METHOD FOR DETECTING PATHOGEN CANDIDATUS PHLOMOBACTER FRAGARIAE CAUSATIVE OF STRAWBERRY MARGINAL CHLOROSIS

摘要

By detecting Ca. P. fragariae at an early stageand removing the same from production sites of strawberry seedlings and fruits, it is expected that the spreading of strawberry marginal chlorosis can be prevented and damage on the fruit production can be reduced. Thus, the purpose of the present invention is to provide a technique whereby Ca. P. fragariae can be detected at a high sensitivity. For this purpose, provided is a nucleic acid molecule comprising: (a) a sequence represented by one of SEQ ID NOS:1-5; (b) a sequence having a homology of at least 95% to the sequence of (a) or being hybridizable to a complementary strand thereof under stringent conditions, or a variant sequence derived from the sequence by substitution, addition and/or deletion of one to several bases; (c) a fragment sequence containing at least 10 nucleotides in (a) or (b); or (d) a complementary strand sequence of (a), (b) or (c).
