Biosynthesis 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 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 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 کاملThe 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 کاملPatient with Morning Glory syndrome
A 6-year-old patient was referred to our ophthalmology service because of an ocular deviation (esotropia) on the right eye for 3 years. Best-corrected visual acuity in right eye and 20/20 in left eye. According to the Krimsky test, the patient showed 15 prism dioptres esotropia in right eye. No changes were observed in biomicroscopy of both eyes and funduscopy of left eye was normal. An optical...
