Representative genotype of transformants. (a) Southern blot analysis of the MK transformants. Southern blot analysis was carried

out against MluI-digested genomic DNA using the mokB fragment as the probe. The mokB fragment was amplified by PCR with

primers mokB-f and mokB-r. Lanes C1, cosmid 12-33; C2, cosmid sCnDmokB; W, A. oryzae NS4 strain; M, λ-EcoT14I digest DNA

marker; 1, M12-33-5; 2 to 4, candidate transformants (MK5-1,3,4); 5, M12-33-17; 6 to 9, candidate transformants (MK17-1, 2, 5,

6); 10, M12-33-18; 11, candidate transformants (MK18-1). The bands indicated by arrow were derived from cosmid 12-33. The

band indicated by arrowhead was derived from sCnDmokB. (b) Southern blot analysis of the MK-L transformants. Southern blot

analysis was carried out against SnaBI-digested genomic DNA using the AolaeA PCR fragment (amplified by AolaeA-3f: 5’-

atggcctaatgtacgccc-3’, AolaeA-3r: 5’-ctcctgcagagtctcggat-3’) as the probe. Lanes V, pPTRI-laeA; M, λ-EcoT14I digest DNA

marker; 1, M12-33-17 strain; 2, MK-L1; 3, MK-L2.

The band indicated by arrow was derived from pPTRI-laeA. The band indicated by arrowhead was the signal of native laeA gene.

(c) Southern blot analysis of KsMK transformants. Southern blot analysis was carried out against EcoRI-digested genomic DNA

using the mokA or mokB2 PCR fragment (amplified by mokA-f, -r or mokB-2f, -2r primer sets) as the probe. Lanes: H, A. oryzae

host strain (Ks31); 6, 21, candidate transformants (KsMK-6, 21). (d) Southern blot analysis of TQ transformants. Southern blot

analysis was carried out against KpnI-digested genomic DNA using the tdiD PCR fragment as a probe. Lanes: V, TQ gene cluster

expression vector sCsCTQ; M, λ-EcoT14 digest DNA marker; H, Ks31 host; 25, 33, 34,36, 39, 47, 52, 53, candidate transformants

(KsTQ-25, 33, 34, 36, 39, 47, 52, 53). The arrowhead indicated the position of 9.4 kb.
