“…The Le gene was shown to encode a gibberellin 3β-hydroxylase which converts GA 20 to the bioreactive GA 1 . The reduced activity in the le mutant was associated with an alanine to threonine substitution in the amino acid sequence of the enzyme [104]. The sites of action associated with the ls, lh and na genes on the GA biosynthesis pathway were also identified [145].…”

“…The wild-type pea (Pisum sativum) line NGB5839 used for this research is a dwarf derivative of 'Torsdag' carrying the le-3 and hr mutations (Lester et al, 1999;Weller et al, 2012). All plants were grown in a 1:1 mixture of dolerite chips and vermiculite topped with potting mix and received nutrient solution weekly.…”

The early steps in the gibberellin (GA) biosynthetic pathway are controlled by single copy genes or small gene families. In pea (Pisum sativum L.) there are two ent-kaurenoic acid oxidases, one expressed only in the seeds, while ent-copalyl synthesis and ent-kaurene oxidation appear to be controlled by single copy genes. None of these genes appear to show feedback regulation and the only major developmental regulation appears to be during seed development. During shoot maturation, transcript levels do not change markedly with the result that all the three genes examined are expressed in mature tissue, supporting recent findings that these tissues can synthesise GAs. It therefore appears that the regulation of bioactive GA levels are determined by the enzymes encoded by the 2-oxoglutarate-dependent dioxygenase gene families controlling the later steps in GA biosynthesis. However the early steps are nonetheless important as a clear log/linear relationship exists between elongation and the level of GA1 in a range of single and double mutants in genes controlling these steps.
