The plant hormone abscisic acid (ABA) induces a morphological change from green vegetative cells to red cyst cells, of Haematococcus pluvialis containing carotenoids, in plate culture. Long-lasting analogs of ABA, (+)-8′,8′,8′-trifluoro and (+)

Plant growth retardants (PGRs) reduce the shoot growth of plants by inhibiting gibberellin biosynthesis. In this study, we performed detailed analyses of the inhibitory effects of PGRs on Arabidopsis abscisic acid (ABA) 8'-hydroxylase, a major ABA ca

We designed and synthesized AHI4 that has an axial hydroxyl group instead of geminal methyl groups at C-6' of AHI1, previously reported as a lead compound for the development of non-azole inhibitors of ABA 8'-hydroxylase. (+)-AHI4 competitively inhib

(1′S*,2′S*)-(±)-6-Nor-2′,3′-dihydro-4′-deoxo-ABA (2) was designed and synthesized as a candidate lead compound for developing a potent and specific inhibitor of ABA 8′-hydroxylase. This compound acted as an effective competitive inhibito

Methyl ester of abscisic acid (ABA), a plant hormone, gives a dehydrated ion at m/z 260 in electron ionization mass spectrometry (EI–MS). This dehydrated ion had been considered to be derived only from the elimination of the tertiary hydroxyl group

Plant hormone abscisic acid (ABA) is an important factor for conferring drought stress resistance on plants. Therefore, small molecules that regulate ABA levels in plants can be useful both for investigating functions of ABA and for developing new pl

8'-O-(3-Hydroxy-3-methylglutaryl)-8'-hydroxyabscisic acid is a stable conjugate of the first metabolite of abscisic acid, 8'-hydroxyabscisic acid, that is spontaneously isomerized to phaseic acid. The chirality of the 3-hydroxy-3-methylglutaryl group

We synthesized 5'alpha,8'-cycloabscisic acid (CycloABA), a highly potent and long-lasting abscisic acid (ABA) analogue, by a different method from that reported before. CycloABA fed to radish seedlings had more metabolic tolerance than ABA. The major

Germination of lettuce (Lactuca sativa L. cv. 'Grand Rapids') seeds was inhibited at high temperatures (thermoinhibition). Thermoinhibition at 28 degrees C was prevented by the application of fluridone, an inhibitor of abscisic acid (ABA) biosynthesi
