Abstract

Lettuce is an economically important green-yellow vegetable crop cultivated in many countries, but there is some difficulty in commercial production due to its susceptibility to high temperature and diseases in such humid climatic areas as Japan. Therefore, breeding of lettuce has focused on improving resistance to high temperature and diseases by conventional crossings between lettuce cultivars. Although wild lettuce species have resistance to downy mildew pathogen, etc., they cannot be readily crossed with lettuce. Recently, gene manipulation techniques such as cell fusion and transformation by electroporation or a binary vector system through Agrobacterium infection, etc., have been developed as useful tools for improving crops. Consequently, the introduction of genes rendering disease resistance and other useful traits to lettuce using biotechnology is expected in the near future.
