Deletion and reconstitution of STE12a.
(A) Map of the deletion plasmid construct, pYCC384.
(B) Map of STE12a reconstitution
construct, pYCC367. A, AseI; B, BamHI; X,
XbaI. (C) Southern blot analysis of the
Δste12a strain (I and
II) and STE12a reconstituted strain
(III). DNA was digested with AseI,
fractionated on an agarose gel, and transferred to a nylon membrane.
The resulting blot was hybridized with 2.1-kb
XbaI–AseI probe of STE12a
(I) or 3.6-kb XbaI–XbaI
probe of STE12a (II and
III). Wild type, B-4476;
Δste12a, TYCC384;
Δste12∷STE12a, C437.
(D) Hyphae formation on filament agar. Strains B-4476,
C490, TYCC245F1, and C489 were inoculated on filament agar. Photographs
were taken after 3 days of incubation at room temperature.
