The arrows in b, e, and G refer to the stoma of the nectary. The results indicate that not all of the nectaries were constantly open (f); some were closed (i) or half-closed (c)
