The speckled mutant of the Japanese morning glory blooms pale yellow flowers with fine and round colored spots, or speckles, distributed over the corolla. Since it also occasionally produces flowers with colored sectors apparently due to somatic mutations, the mutable speckled allele is thought to carry a transposable element. In this paper, we show that the appearance of the variegation phenotypes in the speckled mutant was controlled not only by the recessive speckled allele but also by a dominant genetic element, termed speckled-activator. Our results also indicated that the recessive c-1 mutation affecting pigmentation of flowers and mapped near the speckled locus causes a defect in a regulatory gene controlling the expression of structural genes for anthocyanin biosynthesis.

Although Japanese morning glory (Ipomoea nil (L.) Roth.) has been used intensively for genetic studies, DNA markers have not been developed in Ipomoea nil sufficient to cover all chromosomes. Therefore, we conducted microsatellite (simple sequence repeats, SSR) marker development in I. nil for future genetic studies. From 92,662 expressed sequence tag (EST) sequences, 514 unique microsatellite-containing ESTs were identified. Primer pairs were designed automatically in 326 SSRs. Of 150 SSRs examined, 75 showed polymorphisms among strains. A phenogram based on the SSR genotypes revealed the genetic relation among seven Japanese morning glories from five different regions of the world and an ivyleaf morning glory (I. hederacea Jacq.). The developed SSR markers might be applicable for genetic studies of morning glories and their relatives.
