The key step is to prepare rare gibberellins by converting the m ore readily available gibberellins (G A 3, G A 4, G A 7 and G A 13) into their m ethyl esters. The D M F D M A is em ployed as an esterifying reagent to avoid the diazom ethane due to its toxic, explosive and hazardous nature. It is observed that D M F D M A apart from esterification can also be used as acetylating and epim erizin...

Gibberellic acid was tested for its effect on tumor induction by Agrobacterium tumefaciens in primary pinto bean (Phaseolus vulgaris) leaves in various stages of development. The hormone was found to promote tumor induction in partially aged leaves but did not effect tumor induction in very young leaves or in fully matured leaves. It is suggested that the natural loss of susceptibility to tumor...

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...

Gibberellic acid is a tetracyclic di-terpenoid molecule that acts as plant hormone by promoting the growth and development of plants. Gibberellins, one longest-known groups hormones, control several developmental signaling processes, such stem lengthening, germination, dormancy, flowering floral development, well senescence leaves fruits. Gibberellins can alter physiological including vegetativ...

Gibberellins modulate multiple aspects of plant behavior. The molecular mechanism by which these hormones are perceived and how this information is translated into transcriptional changes has been elucidated in vascular plants: gibberellins the nuclear receptor GID1, then interacts with DELLA proteins promote their degradation, resulting modification activity transcription factors DELLAs intera...
