2. Shows an average plant with a moderate amount of gibberellins, and an average internode length. 3. Shows a plant with a large amount of gibberellins and so has a much longer internode length, because gibberellins promote cell division in the stem. Gibberellins are involved in the natural process of breaking dormancy and other aspects of ...
In 1926, Japanese scientists observed that rice plants infected with Gibberella had abnormally long stems ("foolish seedling disease"). [1] A substance, gibberellin, was derived from this fungus. Gibberellin is a plant hormone that promotes cell elongation, flower formation, and seedling growth. [2] Gibberella fujikuroi on Gossypium hirsutum
Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, [1] the regulation of organ size, pathogen defense, [2] [3] stress tolerance [4] [5] and reproductive development.

Gibberellic acid (also called gibberellin A3 or GA 3) is a hormone found in plants and fungi. [1] Its chemical formula is C 19 H 22 O 6. When purified, it is a white to pale-yellow solid. Plants in their normal state produce large amounts of GA3. It is possible to produce the hormone industrially using microorganisms. [2]
Gibberella fujikuroi is a fungal plant pathogen. It causes bakanae disease in rice seedlings. Cotton infected with bakanae disease. Another name is foolish seedling disease. It gets that name because the seeds can be infected, leading to disparate outcomes for the plant. There are not many diseases that initiate similar symptoms as bakanae.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Plant-based eating is good for the planet, given that farming animals for food is known to be one of the big contributors to greenhouse gas emissions. Are there downsides to a plant-based diet?
Anton Lang showed that several long-day plants and biennials could be made to flower by treatment with gibberellin, even when grown under a non-flower-inducing (or non-inducing) photoperiod. This led to the suggestion that florigen may be made up of two classes of flowering hormones: Gibberellins and Anthesins. [18]
