The Relationship between AGAMOUS and Cytokinin Signaling in the Establishment of Carpeloid Features

Plants, 2021
Gynoecium development is dependent on gene regulation and hormonal pathway interactions. The phytohormones auxin and cytokinin are involved in many developmental programs, where cytokinin is normally important for cell division and meristem activity ...

Cytokinins

YAKUGAKU 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.

Probing the Unknowns in Cytokinin-Mediated Immune Defense in Arabidopsis with Systems Biology Approaches [PDF]

, 2014
Plant hormones involving salicylic acid (SA), jasmonic acid (JA), ethylene (Et), and auxin, gibberellins, and abscisic acid (ABA) are known to regulate host immune responses.

Identification and characterization of the first cytokinin glycosyltransferase from rice

Rice, 2019
Background Cytokinins are one of the five major hormones families in plants and are important for their normal growth and environmental adaptability. In plants, cytokinins are mostly present as glycosides in plants, and their glycosylation modifications ...

Characterization of a cytokinin-binding protein locus in Mycobacterium tuberculosis

Journal of Bacteriology
Cytokinins are adenine-based hormones that have been well-characterized in plants but are also made by bacteria, including the human-exclusive pathogen Mycobacterium tuberculosis. Like plants, M.

ACAULIS5 Is Required for Cytokinin Accumulation and Function During Secondary Growth of Populus Trees

Frontiers in Plant Science, 2020
In the primary root and young hypocotyl of Arabidopsis, ACAULIS5 promotes translation of SUPPRESSOR OF ACAULIS51 (SAC51) and thereby inhibits cytokinin biosynthesis and vascular cell division.

Single‐cell Transcriptome Profiling Reveals Gene Regulatory Networks and Key Genes in the Root Epidermis and Cortical Cells Associated with Early Nodulation in Glycine Max

Advanced Science, EarlyView.
Single‐cell transcriptomics of soybean roots soon after rhizobial inoculation reveals epidermal and cortical cell‐specific programs and gene‐regulatory networks acting in symbiosis establishment. We identify an ethylene‐driven regulatory circuit involving WRKY6.3/6.4 transcription factors targeting select Nod19 genes that promotes infection‐thread ...

Petal size is controlled by the MYB73/TPL/HDA19-miR159-CKX6 module regulating cytokinin catabolism in Rosa hybrida

Nature Communications, 2023
The size of plant lateral organs is determined by well-coordinated cell proliferation and cell expansion. Here, we report that miR159, an evolutionarily conserved microRNA, plays an essential role in regulating cell division in rose (Rosa hybrida) petals

Nodulating Legumes Are Distinguished by a Sensitivity to Cytokinin in the Root Cortex Leading to Pseudonodule Development

Frontiers in Plant Science, 2019
Root nodule symbiosis (RNS) is a feature confined to a single clade of plants, the Fabids. Among Fabids capable of RNS, legumes form root cortex-based nodules in symbioses with rhizobia, while actinorhizal species form lateral root-based nodules with ...

Cytokinin Response Factor 9 Represses Cytokinin Responses in Flower Development

, 2023
A multi-step phosphorelay system is the main conduit of cytokinin signal transduction. However, several groups of additional factors that also play a role in this signaling pathway have been found—among them the Cytokinin Response Factors (CRFs ...
