PLANT SYSTEM FOR COMPREHENSIVE GENE FUNCTION ANALYSIS WITH THE USE OF FULL-LENGTH CDNAS

摘要

A gene causative of a phenotype character is easily specified and thus gene functions are comprehensively analyzed. A method of analyzing a gene function which comprises: (a) infecting a plant mass with a full-length cDNA library containing an expression regulatory sequence to thereby transfer the cDNA into the plants; (b) individual plants fulfilling desired requirements are selected from the plants having the cDNA transferred thereinto as described above; (c) isolating the above-described cDNA from the selected plants; and (d) re-transferring the thus isolated cDNA into a plant of the same species as the transgenic plants as described above to thereby reconfirm the phenotype character depending on the selection requirements as described above.
