Massive flowering of tropical Phalaenopsis orchids is coordinated by the cold-induced release of reproductive bud dormancy. Light and temperature are the two key factors integrated by the dormancy mechanism to both stop and reactivate the meristem development of many other angiosperm species, including fruit trees and ornamental plants. It is well(More)
The influence of sequence context on the ability of DNA polymerase to bypass sites of base loss was addressed using an in vitro selection system. Oligonucleotides containing either an aldehydic abasic site or tetrahydrofuran surrounded by four randomized bases on both the 5' and 3' sides were used as templates for synthesis by phage T4 DNA polymerase(More)
The FVE gene is considered a classical flowering time locus and affects flowering through the autonomous pathway. In this study, a FVE homologue gene was isolated from Doritaenopsis ‘Tinny Tender’ (Doritaenopsis Happy smile × Happy valentine) and designated as DhFVE. The full-length DhFVE cDNA was 1,856 bp with a 1,407 bp open reading frame and it encodes(More)
The EARLY FLOWERING 4 (ELF4) gene has been reported as a requirement for photoperiod perception and circadian function. In this study, an ELF4 homolog gene EARLY FLOWERING 4-like4 (EFL4) was isolated from Doritaenopsis “Tinny Tender” (Doritaenopsis Happy Smile × Happy Valentine) and designated as DhEFL4. The acquired DhEFL4 cDNA was 593 bp with a 345 bp(More)
Not only the first systematic characterization of CAO gene in bamboo species, but also the first attempt to study the relationship between CAO gene expression and bamboo leaf color variation. Chlorophyllide a oxygenase (CAO) converts chlorophyllide (Chlide) a to Chlide b and hence plays an important role in chlorophyll (Chl) b biosynthesis. In this study, a(More)
Phyllostachys vivax cv. aureocaulis is a widely planted ornamental bamboo with evergreen leaves. This plant's culm exhibits a golden-yellow background color marked randomly with narrow and broad green stripes but is occasionally light green with yellow stripes. In this study, we attempt to identify the molecular mechanism underlying the color variation in(More)
In vitro selection was used to define sequence contexts that significantly enhanced the mutagenic potential of 7, 8-dihydro-8-oxoguanine (8-oxoG). Contexts that simultaneously reduced the efficiency of 8-oxoG cleavage by formamidopyrimidine DNA N-glycosylase and increased the efficiency of misincorporating A opposite the lesion by DNA polymerase were(More)
In angiosperms, NADPH: protochlorophyllide oxidoreductase (POR) catalyzes the photoreduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide), the only light-dependent step in chlorophyll biosynthesis. There is a wide variety of gene organization and light- and development-dependent regulatory mechanisms for the POR genes. In this study, a POR(More)
Spontaneous leaf color variation in bamboo provides the opportunity to study the mechanisms of leaf color formation and the breeding of ornamental bamboos. Despite the fact that many genes are known to be involved in leaf color variation in model plants, molecular mechanisms governing natural leaf color variation in bamboo have remained obscure.
