Journal ArticleDOI
Effects of plant hormones and shading on the accumulation of anthocyanins and the expression of anthocyanin biosynthetic genes in grape berry skins
TL;DR: The accumulation of anthocyanins was enhanced by ABA treatment and suppressed by NAA and shading, and there were significant differences in the mRNA copy number among three Chss, between two Chis, and two F3hs during the coloration of grape berry skins.
Journal ArticleDOI
Expression of the flavonoid 3′-hydroxylase and flavonoid 3′,5′-hydroxylase genes and flavonoid composition in grape (Vitis vinifera)
TL;DR: Whether the transcription of these genes controls the flavonoid composition of Grape accumulates three classes of flavonoids, as well as their mRNA levels, which indicate other mechanisms in addition to gene transcription are expected to control the composition of each flavonoidal class.
Journal ArticleDOI
Generation and properties of ascorbic acid-deficient transgenic tobacco cells expressing antisense RNA for L-galactono-1,4-lactone dehydrogenase
TL;DR: In this paper, the terminal step of Lascorbic acid (AsA) biosynthesis is catalyzed by the enzyme L-galactono-1,4-lactone dehydrogenase (EC 1.3, GalLDH).
Journal ArticleDOI
Changes in ascorbate oxidase gene expression and ascorbate levels in cell division and cell elongation in tobacco cells
Naohiro Kato,Muneharu Esaka +1 more
TL;DR: It is proposed thatAAO expression and production of dehydroascorbate are under the control of the cell cycle and that AAO may function apoplastically as an ascorbate oxidizer in the process of cell elongation.
Journal ArticleDOI
Suppressed expression of the apoplastic ascorbate oxidase gene increases salt tolerance in tobacco and Arabidopsis plants
Atsuko Yamamoto,Md. Nazmul H. Bhuiyan,Rungaroon Waditee,Yoshito Tanaka,Muneharu Esaka,Kazuko Oba,Andre T. Jagendorf,Teruhiro Takabe +7 more
TL;DR: It is suggested that the suppressed expression of apoplastic AAO under salt-stress conditions leads to a relatively low level of hydrogen peroxide accumulation and a high redox state of symplastic and apoplastics ascorbate which, in turn, permits a higher seed yield.
