PlantsAlfalfa (Medicago sativa L.) is a globally significant forage crop with notable economic value. Gibberellins (GA3) promote dormancy breaking and early germination whereas auxins (IAA) predominantly influence bud regeneration.

Effect of cotyledons and epicotyl upon the activity of endogenous gibberellins in roots of flax (Linum usitatissimum L.) seedlings [PDF]
Acta Agrobotanica, 2013 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.

Bacterial Gibberellins Induce Systemic Resistance of Plants
International Journal of Secondary Metabolite, 2014 It is generally agreed today that some rhizosphere bacteria can ensure induced systemic resistance to pathogens. In this paper we tested the ability of gibberellins produced by rhizosphere non-pathogenic bacteria Pseudomonas aurantiaca to induce systemic

Gibberellins of Sugarcane [PDF]
Plant Physiology, 1966 In our hands a phosphate buffered celite column has given an adequate separation of GA(1) and GA(3). These 2 gibberellins are normally very difficult to separate. Young sugarcane growing under moisture stress contains at least 2 gibberellin-like substances. One is suspected to be GA(5). The other is unknown but has high activity in the barley endosperm

Gibberellin Homeostasis in Tobacco is Regulated by Gibberellin Metabolism Genes with Different Gibberellin Sensitivity [PDF]
Plant and Cell Physiology, 2008 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 ...

Gibberellin Metabolism in Maize (The Stepwise Conversion of Gibberellin A12-Aldehyde to Gibberellin A20 [PDF]
Plant Physiology, 1996 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.

A technique for the measurement of gibberellins and its application to the xylem sap of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] [PDF]
An understanding of the gibberellins present in Douglas-fir is essential to understanding and controlling the growth and development of this species. A technique was developed which permits the separation of certain gibberellins with high performance ...

Trails to the gibberellin receptor, GIBBERELLIN INSENSITIVE DWARF1 [PDF]
Bioscience, Biotechnology, and Biochemistry, 2016 Abstract The researches on the identification of gibberellin receptor are reviewed from the early attempts in 1960s to the identification of GIBBERELLIN INSENSITIVE DWARF1 (GID1) as the receptor in 2005. Unpublished data of the gibberellin-binding protein in the seedlings of adzuki bean (Vigna angularis) are also included, suggesting ...
