Effect of a New Compound on the Mitotic Polyploidization of Lilium Longiflorum and Oriental Hybrid Lilies
A new compound, Surflan (Surflan), for mitotic polyploidization in vitro in lily was tested and compared with the original compound ‘oryzalin’. Surflan was effective for mitotic polyploidization of lilies. The optimal concentration of Surflan was 0.0075% for in vitro chromosome doubling. A low concentration (0.0025%) was still effective to produce polyploid plants, however, a high concentration...
متن کاملValidation of Reference Genes for Quantitative Real-Time PCR during Bicolor Tepal Development in Asiatic Hybrid Lilies (Lilium spp.)
Quantitative real-time PCR (qRT-PCR) is a reliable and high-throughput technique for gene expression studies, but its accuracy depends on the expression stability of reference genes. To date, several reliable reference gene identifications have been reported in Lilium spp., but none has been obtained for lily tepals at different developmental stages. In this study, ten candidate reference genes...
متن کاملGlobal Transcriptome Profiling Analysis of Inhibitory Effects of Paclobutrazol on Leaf Growth in Lily (Lilium Longiflorum-Asiatic Hybrid)
As a popular ornamental flower, potted lily is an important object of lily breeding. Paclobutrazol, a chemical growth retardation compound, is often used to dwarf plant in producing potted lilies. However, in recent years, the plants with inherited dwarf traits by using genetic engineer breeding technology are being developed. The studies on molecular basis of lily dwarfism will offer some targ...
متن کاملAuxin involvement in tepal senescence and abscission in Lilium: a tale of two lilies
Petal wilting and/or abscission terminates the life of the flower. However, how wilting and abscission are coordinated is not fully understood. There is wide variation in the extent to which petals wilt before abscission, even between cultivars of the same species. For example, tepals of Lilium longiflorum wilt substantially, while those of the closely related Lilium longiflorum×Asiatic hybrid ...
متن کاملA Calcium-Activated Phytase from Pollen of Lilium longiflorum.
A phytase was isolated and partially purified from the pollen of Lilium longiflorum Thumb. Optimum activity was at pH 8.0. The phytase was activated by Ca(2+) and Sr(2+) but not by the other divalent cations tested. Activity was inhibited by ethylenediaminetetraacetate. The phytase had a temperature optimum of 55 to 60 degrees C and an activation energy of about 12,700 calories/mole. Extraction...
