AI Technical Summary

Technical Problem

Existing Agrobacterium-mediated plant callus infection devices require the repeated use of tools such as tweezers to transfer callus tissue during infection and subsequent treatment, resulting in physical damage, affecting cell structure and regeneration capacity, and reducing transformation efficiency.

Method used

A device for Agrobacterium-mediated plant callus infection was designed. Through the cooperation of connecting rods, threaded rods and clamping blocks, the movable plate can be flexibly adjusted to ensure full contact between the callus tissue and the bacterial solution. The bacterial solution is then absorbed by a grid-type filter and sterile filter paper, reducing the risk of damage and contamination during the transfer process.

Benefits of technology

It improves infection efficiency and uniformity, reduces the risk of callus damage and contamination, and ensures the vitality and regeneration capacity of callus.

Abstract

本实用新型公开了一种农杆菌侵染植物愈伤装置,属于生物技术领域,其包括瓶体,瓶体一侧滑动连接有连杆,连杆为U字型结构,连杆内端底部固定连接有活动板,活动板位于瓶体内部并与瓶体内壁滑动连接,而活动板顶部放置有多组愈伤组织,卡槽位于压板的下方;本实用新型通过通过连杆、螺纹杆和夹块的配合,可以灵活地将活动板调整到靠近瓶体底部的位置,提高了侵染的均匀性,传统的操作方式通常需要将愈伤组织从侵染容器中转移到无菌滤纸上进行吸干操作,将活动板移动到瓶体上方后,直接在瓶体内通过压板挤压无菌滤纸吸走愈伤组织表面的菌液,无需将愈伤组织转移出瓶体,减少了对愈伤组织的移动,大大降低了愈伤组织损伤和污染的风险。
