Southern-blot analysis of the
β-amy1 structural gene in different barley cultivars.
Barley genomic DNA was digested with HindIII,
fractionated by agarose-gel electrophoresis, Southern blotted, and
hybridized with β-amy1 pcβC51 cDNA probe. The
genomic DNAs were from cv Adorra (lane 1), line 86-H2-64 (lane 2),
H. spontaneum PI 296897 (lane 3), and cv Haruna Nijo
(lane 4).
