The genetic basis of a flower color polymorphism in the common morning glory (Ipomoea purpurea).
The common morning glory (Ipomoea purpurea) is highly polymorphic for flower color. Part of this phenotypic variation is due to allelic variation at the P locus. This locus determines whether flowers will be purple or pink, where purple is dominant to pink. We have determined that the anthocyanin biosynthetic gene flavonoid 3'-hydroxylase (f3'h) corresponds to the P locus. In the pink allele of...
متن کاملBiosynthesis of wound ethylene in morning-glory flower tissue.
Production of wound ethylene was investigated in rib segments excised from flower buds of morning-glory (Ipomoea tricolor). Segments of the ribs were cut from buds 2 days before flower opening, floated overnight on 5 mm KCl solution, and transferred to agar the following morning. These immature segments evolved only a small quantity of ethylene during incubation on agar, with most of the produc...
متن کاملMorning glory syndrome.
Morning glory syndrome is a congenital optic disc anomaly in which much of the excavated colobomatous optic disc is filled with glial tissue. Ocular complications may include strabismus, reduced visual acuity and retinal detachment and it may have systemic associations as in Aicardi's syndrome. A patient with monocular morning glory syndrome and reduced visual acuity is reported. The pattern re...
متن کاملMethionine metabolism and ethylene biosynthesis in senescent flower tissue of morning-glory.
In immature rib segments prepared from morning-glory (Ipomoea tricolor) flower buds, the major soluble metabolite formed from tracer amounts of l-methionine-U-(14)C was S-methylmethionine (SMM). In segments of senescing ribs, (14)C was progressively lost from SMM and appeared in free methionine. Immature segments contained about 4 nmoles of free methionine and about 16 nmoles of SMM per 30 segm...
متن کاملStudies on Auxin Protectors. Protection by Protector-I V. On the Mechanism of IAA of the Japanese Morning Glory
The mechanism of auxin protection by auxin protector-I (Pr-I) of the Japanese morning glory was studied in vitro. Four lines of evidence indicate that Pr-I acts as a strong reductant which prevents 'the peroxidase-catalyzed oxidation of IAA: 1) The kinetics of the reaction are best explained on this basis. 2) The Pr-I-induced lag preceding auxin destruction by peroxidase is completely eliminate...
