Grafted plant body and method for producing same

Abstract

Provided is a novel plant body comprising a plant tissue of a plant belonging to the family Solanaceae, Brassicaceae, Lamiaceae, or Orobanchaceae, wherein graft incompatibility is avoided or suppressed by using a graft medium between different-family plants.

1 . A graft medium between different-family plants, the graft medium comprising a plant tissue of a plant belonging to the family Solanaceae, Brassicaceae, Lamiaceae, or Orobanchaceae. 
     
     
         2 . The graft medium according to  claim 1 , which is a graft medium between different-order plants. 
     
     
         3 . The graft medium according to  claim 1 , wherein the plant tissue is a plant tissue of a plant belonging to the family Solanaceae. 
     
     
         4 . The graft medium according to  claim 1 , wherein the plant tissue is a plant tissue of a plant belonging to the genus  Nicotiana.    
     
     
         5 . A plant tissue comprising two different-family plant tissues grafted through the graft medium according to  claim 1 . 
     
     
         6 . A method for producing a plant tissue, comprising grafting two different-family plant tissues through the graft medium according to  claim 1 . 
     
     
         7 . A plant tissue comprising a plant tissue of a plant belonging to the family Solanaceae, Brassicaceae, Lamiaceae, or Orobanchaceae, and a different-family plant tissue grafted with each other. 
     
     
         8 . A plant body comprising the plant tissue according to  claim 5 . 
     
     
         9 . The plant body according to  claim 8 , comprising a plant tissue of cultivar. 
     
     
         10 . A method for producing a crop, comprising harvesting a crop from the plant body according to  claim 9 . 
     
     
         11 . A method for screening a graft medium between graft-incompatible plants, comprising steps (a) to (c):
 (a) grafting a subject plant tissue with a different-family plant tissue;   (b) culturing a plant body obtained in step (a); and   (c) when the plant body does not die after step (b), selecting the subject plant tissue as a graft medium between graft-incompatible plants.   
     
     
         12 . A method for screening a graft medium between graft-incompatible plants, comprising steps (d) to (f):
 (d) grafting plant tissues of plants belonging to two different families through a subject plant tissue;   (e) culturing a plant body obtained in step (d); and   (f) when the plant body does not die after step (e), selecting the subject plant tissue as a graft medium between graft-incompatible plants.   
     
     
         13 . A medium for delivering a useful component to a different-family plant, the medium comprising a plant tissue of a plant belonging to the family Solanaceae, Brassicaceae, Lamiaceae, or Orobanchaceae. 
     
     
         14 . A plant tissue comprising the delivery medium according to  claim 13  grafted with a different-family plant tissue. 
     
     
         15 . A plant body comprising the plant tissue according to  claim 14 . 
     
     
         16 . A method for producing a plant body to which a useful component is delivered, the method comprising delivering a useful component to the plant body according to  claim 15  through the delivery medium according to  claim 13  contained in the plant body.
