We previously found a chemical, designated as NJ15, which inhibited both auxin and brassinosteroid responses in dark-grown Arabidopsis. To study its mode of action, we performed a phenotypic screening of NJ15-low-sensitive lines among mutant pools of

Helminthosporol was isolated from a fungus, Helminthosporium sativum, as a natural plant growth regulator in 1963. It showed gibberellin-like bioactivity that stimulated the growth of the second leaf sheath of rice. After studying the structure–act

The role of endogenous gibberellin (GA) in the flowering of the short-day plant, Pharbitis nil, was investigated by using uniconazole, which is a specific inhibitor of GA biosynthesis. Both the endogenous GA level and flowering response decreased wit

Qualitative and quantitative analyses of endogenous jasmonoids were done by liquid chromatography/ selected ion monitoring (LC-SIM) using deuterium-labeled compounds as internal standards. To prove the practicality of this way of analyzing the conten

The endogenous gibberellins (GAs) of rice were analyzed during seed germination and during the regeneration of plant lets from embryogenic cells. Four 13-hydroxylated (13-OH) GAs (GA53, GA19, GA20, and GA1) were identified by combined gas chromatogra

Gibberellin A8 (GA8), GA17, GA29, GA44, and GA53 were identified from the shoots of Phyllostachys edulis, together with previously identified GA1 GA19, and GA20, and the occurrence of a 2β-ydroxy-GA53-like compound was suggested. An experiment on sh

Abscisic acid (ABA) and indole-3-acetic acid (IAA) were identified by full-scan GC-MS in phloem exudates collected from cotyledons of Pharbitis nil Chois., strain Violet. The occurrence of gibberellin A1 (GA1), GA19, and GA20 was also demonstrated by

Uniconazole applied to cotyledons inhibited the flowering response in Pharbitis nil. The application of gibberellin A1 (GA1) to cotyledons overcame the effect of uniconazole and restored the flowering response. The transport of GA1 from cotyledons to

Gibberellin A1 (GA1), GA15, GA19, GA20, GA29, GA44, and abscisic acid (ABA) were identified from vegetative shoots of Japanese cherry (Prunus spachiana Kitamura f. ascendens Kitamura, Edo-higan) by full-scan GC-MS. GA4, GA9, GA34, and GA53 were also

The endogenous levels of gibberellins (G As) and abscisic acid (ABA) were investigated during the germination of barley seeds. The level of GA1 was highest on the second day of germination, while that of ABA was lowest on the first day. These results
