TL;DR: Isozyme investigations reyealed varying patterns in growing and differentiating callus and a correlation between isozyme expression and differentiation process is discussed.

TL;DR: Results suggest that one PG subunit could be the product of the female-specific DNA which, consequently, cannot be a feminizing allele.

TL;DR: High performance liquid chromatography analysis of immunoaffinity-purified extracts of mycelia of Amanita muscaria, and the Amaranthus bioassay of the eluted fractions, revealed that zeatin was the most affected, exhibiting a reduction of about 90%.
Abstract: High performance liquid chromatography analysis of immunoaffinity-purified extracts of mycelia of Amanita muscaria, and the Amaranthus bioassay of the eluted fractions, revealed the following seven cytokinins: zeatin, zeatin riboside, zeatin N-9-glucoside, dihydrozeatin, dihydrozeatin riboside, isopentenyl adenine, and isopentenyl adenosine. The decreased growth of aluminum-treated mycelia correlated with a 35% decrease in the total amount of the cytokinins. Among individual cytokinins, zeatin was the most affected, exhibiting a reduction of about 90%. The results are compared with previous investigations of aluminum effects on cytokinins in the mycelia of Lactarius piperatus, whose growth is stimulated by aluminum.

TL;DR: Seedlings of O. violaceus were cultured on MS media and treated at low temperature and flower induction of seedlings in vitro originated from germinated seeds and could be accelerated when MS media was used with a reduced amount of NH4NO3.
Abstract: Seedlings of O. violaceus were cultured on MS media and treated at low temperature. Cold treatment at 5–7 °C for more than 7 days was needed for flower induction of seedlings in vitro originated from germinated seeds. When cultured on MS media supplemented with 2.5 mg l−1 zeatin and 2 mg l−1 gibberellin (GA3), seedlings in vitro did initiate flowers without cold treatment. When MS media was used with a reduced amount of NH4NO3, flower induction of seedlings in vitro could be accelerated.

TL;DR: Results in terminal buds showed increasing amounts of indole-3-acetic acid (IAA) the more reinvigorated the plant material was, whereas an enhancement in total cytokinins levels was observed in axillary buds, corroborating previous findings in which the ratio of isopentenyladenine-type to zeatin-type Cks was reported as an ageing and vigour index.
