Open AccessGenetic architecture of berry aroma compounds in a QTL (quantitative trait loci) map** population of interspecific hybrid grapes (Vitis labruscana × Vitis vinifera)
Although grapes accumulate diverse groups of volatile compounds, their genetic regulation in different cultivars remains unelucidated. Therefore, this study investigated the volatile composition in the berries...

Sharp eyespot of barley, bread wheat and durum wheat caused by Ceratobasidium cereale in Japan
Blighting of lower sheaths was found on barley, bread wheat and durum wheat grown in western Japan in April 2014, May 2016, and April 2019, respectively. A fungus, isolated repeatedly from the diseased plants ...

Head blight of durum wheat caused by Fusarium asiaticum
Fusarium asiaticum was repeatedly isolated from blighted spikes of durum wheat with head blight-like symptoms in our experimental fields in Fukuyama, Hiroshima Prefecture in western Japan, then demonstrated to be...

Development of SSR markers linked to QTL reducing leaf hair density and grapevine downy mildew resistance in Vitis vinifera
Dense leaf hairs of grapevines have been known to act as a preexisting defense structure for preventing the incidence of grapevine downy mildew, because the pathogen, Plasmopara viticola, needs water to invade gr...

Genetic dissection of quantitative trait loci for berry traits in interspecific hybrid grape (Vitis labruscana × Vitis vinifera)
Traits such as berry weight, firmness, and sweetness are important determinants of consumer choice and marketability of table grapes. Quantitative trait locus (QTL) analyses of berry traits have been conducted...

MYB diplotypes at the color locus affect the ratios of tri/di-hydroxylated and methylated/non-methylated anthocyanins in grape berry skin
Color variation in grape skin is mainly determined by the quantity and composition of anthocyanins. Anthocyanin quantities are mainly determined by the myeloblastosis (MYB) diplotypes at the color locus. We in...

Exploring quantitative trait loci for anthocyanin content in interspecific hybrid grape (Vitis labruscana × Vitis vinifera)
Anthocyanins affect the coloration of grape berry skin, which is an important determinant for consumer choice and grape marketability. Molecular mechanisms for anthocyanin accumulation in grape skin have been ...

Ectopic overexpression of peach GDP-d-mannose pyrophosphorylase and GDP-d-mannose-3′,5′-epimerase in transgenic tobacco
We created transgenic tobacco overexpressing peach GDP-d-mannose pyrophosphorylase (PpGMPH) and GDP-d-mannose-3′,5′-epimerase (PpGME), which are involved in the main l-ascorbate (Asc) biosynthetic pathway in plan...

Haplotype composition at the color locus is a major genetic determinant of skin color variation in Vitis ×labruscana grapes
Skin color is one of the most important fruit traits in grape, and has become greatly diversified due to hybridization and human selection. Many studies concerning the genetic control of grape color in Europea...

Spermidine levels are implicated in heavy metal tolerance in a spermidine synthase overexpressing transgenic European pear by exerting antioxidant activities
To verify whether spermidine synthase (SPDS) can confer long-term multi-heavy metal tolerance, in vitro shoots of a transgenic European pear (Pyrus communis L. ‘Ballad’) line #32 overexpressing apple SPDS (MdSPDS...

UDP-sugar biosynthetic pathway: contribution to cyanidin 3-galactoside biosynthesis in apple skin
UDP-galactose:flavonoid 3-O-galactosyltransferase (UFGalT) is responsible for cyanidin 3-galactoside (cy3-gal) synthesis from cyanidin (cy) and UDP-galactose (UDP-gal) which are, respectively, catalyzed by anthoc...

Importance of the l-galactonolactone pool for enhancing the ascorbate content revealed by l -galactonolactone dehydrogenase-overexpressing tobacco plants
l-Galactono-1,4-lactone (GalL) dehydrogenase (GLDH) is an enzyme that catalyzes the last step of l-ascorbate (AsA) biosynthesis in plants. To re-evaluate the importance of the enzyme and ...
