What are they? The gibberellins make up a family of small organic compounds derived from a common 20-carbon precursor. They regulate growth and development in plants and their chemical structure superficially resembles that of steroid hormones. So far, more than 100 gibberellins have been identified. Fortunately, any one plant species produces only a few of the known gibberellins. Furthermore, ...

Gibberellins are compounds that produce a wide variety of growth responses in flowering plants. Among these responses are stimulation of shoot growth for many plant species,' root elongation in maize,2 induction of bolting and flowering in some biennial and long-day plants,3-resumption of normal growth in certain genetically dwarfed genotypes of maize,6 growth stimulation in dwarf strains of pe...

cellulolytic complex are enzymes capable of hydrolyzing cellulose. due to rapid growth in population and industrialization, most countries are required to produce more fuel. production of bioethanol from lignocellulosic biomass is very challenging due to environmental pollution by fossil fuels. cellulases play a significant role in biotechnological processes. the cost of production of cellulase...

Gibberellins are amongst the main plant growth regulators. Discovered over a century ago, interest in gibberellins research is growing due to their current and potential applications crop production role responses environmental stresses. In present review, knowledge on gibberellins’ homeostasis modes of action outlined. Besides this, complex interrelations between other regulators also describe...

Previously we reported the first example of peptide mimics of a small hydrophobic molecule, a phytohormone gibberellin. The second peptide mimic of gibberellin has been identified from random peptide libraries by its affinity to a type of catalyzing enzyme of gibberellins, which specifically recognizes bioactive gibberellins. These results suggest that even hydrophobic compounds can be mimicked...

Gibberellin production by Gibberella fujikuroi started only after the nitrogen source was depleted and ceased upon its renewal. Nitrogen repression of gibberellin biosynthesis is not an indirect effect of the growth arrest that follows the depletion of an essential nutrient because gibberellins were not produced upon depletion of phosphate. Mycelia produced gibberellins when suspended in a gluc...

The effects of 3-deoxygibberellin C (DGC) on the growth-promoting actions of gibberellins A(1), A(2), A(3), A(4), A(5), A(7), A(8), A(9), A(13), A(18), A(19), A(20), and A(23) (GAn) as well as 13-deoxygibberellin A(5) (deoxy-GA(5)) were tested with seedlings of gibberellin-deficient dwarf mutants (d(2) and d(5)) of maize (Zea mays L.). It was found that DGC promoted the actions of gibberellins ...
