title: [A new subtype of potato class I patatin gene].
abstract: Potato class I and class II patatin gene belong to a multigene family with different tissuespecific expression patterns. A class I patatin gene was isolated from a genomic library of Chinese potato cultivar "Dongnong 303" (Solanum tuberosum) by using class II patatin promoter as probe. A 1.8kp DNA sequence was determined, including 1407bp of patatin gene 5' flanking sequence and 363bp of patatin structure gene. Its 5' flanking sequence showed that it is a class I patatin gene. Compared with six reported subtypes of class I patatin genes, there are a large fragment of deletion and insertion in its 5' flanking sequence. Therefore, it might be a new subtype of class I patatin gene.
