The effect of various cytokinins and other factors on the protonemal celi divisions and the induction of gametophores in Ceratodon purpureus

open access: yesActa Societatis Botanicorum Poloniae, 2015
The cytokinins specifically induce formation of gametophore buds in the protonema of Ceratodon purpureus. The responsein this species is less sensitive than in Funaria hygrometrica, but is independent of light.

Hormone Profiles and Antioxidant Activity of Cultivated and Wild Tomato Seedlings under Low-Temperature Stress

open access: yesAgronomy, 2021
Low temperature is a major limiting factor for the growth and reproduction of some plant species, such as tomato. So far, few studies have been conducted on the effects of low temperature, and the mechanisms of plants’ response to this type of stress is ...

Cytokinins

open access: yesYAKUGAKU ZASSHI, 1994
Cytokinins which promote cell division and cell differentiation of plants are structurally classified into two groups: purine-type cytokinins and phenylurea-type cytokinins. Structural modification of the two types led a potent cytokinin, N-(2-chloro-4-pyridyl)-N'-phenylurea (forchlorfenuron). Structure-activity relationship was discussed.

Virulence Factors of the Fungal Pathogen Stagonospora nodorum Manipulate Hormonal Signaling Pathways in Triticum aestivum L. by Regulating Host Plant MicroRNA Expressions

open access: yesFrontiers in Bioscience-Elite, 2023
Background: Currently, the role of microRNAs in plant immune responses is being actively studied. Thus, our aim was to research the effect of Stagonospora nodorum (Berk.) NEs SnToxA and SnTox3 on the expression of miRNAs involved in the wheat–S.

Influence of phase change within a 90-year-old Sequoia sempervirens on its in vitro organogenic capacity and protein patterns [PDF]

open access: yes, 1994
Shoot-tips collected from stump shoots at the base of a 90-year-old #Sequoia sempervirens# and from the crown of the same donor tree were compared in respect of their organogenic performance in in vitro conditions.

Tissue culture of oil palm : finding the balance between mass propagation and somaclonal variation [PDF]

open access: yes, 2019
The oil palm (Elaeis guineensis Jacq.) is typically propagated in vitro by indirect somatic embryogenesis, a process in which somatic cells of an explant of choice are, via an intermediate phase of callus growth, induced to differentiate into somatic ...

Biosynthesis of Cytokinins in Cytokinin-Autotrophic Tobacco Callus [PDF]

open access: yesProceedings of the National Academy of Sciences, 1973
A cytokinin-autotrophic strain of tobacco callus contained cytokinin-active compounds with chromatographic mobilities on Sephadex LH-20 corresponding to ribosylzeatin, zeatin, and 6-Δ 2 -isopentenylaminopurine. Zeatin, the apparent major cytokinin, was estimated to be present at a concentration of 10 -4

Cytokinin Sensing in Bacteria

open access: yesBiomolecules, 2020
Although it has long been known that bacteria detect and react to plant chemicals to establish an interaction, the cellular signaling mechanisms involved in these perception processes have hitherto remained obscure.
