Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance to it.

Gibberellic acid, which was the first gibberellin to be structurally characterized, is GA 3. [6] As of 2020, [5] there are 136 GAs identified from plants, fungi, and bacteria. [1] [6] [5] Gibberellins are tetracyclic diterpene acids. There are two classes, with either 19 or 20 carbons. The 19-carbon gibberellins are generally the biologically ...

吉貝素 （英語： gibberellin，簡稱为 GA）也称 徒長素 、 激勃素 、 吉贝素 （因提取自 赤霉菌 而得名），是一種 植物激素，主要由植物未成熟的種子、幼根及幼芽產生。 其主要調節生長並影響各種發育過程，包括促進莖的伸长、 發芽 、 復甦種子 、 開花 、性別表現，抑制葉和果實的老化。 [1] 到2020年為止已發現至少136種類似結構的吉貝素化學物。 [1] 吉貝素化學物用A 1 （GA 1）到A 136 （GA 136）的方式命名，數字依照發現的先後順序。 1926年， 臺灣總督府中央 …

Gibberellic acids are diterpene plant hormones that are biosynthesized from geranylgeranyl diphosphate, a common C20 precursor for diterpenoids, which control diverse aspects of growth and development including seed germination, stem elongation, flowering, fruit development, and the regulation of gene expression in the cereal aleurone layer.

It has been almost a century since biologically active gibberellin (GA) was isolated. Here, we give a historical overview of the early efforts in establishing the GA biosynthesis and catabolism pathway, characterizing the enzymes for GA metabolism, and …

Gibberellic acid (GA), a plant hormone stimulating plant growth and development, is a tetracyclic di-terpenoid compound. GAs stimulate seed germination, trigger transitions from meristem to shoot growth, juvenile to adult leaf stage, vegetative to flowering, determines sex expression and grain development along with an interaction of different ...

2018年11月5日 · Gibberellic acid (GA) is a weak acid that works as a growth hormone in plants. These acids, also called gibberellins, affect the growth of shoots, leaves, flowers and reproductive organs in plants. Gibberellic acid has been used for several decades in agriculture to control and improve crop yields.

2024年1月1日 · Gibberellic acid (GA), a tetracyclic diterpenoid molecule, is a plant hormone that encourages plant development and growth. GAs promote a variety of environmental processes, including sex expression, grain formation, vegetative to flowering, juvenile to adult leaf stage, transition from meristem to shoot growth, and light, temperature, and water.

2020年7月11日 · The most abundant gibberellin present in F. fujikuroi and the first to be structurally characterized is gibberellin A 3, which is also known as gibberellic acid (Curtis and Cross 1954). This gibberellin is produced on an industrial scale in fungal cultures for application in agriculture, the largest use being in the production of seedless ...
