Proc Natl Acad Sci USA. 96:1999;4698-4703. A major catabolic step for GA is 2β-hydroxylation, a reaction catalyzed by 2-oxoglutarate-dependent dioxygenases. A cDNA encoding the enzyme was isolated by the use of functional screening of a cDNA library from developing cotyledons of Phaseolus coccinieus L. The encoded protein expressed in E. coli has 2β-hydroxylase and catabolite formation activity and the enzyme was named as GA 2-oxidase. The homologs were also isolated from Arabidopsis.

Plant Cell. 10:1998;2115-2126. Arabidopsis GA4 and GA4H (for GA4 homolog) both encode GA 3β-hydroxylases. The newly isolated GA4H gene was predominantly expressed in germinating seeds. Both GA4 and GA4H genes were induced by red light. In the phyB-deficient phyB-1 mutant, GA4H expression was not induced by red light, but GA4 expression still was, indicating that red light-induced GA4 and GA4H expression is mediated by different phytochromes. Unlike GA4, GA4H is not regulated by negative feedback from active GAs.

This short communication shows, by using grafting experiments between antisense phyB (anti-PHYB) and wild-type potato plants, that phyB controls the production in the leaves of a graft-transmissible inhibitor of tuber formation. The anti-PHYB plants tuberize under non-inductive conditions because they produce or transport less inhibitor.
41. Carrera E, Jackson SD, Prat S Feedback control and diurnal regulation of gibberellin 20-oxidase transcript levels in potato. Plant Physiol. 119:1999;765-773. Three GA 20-oxidases were cloned from potato, all being expressed in the stolons and one of them (StGA20ox1) at high levels in the leaves. It was found that the content of StGA20ox transcripts in the leaves follows a diurnal rhythm under inductive (SD) conditions of tuberization. Under non-inductive (30 min night-break or LD) conditions another peak of St20ox1 and St20ox2 transcripts appears, suggesting that the diurnal rhythm of endogenous GAs may play a role in the control of tuberization.

43. 20 peaks in wild-type plants grown under inducing conditions were similar to those of phyB plants, which flowers almost independently of photoperiodic conditions. The photoperiod also affects the pattern of GA content in phyB plants associated to its effect on flower initiation.
