Drought Induction of Arabidopsis 9-cis-Epoxycarotenoid Dioxygenase Occurs in Vascular Parenchyma Cells1[W][OA]
The regulation of abscisic acid (ABA) biosynthesis is essential for plant responses to drought stress. In this study, we examined the tissue-specific localization of ABA biosynthetic enzymes inExpand

Tissue-Specific Localization of an Abscisic Acid Biosynthetic Enzyme, AAO3, in Arabidopsis1
Arabidopsis aldehyde oxidase 3 (AAO3) is an enzyme involved in abscisic acid (ABA) biosynthesis in response to drought stress. Since the enzyme catalyzes the last step of the pathway, ABA productionExpand

Phytochrome- and Gibberellin-Mediated Regulation of Abscisic Acid Metabolism during Germination of Photoblastic Lettuce Seeds1[OA]
Germination of lettuce (Lactuca sativa) ‘Grand Rapids’ seeds is regulated by phytochrome. The action of phytochrome includes alterations in the levels of gibberellin (GA) and abscisic acid (ABA). ToExpand

Germination of photoblastic lettuce seeds is regulated via the control of endogenous physiologically active gibberellin content, rather than of gibberellin responsiveness
Phytochrome regulates lettuce (Lactuca sativa L. cv. Grand Rapids) seed germination via the control of the endogenous level of bioactive gibberellin (GA). In addition to the previously identifiedExpand

Light effects on endogenous levels of gibberellins in photoblastic lettuce seeds
Gibberellin A1 (GA1), 3-epi-GA1 GA17, GA19, GA20, and GA77 were identified by Kovats retention indices and full-scan mass spectra from gas chromatography-mass spectrometry analysis of a purifiedExpand

Antitumor Activities of Edible Mushrooms by Oral Administration
Abstract Antitumor activities of edible mushrooms were investigated by breeding mice with the feed containing 10-30% (w/w) powdered fruit bodies. In allogeneic tumor systems (Sarcoma-180 in ICRExpand

Deactivation of Gibberellin by 2-Oxidation during Germination of Photoblastic Lettuce Seeds
Gibberellin (GA) plays an important role in the induction of germination of photoblastic lettuce (Lactuca sativa L. cv. Grand Rapids) seeds. We have previously shown that gene expression of a GAExpand

The endogenous level of GA(1) is upregulated by high temperature during stem elongation in lettuce through LsGA3ox1 expression.
Bolting of lettuce is promoted by high temperatures. Gibberellins (GAs) play an important role in the bolting of several plant species, and it has been reported that exogenous GAs induce bolting andExpand
