Ethylene promotes fruit ripening, including softening. The fruit of melting-flesh peach (Prunus persica (L). Batsch) cultivar 'Akatsuki' produces increasing levels of ethylene, and the flesh firmness softens rapidly during the ripening stage. On the other hand, the fruit of stony hard peach cultivars 'Yumyeong', 'Odoroki', and 'Manami' does not soften and(More)
Many important apple (Malus × domestica Borkh.) fruit quality traits are regulated by multiple genes, and more information about quantitative trait loci (QTLs) for these traits is required for marker-assisted selection. In this study, we constructed genetic linkage maps of the Japanese apple cultivars 'Orin' and 'Akane' using F1 seedlings derived from a(More)
Using 11 consensus primer pairs designed from S-linked F-box genes of apple and Japanese pear, 10 new F-box genes (MdFBX21 to 30) were isolated from the apple cultivar ‘Spartan’ (S 9 S 10 ). MdFBX21 to 23 and MdFBX24 to 30 were completely linked to the S 9 -RNase and S 10 -RNase, respectively, and showed pollen-specific expression and S-haplotype-specific(More)
Burning mouth syndrome (BMS) is an idiopathic orofacial pain condition. Although the pathophysiology of BMS is not clearly understood, central and peripheral neuropathic mechanisms are thought to be involved. The authors compared brain response to noxious heat stimuli in 16 right-handed women with primary BMS and 15 sex- and age-matched right-handed healthy(More)
We investigated the genetic diversity of 42 plum varieties by RAPD analysis. Twenty primers discriminated all plum varieties excepting two synonymous pairs: 'Botankyou and ‘Kelsey’, and ‘Chairn’ and ‘Tragedy’. Two North American plums, ‘Beach Plum’ and ‘Glow’, were genetically distinct from the other plums by cluster analysis. Overlaps observed between the(More)
Identification of markers associated with genes of interest and quantitative trait loci (QTLs), combined with high-density genetic linkage maps, can help reduce labor and costs by enabling marker-assisted selection (MAS). In this study, a dwarfing apple rootstock cultivar ‘JM7’ (Malus prunifolia × Malus pumila ‘Malling 9’) and wild apple Malus sieboldii(More)
In this study, we investigated the ability of auxin to promote ethylenebiosynthesis in fruit tissue. Discs prepared from preclimacteric peach fruit(Prunus persica L. Batsch cv.Akatsuki) were incubated for 3 weeks on a solid MS medium containing variousconcentrations of 1-naphthaleneacetic acid (NAA). Higher ethylene productionwasobserved with an increasing(More)
'Fuji' is one of the most popular and highly-produced apple cultivars worldwide, and has been frequently used in breeding programs. The development of genotypic markers for the preferable phenotypes of 'Fuji' is required. Here, we aimed to define the haplotypes of 'Fuji' and find associations between haplotypes and phenotypes of five traits (harvest day,(More)
Vegetative propagation enables the multiplication of plants that are genetically identical to the original. Hardwood cuttings have a low cost advantage and are used widely for the propagation of JM series apple rootstocks, which root well from hardwood cuttings. To breed new apple rootstocks with similarly high rooting capabilities, the development of a(More)
We present a measurement of the standard model CP violation parameter sin2 phi(1) (also known as sin2beta) based on a 10.5 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) collider. One neutral B meson is reconstructed in the J/psiK(S), psi(2S)K(S), chi(c1)K(S), eta(c)K(S), J/psiK(L), or(More)
