Gibberellin Metabolism in Maize (The Stepwise Conversion of Gibberellin A12-Aldehyde to Gibberellin A20.
The stepwise metabolism of gibberellin A12-aldehyde (GA12-aldehyde) to GA20 is demonstrated from seedling shoots of maize (Zea mays L.). The labeled substrates [13C,3H]GA12-aldehyde, [13C,3H]GA12, [14C4]GA53, [14C4/2H2]GA44, and [14C4/2H2]GA19 were fed individually to dwarf-5 vegetative shoots. Both [13C,3H]GA12-aldehyde and [13C,3H]GA12 were also added individually to normal shoots. The labele...
متن کاملGibberellin biosynthesis from gibberellin A12-aldehyde in endosperm and embryos of Marah macrocarpus.
Soluble enzyme preparations from embryos and endosperm of Marah macrocarpus (previously Echinocystis macrocarpa) were incubated with [14C4]gibberellin(GA)12-aldehyde, [14C4]GA12, [14C1] GA9, 2,3-didehydro[14C1]GA9, [14C1]GA20, and [17-13C, 3H]GA5. Embryo preparations converted GA12-aldehyde, GA12, and GA9 to GA4 and GA7; 2,3-didehydroGA9 to GA7; GA5 to GA3; and GA20 (incompletely) to GA1 and GA...
متن کاملGibberellin metabolism and signaling.
Gibberellins (GAs) are a family of plant hormones controlling many aspects of plant growth and development including stem elongation, germination, and the transition from vegetative growth to flowering. Cloning of the genes encoding GA biosynthetic and inactivating enzymes has led to numerous insights into the developmental regulation of GA hormone accumulation that is subject to both positive ...
متن کاملGibberellin homeostasis in tobacco is regulated by gibberellin metabolism genes with different gibberellin sensitivity.
Gibberellins are phytohormones that regulate growth and development of plants. Gibberellin homeostasis is maintained by feedback regulation of gibberellin metabolism genes. To understand this regulation, we manipulated the gibberellin pathway in tobacco and studied its effects on the morphological phenotype, gibberellin levels and the expression of endogenous gibberellin metabolism genes. The o...
متن کاملMetabolism of gibberellin a(12)-7-aldehyde by soybean cotyledons and its use in identifying gibberellin a(7) as an endogenous gibberellin.
The level of gibberellin(GA)-like material in cotyledons of soybean (Glycine max L.) was highest at mid-pod fill-about 10 nanograms GA(3) equivalents per gram fresh weight of tissue, assayed in the immersion dwarf rice bioassay. This amount is about 1000-fold less than levels in Pisum and Phaseolus seed, other legume species whose spectrum of endogenous gibberellins (GAs) is well known. The met...
