Rice vacuum permeation genetic transformation device

The invention relates to a rice vacuum permeation genetic transformation device. The middle part of a supporting table top of the device is provided with a through hole; a bottom plate is arranged on the supporting table; the middle parts of the upper and lower surfaces of the bottom plate are respectively provided with an upper cylinder and a lower cylinder; a magnet ring II and a magnet ring I are respectively sheathed on the upper cylinder and lower cylinder; the adjacent magnetic poles of the magnet ring I and magnet ring II are homopolar; the lower cylinder and magnet ring I penetrate through the through hole and are positioned under the table top; a vacuum permeation genetic transformation chamber is arranged on the bottom plate; the upper cylinder is positioned in the chamber; a bracket is arranged on the magnet ring II and provided with a permeation solution container; the upper inner wall of the chamber is provided with an annular loading platform, an air vent pipe with a valve, and a vacuum air exhaust connecting pipe; and the bottom end port and top end port of the chamber are respectively provided with a seal ring. The device can perform transformation on the plant to be transformed in the vacuum state immediately after the plant starts contacting the permeation solution, implements in-situ genetic transformation on the rice in the vacuum state in deed, and enhances the infecting potential of agrobacterium for the plant. The device is applicable to both smaller and bigger crop individuals.
