Abstract:
Abstract Gibberellins are produced by all vascular plants and several fungal and bacterial species that associate with plants as pathogens or symbionts. In the 60 years since the first experiments on the biosynthesis of gibberellic acid in the fungus Fusarium fujikuroi, research on gibberellin biosynthesis has advanced to provide detailed information on the pathways, biosynthetic enzymes and their genes in all three kingdoms, in which the production of the hormones evolved independently. Gibberellins function as hormones in plants, affecting growth and differentiation in organs in which their

Abstract:
ABSTRACT The fungus Fusarium fujikuroi (Gibberella fujikuroi MP-C) produces metabolites of biotechnological interest, such as gibberellins, bikaverins, and carotenoids. Gibberellin and bikaverin productions are induced upon nitrogen exhaustion, while carotenoid accumulation is stimulated by light. We evaluated the effect of nitrogen availability on carotenogenesis in comparison with bikaverin and gibberellin production in the wild type and in carotenoid-overproducing mutants (carS). Nitrogen starvation increased carotenoid accumulation in all strains tested. In carS strains, gibberellin and bi

Abstract:
In 11-day-old flax seedlings, the level of endogenous gibberellins in roots decreased within 12 hours after the excision of cotyledons and the epicotyl; however, 24 to 48 hours after excision the gibberellin level increased again. The decrease in the gibberellin level within the first 12 hours after excision suggests a participation of the cotyledons and the epicotyl in the biosynthesis of endogenous gibberellins.

Abstract:
The vegetative forms of male (XY), female (XX), and hermaphrodite (XYh) papaya (Carica papaya L.) plants are phenotypically identical. However, the flower and inflorescence morphology of each sex type is unique. Gynodioecious varieties SunUp, SunUp Diminutive mutant, and dioecious AU9 were used to test the response of papaya to gibberellic acid (GA3). Exogenous applications of GA3 on female and hermaphrodite flowers of papaya did not yield any sex reversal phenotype but caused a significant increase in peduncle elongation and inflorescence branch number in all treated plants.

Abstract:
The scope of the microbiological transformation of ent-kaurenoid diterpenes by the fungus Fusarium (Gibberella) fujikuroi which utilise the ent-kaurene and ent-kauren-19-oic acid oxidases and the ring contraction of ring B to gibberellin is reviewed. Constraints arising from the presence of 3α, 15α and 18-hydroxyl groups are noted. The development of a group of potential plant growth regulators which inhibit the ring contraction step in gibberellin biosynthesis is described.

Abstract:
Petiole elongation of strawberry plants (Fragaria × ananassa) is modified by photoperiod, and gibberellins may mediate this response. To test the relationship further, we measured petiole growth dynamics under short and long days, in comparison with responses to paclobutrazol, which reduces gibberellin biosynthesis. Growth rate in short days was lower after 2 days, and at its maximum was 60% of long-day controls. Petiole length at maturity was 75%, and was accounted for primarily by decreased cell length. Subsequent leaves showed similar patterns, but in the third leaf, cell number was also re

Eucalyptusnitens (Dean & Maiden) Maiden grafts growing as espaliers at Ridgley, Tasmania, and Canberra, Australian Capital Territory, were treated with paclobutrazol as a single collar drench application. Umbel production was enhanced for 3 years at Ridgley and 2 years at Canberra. Canberra grafts were also treated by trunk injection, which proved effective only in the 1st year. Untreated grafts did not produce an appreciable number of umbels until year 3. Paclobutrazol reduced the level of endogenous gibberellins.

Abstract:
Using targeted expression of a constitutively active repressor of GA signalling Susana Ubeda-Tomas et al., (2007) demonstrated that GA action in endodermal cells is necessary for correct root growth. However, GUS studies have shown the final and penultimate GA-biosynthetic genes are not expressed in the endodermis, indicating movement of GAs may be required. This study used the targeted mis-expression of GA degrading enzymes in Col-0 and the attempted targeted rescue of GA biosynthetic and signalling mutants, using the corresponding GA metabolic or signalling component, to gain an insight into

Abstract:
The aim of this work was to study the terpenoid biosynthesis and its regulation in the fungus Gibberella fujikuroi. This was facilitated by the use of a number of mutants of G. fujikuroi produced using UV radiation or N-methyl-N'-nitrosoguanidine and selected mainly by mutation in colour and photoregulation (Avalos et al., 1985). A separation procedure for the carotenoids was devised and up to 9 carotenoids were isolated. Their levels were measured in wild type G. fujikuroi and 4- of the mutants in both light and dark grown conditions. From this a carotenogenic pathway for G. fujikuroi was pro
